A ‘road map’ might be an inappropriate term for a ‘river’ rejuvenation plan. Thus I am using the term, a ‘river map’.

It is well known that despite the Ganga Action Plan (GAP) being in place since the year 1985 and the Supreme Court adjudicating public interest litigation on it since 1993 the river has become increasingly sick with some stretches notably in Kanpur deserving a biologically ‘dead’ status. So it came as a huge sign of hope when the Prime Minister Modi took upon Ganga rejuvenation as a personal mission and appointed Sushri Uma Bharti, a well known Ganga devotee and activist as the Union Minister of the renamed Ministry of Water resources, River development and Ganga rejuvenation. Soon the Finance Minister in the new government allocated financial resources to the tune of Rs 2037 Crores in the name of Nemami Gange (devotional bow to river Ganga) a flagship scheme of the new government, which is aimed at the rejuvenation of river Ganga.

Yet in recent days the Supreme Court time and again has chided the state on the lack of a sound action plan for its avowed objective of a rejuvenated river Ganga. So much so that it once, in an obvious exasperation on the state’s ‘business as usual’ approach to the issue, commented that “it might well be another 200 years before Ganga is actually rejuvenated”? Clearly notwithstanding its firm intent, the state continues to struggle with defining a ‘road (river) map’ that could while convincing the highest court in the land of its utility, set a clear and effective action plan on the ground for a rejuvenated Maa (mother) Ganga?

REJUVENATION

Let us try and see what does Ganga really require for its rejuvenation?

Term ‘rejuvenation’, which includes restoration, is a return of any living entity from what it is today to an agreed state of previous health and wellness. To unravel that we might first need to understand ‘what is’ and ‘where is’ river Ganga?

Most planners tend to view Ganga as a 2500 km long river from Gaumukh to Ganga Sagar, passing through the cities of Uttarkashi, Devprayag, Rishikesh and Hardwar in the state of Uttarakhand; Kanpur, Allahabad and Varanasi in the state of Uttar Pradesh; Patna in the state of Bihar and Kolkata in the state of West Bengal before merging with the sea in the Bay of Bengal.

Herein, we understand lay the first fundamental planning mistake. For if Ganga were a simple linear entity as planners hold, then King Bhagirath would have unnecessarily carried out tapasya (penance) placating Lord Shiva to hold Ganga in his jata (matted locks) as she descended with massive force from the Brahm Lok (abode of the gods) with a presumed potential to wreck absolute havoc on the mrityu lok (earth) unless its speed had been broken. This mythical tale translates itself into an earthly reality whereby Ganga actually resides in each and every spring, in every water fall and in every stream that together form the vast network of its tributaries spread over its vast basin. So Ganga rejuvenation plan to make sense and desired impact must encompass actions to revive and restore all these numerous streams and tributaries.

The water fall is as much the Ganga (Photo by Yamuna Jiye Abhiyaan)

Small rivulets are as much Ganga (Photo by Yamuna Jiye Abhiyaan)

Thus any rejuvenation plan that fails to look at and factor in the Ganga’s larger reality is destined to fail, a la all the previous Ganga Action Plans. All put together Ganga is no less than 25,000 km in length, with a basin spread of some 1,086,000 sq km. (see map) These include areas in the states of Himachal Pradesh, Uttarakhand, Haryana, UP, Rajasthan, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand and West Bengal within and China, Nepal and Bangladesh outside of India. With such a huge basin, the rejuvenational challenge might appear daunting, leading to an alluring thought that let us first try and rejuvenate the 2500 km of the main stem of the river and then may be tackle the rest. This we believe to be a fatal approach akin to fire fighting, without getting to the root cause, with the most immediate organ of a cancer afflicted human resulting ultimately organ by organ in the latter’s demise. Let us not forget that a healthy river system is like a multi-strand chain which is ‘as strong as its weakest link’. Hence as long as even one tributary remains sick, there can be no respite or rejuvenation of Maa Ganga!

Ganga river basin (Source: http://en.wikipedia.org/wiki/Ganges_Basin)

In other words there is no single river Ganga. It is actually ‘Ganga Rivers’ spread all over its basin and carrying names like the Yamuna; Ramganga; Gomti; Mahakali (Ghaghara); Son; Gandak, Koshi etc with each in turn having their own network of rivers and their rejuvenational requirements, since over time majority of them have as well gone ‘sick’.

RIVER INHIBITING PROJECTS

Some might ask, but then what could be done with tributaries lying or originating in Nepal, Bangladesh or in China? A lot actually, beginning with not promoting or supporting river ‘inhibiting’ projects there and then taking lead in a common futures dialogue (an International Ganga Rivers Commission) program on Ganga as the Ganga rivers are in need of rejuvenation there as well.

Dwelling more on what are the river ‘inhibiting’ projects we are led to what constitutes a river’s integrity?

A ‘healthy’ river must ‘run’ freely and must ‘flood’ freely. (Floods in Indian rivers are natural monsoonal occurrence which could become devastating when obstructed).

That is its longitudinal and lateral connectivities must not be allowed to be compromised through manmade structures like dams, barrages and embankments. Such connectivities are essential for a river system to fulfill its ecological roles of transport of water, sediment and energy from source to the sea; recharge of ground water; provision of habitat to aquatic and riparian biota and completion of the water cycle.

In other words, a healthy river is essentially an ‘aviral’ (unbroken in its various dimensions) river. Thus the key challenge and objective of any Ganga rejuvenation plan has to be first and foremost its restoration back to a truly ‘aviral’ state.

FIVE STEPS

Accordingly the following five steps are suggested as the ‘river map’ to a rejuvenated river Ganga.

Step 1 – Establish local level Ganga rejuvenation governance systems to ensure participatory bottom up planning and action plan execution. Support this with the establishment of a Ganga Rivers governance research centre.

Step 2 – Prioritise tributaries (Ganga Rivers) for restorative actions on the basis of their current level of threats and develop restorative action plans utilizing the governance systems as mentioned in step 1.

Step 3 – Establish through a participatory process a desired state of the rejuvenated Ganga; devise a national Ganga rivers policy and a Ganga rejuvenation law. Initiate dialogue with the Ganga nations for an International Ganga rivers Commission.

Step 4 – Review through independent experts, all past, present and planned river ‘inhibiting’ projects on the Ganga Rivers and then either re-design them to become river friendly or decommission / drop them. There should be a moratorium placed on any new structure (barrage, HEP, embankment) on Ganga Rivers till such time that all local level options of water harvesting and energy production (including solar and wind) have been exhausted with a policy that river waters and HEPs shall be the last resort for meeting such needs.

Step 5 – Set a time bound plan of action for ensuring aviral and wholesome Ganga ‘rivers’, with plans for ensuring their flows (water, sediment and energy) as well as the restoration of their catchment, flood plains and the associated biodiversity (aquatic, riparian and terrestrial).

The steps as suggested above are not sequential in nature and many could progress concurrently.

To a query “what then about the hydropower and water supply for fulfilling various human needs”, the response is twofold.

Firstly, this is the Ganga rejuvenation plan based on what Ganga Rivers need for the restoration of their health. Secondly, hydro-power generation and water diversion cannot be in excess of the thresholds as defined by the rejuvenational requirements of the healthy Ganga Rivers.

A rejuvenated Ganga has to be seen as a ‘provider within strict limits’ (as enunciated by the Prime Minister Modi on the banks of Maa Ganga in Varanasi, when he defined what a Maa (mother) is) and not what we in our flawed wisdom might wish to harness from her, with little concern for her deteriorating health and in disregard to the principle of inter-generational equity.

RIVER AND SEWER

The Indian state under the Ganga Action Plan had been investing time, money and efforts to restore the river Ganga through creation of pollution abatement infrastructure like the Sewage treatment plants (STPs) and the Effluent treatment plants (ETPs) in various cities and industries on the river in the name of ‘river cleaning’ with little ameliorative impact on the health of the river. In our understanding despite the poor maintenance being the cause of the failure of the created infrastructure, this approach to river restoration is fundamentally misplaced and hence wrong.

We believe that our rivers require restoration (based on the steps suggested before) of their ecological integrity in terms of their freedom to ‘flow’ and ‘flood’. Once thus freed, they possess all the power of self cleansing, subject to the observance of the fundamental principle of no mixing of ‘sewer’ with ‘river’. Here by ‘sewer’ we mean all kinds of grey water produced both by the cities and the industries.

Thus there is no mention of any river ‘cleaning’ or creation of STPs / ETPs as part of the suggested Ganga rejuvenation plan. The installation of such infrastructure is we believe to be an essential element of the process of urbanization and industrialization whereby the grey water from the cities and industries is converted into utilizable water for recycle and reuse to meet the non potable water needs both of the cities and the industries. But to do so in the name of river cleaning is in our understanding an ostrich like approach which takes away the attention and resource allocation from the real needs of river restoration based on the sound principles of river science.

Prime Minister Modi’s another oft quoted aphorism of “Zero defect and zero effect/ impact” should be made applicable not just to good manufacturing practices but also to good urban management practices with mandatory zero impact on any river that happens to pass by. AMEN!

World Rivers Day and Ganga: A look at Farakka Barrage and other such calamities

September 29, 2014April 28, 2015 SANDRP6 Comments

Last Sunday of every September is celebrated as ‘World Rivers Day’. It is a recent phenomenon, but in many senses more significant than World Water Day. While ‘Water’ is seen more as a resource than the life-blood of the global ecosystem, ‘River’ provides water with its ecological, social, cultural and spiritual context. One this day, SANDRP looks at India’s ‘National River’ Ganga. The river seems to be a symbol of all that is right and wrong with water governance in India. It depicts crystallisation of challenges faced by rivers across the country, albeit at a much larger scale. The rich canvass and the deep spiritual value of Ganga for many cultures make it more riveting. The new government at the centre has declared that rejuvenation of the Ganga River is one of its priorities. However, in addition to several infrastructure projects planned and ongoing on the river and its tributaries (Ganga is not just 2525 kms long river, its is more than 25,000 kms long, with all its tributaries), the new Government is planing to build a series of barrages on the River to make it navigable, from Haldia, at the mouth of Hooghly, a major distributary of the Ganga to Allahabad which is some 1620 kms upstream from Haldia. Before we go further into the advantages or the disadvantages of more barrages on Ganga, let us take a look at what one only existing Barrage on this 1620 km stretch of the river, The Farakka Barrage, has done to the river in the past 39 years since the Barrage was commissioned. Let us see how we have managed the issues which have arisen, how human lives have been impacted, what has been our response, how the main objective of building the barrage has been frustrated, how we have dealt with this realization, how the Barrage has furthered more conflicts and how a thriving fishing activity has been nearly killed by Farakka in the upstream as well as in the downstream. SANDRP visited the region of Farakka Barrage, Malda, Murshidabad, talked with the affected people, fisherfolk, authorities at the Barrage as well as the Director and other officials at the Central Inland Fisheries Research Institute (CIFRI) to understand the complex issues. Prior to detailed analysis, here’s looking at Ganga, Hooghly and Farakka in photos.

Farakka Barrage was commissioned in 1975 to transfer 40,000 cusecs ( Cubic Feet per second) of water from Ganga into its distributary Hooghly to save the Kolkata Port on the Hooghly from silting up. The barrage is just 16 kms upstream from Bangladesh border.

As a part of Farakka Barrage Project, an afflux bund was constructed over several rivers upstream of Farakka, like Choto Bhagirathi, Pagla, etc., to divert water into the Barrage. The complete diversion of water killed these rivers in the downstream, severely affecting people. Here we see Choto Bhagirathi flowing after many years, thanks to a pipeline and sluice sanctioned this year to supply meager water to the river. This does not help the fish though, there are hardly any left.

Not withstanding the anti-erosion works completed upstream the Farakka Barrage in Malda, the Ganga has deposited huge sediment load in the upstream of the barrage and this has accelerated the swing in its channel. The channel is swinging rapidly to the left bank, eroding and eating away thousands of hectares of villages, farms, mango plantations and chars (islands) in the way, endangering the Barrage itself. Although sediment-laden Ganga has a history of changing courses, this has been aggravated to a great extent by the sedimentation and obsrtuction caused by Farakka.

Even before you arrive at the heavily guarded Barrage, you can see the heavily silted river, with cattle grazing peacefully on islands (chars) just 500 meters-1 km upstream of the barrage. According to River Expert Kalyan Rudra, Farakka hordes nearly 350 million tonnes of sediment flow of Ganga every year in the upstream!!

The Barrage also severely affected navigation through the river. A separate ship lock was made on the Feeder Canal and it is managed by Inland Waterways Authority of India (IWAI). Hardly any ships pass through due to high sedimentation.

Fishermen upstream Farakka are a worried lot

Downstream the barrage, due to trapping of silt in the upstream, silt free water erodes banks with vengeance, especially the left bank. We saw several anti-erosion measures failing miserably in front of the river’s fury.

Anti erosion works get routinely swept away

Farakka has profoundly changed the character, sediment regime and flow of Ganga. It is affecting lives of lakhs of people in India and Bangladesh through cycles of erosion, sedimentation, floods and affected fishing. Our response to the issue has been dismal. We have not conducted a single review of costs, benefits and impacts of Farakka Project so far. In addition to Farakka , Lower Ganga (Narora), Middle Ganga, Upper Ganga Barrages (Bhimgoda), Kanpur Barrage, Hydropower projects in Uttarakhand and other upstream states have affected the river in most profound ways. If we want to rejuvenate the Ganga, we need to institute a credible independent review the existing Barrages, not plan new ones. May be we can begin with a demand for such a review for Farakka on urgent basis. One World Rivers Day, let us wish for a long and healthy flow for the Ganga River, a symbol of all flowing rivers in India!

Ganga and Varanasi’s Waste-water Management: Why has it remained such an Intractable Problem?

September 25, 2014November 9, 2015 SANDRP10 Comments

Guest blog by: Dr Kelly D. Alley (ALLEYKD@auburn.edu), Auburn University, USA

Varanasi is newsworthy these days, situated symbolically and politically in the new Prime Minister’s agenda. In his victory speech, the PM-elect Narendra Modi vowed to clean the sacred river Ganga. After assuming the office of Prime Minister, he reiterated the vow and pledged renewed efforts for Ganga cleanup.

Three months later, a skeptical Supreme Court reviewed the new government’s Ganga Plan and remarked that with this approach the river will not be cleaned in 200 years. The Supreme Court asked for the full details of the cleanup plan, and inserted its role as a monitor over central government plans. The government has reportedly submitted a new plan to the court, but no details are available yet in the public domain. However, from media reports, it seems the plan is not very different from what has been done in the name of the Ganga Action Plan so far.

As residents and sympathetic outsiders know, the wastewater problem in this sacred, ancient city is seemingly intractable. In order to implement lasting solutions to the recurring river pollution scenario, we need to investigate the current situation. I just completed a field trip to this special city that many call Banaras. I visited all the existing and planned components of the wastewater collection, treatment, and disposal system. In this article I will try to create a visual map of the wastewater infrastructure and management problems and define the current lines of command and control within the vast and overlapping water, environment, and public health bureaucracies. This should help to identify systemic problems in each that need to be addressed when charting a new direction.

The seemingly intractable problems of Ganga clean up (rejuvenation will need so much more than just a clean up) in Banaras can be divided into three categories. First, there are governance problems that are related to how decisions on technologies, scale, operators and siting are made. These include problems with the solicitation, selection, and implementation of projects, especially the design and construction and operation and maintenance of sewers, sewage pumping stations and sewage treatment plants. Second, there are serious infrastructure problems that are part of the complexity of this ancient city.

Third, there is a real electrical power supply problem. Securing continuous electrical power for sewage pumping stations and wastewater treatment facilities is a low priority, and emergency standby generators are not used when the grid-provided power is unavailable. As a result, the intermittent operation of sewage pumping stations and sewage treatment plants is ineffective in protecting water quality in Ganga and in provisioning safe drinking water and sanitation in Varanasi.

When the sewerage infrastructure is operated intermittently, the treatment technology cannot treat the wastewater adequately, and the concentration of contaminants and water quality indicators such as total suspended sewage solids (TSS) and biological oxygen demand (BOD), heavy metals, toxic organic compounds, and the Most Probable Number (MPN/100ml) of fecal coliform bacteria–indicating the presence of enteric waterborne disease pathogens in the treated effluent–remain high. So in a way providing partial power to a sewage treatment plant does not do the work and is therefore a largely inoperable, non-functional, sunk cost.

Governance

The Government of India established the Ganga Action Plan in 1986 to lead the way in river pollution control programs. In 2009, the Government declared the Ganga a national river and established the National Ganga River Basin Authority. The National Mission Clean Ganga (NMCG)–the implementing agency under this Authority–is now housed in the Ministry of Water Resources, River Development and Ganga Rejuvenation under the Government of India. The Mission Director is the chief executive of the NMCG.

At the state level in Uttar Pradesh, there is a state Project Management Group (PMG) chaired by the Chief Minister. It includes members from the State Ministries of Environment and Irrigation, the Uttar Pradesh Pollution Control Board and the state water commissions. The State PMG decides whom to select for work, and in most cases uses the Uttar Pradesh Jal Nigam (the state level sewage engineers) to execute wastewater project work.

The State PMG can outsource consultancy work and allocate projects to NGOs as well; although in all cases, it has allocated the wastewater engineering work to the Uttar Pradesh Jal Nigam. These layers of committee membership create a vast water bureaucracy at the state level in addition to the committee memberships and officers at the Central level. They are not independent regulators, monitors and compliance officers (which are needed) but contributors and benefactors of political and profitable decisions in the ongoing issuing of contracts, clearances and other approvals.

This is a big problem because any contract for sewerage work must pass through all these departments and boards, with money wasted on bids and approvals for specific projects. In addition there is no other implementing agency in Varanasi so if the UP Jal Nigam’s work is shoddy or even fraudulent, then the Ganga River and the whole city suffers without an alternative. This situation is well known to Banaras residents who will complain daily that funds meant to improve the sewerage system are simply eaten up by various agencies while wastewater is diverted into the sacred river without treatment.

In addition, the foreign donor agency, the Japan International Cooperation Agency or JICA, has been present in Varanasi for many years to advise and assist with capacity building and technological cooperation for the Ganga Action Plan. Apart from controlling the flow of funds, however, it appears that JICA has worked within the current lines of command and control, thereby helping to perpetuate rather than reform the system.

Infrastructure

So what is the current situation with the main wastewater drains? The main drains for the city are the Nagwa drain, located in the south and upstream of the main city, and Khirki nallah, located in the north downstream of the main bathing ghats. The Ganga flows northward at Banaras (see map). The Varuna River enters from the west and circles the outer part of the older sacred city complex before draining into the Ganga at the downstream or northern end. In the last year the Varuna River has turned into a wastewater pond upstream of the barrage recently built under the Puranapul Bridge that crosses the Varuna River. The Varuna river banks downstream of that barrage have also become the dumping grounds for all forms of solid waste and the entire landscape is hellish. One wonders how the communities in the vicinity can survive.

The existing wastewater management facilities include three sewage treatment plants, five sewage pumping stations along the ghats, and one main sewage pumping station at Konia. The Konia pumps are supposed to pump up to 80 million liters of sewage per day to the Dinapur treatment plant located in the trans-Varuna neighborhood of Dinapur village, if they work at full capacity. However they rarely do.

For instance, only one screw pump was working on the day of my visit, so that means it was running at 1/3 its capacity. This would also mean that the Dinapur treatment plant was receiving only 1/3 of the wastewater it is capable of treating, according to its nominal treatment capacity, and therefore it was running at 1/3 capacity. However to be exact one would have to know how many hours the one pump operates each day of the week and then the capacity factor can be calculated. For instance, if the pumping station runs at 1/3 capacity for only 6 of the 24 hours each day then the capacity factor would be 1/12 or about 8%.

If capacity factors of the pumping stations and treatment plants are taken into account in a Life Cycle Cost assessment then the cost per unit volume (ML) of treated sewage would sky rocket. The UP Jal Nigam does not keep a daily operational log with data like energy usage data, and thus there are no metrics, no measures, and no good management practices. This adds up to a lack of proper governance. Many monitoring committees have made visits to site facilities but have failed to correct the daily malfunctioning of the entire system. On my trip to videotape the Khirki wastewater drain in late June, I said to the boatman taking me, “So they release this water into Ganga ji at night and in early morning, right? Like chup ke?” He replied, “No Madam not chup ke. It is right there running wastewater all the time. Everyone can see it, and they are not even bothering to hide it!”

Below are current pictures of parts of the system that have been damaged, destroyed or poorly maintained. The map can be used to place these pictures in the city space.

Power

We have to think about wastewater problems in the context of public health, environmental health, electrical power supply and national and state priorities for power distribution. In the current scenario using existing technologies and scales (there are better options for technology and scale), a significant amount of energy is required to pump and treat wastewater using sewage pumping stations and the activated sludge treatment process. In India energy supplies are allocated to industrial and urban needs long before they are distributed to sewage treatment plants. Looking at the current energy scenario in India it is not hard to see that wastewater pumping and treatment require continuous power and are not sustainable in the context of the current power deficit. Biological secondary treatment using the Activated Sludge Process (ASP) uses a significant amount of electricity to operate aeration equipment and mixers. Another technology used in Kanpur, the Upflow Anaerobic Sludge Blanket (UASB), is also a capital and energy intensive process. With other demands high on the agenda, it is unlikely that precious power will be available to run all the existing and proposed sewage pumping stations and sewage treatment plants on a daily basis now and into the future if the existing technologies and scales continue to be used.

Take Away Points

If wastewater infrastructure is built, it is done with large government investments of public funds, sometimes with capital from international banks; there is little private equity to drive the process. Instead the costs of building (and also poorly building) these facilities are absorbed across a range of human services including public health, education, housing and infrastructure. The costs of operating and maintaining sewage pumping stations and treatment plants are also high and operation and maintenance of the facilities become a low priority after construction.

For instance, the sewage treatment plant laboratories are ill-equipped and this means that the UP Jal Nigam operators are unable to monitor, measure, and report operational and water quality data. Due to the absence of laboratory equipment, instruments and analytical capacity, they are not able to optimize the treatment process. Generally the functional components of the sewerage infrastructure – the sewage pumping stations and treatment plants – are overwhelmed by the dysfunctional components and by the enormous pollution load. In this way the functioning units in the system become important, not for effectively treating the waste but for projecting a façade of functional infrastructure, especially when site visits by monitoring agencies are underway. Yet the norm is that facilities are operated only periodically and usually below capacity, and the result is that untreated wastewater is passed through open drains to agricultural fields or rivers. During rains and the monsoon, wastewater combined with storm water flows directly into the Assi, Varuna, and Ganga Rivers.

This sacred city requires a competent participatory authority to master plan, design, select the right scales and technology, construct, operate and effectively maintain a comprehensive wastewater collection, treatment and reuse system. Its governance requires clearly defined norms of transparency, accountability and participation.

A competent authority should connect central, state and municipal levels and be accountable to the residents of the city not just through the municipal corporation and its elected officials, but also directly through norms of participatory governance. These governance reforms should include clearly defined norms of transparency, accountability and participation that pertain to the entire system and to each component part–the pumping stations, sewage and water treatment plants, sewers and associated facilities. A piecemeal approach with the Jal Nigam exclusively at the helm has not worked thus far and it has sunk crores of rupees into poorly operated and maintained infrastructure, even in the face of national and global attention and numerous judicial interventions to the cause of Ganga cleanup. A careful constitution of accountable engineering agencies, a welcoming approach in planning and implementation to citizen contributions, and a vigilant monitoring of operations and maintenance practices by concerned citizen groups can go a long way to reforming the system. There is no doubt that this cause runs deep in the hearts of every Banaras resident.

Riverfront Development in India: Cosmetic make up on deep wounds

September 17, 2014September 17, 2014 SANDRP7 Comments

There is a rush of riverfront development schemes in India. We have heard of Sabarmati Riverfront development being drummed many times, followed by the proposed rejuvenation of Ganga, supposedly on the lines of Sabarmati.

What does Riverfront Development entail? Is it River Restoration? Are the millions of rupees spent on Riverfront Development schemes justified? Will it help in saving our damaged rivers?

A cursory glance at the existing river restoration/ improvement/beautification schemes indicates that the discourse revolves mainly around recreational and commercial activities. It is more about real estate than river. Activities that are promoted on the riverfronts typically include promenades, boat trips, shopping, petty shops, restaurants, theme parks, walk ways and even parking lots in the encroached river bed.

Pioneering project in Riverfront Development was claimed to be the Sabarmati Riverfront Development project of Ahmedabad city which was supposed to be designed based on riverfronts of Thames in London and Seine in Paris. The project which began as an urban development project is lately being pushed as a role model for many urban rivers in India. This kind of riverfront development essentially changes the ecological and social scape of the river transforming it into an urban commercial space rather than a natural, social, cultural, ecological landscape. Is it wise to go for this kind of development on riverfronts? What does it do to the river ecosystem, its hydrological cycle? What does it do to the downstream of river? These questions need to be explored before accepting the current model of riverfront development as replicable or laudable.

Reclaim and beautify!

Most of the currently ongoing projects lay a heavy emphasis on beautification of rivers. Riverfronts are treated as extension of urban spaces and are often conceived as ‘vibrant’, ‘throbbing’ or ‘breathing’ spaces by the designers. Concrete Wall Embankments, reclamation of the riverine floodplains and commercialization of the reclaimed land are the innate components of these projects. Quick glimpse at various Riverfront Development Projects confirms this.

Sabarmati Riverfront Development Project

Sabarmati Riverfront Development Project of Ahmedabad city which is presented as a pioneer in urban transformation[1] has been proposed by Environmental Planning Collaborative (EPC), an Ahmedabad-based urban planning consultancy firm, in 1997 and envisaged to develop a stretch of 10.4 km of the banks on both sides of the river by creating concrete embankment walls on both banks with walkways. A Special Purpose Vehicle called the Sabarmati Riverfront Development Corporation Ltd. (SRFDCL) was formed in the same year for implementation of the project. The financial cost of the initiative was estimated to be in the range of around INR 11520 million[2]. Around two thirds of this amount has already been spent.

Construction of the project started in 2005. The project sought to develop the riverfront on either side of the Sabarmati for 10.4 kms by constructing embankments and roads, laying water supply lines and trunk sewers, building pumping stations, and developing gardens and promenades[3]. Mainstay of the project was the sale of riverfront property. Land along the 10.4 km stretch on both the banks was reclaimed by constructing retaining walls of height ranging from 4 to 6m[4]. 21% of the 185 ha of reclaimed land which was developed by concretizing the river bank[5] was sold to private developers for commercial purpose.[6] Activities hosted on this reclaimed land were recreational and commercial activities like restaurants, shops, waterfront settlements, gardens, walkways, amusement parks, golf course, water sports and some for public purpose like roads etc. The sale of reclaimed land created by the project is expected to cover the full cost of the project. Ahmedabad Municipal Corporation (AMC) claims that the after the project “river has added vibrancy to the urban landscape of Ahmadabad with its open spaces, walkways, well-designed gardens along with activities which contribute to economic growth.”[7]

Even though the project has been modeled as “best practice” by several financing institutions[8], it has also drawn severe criticism for poor rehabilitation of the displaced (rehabilitation happened only after High Court orders following a public interest petition) disrupting the nexus of shelter, livelihood and services of urban poor, lack of transparency in the execution and for tampering with the carrying capacity of the river. No Environment Impact Assessment of the project has been conducted nor any credible public consultation process held.

Sabarmati channel has been uniformly narrowed to 275 metres during the riverfront development project, when naturally average width of the channel was 382 metres and the narrowest cross-section was 330 metres[9]. In this attempt of “pinching the river”[10], the original character of the river is changed completely from seasonally flowing river to an impounded tank illegally taking water from Narmada Canal[11]. River banks have been treated as land that is wasted on which value could be created by reclaiming and not as seasonal ecological systems with floodplains as an integral part of its flows (Baviskar 2011). Seasonality of the river is destroyed and fauna and avi fauna on edges have been damaged. No thought has been given for protection, sustenance or enhancement of the riverine ecosystem. The water that is now impounded in this stretch is not even Sabarmati river water, but Narmada River Water, on which the city of Ahmedabad or Sabarmati has no right, it’s the water meant for drought prone areas of Kutch, Saurashtra and North Gujarat.

The River Sabarmati itself was a perennial river till the Dharoi Dam in the upstream stopped all water at least in non Monsoon months, making the river dry. The stretch flowing through Ahmedabad was carrying the mostly untreated sewage of Ahmedabad city and toxic effluents from the City and district industries.

In the name of Sabarmati River front development, no cleaning of the river has happened, the project has only transferred the water from both banks to the river downstream from Vasna barrage, which is situated downstream from the city. The Vasna barrage stops and stores the water released from Narmada Main Canal that crosses the river about 10.4 km upstream from the barrage. Thus this 10.4 km stretch of the river now holds the Narmada water and huge losses from the stretch are losses for the drought prone areas.

The reclaimed land and the narrowing of the channel have been tampering with the carrying capacity of the river. The project was stalled during August 2006 to March 2007 due to heavy floods[12]. Prior to the floods, the river’s maximum carrying capacity was calculated at 4.75 lakh cusecs on basis of the rainfall over last 100 years[13]. The floods however proved the calculation wrong. National Institute of Hydrology (NIH) and Indian Institute of Technology Roorkee (IITR) were asked to re-evaluate the project design, in the light of the river’s carrying capacity, and see whether the execution of the project would damage the river’s ecology[14]. Report by the NIH, Roorkee in 2007 said “the calculations did not take into account any simultaneous rainfall over the entire catchment area”[15]. This means that the carrying capacity was based only on the water flow from the Dharoi Dam (which is upstream of Ahmedabad City) and not from other places in the river’s catchment until Ahmedabad that also contribute to the volume of water in the Sabarmati. This report states that the riverfront development is “not a flood control scheme”, and that the municipal corporation will have to work out other measures to meet the impending challenge of floods.

The project is also heavily criticized for the poor rehabilitation of the evicted slum population. Large scale eviction was being carried out in an utmost non-transparent manner. A public interest litigation (PIL) was filed in the Gujarat High Court by Sabarmati Nagarik Adhikar Manch (SNAM) or Sabarmati Citizens Rights Forum, supported by several other non-governmental organisations (NGOs) to ensure that the rehabilitation plan was shared with them and to bring transparency to the process. According to the high court orders, at least 11,000 affected families were to be rehabilitated and resettled by AMC. Demolition drive went on without ensuring rehabilitation. Over 3,000 people have moved to a marshland in the outskirts of city with negligible compensation, little & infrequent access to drinking water and minimal sanitation facilities[16].

“The ecology of the river is being transformed to satisfy the commercial greed of a select few,” said Darshni Mahadevia of CEPT, expressing concerns about riverfront ‘beautification’[17].

The project that has converted the Sabarmati River into an urban space by reclaiming nearly 200 ha of land and has sustained by borrowing water from Narmada Canal today is claimed to be a role model for many riverfront development projects in the country. Should this model really be replicated? Many of the rivers like Yamuna, Ganga, Mithi, Brahmaputra etc. that are being ‘developed’, have had a flood history which is being ignored in the process. With having no regards to the hazards of floods, several riverfront projects are being pushed across the country by different government agencies.

The fact that even after a Riverfront Development Project, Water Quality of Sabarmati downstream the Vasna Barrage is extremely poor and the cosmetic treatment of flowing water stretch at Ahmedabad is actually water from Narmada, which was promised for the drought hit regions of Kutch and Saurashtra, highlights the contradictory and superficial nature of such Riverfront development schemes.

Yamuna Riverfront Development inspired from Sabarmati Model

Recently the newly elected BJP led Central Government sent a team of bureaucrats to Gujarat to study the feasibility of replicating the successful model of the Sabarmati Riverfront Development Project for cleaning the Yamuna[18]. Despite the concerns about flooding of Yamuna, the team is exploring ways of replicating Sabarmati Model. In 2009, the Sheila Dikshit administration was also planning channelizing the Yamuna and putting up a waterfront like Paris and London with recreational facilities, parking lots and promenades etc[19].

Reclamation of the floodplains to create a concrete riverfront, like in Ahmedabad, could be ecologically unsound and even dangerous for Delhi that is already extremely vulnerable to floods[20]. The sediment load in Yamuna is very high. The non-channelized river rises by over four metres during peak monsoon flooding[21]. Risk of flooding will increase multifold for a channelized river. The Inter-governmental Panel on Climate Change last year put Delhi among three world cities at high risk of floods. Tokyo and Shanghai are the two other cities.

An expert committee appointed by the Ministry of Environment & Forests (MoEF) to examine the Yamuna River Front Development Scheme of the Delhi Development Authority (DDA) recommended that DDA should scrap its ambitious plan for developing recreational facilities, parking lots and promenades. [22] The committee was formed following order from National Green Tribunal which was drawn in response to a petition filed by activists and Yamuna Jiye Abhiyaan convener Manoj Misra.[23] The committee pointed out that recreational spots located in active floodplain areas would kill the river and cause floods in the city. About the Sabarmati Model Being followed, CR Babu, Chair of the committee said: “There is no Sabarmati river. It’s stagnant water with concrete walls on two sides. The floodplains have been concretized to make pathways and real estate projects. It cannot be replicated for our Yamuna”.

The committee report says the Yamuna Riverfront Development scheme will reduce the river’s flood-carrying capacity and increase flooding and pollution and it recommended a ban on developmental activity in the river’s Zone ‘O’ and its active floodplains on the Uttar Pradesh side. It also said that a 52-km stretch of the Yamuna in Delhi and Uttar Pradesh be declared a ‘conservation zone’ as restoring the river’s ecological functions is heavily dependent on the environmental flow through this stretch, particularly in the lean season.

Manoj Misra of Yamuna Jiye Abhiyan, dismisses the Sabarmati solution saying “We cannot call it a Sabarmati model… It’s like a mirage created for a brief stretch. Let’s be clear about it. If the Delhi bureaucrats have gone there to learn from the Gujarat model, it’s up to them to figure out if it can be implemented. I cannot call the Sabarmati project a river rejuvenation project – it’s more of a real estate project… That is not advisable for Delhi.” [24]

Another important aspect which does not feature at all during the talks of Yamuna Riverfront Development is the massive displacement that will take place. Over a dozen unauthorised colonies are located on the riverbed. These colonies which have been in existence for over 40 years will have to be uprooted which again may lead to Sabarmati like situation where urban poor are brushed aside to serve interests of real estate developers and urban middle class.[25]

City of Noida on the other hand has decided to go ahead with the Rs 200 crore Yamuna Riverfront Development Project that Greater Noida Authority (GNA) has been planning[26]. The project involves developing recreational facilities like parks, Yoga centres, picnic spots and sports centres, polo grounds, golf course etc. on Hindon and Yamuna floodplains. Officials from GNA claim that these facilities will be for recreational purpose and will be developed without disrupting the natural flow of Yamuna. Here again the project has nothing to do with sustaining, cleaning, rejuvenation of the river.

Ganga cannot be ‘developed’ as Sabarmati

Prime Minister Narendra Modi made a promise during his election campaign in Varanasi to clean up Ganga.[27] The National Ganga River Basin Authority (NGRBA) was shifted from the environment ministry to the water resources ministry.[28] New name for the Ministry of Water Resources is Ministry of Water Resources, River Development and Ganga Rejuvenation. Uma Bharati was assigned with this specially created ministry for cleaning Ganga by the PM. “If Sabarmati can be cleaned, all other rivers can also be made better.” print media has quoted Uma Bharati.[29] Ms Uma Bharati seems to have no idea that Sabarmati has NOT been cleaned, the Sabarmati project just transferred the polluted water downstream of the 10.4 km stretch. Can Sabarmati Model be replicated at Ganga? Even if it is replicated, will it help the cause or river or river rejuvenation? The answer is clearly a BIG NO. A number of apprehensions have been raised in this regard. “The so-called Sabarmati model won’t work for the Ganga. The Sabarmati has neither been cleaned nor rejuvenated,” Openindia News quotes Himanshu Thakkar, environmentalist and coordinator of SANDRP[30]. He further points out that
Sabarmati Model survives on water from Narmada canal in the stretch of 10.4 km which flows through the Ahmedabad city. This is not possible in case of Ganga.

Priority for the river rejuvenation is restoring its water quality, freshwater flow and not riverbank beautification. More than Rs. 5,000 crore (some estimates this figure to be over Rs 20 000 crores) has been spent on cleaning the Ganga in the past 28 years. The Ganga Action Plan was launched in 1986 and was in 1994 extended to the Yamuna, Gomti and other tributaries of the Ganga. The second phase of the Ganga Action Plan was launched in 2000 and NGRBA was created in 2009.[31] The plan however has not achieved what it set out to achieve. Water quality for Ganga River has been declining and is unfit even for irrigation or bathing. Potable use is out of question. The count of harmful organisms, including hazardous faecal bacteria, at many locations is more than 100 times the limit set by the government. The water’s biochemical oxygen content, which is vital for the survival of aquatic wildlife, has dipped drastically.[32] Any “cosmetic treatments”[33] will not work for Ganga, like they have not worked for Sabarmati.

Several Riverfront Development Projects springing up across nation

While there are experts opposing replication of Sabarmati Riverfront Project on Ganga and Yamuna River, there are several other riverfront projects which are inspired by the Sabarmati Project and which are being pushed without any kind of studies or impact assessment. Their possible impacts on the riverine ecology, flood patterns, downstream areas etc. are going unchecked.

Brahmaputra Riverfront Development Project: Another “multi-dimensional environment improvement and urban rejuvenation project” that is set to come up with plans for reclaimed river banks is on Brahmaputra River in Guwahati[34]. While on one hand the city is struggling to cope up with the flood prone nature of the Brahmaputra River, State Government of Assam plans to take up an ambitious project to develop the city riverfront named ‘Brahmaputra Riverfront Development Project’ under the Assam Infrastructure Financing Authority. The riverfront project will be implemented by the Guwahati Metropolitan Development Authority (GMDA) in phases[35]. Foundation of the beautification project was laid by the Chief Minister Tarun Gogoi in February 2013. The project plans to achieve maximum possible reclamation[36].While the plan talks of revitalization of the river ecology and Strengthening of riverbanks through soil bio engineering it has several urban features on its agenda like promenade, Ghats, Plazas and Parks; buildings, conference facilities, Parking lots, ferry terminals, Bus and para transport stops, Urban utilities and drainage, Improved infrastructure for floating restaurants, Public amenities; Dhobi Ghats, etc.[37]

Will such a huge real estate development leave any room for river or its revitalization?

Tendency to flood is an important feature of River Brahmaputra. The river also has one of the highest sediment loads in the world. Every year during the successive floods, most of the areas in the valley of Assam remain submerged for a considerable numbers of days causing wide spread damages. In a phenomenon as recent as June 27, 2014 Guwahati experienced heavy downpour for 15 hours, setting off flash floods[38]. Half of the city was submerged under flood water. The authorities blamed illegal encroachments on watersheds across the state capital for the flash floods, which had choked the natural outlets for the gushing water. National Institute of Hydrology (NIH), Roorkee; upon being requested by the GMDA; is carrying out a study which includes river shifting analysis for studying stability of the river banks, flow variations to determine the perennial water depth, estimate of floods of various return periods for design of river embankments, estimate of water surface profiles employing hydro-dynamic river flow model and design parameters for river embankments[39]. The Bramhaputra Riverfront Development Project however has been inaugurated even before the requisite studies have been completed.

Gomti Riverfront Development Project in Lucknow: The project by the Lucknow Development Authority is based on the Sabarmati Riverfront Model. It plans to “beautify” Gomti River between Gomti Barrage and Bridge on Bye-pass road connecting Lucknow-Hardoi road and Lucknow-Sitapur road, a length of about 15 Km. According to the Technical Bid Document released by the Lucknow Development Authority, the Riverfront Project has no component of water treatment or river restoration, but is a landscape-based development project, which will also look at “reclaiming” the river banks for activities like shops, entertainment area, promenades, etc. The inspiration for the project swings from Thames Rivefront in London, to Sabarmati in Gujarat, depending on the political party in power.[40]

In all this discussion, there is no mention of maintaining adequate flow in Gomti, treating sewage, conserving its floodplains, or any other ecological angles.

River Improvement and Restoration are also about real estate!

For many government agencies, ironically, not just river beautification, but the idea of river improvement and restoration is also about channelizing rivers and providing recreational facilities.

Pune Rivefront Project: Pune Municipal Corporation, the Pune city also known for chronically polluting Mula and Mutha rivers that flow through the heart of the city, has sanctioned a River Improvement Project, under the aegis of JNNURM (Jawaharlal Nehru National Urban Renewal Mission). The Project envisages channelizing the river, introducing barrages to maintain water levels, development of riparian zone as entertainment and shopping groups, even Parking lots, introducing navigation in the river etc. There are several issues with this “improvement” project. Firstly, it is not planned according to the once in a hundred years flood in Pune, it plans to constrict the river further, thus encroaching the riverbed. Creation of stagnant pools through barrages will result in backwater effect on the many nallahs that join the river. These Nallahs routinely flood in rainy season and additional backwater in these nallahs will worsen the situation further. The project does not say a word about treating water quality, but envisages to build drainage lines inside the riverbed and carry the sewage out of Pune city limits. This hardly qualifies as river rejuvenation or restoration. A case has been filed against this project in National Green Tribunal.

Goda Park (Godavari Riverfront Project) in Nashik, Maharashtra: Godavari emerging from the Brahmagiri Hills in Nashik is famed not only for being one of the longest rivers in India, but also because Kumbh Mela is held on its banks every 12 years in Nashik. Nashik and Trimbakeshwar have had no dearth of funding for cleaning Godavari. They have received funds from the National River Conservation Directorate as well as JNNURM. Despite this, Godavari is extremely filthy in Nashik. Ignoring the pressing issues of water quality, Nashik Municipal Corporation and a specific political party have been hankering after beatification of Godavari’s banks. In fact, the project has been handed over to Reliance Foundation by the Nashik Municipal Corporation[41] without any public consultations or discussions. As per reports, the components of this 13.5 kms long project will be laser shows, musical fountains, rope-way, multi-purpose meeting hall, garden, water sports, canteen, etc.[42]

In the meantime, there are several court orders against Nashik Municipal Corporation pending about severe water pollution in the River including Ram Kund where holy dip on Kumbh Mela is supposed to be taken.

Mithi Riverfront Development: Stretch of 18 km of Mithi River flows through city of Mumbai. Course of Mithi has been modified throughout the city to host range of activities.[43] On 26 July 2005, the river flooded some of the most densely populated areas claiming nearly 1000 lives[44].

After these catastrophic floods, the Municipal Corporation of Greater Mumbai (MCGM) and Mumbai Metropolitan Region Development Authority (MMRDA) made a plan to “restore” the river. BMC and MMRDA’s definition of restoration involves desilting, beautification and building of a retaining wall. Stretch of 4.5 km of the total six km stretch of the river that falls within MMRDA’s jurisdiction is covered with mangroves. MMRDA has planned to beautify the stretch of remaining 1.5 km (10 Ha) which lies right amidst mangroves by developing a promenade. MMRDA plans developing this project on a PPP (Public Private Partnership) basis. Interestingly, the Mukesh Ambani-led Reliance Foundation and Standard Chartered bank have been selected for this project.[45]

As per the Coastal Zone Management Plan (CZMP) of the area, the proposed Mithi Riverfront Development Project falls in Coastal Regulation Zone (CRZ) II and III. The proposal was presented to CRZ authority in its 82^nd meeting on 10^th June, 2013[46]. CRZ authority has not allowed any reclamation or construction activities in this stretch. For Widening, lengthening & reconstruction of the existing bridge CRZ has referred the proposal to MoEF and asked MMRDA to take prior permission of High Court if the proposal involves destruction of mangroves[47].

Observer Research Foundation, a private, not for profit organization (funded by Reliance India[48]) from Mumbai has come up with a study that recommends a 21-point programme for reclaiming the Mithi, envisaging a single and unbroken river-park corridor spanning across the entire 18-km length of the Mithi with dedicated bicycle tracks, gardens, amphitheatres, sports and recreation.[49]

Riverfront Development is NOT River Restoration

As is evident, the riverfront projects discussed above are essentially river bank beautification & Real Estate Development projects and not helping restoration of the river. The projects aim at comodifying rivers to develop urban scapes. Such riverfront development changes the essential character of the river. Stream channelization and alteration of shoreline disconnects the river stretch from adjacent ecosystems and leads to risks of habitat degradation, changes in the flow regime and siltation[50].

While the water of the rivers flows in the natural landscapes, there are many processes that are happening. Sediments are carried, fertile land is created along the banks, river channel is widened, flooding, deposition of sediments during flooding, cleansing of river etc.[51] However the urban rivers are alienated from this natural landscape to such an extent that the rivers are reduced to merely nallas carrying city’s sewage and filth.

Flow, connectivity and flood are fundamental characteristics of rivers and rivers need space for that. If these are violated the river water spreads uncontrolled through the habitation causing catastrophic events like Mithi Flooding.

Creating more room for rivers

While Indian cities are busy replicating Riverfronts of Thames and Seine, there are some remarkable projects going on in some other countries which actually talk of giving more room to the rivers during floods. They are trying to restore the river and not beautify, concretize, channelise or encroach on it.

In the Netherlands, such an integrated approach has been adopted for ‘Room for the River Program’[52]. The program is currently being implemented in the Dutch Rhine River Basin of the country.

The programme started in 2006 is scheduled to be completed by 2015. The objectives of the programme are improving safety against flooding of riverine areas of Rivers Rhine and Meuse by increasing the discharge capacity and improving of spatial quality of the riverine area.

At 39 locations, measures will be taken to give the river space to flood safely through flood bypasses, excavation of flood plains, dike relocation and lowering of groynes etc. Moreover, the measures will be designed in such a way that they improve the quality of the immediate surroundings.

While Room for the River programme focuses on flood management in sustainable way, Yolo Bypass is another unique initiative aimed at keeping intact the benefits to the ecosystem without causing a negative impact on water supply[53]. The Yolo Bypass is a flood bypass in the Sacramento Valley located in Yolo and Solano Counties of California State in USA. The primary function of the bypass is flood damage reduction. It is a designated floodway that encompasses 60,000 acres in eastern Yolo County between the cities of Davis and Sacramento. All the properties within the bypass are subject to a flood easement that allows the state to flood the land for public safety and ecological benefit.

Conclusion

Riverfront of Thames in London and Seine in Paris are often cited as successful models of riverfront development in India. However, the ecological as well as social setting of Indian rivers and the challenges that we face are significantly different from these foreign models. A Blind replication will only be wastage of public funds and degradation of the rivers further. Riverfront development projects across the country seem to be alienated from the river, and talk only about its urban banks, trying to achieve cosmetic changes on deeper wounds by encroachment and real estate development on the belly of the rivers. The need of the hour is river rejuvenation and not river FRONT development. Let us hope that we see central place for rivers in all these projects. Moreover, there is neither any social or environmental impact assessment, nor any regulation or democratic participatory decision making process. Such projects will only be at the cost of the poor, the environment, future generation and to short term benefits of real estate developers and a section of urban middle class.

[43] The Mumbai airport has its domestic and international terminals, and its cargo complex along the Mithi River. There are five major railway stations along the Mithi River including Mahim and Bandra on the western line andSion, Chunnabhatti and Kurla on the central line. The upcoming V ersova-Andheri-Ghatkopar corridor of the Mumbai Metro project that also crosses over the Mithi River has two stations planned along the Mithi River at Marol and Saki Naka. There are also several bus stops located close to the river all along its banks.

Dams, Fish and Fishing Communities of the Ganga: Glimpses of the Gangetic Fisheries Primer

August 30, 2014August 30, 2014 SANDRP6 Comments

Some highlights from SANDRP’s latest Publication on Riverine Fisheries of the Ganga

The government is discussing Ganga not only as ‘Ganga Mata’, but also as a ‘navigational corridor’ with plans to build barrages after every 100 kilometers with funding from World Bank. At her origin, hundreds of hydropower dams are changing the ecological character of the Ganga. However, as a rich ecosystem, the Ganga also supports about 10-13 million riverine fisherfolk and about 300 freshwater fish species! Riverine fisheries have been a blind spot in Independent India, despite the fact that they provide nutritional and livelihood security to millions of people.In the post independence water management discourse, river has been equated to water and water to irrigation, water supply, and hydro power. The profound impacts of irrigation, water supply and hydropower dams on sectors like riverine fisheries have been entirely ignored.

Nachiket Kelkar looks at the status of riverine fisheries and fisher communities in the Gangetic Basin of India and highlights the devastating impacts of dams, barrages and water abstractions on this. Nachiket’s study on Gangetic Fisheries is based on long term engagement with fisher communities in the basin as well as robust scientific studies.

SANDRP has published this work in the form of a Primer which will soon be available online. What follows are some glimpses from the Primer. Please write to us if you are interested in receiving a full soft copy of the Primer.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Riverine fisheries of the Gangetic basin support one of the largest fishing populations of the world. However, its fish resources are rapidly declining due to large dams, barrages and hydropower projects, severely altered river flows, fragmentation of hydrological connectivity between rivers and wetlands, alarming levels of pollution, riverfront encroachment, rampant sand mining and unregulated overexploitation of fish resources.

Across its range, the fisheries show indications of economic unviability and ecological collapse, with violent social conflicts as an outcome of the contest over scarce and declining resources as well as politics and access. A major factor behind the serious fisheries-related problems is severe alteration of river flow volume and seasonal dynamics by large dams, barrages and hydropower projects. The state of river fisheries directly indicates the declining biophysical, ecological and social integrity of the river basin. The existing in-river fisheries contribute merely about 10% of the overall inland fish production. Even this production is highly unsustainable today and has all the indicators of serious levels of overfishing. For instance, river fisheries in Bihar now even glean small-sized fish fry for markets in northern West Bengal (Siliguri) and Assam, where eating small fish is a delicacy (F.pers.comm).

To understand the situation in Gangetic Basin clearly, a detailed, large-scale interview survey was conducted by the author in 2012 across 372 fishers in 59 fisher groups spread over 17 rivers in 5 north Indian states. The survey objective was to document perceptions of traditional fishing communities about issues and problems in fishing in the Gangetic basin. Of the respondents, c. 90% singled out “large dams and poor river flows” as the main causes for a near-total decline in fisheries and fish resources over the past 4 decades. About 90% people mentioned low water availability and stoppage of fish migratory routes by large dams as the main cause for fish declines. Almost 45% (from eastern and northern UP, and Bihar) singled out the Farakka barrage as the main problem.

The Canvas of Gangetic River Fisheries
The Ganga River, from her headwaters to the delta, along with hundreds of her tributaries drains an area of approx. 0.9_1 million km2 across northern and eastern India, flowing through 10 states in India and also in Nepal and Bangladesh. These rivers form one of the largest alluvial mega-fan regions of the world, and deliver huge quantities of sediment from the Himalayas to the northern Indian plains and to the Bay of Bengal in the Indian Ocean. The Gangetic floodplains shape not only landforms but also complex human cultures that attempt to stabilize themselves and adapt to the constantly changing riverine forces. Biodiversity, hydrology, geomorphology and social dynamics influence each other through constant interaction and multiple feedback mechanisms.

The major rivers of the Gangetic Basin (Based on ‘hydro1k-rivers-Asia.dbf’).

The dynamic balance of these factors triggers opportunities for spawning, reproduction, population dynamics and viability, migration and movement of freshwater species, including fishes, river dolphins, otters, crocodilians, turtles, invertebrates as well as terrestrial biodiversity.

In floodplain rivers, as floodwaters recede post-monsoon, fishers record the highest catches in October and November, as large post-breeding and migrating adult fishes (e.g. major carps, clupeids, mullet) become catchable. Winters, from December to early February, generally record low catches because many fish show slowed behavior and limited movement. But in spring fisheries of minor carps and catfishes record high production. With water levels reducing, fishes become more concentrated in specific river habitats like deep pools, where they are easy to fish. Summer fish catch biomass is also reasonably good due to the overall low water availability.

In the Gangetic basin, fisheries are practiced in a range of diverse freshwater habitats including natural and man-made, lentic (stagnant water) and lotic (flowing water) ecosystems. Natural freshwater areas include large floodplain rivers, non-perennial rivers, perennial and seasonal streams, cold-water rivers and streams, glacial lakes, estuaries, tidal rivers, floodplain wetlands, oxbow lakes, grassland swamps and marshes. Manmade habitats include dug or built-up wetlands, ponds, man-made reservoirs, dam reservoirs and canals. To the fisher, flow velocity, depth profile, substrate type, vegetation structure, current patterns and habitat stability are key indicators for fishing effort allocation and logistical decisions.

Fish Diversity in the Gangetic Basin
The overall species pool of the Gangetic fish assemblage is estimated at around 300 species (53+ families, 150+ genera; 250 species). The floodplain fisheries are dominated by major and minor carps (Cyprinidae), catfishes (Siluriformes: 6-7 families), Clupeidae, Notopteridae and a mix of many other families. Major carps and the Clupeid fish, Hilsa (Tenualosa ilisha) and some large catfishes form the most valued catches across most parts of the Gangetic floodplains.
Major carps, the most preferred freshwater food fishes, include species like Catla, Rohu, Mrigal, Mahseer etc. exhibit potamodromous (along freshwater upstream-downstream gradients) migration. Though these fishes have suffered serious declines due to overfishing, pollution and dams, they have been mass-produced through artificial rearing in pond aquaculture. Farmed large carps form the major proportion of fish eaten anywhere in India today. In wild fisheries, catfishes come lower in the preference order, but with the decline of carps, medium and small catfishes have become the main fishing targets. Further, as most catfishes are sedentary and do not show long-distance movements, the fisheries have completely switched from carp- to catfish-targeting fisheries. Other deep-bodied, highly sought after fishes include the Chitala and Notopterus, or the featherfishes, and mullet.

Various fish species in Ganga Basin. Refer to the Primer for more information.

The estuarine fishery in the Hooghly and Sunderbans tidal rivers in West Bengal is dominated by shellfish (prawns, mud crabs and shrimp), Clupeidae and Engraulidae, Sciaenidae, catfishes of the Ariidae and a far more diverse set of families compared to truly inland fisheries. Other important components of the commercial fisheries include 5-6 species of shellfishes (mainly prawn and shrimp).

Coldwater fisheries specialize on large-bodied, rapids-loving potamodromous migrant fishes such as Mahseer and Snow Trout. These fishes are of high commercial importance and are in high demand by professional sport fishers and anglers, apart from being highly prized as food locally. Mahseer in particular, have recently led to the opening of new markets of luxury wildlife tourism that is based on angling and recreation in the Western Himalaya.

Dam reservoir fisheries are almost entirely based on managed stocking and breeding of commercial fishes in hatcheries, of major carps Catla, Rohu and Mrigal, catfishes like Pangasiodon, and minor catfishes. The state of river fisheries in the Gangetic basin has been affected over the last few decades by several threats described in the next section.

Dams and Riverine Fisheries in India Fisheries across India have been severely affected by dams, flow regulation and associated human impacts, which have substantially altered ecological requirements of fisheries and biodiversity together. If one clinically investigated the fisheries’ decline, they would find it to coincide with the period of maximum dam building (1970s-80s) in India. Most commercially valuable fish species, especially major carps and Hilsa, have shown population-level collapse and even commercial extinction over large inland waters. Reduction in harvested fish size-class distributions, a classical indicator of overexploitation by fisheries, points to poor fish recruitment and adult survival, which may be further brought down by flow regulation by dams. Dams have acted as the major factor of disruption by blocking migratory routes of upriver or estuarine spawning fishes such as Hilsa and Anguilla eels. Dams have also caused loss of genetic connectivity between fish populations, most notably seen in major carp stocks. Erratic water releases, nutrient and sediment trapping behind dams and barrages, failure of breeding in carp and catfish species due to siltation, erosion, poor water availability, modified thermal regimes required for breeding (increase in temperatures due to low river depth/flow), and exceptional levels of hazardous pollution (again, magnified due to the poor flows reducing dilution capacity of river water), are other fallouts that adversely affect fisheries. The fact that there is just not enough water in the river must form the bottom line of any causal investigation of riverine fisheries. Lack of appropriate policy measures and pollution receive dominant mention as threats to fisheries by government research agencies, but they are mere outcomes of much larger shifted baselines because of dams. Dams, barrages and hydropower projects through flow regulation have increased uncertainty about fishing and driven fishing to desperate levels: fishers often resort to destructive practices, or even worse, exit the fishery altogether. Such exit does not solve the problem of existing fisher folk: water is critical to sustaining not just fisheries but the river and the people dependent on it. Detailed understanding of the lives of fishing communities of the Ganges is therefore critical.

Fisher communities in Ganga: Around 10-13 million people in the Gangetic floodplains are estimated to be dependent on fish resources for their livelihoods, directly or indirectly. However, accurate estimates of active traditional and non-traditional fisher populations are still wanting. It is important for any discussion on fishing communities to clearly separate traditional fishing communities from ‘non-traditional fishers’, who may be practically from any other local community and with the possession of other livelihood options, but also opportunistic fishing, due to unrestricted access to imported nets and gear available in markets to anyone. Traditional fishing communities were always the craftsmen of their own nets and gear, and also possess remarkable ecological knowledge about rivers, fish and biodiversity, their breeding biology, ecology, seasonality, and distribution. Of course, with the degradation of fisheries throughout the Gangetic plains, the traditional knowledge and practices of fishing are eroding fast. Hence such knowledge needs to be documented well, especially from old fishers with whom it still persists, to identify historical baselines of river fisheries with a different, past ecological reference (pers.obs.; F.pers.comm).
Traditional fishing communities today form a highly marginalized, politically unorganized and socio-economically impoverished people. Caste discriminations and political history form the chief reasons for their poverty and subjugation over centuries of fishworking. But the present condition of rivers does not seem to offer hope to any improvement in their economic position unless and until there is collective voicing of their concerns, especially against large-scale water engineering projects that threaten their livelihoods.

Their livelihoods, one may argue, confined them to the river’s water, albeit the fact that they never owned the waters legally. However, they always have stated cultural claims of temporally confined territory, following their foraging preferences and site usage. But depending on the nature of the river’s hydrological dynamics, there may be variable maintenance of fixed ‘territories’ by fishers adopting a roving mode of fishing, and neither legal nor cultural claims can be reconciled to a level that the conflicting parties can reach mutually. With regards to their economic viability and status, a large proportion of the traditional fishworkers fall Below the Poverty Line (BPL), and are recorded as Economically Backward Castes, and also have been assigned the status of Scheduled Castes. Annual incomes from fishing alone, according to the few estimates available, range from INR 25,000/- to INR 50,000/- (pers.obs., F.pers.comm.).

Large dams, flow regulation and Gangetic basin fisheries : The singular key problem of fisheries today is that it lacks water in the dry-season, because of flow regulation by dams, barrages and hydropower projects. More water flow releases are needed for the protection of riverine fisheries in the Gangetic basin. Widespread river habitat degradation, industrial, agricultural and domestic pollution, altered flows and modification of sediment and nutrient fluxes by dam projects, and resource overexploitation (by fisheries, agriculture or industry) have had major consequences for the unique biodiversity and fisheries of floodplain rivers across Asia. Obstruction and fragmentation of river flow, habitat destruction, accelerated erosion and siltation, long-distance water diversions (involving huge amount of transmission losses and waste) and poor flow releases are the major direct threats of dam-canal systems in the Gangetic plains.

Flow volume problems: Lower-than-minimum flows have been consistently recorded across the Ganga, Yamuna, Chambal, Kosi, Sone, Ken, Betwa, Ghaghra and Gandak rivers. Along with these large rivers, almost all others (Rapti, Baghmati, Mahananda, Teesta, Kamla, Burhi Gandak, Punpun, Gomti and others) have been highly regulated64,69. The reduction of freshwater discharge reaching the Sunderbans because of the Farakka barrage has led to high degree saline ingress throughout the estuary, causing die-offs of considerably large tracts of mangroves and aquatic vegetation, as well as severe losses to the upstream fishery. Downstream, fishing practices suited to brackish and fresh waters now have to adapt to saline intrusion into the estuary’s waters. Globally, fragmentation and flow regulation have caused the most severe impacts through drastic alterations to riverine biota and ecology. Low flows and fragmented connectivity of river channels lead inevitably to fish population declines and breeding failure. Over time, dams have probably led to genetic isolation of fish populations as well as river dolphin / crocodile populations, destruction of fish breeding habitats and spawning triggers and loss of valuable wild fish germplasm. These losses are so large in their ecological value and opportunity costs that they cannot be recovered with artificial fish culture techniques or hatcheries.

Aggravation of pollution effects: The Ganges basin is one of the most polluted large river basins in Asia, especially with regards to domestic sewage and agricultural runoff. Poor flows reduce the dilution and self-purification capacity of river water to reduce concentration of pollutants and local impacts on fishes. . Agricultural fertilizers (organophosphates, organochlorines, nitrates etc.), heavy metal pollution from industrial effluents, thermal power plants, oil refineries, distilleries and tanneries, and nitrogen-rich sewage, waste-water and non-biodegradable substances such as plastics, mercury, radioactive compounds and hospital wastes can cause fish kills or even worse, lead to high levels of toxicity in tissues. Pollution problems are especially acute in highly regulated river reaches, especially around Delhi (Yamuna River), and the Gomti at Lucknow, Yamuna until Panchnada in UP and Ganga River at Kanpur, Allahabad, Varanasi, Patna, Barauni, Bhagalpur and Farakka.

Siltation in dam reservoirs and barrage gates: Excessive siltation in the Ghaghra barrage has led to, as per local fishers, breeding failure in Labeo angra (Ghewri), a preferred spring-fisheries target in the region. The fishers claimed that over the past 5 years they have not captured a single fish with eggs inside it, and also added that catches have plummeted heavily (F.pers.comm). Siltation of gravel/sediment in reservoir or storage zones is a problem of huge magnitude for fisheries, especially through breeding failure. Accumulated silt in reservoirs is estimated to be so high (in tens of meters height) that it cannot even be easily flushed out, and leads to nearly 60-90% reductions in sediment fluxes of rivers in monsoon and non-monsooon seasons. Siltation adds to obstruction of flow release through barrage gates. In the Farakka barrage, sediment load accumulation is leading to breakage of gates every year, adding to maintenance costs.

Habitat destruction and alteration of erosion-deposition dynamics: Soil erosion by erratic and sudden releases before floods can potentially lead to alteration and destruction of fish breeding habitats and stock depression. Changes in depth and flow velocity lead to fish not being able to receive natural physiological cues for movement and spawning that are otherwise provided by variability in discharge. Flow alteration also alters hydrological connectivity and sediment transport with wetlands and confluence channels during flooding. As a result these productive breeding habitats often become unavailable for catfishes and carps. These factors together become a problem for pre-settlement fish juveniles and recruits, which move into the main channels.

Threats to cold-water and foothills fisheries from Hydropower Dams: Overall, despite their projected low impact situation, hydropower projects can have serious large-scale effects on mountain streams as well as rivers downstream. Globally, despite mitigation measures in hydropower constructions, fish migration and development have largely been deemed as failures. In India, hydropower projects, especially run-of-river projects in higher altitudes, often have disastrous effects on natural thermal regimes, cause sediment blockages and perturb natural flow variability at diurnal timescales through releases varying across several orders of magnitude. These changes severely affect not just breeding and migration in higher-altitude cold-water fisheries of snow trout and Mahseer in Himachal, Sikkim and Uttarakhand, but also downstream fisheries of catfish and carps in the foothills and plains due to altered flows. Their cumulative downstream impact can also potentially risk fisheries-based uses of river water without being exposed to the risk of sudden flow releases every day.

Globally, through extreme perturbation of natural flow dynamics, dams have homogenized and altered many crucial river-floodplain processes, and have had disastrous impacts on biodiversity and fisheries. There is an urgent need to ensure ecologically necessary, adequate and natural flow regimes in all rivers of the Gangetic basin. The current water scarcity is so severe that projects such as river interlinking, apart from their ridiculous proposed costs, are simply impossible to conceive of, water itself being the limitation. There is no doubt that further water developments will prove disastrous for a whole section of people and their livelihoods, and must be scrapped. Rivers that need urgent attention in this respect are the Chambal, Yamuna, Ken, Betwa, Alaknanda, Bhagirathi, Mandakini, Sone, Damodar, the Ganges at Farakka and Allahabad, Sharada, Ghaghra and all other rivers especially in Uttar Pradesh, Uttarakhand, Madhya Pradesh and Bihar0. Run-of-river hydropower projects, flow diversions and links, pumped irrigation, embankments, agricultural intensification, groundwater depletion and sand mining are highly destructive threats that will affect not just fisheries but the whole social fabric of river users in the near future.

Despite the demonstrated folly of not allowing rivers to flow from headwaters to estuaries and deltas, engineers, technocrats and politicians talk of “rivers flowing wastefully into the sea”. This statement would imply that the thousands of species and millions of fisher livelihoods that need flowing water in rivers are of no value to the state policy on water resource development. Such statements are ignoring important societal needs and hence are evidently irresponsible.

No post dam-construction compensation schemes exist for fishers, who may lose their entire livelihood because of flow-regulation and loss of hydrological connectivity due to dams. Downstream fisher populations must be ideally compensated for the lost fishing catch and livelihood opportunity, but in general there has been scant attention towards the communities’ livelihoods (F.pers.comm). Downstream water allocations through on-ground consultations with fisher communities are urgently needed (F.pers.comm). In India, water resources development is so strongly irrigation-focused (and now strongly focused on industry and hydropower), that, in comparison, riverine fisheries are not even acknowledged as legitimate and in need of conservation and livelihood protection. These biases mean that only pond aquaculture receives any attention. If river conservation and development groups can actively work with fishing communities in order to develop an informed and aware constituency or interest group, fishers will gain political voice in making negotiations about water availability in river basins.

Fisheries incur ‘colossal losses’ every season due to irregularities in dam operations, and always fall severely short of demand. But now, through the boom of artificially managed pond aquaculture and wetland fishing especially in Andhra Pradesh and West Bengal, the nature of supply itself has radically changedThis boom has contributed to India becoming one of the largest producers of inland freshwater fish in the world. But such ranking hides a lot of miserable facts about river degradation. Although net production shows increases, the collapse of river fisheries that still support millions of poor people who don’t get access to aquaculture, get totally ignored under such swamping. This is why farmed fish in fish hatcheries can barely replace riverine fisheries despite the fact that they have cornered the attention of fisheries development.

The failure of river fisheries has led to large-scale outmigration for labour from the Indo-Gangetic plains (F.pers.comm.). This might be a significant contributor to the magnitude of labour-related migrations from the Gangetic plains, which has been a rising exodus. Today, fisher folk from Uttar Pradesh, Bihar and Bengal provide a large proportion (20-40%) of construction and manual labor force across India (F.pers.comm). Others who stay behind have to take to menial jobs such as rickshaw-pullers or servants (F.pers.comm; pers.obs). Some are forced to take to crime to be able to feed themselves and their families. These factors can weaken the social resilience of production systems and create poverty, disparity and community breakdown. It has been argued that ethnic conflicts between local Indian populations and illegally immigrated Bangladeshi refugees are linked to poor water releases from the Farakka barrage in West Bengal, to downstream floodplain reaches in Bangladesh.

Mitigation measures like Fish ladders and hatcheries
There is little existing research on the construction design, functioning and efficiency of fish ladders in tropical and subtropical large floodplain rivers. Across the tropics, monitoring studies on fish ladders do not show positive results. A handful of barrages in India have constructed fish ladders, but owing to numerous problems they have been largely a failure. These problems are all related to the extremely low discharge rates from the dams – as there is simply not enough water volume allocated for migrating fishes, which therefore cannot access the ladders and fish lifts. Other problems are linked to siltation in reservoirs and turbulence of flows near the fish passages. For instance, the Farakka fish lifts do not seem to have been of any help due to the extremely low outflow of the Ganga River from it, and the commercial extinction of the Hilsa fisheries both upstream and downstream is clear with an estimated 99.9% decline. Fish passes constructed at barrages on the Yamuna River (Hathnikund barrage) and the Ganga barrage at Haridwar have been monitored by CIFRI and the results suggest that they have had very low success for migration of cold-water species like the Golden Mahseer Tor putitora. Similar structures on the Beas River and Mahanadi River (Salandi dam, Orissa) have found to be ineffective in buffering the adverse impacts on fisheries production in these rivers. India has dominantly followed reservoir hatcheries development, and therefore consideration for effective fish ladders has always been low priority. However, as we have seen, hatcheries themselves bring about several problems for native fish populations – and are not an ecologically viable solution, despite being economically profitable to certain interests. Given the poor success of existing fish passages, it is important to consider modern designs in existing and proposed dams that are suited to the ecology of our own fishes. A whole body of interdisciplinary research – spanning engineering and ecology, is needed to address the significant gaps in our understanding of making fish passages work. We need to monitor existing examples well to assess reasons for their failure. Again, just the act of allowing higher dry-season flows and timely adequate releases in the river could be a far more effective strategy for fisheries improvement than other intensive technology-driven practices to enhance fisheries production (F.pers.comm)

River restoration and alternative livelihoods: Given the current state of riverine fisheries, there is an urgent need to consider possibilities for large-scale ecological restoration of rivers by modifying dam operations and improving ecological flows. Alongside restoration, it is crucial to consider alternative livelihoods to fishers, which regard their traditional knowledge and provide them with clearly defined user rights and responsibilities over management of wild-caught or cultured fish resources. Ecological restoration of all major and minor rivers in India needs to be undertaken urgently, to ensure ecologically adequate, naturally timed flow releases, consistent dry-season flow regimes, hydro-geomorphological habitat maintenance, flood maintenance and reduction in pollution. Dam re-operations to ensure adequate flows and variability in river discharge remain a neglected aspect of river management in most regions today. Flow restoration can lead to improved health, numbers and availability of native commercial carps and preponderance of larger fish sizes through improved juvenile recruitment, along with other advantages to surface hydrology and local groundwater availability. Large-scale scientific research and monitoring programs must be instituted to study the response of inland wild-capture fisheries and take further steps to mitigate local threats. Restoration also needs to involve stringent restrictions on release of untreated domestic and industrial effluent, especially in urban belts such as Kanpur, the National Capital Region of Delhi, Allahabad-Varanasi, Mathura-Agra, Lucknow in Uttar Pradesh; Patna, Barauni in Bihar and the Durgapur and Kolkata regions in West Bengal. Strict restrictions are needed on sand-mining, riverfront encroachment and embankment construction, especially in the Chambal, Ghaghra, Gandak, Baghmati, Rapti and Kosi Rivers. In this regard, more judicial interventions, such as seen recently in the case of sand-mining closures from river beds based on a review by the National Green Tribunal, are critical in reducing wanton and unregulated destruction of riverfronts, when implemented effectively. In terms of reducing the most direct impacts, there is a need to regulate fishing pressure and completely curb destructive fishing practices like dynamiting, use of mosquito-nets, beach seines, and gillnets below allowable mesh-sizes, poisoning, use of long-lines etc. Traditional fishers must be involved directly in monitoring and banning the use of destructive practices by the government monitoring agencies.

Finally, the quest for sustaining fisheries in the Ganga River basin in the long-term will require rethinking of current dominant paradigms to move towards ecological restoration of rivers, their biodiversity, as well as socially just, rights-based and equitable socio-political restoration of traditional fisher communities and fisheries management systems.

Twelve-point recommendation from traditional fisher communities for sustaining riverine fisheries and livelihoods in the Gangetic basin.

Rank	Need	Recommendations
1	Water	Provide enough water, adequate natural flows in all rivers. Allow fish movements upriver, currently blocked by large dams and barrages. STOP new dams and mindless, high-cost, destructive and unsustainable engineering projects such as river interlinking.
2	Ban on destructive fishing practices	Curb destructive practices of fishing, especially mosquito-netting, poisoning, dynamite-fishing, trawling and beach-seine netting everywhere.
3	Poverty alleviation and social security	Fishers are in need of government dole or loans, technical know-how, permits and I-cards, housing, education and displacement packages. It is alleged that these benefits are hardly reaching them, although the allocations of funds reach farmers easily. Fishers need government security from criminals / mafia / anti-social elements / pirates that harass them and grab fish catch.
5	Define fisher rights and responsibilities	Clearly define fishing use and access rights across all riverscapes, provide clear guidelines on multi-objective management of fisheries amidst other economic activities
6	Reduce pollution and mass fish-kills	Urgent need to reduce the presently excessive river pollution, especially industrial but also domestic wastes.
7	Alternative livelihoods	River fisheries are currently in a state of ecosystem-level decline or collapse. Trash fishes have become the most common catch, replacing many commercially viable carps and catfishes. People require alternative livelihoods in situ, to check problems related to migration and exodus to work as construction laborers or rickshaw-pullers. Community-based, cooperative pond carp-culture fisheries seem highly promising. Other alternative livelihoods include working with river management authorities, conservation agencies, ecotourism, agriculture etc.
8	Fishery co-operatives	Focus on community-based management of river fisheries and help it develop in an ecologically friendly and sustainable manner. Replace the systems of private contracts and free-for-all fishing by power-equitable, social dignified resource-sharing arrangements
9	Ensure compliance of fishers towards biodiversity conservation and monitoring	Needs to be ensured through continued monitoring of fishing activity and behavior, including by-catch or hunting of species. This will help safeguard endangered wild species such as gharial, turtles, river dolphins, birds etc. This can also help the spread of exotic food fishes that are rapidly invading our rivers (the worst examples are Tilapia species, Chinese and Common Carps, and more recently, Red-bellied Piranha.
10	Use of Food Security Act, Rural Labor Programs	Can facilitate daily incomes by which fisheries losses could be offset; while also providing a solid community-level incentive to regulate and monitor fishing.
11	Restoration of native riverine fish communities	Very important given the huge decline in native carp species of high commercial value. Fisheries need to protected not only by revival of stocks, facilitating better fish recruitment, but also by protecting fish breeding habitats from
12	Adaptive management of water tenure in fishing areas	Owing to natural uncertainty linked to flow regimes and channel course changes, new flexible systems of tenure in fisheries are required. Such systems would fit in well with providing a clear definition to fishing rights in any riverine stretch.

Rivers and Water in Union Budget 2014-15

July 10, 2014July 11, 2014 SANDRP1 Comment

In the first annual budget (for the year 2014-15) presented by the new NDA government at the centre on July 10, 2014, it is generally bad news for Ganga and other rivers. Below we have given various provisions on water and river from the budget speech of the Finance Minister Shri Arun Jaitley. Mr Jaitley said in his speech: “In the first Budget of this NDA government that I am presenting before the august House, my aim is to lay down a broad policy indicator of the direction in which we wish to take this country.” The broad policy indicators on rivers do not seem to be any good news for the rivers of the country.

RIVERS FM said, “Rivers form the lifeline of our country. They provide water not only for producing food for the multitudes but also drinking water.” This shows the limited understanding of rivers that the government has. Rivers provides so much more than water. The FM do not seem to have any good news for this lifeline as the budget has several proposals that will harm and destroy the rivers.

River Linking The PIB wrongly claims, “The Budget also contains the first ever effort to link the rivers across the country.” A sum of Rs. 100 crore in the current Budget to expedite the preparation of Detailed Project Reports has been set aside. This is waste of public money. In addition to this, there is a huge allocation for the annual budget for NWDA, whose only mandate is studies for river linking. It is existing for 22 years, but has not produced a single document that will pass independent public scrutiny, and NWDA is afraid to put any document in public domain. Why is the government spending money on such fruitless exercise?

GANGA: Integrated Ganga Conservation Mission The Finance Minister, Shri Arun Jaitley said, “I propose to set up Integrated Ganga Conservation Mission called “Namami Gange” and set aside a sum of Rs 2,037 crores for this purpose.” Shri Jaitley said that the Mission is being launched because a substantial amount of money has been spent in the conservation and improvement of the river Ganga but the efforts have not yielded desired results because of the lack of concerted effort by all the stakeholders. This is admission of even NDA’s failure, since they were in power for at least six years and have not been able to make a dent in the state of the river. They should learn from that experience before jumping into such missions.

This raises a lot of unanswered questions: There is already an existing National Mission for Clean Ganga and if this new mission will be in addition to the old one or if the old one will be abolished? What is new in the new mission? Strangely, the FM did not use the work Ganga Rejuvenation, the charge that Ms Uma Bharti has been given. Does this indicate something is amiss here?

Riverfront Development “The Finance Minister has also set aside a sum of Rs. 100 crore for Ghat development and beautification of river front at Kedarnath, Haridwar, Kanpur, Varanasi, Allahabad, Patna and Delhi in the current financial year since Riverfronts and Ghats are not only places of rich historical heritage but many of these are also sacred.”

The trouble is, this could spell disaster for the river and the cities where such development is planned, if this is going to happen on the lines of Sabarmati river front development. This is because in case of Sabarmati, the Riverfront development meant encroachment of over 200 ha of riverbed. If this is followed the river’s carrying capacity will be reduced. In changing climate, rivers need more and not less carrying capacity as the events of July 2005 in Mumbai, of August 2006 in Surat & recent years in Delhi have indicated. During Uttarakhand disaster of June 2013 the buildings that we saw collapsing were all standing on the riverbeds. That should be a warning for any riverfront development that would encroach on the riverbed.

NRI Fund for Ganga To harness the enthusiasm of the NRI Community to contribute towards the conservation of the river Ganga, an NRI Fund for Ganga will be set up which will finance special projects, the Finance Minister added.

“A project on the river Ganga called ‘Jal Marg Vikas’ (National Waterways-I) will be developed between Allahabad and Haldia to cover a distance of 1620 kms, which will enable commercial navigation of at least 1500 tonne vessels. The project will be completed over a period of six years at an estimated cost of Rs 4,200 crore.”

Watershed Development To give an added impetus to watershed development in the country, a new programme called “Neeranchal” will be launched with an initial outlay of Rs 2,142 crore in the current financial year. This could be a positive move, but we have to await the details. It is also not clear if this is in addition to the ongoing watershed development or in place of it.

Rural Drinking Water For providing safe drinking water, Rs 3600 crore has been earmarked under National Rural Drinking Water Programme in approximately 20,000 habitations affected with arsenic, fluoride, heavy/toxic elements, pesticides/fertilizers through community water purification plants in next 3 years, the Finance Minister added.

Delhi Water Reforms Rs. 500 crore for water reforms to make Delhi a truly World Class City. The budget does not say a word what these reforms would mean, but going by the track record of this government in past, when they say reforms, they mean privatisation, which will be strongly opposed in Delhi.

Allocation for Renuka has no justification The FM said, “In addition, to solve the long term water supply issues to the capital region, construction of long pending Renuka Dam would be taken up on priority. I have provided an initial sum of Rs 50 crore for this.” Firstly Renuka dam does not even have statutory forest clearance and NGT has stopped work on the project. FM, but allocating money for the project in such a situation has indicated that they do not care for statutory clearance process or judicial orders.

Moreover Delhi does not need any more water from outside. It is already privileged with per capita water availability of over 250 lpcd, which is more than most European cities. Delhi does not harvest rain water, does not use flood water to recharge, does not protect its water bodies, does not treat its sewage, does not recycle and reuse the treated sewage, does not reduce its losses, does not do demand side measures and like a spoilt kid, asks more and more water from long distance sources.

Thirdly, Delhi may want exclusive share in water from Renuka, but Upper Yamuna states of Haryana, UP, Uttarakhand, Rajasthan, Himachal Pradesh and Chandigarh are all asking for their share from the project and are ready to share the costs. Going ahead with the project without resolution of the interstate issues may land us in a soup similar to the Munak Canal.

Allocation for Statue of Unity The budget provides Rs 200 crore for ‘Statue of Unity’ in Gujarat. This project is come up in eco sensitive zone, and will affect large no of people and water body, but it has not seen any social or environmental impact assessment or participatory consultative process. It is supposed to come up in the middle of the water reservoir to be created by the proposed Garudeshwar Dam on Narmada river, but that dam has no impact assessment or clearances and stands challenged in NGT. Allocating money for the project under the circumstances is inappropriate.

Welcome Move: National Centre for Himalayan Studies in Uttarakhand “There is a great need to increase the capacity in the country for Himalayan Studies. I propose to set up a National Centre for Himalayan Studies in Uttarakhand with an initial outlay of Rs 100 crore.”

Irrigation The Budget provides Rs. 1,000 crore for Pradhan Mantri Krishi Seenchaayi Yojana. If this is for decentralized local systems, it would be a welcome move, but no details are available.

Welcome move: Organic farming in North East India Rs 100 crore has been provided in the budget to promote organic farming in Northeast India. This is a welcome move.

Welcome move: National Climate Change Adaptation fund for small farmers The FM said, “Climate change is a reality which all of us have to face together. Agriculture as an activity is most prone to the vagaries of climate change. To meet this challenge, I propose to establish a “National Adaptation Fund” for climate change. As an initial sum an amount of Rs 100 crore will be transferred to the Fund.” This is welcome, but we need to see who corners this money. It should go to the rainfed farmers.

Some other welcome provisions: Finance to 5 lakh landless farmers through Nabard since landless are not able to get bank loans in absence of land as a guarantee; Rs 50 core set aside for blue revolution for inland fisheries. This is provided there is a move to conserve the riverine fisheries.

On the whole, in spite of some welcome moves, on the whole, the budget brings more bad news for the rivers & those depend on rivers and rains, than good.

How do dams affect a river?

July 4, 2014July 4, 2014 SANDRP7 Comments

That sounds like a rather innocent question and I was asked to write an article, addressing it. But before we go into that, let us try and understand a few things. Firstly, what is a River? Let us first try and understand that.

There is no single definition of this complex entity. For every definition, there is something more a river does.

Take the example of the one of the most complex rivers of all, the Ganga that we think we know. Before being a religious entity cultural icon, etc Ganga is, first & foremost, a River. A perennially flowing river like Ganga flows all the time. But that flow is not constant. It changes from day to night, from one day to another, from one season to another, one year to another, from one place to another.

And then, the Ganga that we know is not only a single river but a collection of rivers. So Yamuna, Bhagirathi, Alaknanda, Mandakini, Dhauliganga, Pinder, Ramganga, Kali, Tons, Gomti, Ghaghra, Sone, Gandak, Budhi Gandak, Kosi & Mahananda are some of the major tributaries that directly meet Ganga. Each of them is a river in its own right.

Take Yamuna for example. Some of its major direct tributaries include: Tons, Giri, Som, Sahibi, Hindon, Chambal, Sind, Betwa & Ken, each of them are again significantly big rivers.

Take Chambal, some of the major direct tributaries of Chambal include: Parbati, Kali Sindh (Lakhundar, Ahu, Parwan are some of the tributaries of Kali Sindh, Newaj is one of the tributaries of Parwan, Dudhi is one of the tributaries of Newaj), Banas, Ider, Retam, Sau, Kshipra, Chhoti Kali Sindh, Cham, Siwana, Kural: each of which is a river by its own right.

Take Parbati: some of the major tributaries of Parbati include: Papnaus Ajnal, Sewan Paru, Utawali, Paraparwa, Mawal, Tem, Bhader, Gochi, Gaumukh, Sunk, Negri, Chopan, Uproni, Duhral, Andheri, Beram, Kosam, Ahelil and Sukni. These are all rivers too!

We can go on like this much longer. But such is a vast network of rivers that we call Ganga.

Secondly what flows in a river is not just water, though most governments, official agencies & engineers see the rivers as channels of water. Flowing water is surely a major visible defining component of a river. But even a canal or a pipeline can claim that. But unlike a canal or pipeline, a river carries dissolved matter, suspended matter, bed load, microorganisms, many levels of aquatic flora and fauna.

Thirdly, a river is a connected entity. It is connected with upstream and downstream river, biodiversity & landmass, the terrestrial land & life, underground geology and groundwater aquifers and is also connected with the floodplain. Perennial rivers like Ganga meet the sea forming a delta and this connection is vital for the river and as well as the sea. The connections are so strong that a river provides a report card about what is happening upstream and downstream, if read carefully.

From: The River continuum Concept. Species in India will be different, but this represents how biological entitites in a river are linked to each other through a number of processes including nutrient spiralling Oxbowriver.com

This is admittedly a partial description of a river, limited by the constraints of an article or blog. This is also a bit simplistic description of how humans deal with rivers, since there are exceptions. But this provides a broad direction of our journey with the rivers.

Apart from its many functions like ecological, hydrological, geomorphological ones, a river is also connected with the human society along the banks. The connection with human societies has been as long as the humans have existed. This connection is not really necessary for the river to survive, but we cannot say the same about human survival. Humans cannot survive without the rivers, though is doubtful if the human society understands or even acknowledges that reality.

More importantly, till about a century ago, our interaction with the rivers did not endanger the existence of the rivers themselves. But what we have been doing in last century has created existential threat for rivers. This threat comes in the form of big dams, diversions, chemical pollution from agriculture and industries, large dose of sewage pollution at major urban centers, encroachment on floodplains, deforestation, unsustainable groundwater use, riverfront developments, embankments, and climate change.

What humans have done to the rivers in last century can possibly be described as Terraforming (one of the grandest concepts in science fiction in which “advanced” societies reshape entire planets to suit their needs). Or what some geologists describe as Anthropocene, meaning a new geological age of humans to suggest that humans are now a planet transforming force.

It seems humans have stopped valuing the rivers as they exist in nature and decided that they can stop, bend, tunnel, channelise, divert, encroach, pollute the rivers. So when we build a dam, we do not put any value to the destruction of river & destruction of the services provided by a river that entails in the process of building the dam.

But let us get back to Rivers & what dams do to them. A river, by definition, must flow freely. A dam stops the free flow of river, and impacts the river in the most fundamental ways. In India when we construct a dam (e.g. Tehri), a hydropower project (e.g. 400 MW Vishnuprayag project on Alaknanda in Chamoli district in Uttarakhand) or diversion (Lower Ganga – Bhim Goda at Haridwar, Middle Ganga – Bijnor and Upper Ganga-Narora barrages), we do not have to leave any water for the downstream stretch of river. So complete drying up of the rivers for most of the dry months by these structures is the first direct impact of these structures on the river. To put it mildly, that action practically kills the river. Upstream of the dam too, the river gets killed, for immediate upstream there is stagnant water and further upstream, the river has lost its connections with the downstream river!

This is because these structures not only stop the flow of water to the downstream areas, they also stop flow of everything else that was flowing in the river: the silt, the nutrients, the sand, the organisms, the flora, fauna, and severe every one of the connections of rivers we described earlier

And imagine when a river has to face such death every few kilometers in its journey!

Density of dams in the Upper Ganga Basin Map by SANDRP

That is not all. As the river continues its journey, if the tributaries are flowing reasonably freely, there is some chance for the river to recover some of its defining characteristics. But we have dammed most major tributaries too.

To top it, we also have other elements that help kill the river, like pollution, encroachment, abstraction, etc, as described earlier.

And remember just about a century back Ganga and other rivers were not in such a bad shape. This is an achievement of less than 100 years.

Chandra Basin in Himachal Pradesh depicted by Nicholas Roerich in 1932. The same Chenab Basin now witnesses one of the highest dam densities in Himalayas. From: WikiArt

Some people will read in this a plea to go back by those 100 years. That is not possible, and we all know that. But there are other ways to deal with the rivers. Human society can take what is needed for the society, without destroying the river.

This is true of Ganga, as any other River!

Dams

Ganga in Peril: Building more barrages will finish it off

June 27, 2014June 27, 2014 SANDRPLeave a comment

By Anil Prakash

Rivers are not simply rivers, but they are our cultural life lines. Freshwater of rivers, fertile land on either side and island inside them, living beings, plants and vegetation and millions and millions of human beings, laughing and singing and shedding tears of sorrow, all taking together constitute the world of rivers. Men tried to fetter these rivers and construct dams, hydropower projects, riverfronts, embankments and barrages over them, encroached the floodplains, all in the name of progress. But the rivers want to break these fetters, as if they are giving a message to mankind to break the fetters of slavery, and to live a free and natural life. Whenever obstructions are put to them or they are polluted, they break their self restraint.

GOOGLE IMAGE OF FARAKKA BARRAGE

The 2245 m long Farakka Barrage is one of the most debated river management projects though for reasons which have nothing to do with either environmental or demographic reasons. Built primarily to serve the twin purpose of regulating the amount of Ganga water to flow out from the Indian territory into Bangladesh (East Pakistan then); and to ensure that sufficient water is diverted to Hooghly river to enable the regular flushing of silt at Calcutta port, the Farakka Barrage has been more often mired in controversy as India and Bangladesh have disagreed over the share of Ganga water between the two countries. While in the recent past, some efforts have been made to resolve this contentious dispute between the two nations, no thought has been spared so far on the long term impact the barrage has already caused and continues to do on an ongoing basis.

Though the Farakka Barrage was commissioned in 1975, work on the project had been going on for long. The structure of the Barrage was completed as early as in 1971 but the feeder canal which diverts water to the Bhagirathi river (as the Hooghly is called at this point) was completed only in 1975. By this time however, the cost of the project had escalated and when it was finally completed, the Farakka Barrage cost the nation Rs. 156.49 crore. The cruel irony is that since its commissioning, the Farakka Barrage has cost the nation much more but leave alone calculating the total cost, barring a handful, no one is even willing to concede the fact that the Barrage has caused irreversible harm to environment and society. The Barrage is being maintained by the Farakka Barrage Project (with 878 employees[1]), under Union Ministry of Water Resources, with jurisdiction upto 40 km upstream of the barrage, 80 km downstream along the right bank feeder canal and in the downstream area upto Jangipur barrage[2].

The Farakka Barrage was modelled on the lines of the Damodar Valley Corporation (DVC)- one of the first major riverine projects undertaken by the Central government under the influence of Nehruvian model. Both the DVC and the Bhakra project in the northern India were reflective of the government’s viewpoint that river management projects in India needed to be modelled on western lines – with its emphasis on large dams. In fact, plans for the DVC had already been drawn up by the British before independence during Lord Wavell’s tenure as Governor General. The entire project was modelled on the lines of the Tennessee Valley Authority of America and its chief engineer was actually appointed by the government of Independent India as the Chief Administrator of the DVC. When the DVC was planned and work on it was initiated in the late 1940s & early 1950s, the government was lavish on its claims regarding the benefits from the project. For eastern India, the DVC was considered to be a panacea to several problems in areas of power, irrigation and flood control. But as experience later showed, the claims had been falsely made on all fronts: the DVC in fact, made more areas in West Bengal prone to flood than before; the project’s utility in irrigation & power generation programmes was minimal.

Faulty Projections

By the late 1950s evidence was mounting that the projections made by the planners of the DVC had got it all wrong. The greatest demerit in the DVC was the sharp decline in the discharge capacity of Damodar river: from a level of 50,000 cusecs in 1954, the figure touched abysmal level of 20,000 cusecs. By 1959, the depth of Calcutta port had declined considerably after the construction of the Maithon and Panchet dams. The discharge capacity of several other rivers in the region like Jalonshi, Churni, Mayurakshi, Ajai and Roopnarayan also declined greatly and further contributed to the rising bed of the Hooghly. The situation slowly started reaching the point of no return and by the late 1950s, large ships stopped coming to Calcutta port and instead opted for Diamond Harbour.

SANDRP MAP OF DAMODAR VALLEY DAMS

These facts were not hidden from the policy makers and planners when work on the Farakka Barrage was initiated. Yet, they chose to remain myopic and contended that the Barrage would flush out silt and mud from the Hooghly and thereby it would be possible to reclaim Calcutta port. What was ignored was the fact that till the DVC project had been initiated, the problem of Hooghly not getting desilted had never risen because of the nature and timing and force of the floods in the Damodar and Roopnarayan rivers. But, once various dams came up in the course of the DVC, these rivers lost their capacity to flush the Hooghly thereby jeopardising Calcutta port.

The Farraka Barrage was thus intended to correct a un-envisaged adverse impacts created by DVC dams. However, as events have proved, the step taken to correct a previous wrong move also turned out to be a faulty and unwise decision. However, it is not that words of caution were not available when the DVC dams or the Farakka Barrage were initially planned: they were only not heeded. To illustrate, Kapil Bhattacharya, an engineer in West Bengal contended that the amount of water that could be diverted from the Farakka Barrage into the Bhagirathi, would not be sufficient to flush the Hooghly to the level that Calcutta could once again be used as a port. He also suggested that the DVC should be modified in a manner so that water from river Roopnarayan flows into the Hooghly which would ensure regular flushing of the river. Regarding the Farakka Barrage, Bhattacharya further said that the project would reduce the water carrying capacity of the Hooghly and thereby make more areas in West Bengal prone to floods. He had further cautioned that there would be heavy silt accumulation even in river Padma on the Bangladesh side of the border and this would further make areas on the right bank of Padma flood prone.

Creating Problems at both Upstream and Downstream

An alarming development has been the steady decline of the Ganga’s depth. In 1975, when the barrage was commissioned, the depth of the river at the barrage was 75 feet. In March 1997 when I visited the area with some friends, we were shocked to find that the depth of the river was only 13 feet. In effect, this means that the bed of Ganga had risen by 62 feet in the past years. Latest report shows that Ganga has become a havoc and the erosion goes on increasing year after year at Malda and Murshidabad districts.

Actually the Ganga river system transports vast amount of fluvial sediment. The Ganga used to be desalted up to 150 feet during flood season every year. On construction of Farakka barrage natural flushing of the sediment has been obstructed.

Ganga Basin Map (source: https://sandrp.in/basin_maps/)

This alarming development has led to untold misery to the people of Gangetic region of West Bangal, Bihar and Eastern UP as the level of the bed of all tributaries of Ganga has risen steadily. As a result, thousands of Chaurs (lowlands) that previously used to remain flooded only during the monsoons, now remain submerged under water for as long as ten months. The problem of constant water logging not only leads to possibilities of the outbreak of infectious diseases, but also causes unfathomed economic and social miseries on the people in these regions. Nature of the soil becomes alkaline and already lakhs of acres of once fertile land in Bihar have now turned totally barren. The fertility of the Gangetic plains today is a poor image of yesteryears.

While the problem of submergence as a result of the Farakka Barrage is acutely felt upstream of the barrage, the problem is one of erosion downstream of the barrage. As the water discharged into the Bhagirathi and the Padma is devoid of any silt, the water tends to cut into the land more sharply than in the past. As a result the problem of soil erosion is being very acutely felt in villages and towns on the banks of the Bhagirathi.

Depletion of Fish Resources

Besides water depletion, river diversion and dam projects also wreak havoc among the fish living in these waters. These projects adversely affect the fisheries which are migratory in nature. Dams and barrages act as barriers in their migratory paths and several species have either already become extinct or are facing extinction as they breed in a particular type of water while inhabiting in a different sort. The Farakka barrage has over the years acted as a barrier to the migration of marine & deltaic fish leading to the near absence of several popular varieties in the entire northern India. As the waters of several rivers of northern states directly or indirectly flow into the Ganga, there is a similarity in the type of fish found in the rivers. There are many aquatic verities (for instance prawn) that inhabit in fresh water but breed in marine water. Likewise, there are other species – like Hilsa – that inhabit in marine water, but have migrated upstream to breed. The Ganga once used to have plenty of Hilsa but this has changed as the fish is no longer able to breed leading to the near extinction of the Hilsa in the Ganga upstream of the Farakka Barrage.

In fact, it is not just a question of Hilsa alone, but there has been a substantial drop in the fish population on the entire Ganga. Prior to the barrage, during monsoon, there used to be a very high population of eggs and spawns in this stretch (UP and Bihar upstream of Farakka) of Ganga. After catering to the local needs (there is great demand for fish in Bihar and eastern UP) a substantial amount of eggs, prawns and different varieties of fishes used to be sent to other states. Today barely about 25 per cent of the local demand is met by the fish caught in this stretch and for the rest; the people have to depend on fish caught in other states.

It has been estimated that there has been an overall decline of 80 per cent in the entire population of fish upstream of the Farakka Barrage. Large fish, once found in abundance in the Ganga and its tributaries are no longer available and millions of traditional fishermen who have made their living for generations by catching fish now face destitution. What had previously been a close relationship between the fishermen and local customers have now been replaced by a cold system comprising air-conditioned trucks and ice-laden crates of fish brought in by large companies from other states like Andhra Pradesh. This not only makes the fish beyond the reach of the poor, but also alienates traditional fishermen from their ancestral profession in a situation where they do not have the training to do other jobs.

The Farakka Barrage has adversely affected the ecology and economy of Bangladesh too. Before 1975 Ganga used to flush out the Padma basin in Bangladesh and spread the alluvial soil in agricultural fields. But the barrage has disrupted this natural process. Now tides of the sea fill sand in the bed of Padma and also fields around it. Lakes and ponds are filled with saline water. The ground water level has fallen down resulting in drying up the shallow tube wells and dug wells. The Barrage has caused serious damage to land and populace both upstream and downstream of the barrage. Corrective measures are called for immediately and if not taken then there are portents of much greater havoc both to the people and to the land.

Chain of barrages will worsen the situation

The new plan of union government[3] to built chain of barrages along Ganga, every 50-100 KM will further worsen the situation. Natural process of silt transport and distribution in flood plains will be completely obstructed and breeding of migratory fishes will be further disturbed. The government should review this plan. A high level inter-disciplinary team need to be appointed to study at length the problems that have surfaced on account of the Farakka barrage and suggest measures that can be initiated to reverse the process of the damage. This plan will not succeed in either making Ganga Navigable or help the cause of rejuvenation of Ganga that the new government claims it is committed to. Strangely, the plan was announced without any details, public participation, environmental impact assessment, social impact assessment, public participation or participatory decision making. Free flow of Ganga is essential for rejuvenation of this holy river.

Ganga Mukti Andolan

Since 1982 fisher-folk and peasants of gangetic region are contending that rivering projects like dams, barrages and embankments are leading to economic downfall on account of fish depletion, submergence and fertile tracts turning alkaline. The Ganga Mukti Andolan has its origins in the resistance to the system of ‘Panidari’in Bihar. Under this system, waterlords and power contractors had fishing rights of Ganga and its tributaries. After a long struggle zamindari (Panidari) and contract system was abolished in January 1991 and traditional fisher people were given free fishing rights in 500 KM stretch of Ganga and in all rivers passing through the Bihar state. The movement continuously raised the issue of pollution caused by factories and thermal power station. Ganga Mukti Andolan has thus, moved from a movement of social and economic equity to one that questions the very model of development that is destroying the Ganga and those who depend on it. The movement wants a new direction for river management.

Dams

Water for Power: Irrigation Dam to be Used for Thermal Power- Drinking Water Supply of BHU, Agriculture, and Existence of Waterfalls at Risk

March 20, 2014March 20, 2014 SANDRP2 Comments

Welspun Energy which is famous for renewable sources of energy like solar and wind power plants in India, is now becoming more infamous in thermal power sectors in India. While, the Environmental Clearance of one of its thermal power plant in Katni (Madhya Pradesh) is under controversy since 2 years alleging fake public hearing and protests from farmers for forcefully acquiring land with help of local administration,… an action replay is observed in another thermal power plant proposed by the company in Mirzapur district of Uttar Pradesh. While High Court of Madhya Pradesh has issued notices to Central and State government of M.P. for Katni Thermal Power Plant raising question on the whole EIA process[i], the proposed 1320 MW Mirzapur thermal power plant is awaiting EC and is facing huge opposition from local people and Banaras Hindu University which has its new 2700 acres of south campus very near to the project site. Students of BHU even sent a written petition to MoEF alleging that public hearing was not communicated properly and the EIA concealed several critical information.In this article, we tried to highlight the issues related to water where the company has been alleged to conceal information and not taking into account the factors which will is bound to have significant impact on environment.

A 1320 MW coal based thermal power plant is proposed at village Dadri Khurd in Mirzapur by M/s Welspun Energy (U.P.) Pvt. Ltd. Issues like concealment of wildlife data and utilizing forest areas caught the eyes of environmentally concerned people after the Site Visit report prepared by Vindhya Bachao was made public. One of the key issues raised was the impact of water withdrawal and the manner in which it is proposed in the Environment Impact Assessment (EIA) report. The project proponent concealed information regarding the presence of an entire river, water-falls, a University campus of 2700 acres and the fact that the same water source provides drinking water to the entire campus!

The project was considered for Environmental Clearance by Expert Appraisal Committee (EAC) – Thermal Power and Coal Mines on 26^th March, 2013 and 18^th November, 2013, and was deferred both the times. Local activists and Banaras Hindu University have made representations for shifting of this project to MoEF (Ministry of Environment and Forests) already. The project is being under consideration for third time by EAC in its meeting dated 25^th March, 2014. This article presents a short summary of the contradictions between the claims made by the Company and the reality at the ground level. It also illustrates the extent to which a company can go to mislead the authorities to get an Environmental Clearance.

1. No EIA of withdrawal of water from Ganga

Ecological Flow ignored while giving NOC to withdraw Ganga water

The project proponent wrote in its EIA that 40 lakh liters of water per hour will be required by the power plant which will be withdrawn from River Ganga via Upper Khajuri Reservoir. In the NOC (No Objection Certificate) letter given by CWC (Central Water Commission), the dry period of Ganga has been written as January to May. According to researchers based in Varanasi and Mirzapur, the water flow in Ganga improves only around July after the onset of monsoons. Apart from this, one can visually make out the state of river Ganga in Mirzapur which starts drying in October and by November end, the river looks completely dry. In any case, the extraction of water in lean season will not only affect the river ecology but the livelihood of people dependent on the river as well specially the fishermen. Mirzapur stretch also reportedly has Gangetic Dolphins, which will be also affected due to the proposed activity. However, it is ironical to see that the country’s premier institutions like CWC ignored the water flow of Ganga at Mirzapur while giving NOC to withdraw water. Not only the lean season has been altered for the project but the high level of pollution in Ganga has also kept aside while allowing so much water (36 MCM) to be pumped for the power plant. Mirzapur lies between Allahabad and Varanasi, both of which lie on the banks of Ganga, and are responsible for its severely polluted state. No doubt the water quality of Ganga at Mirzapur is not great and there should be enough water present in the river to allow safe dispersal of pollutants and improving the self cleansing capacity of the river. In such a crisis, the decision of the CWC to allow withdrawal of water from Ganga is extremely incongruous.

In a response to a representation that we sent to the MoEF regarding this, the company replied that they are using just 0.0003% of total 60,000 Cu.mec. water flow in the Ganges. It must be mentioned here that this calculation was based on the consideration of 4 lakh litres of water required per hour, instead of 40 lakh/hour. As discussed earlier, such huge extraction of water will have significant impact on the river flow in lean season. There has been no impact assessment of the withdrawal of water from Ganga which was required to be done as per the TOR issued to the project.

The Distance of Upper Khajuri Reservoir by road from Mirzapur is at least 24 Km and from Upper Khajuri reservoir to the proposed site is another 7 Km. The elevation of the proposed project site is at 630 feet while the elevation of Upper Khajuri dam and river Ganga is at approx. 510 feet and 260 feet respectively. The pipeline crosses through several Reserve Forests like Barkachha RF, Daanti RF, Marihaan Reserve Forest and Patehra which are home to at least six Schedule I species including Sloth Bear, Chinkara and Vultures. According to a reply under RTI application from the forest department, it is also noted that the region has a very small population of Swamp deer and Mugger Crocodile too.

2. Diversion of Irrigation Reservoir to Industrial Use, was there any participation of the affected people in this decision?

i) Imprudent approach to use Upper Khajuri The project proponent says that the water for dry season of Ganga will be met from Upper Khajuri Dam, which will be filled up during monsoon.The company also added that 9.5 MCM will be also pumped for agricultural needs of the people. Firstly, the reservoir is very much in use and is source of irrigation and drinking water. The subsequent question that arises is whether they have the permission for additional 9.5 MCM to be withdrawn and whether there is any checking mechanism to monitor that only 36 MCM water is being pumped and no more? Will they be able to maintain the water quality, which will be effected due to ingress of Ganges water?

According to the information available on WRIS-NRSC website, the Upper Khajuri Reservoir is a very old reservoir developed in 1962 as a medium irrigation project with potential created at 7280 Ha with a live storage-capacity of 37.834 MCM.

Our concern here is, whether the idea of filling up of a rain-fed reservoir with the severely polluted water from Ganga will solve the problem or escalate it? There are several agricultural fields adjoining Upper Khajuri reservoir that will be submerged. In addition, the clean water available to the farmers will be completely jeopardised and there will be increased threat of contamination of the fields due to the constant filling of polluted water from Ganga. It is worth noting that the current source of water for the reservoir is rainfall surface run-off which gets enough time to clean its water from suspended particles and other contaminants.

ii) No Mention of downstream features and impacts of alteration to Upper Khajuri reservoir The EIA report does not mention the important downstream features and uses of Upper Khajuri Reservoir. The Upper Khajuri Reservoir (UKR) is connected to Lower Khajuri Reservoir (LKR) via River Khajuri. River Khajuri runs alongside the Banaras Hindu University’s South Campus (A k.a. RGSC-Rajiv Gandhi South Campus) and has to two of the famous water-falls of Mirzapur, namely Wyndham Fall and Kharanja Fall.

Wyndham fall is a very famous historical water fall and nature park being maintained by Forest Department, which is on River Khajuri. The length of the river between Upper and Lower Khajuri Reservoir is very short, which is approximately less than 10 Km. The LKR is the source of drinking water to the entire BHU South Campus and any alteration to Upper Khajuri Reservoir will directly affect the Lower Khajuri Reservoir as both of them are connected via River Khajuri.

The EIA report not only ignores the presence of 2700 acres of RGSC-BHU, but also does not even mention the presence of River Khajuri, Wyndham Fall and Lower Khajuri Reservoir (LKR). LKR, commissioned in 1949 as per CWC register of Large Dams in India has gross storage capacity of 120.37 MCM (Million Cubic Meters). UKR, commissioned in 1958 has gross storage capacity of 44.74 MCM and live storage capacity of 37.83 MCM. As CWC register shows, both are irrigation projects.

A representation from Banaras Hindu University has already been sent to MoEF on 18^th September, 2013, in which they have mentioned that any alteration to Upper Khajuri will jeopardise the drinking water source of the campus. In the same letter it has been demanded to shift the site of the project far from the campus.

Opposition is also coming from the students of RGSC. Students recently sent a petition with more than 500 signatures showing opposition to the use of Upper Khajuri dam and saying that Khajuri River has cultural values for the students and they are sentimentally attached to the river system, especially the Wyndham fall and Kharanja fall. They also showed concern regarding water quality as it is also the source of drinking water for them. The same petition also alleged that the information about public hearing was not communicated properly, due to which no one from RGSC could participate in the Public Hearing and register their complaint.

3. No Impact on water resources?

Under the Terms of Reference recommended by MoEF for EIA of the project, it was mandatory to:

“Study on the impact on river/marine ecology (as may be applicable) due to the proposed withdrawal of water/ discharge of treated wastewater into the river/ creek/ sea etc shall be carried out and submitted alongwith the EIA Report.”

The company repeatedly maintained in the EIA report that there will be no impact on water resources due to the project.

In the EIA report they wrote that the project will be designed for zero waste water discharge and the waste water generation will be only 1% of freshwater withdrawn. This magical prediction is based on their theoretical design. However, it is highly impractical. Moreover, there is no mention of River Khajuri, Wyndham fall and most importantly, the fact that the same water source is also used for drinking water by BHU and also irrigation. Apart from withdrawal of water, what concerns us is the impact of water pollution on the water sources. In a thermal power plant project, the water pollution range from discharges from cooling tower blow down, boiler blow down, demineralisation plant effluent, coal handling plant dust suppression, ash handling, Leachate of heavy metal (especially Mercury) from ash pond, effluent from oil handling and transformer areas, power house and turbine area effluent and domestic waste water. No detailed assessment of impacts on water due to withdrawal or discharge is given in the EIA report.

Though the company’s arguments have seems to have convinced State Government and Central Water Commission, it is becoming very hard for the BHU Professors to accept that this will not jeopardize the drinking water supply of the campus. As the Upper Khajuri dam and river Khajuri is being used extensively for drinking water, this will severely affect the water quality. As the length of river Khajuri between UKR and LKR is short, one cannot expect the self cleaning capacity of the river will be too sufficient. The impact of the water withdrawal on the aquatic ecology, groundwater recharge, irrigation, water falls was also required, none has been done.

EAC in its meeting dated 26^th March, 2013 raised this issue to project proponent and asked for some other alternative water source for the project site, since the dam was constructed for drinking and agricultural needs and not for industrial purposes.

In our representation to EAC we also emphasized that water from Ganga will have very very high levels of BOD, coliforms and other pollutants, which will cumulatively jeopardize the water quality in the streams leaving this entire region in severe crisis of drinking water. Apart from that, contaminants like Zinc, Aresinc, Chromium, Phosphate, Copper and radioactive element like Uranium will impose heavy threat to the water quality of the local water sources as the waste water will be finally discharged in local nallah which will drain either into Khajuri river or some other wetland. The company has still kept a mum on the disclosure of that local nallah till now, where the wastewater is to be discharged.

On raising the issue regarding water discharge and impact on water resources to EAC in November last year, the company responded as follows:

“The desired water is sourced primarily from Ganga River flowing at a distance of 17 km from project site for which desired approvals have already been obtained from State & Central Government. The same is only intermediately stored at Upper Khajuri Dam, which is finally pumped to reservoir at project site. Therefore, our source of water is not common as Vindham Falls…

I. Referring Point No. I, we confirm that Upper Khajuri Dam will be used as intermediate storage of water from Ganga & ultimately will be pumped to our project site after fulfilling the commitment with State Government for irrigation & other purposes of local community…

Total water requirement for power project including irrigation requirement would be met by pumping water from river Ganges and storing In Upper Khajuri Dam and there is no conflict of interest as for as BHU and Vindham fall is concerned.”

We just hope EAC takes note of the silly and unscientific replies of the project proponent while making any decision in future of this project. In any case, an assessment of the quality of the Ganga water, how it will affect the UKR and Khauri river and downstream ecology and how will it ensured that water used by the company will be exactly same as the water pumped from Ganga minus the losses? Why can the project not be asked to build their own facility rather than using the UKR?

4. Other Issues with the Project There are numerous environmental issues which were raised by Vindhya Bachao in its ‘Site Visit Report’ submitted to MOEF on 15^th November, 2013 – including location of the project site inside a forest area, presence of Schedule I animals in the project site – which are in direct contradiction to the claims made in the EIA report that no forest land is involved and no endangered animal is present in project area. Some other issues were also reported like illegal means of getting signatures in support of the project in the form of job application form. The Site visit report prepared by Vindhya Bachao, BHU’s representation and all EIA documents of the project can be accessed at www.vindhyabachao.org/welspun.

It is also interesting to see what stand Mr. Narendra Modi, BJP’s prime ministerial candidate who will be contesting from Varanasi, just 60 km downstream of Mirzapur, will take. While he tries to woo people of Varanasi for clean Ganga, will he understand the ecology of Ganga? And can he prevent further destruction of this mighty, holy river from companies like Welspun. This becomes particularly interesting since Welspun has flourished in Gujarat under Modi’s rule.

IWMI report on Glaciers and Snow cover in Himalayas in Changing Climate: Significant Impact on Seasonal flow of the Rivers in India

August 18, 2013September 7, 2013 SANDRPLeave a comment

International Water Management Institute (IWMI) has recently published a study named Glacier Systems and Seasonal Snow Cover in Six Major Asian River Basins: Hydrological Role under Changing Climate, authored by Oxana S. Savoskul and Vladimir Smakhtin which claims that the hydrological role of the melt-water resources in six major rivers e.g. Indus, Ganges, Brahmaputra, Syr Darya, Amu Darya and Mekong of the Hindukush-Himalayan region (HKH) has been comprehensively assessed for the first time on a basin scale. Reviewing already published studies, this report draws some interesting conclusions regarding the role of glacier and snow meting for six river basins which includes three major rivers basins of India.

The map below shows area of the river basins included in this study. In this report, the term ‘melt-water resources’ has been used to cover glacier systems and seasonal snow cover. This report uses 1961-1990 status of melt-water resources as the baseline and compares with the 2001-2010 using the following characteristics: specific glacier runoff (average depth of annual discharge from glacier-covered area), basin total glacier runoff, shares of renewable and nonrenewable components in glacier runoff, total seasonal surface snowmelt from non-glaciated areas, portion of seasonal snowmelt lost for the recharge of groundwater aquifers, the contribution of glacier runoff and seasonal snowmelt to mean annual flow (MAF).

Map from the report showing the boundaries of the study basins (red line), state borders (light yellow line) and snow-covered high-altitude belts where glaciers are located (white spots)

The authors have used Glacier mass budget-based methods and hydrograph separation techniques which they stated as suitable for basin-scale assessments instead of the temperature-index methods. They say that application of these two methods in semi-distributed models can give the highest currently possible accuracy of +30%. The authors opine that many of the studies done previously had confused between the ‘snowmelt’ and ‘glacier-melt’ because these studies have not dealt with terminologies and methodologies in detail. The report states that there is a scarcity of glacier runoff estimates in peer-reviewed papers, “An analysis of publications on modeling runoff from large- and medium-scale glaciated catchments….. indicates that not many of these dealt with modeling glacier runoff per se. Even fewer report their evaluations of glacier runoff separately from snowmelt, if at all.”

For the three of the six river basins studies and which flow through India, i.e. Indus, Ganges and Brahmaputra the total annual glacier runoff for the period of 1961-1990 was 41 km³,16 km³and 17 km³respectively. But in the recent periods of 2001-2010, total glacier runoff was reduced to 36 km³, 15 km³ and 16 km³respectively for the three basins, see Table 1 for details.

It is clear from the table that while Indus and Brahmaputra basins have similar percentage of area under glaciers and snowmelt, the reduction in the glacier and snow cover area are more pronounced in Indus basin. Besides, in all the three basins the reduction in glacier area is more pronounced that the snow cover area. However, the contribution of glacier melt and also snow melt to run-off is much higher in Indus basin compared to Brahmaputra basin, showing the greater role of precipitation in Brahmaputra basin. Within the Indus basin even though seasonal snow covers 28% of the total area, much than the 2.6% occupied by glaciers during 1961-90, the contribution of two sources to Mean Annual Flow is almost same. But a question arises, has the contribution of glacier melt to the runoff increased in any of the basins in the recent decade? The answer is surprisingly, no.

Table 1: Recent changes in the glaciers and seasonal snow and their contributions to MAF

Basin	Part of basin area(%) covered by		Contribution to MAF (%)
	Glaciers	Seasonal Snow	Glacier runoff	Seasonal Snowmelt
1961-1990
INDUS	2.6	28	18	19
GANGES	1.2	6	4	2
BRAHMAPUTRA	2.7	27	2	2
2001 -2010
INDUS	1.8	25	15	16
GANGES	0.9	6	3	1
BRAHMAPUTRA	2.2	26	2	2

For the Ganges basin, the report says that heavy summer precipitation almost solely determines MAF volume for the basin. Maximum seasonal snow area in the Ganges basin makes just 6% of the entire basin area. Similar situation were reported for the Brahmaputra basin, where the lower parts of the basin i.e. Southeastern Tibet and Eastern Himalayas where nearly 75% of the basin’s glaciers are located, witness heavy summer monsoon rains. Regarding Indus basin the report says, “Precipitation in the IndusBasin is more evenly distributed between the seasons, but is highly variable spatially – similar to Brahmaputra and Amu Darya, where annual precipitation in some catchments is tenfold (3,000 mm) of that in the other glacier-covered parts of the basin (300 mm).”

Reviewing already published documents the report states “it appears that the research in High Asia is concerned much more with CC impacts than with objects of the impact. Yet, understanding of the expected basin-scale changes in glacier runoff in response to climate change remains largely unclear.”

The report does an analysis of assessments done on impact of climate change on water availability in Himalayas and concludes that many assessments rely on poorly verified sources. The report refers to the statement made by Cruz et al. (2007) “The current trends of glacier-melts suggest that the Ganga, Indus, Brahmaputra and other rivers that criss-cross the northern Indian plain could likely become seasonal rivers in the near future as a consequence of climate change…,” This statement was admitted as a typing error after publication but even then this has been reiterated as an apocalyptic vision in NGO reports.

Using the Table 2 given below, the report states that glacier contribution is a minor item in the annual river water budgets in the Ganges and Brahmaputra basins. The report says “The impact of climate change was found to be more prominent on seasonal rather than annual water availability.” It is clear from the table that, in the recent decades non-renewable component in all three basins have gone up while renewable and total volume of water from glacier melt have come down. It is also noteworthy that, even though Brahmaputra basin has more area under glacier cover than the Ganges basin (see Table 1), the volume of water from non renewable glacier flow was more in both periods in the Ganges basin. Besides, the percentage of increase in nonrenewable glacier runoff components during 2001-10 is highest among all three basins, signifying that glaciers are melting fastest in Ganga basin.

Table 2: Contribution of renewable and non-renewable components to glacial runoff

Basin	Glacier runoff components		Total Glacier runoff (km³)	Total Glacier runoff contribution to MAF (%)
Basin	Renewable (km³)	Nonrenewable (km³)	Total Glacier runoff (km³)	Total Glacier runoff contribution to MAF (%)
1961-1990
INDUS	33.0	8.14	41.2	18
GANGES	11.0	4.74	15.7	4
BRAHMAPUTRA	12.7	4.29	17.0	2
2001 -2010
INDUS	24.5	11.62	36.1	15
GANGES	8.1	6.95	15.0	3
BRAHMAPUTRA	10.6	5.05	15.7	2

The reports also states, “Glaciers and seasonal snow in CC-impact assessments should be perceived as natural water reservoirs with gradually diminishing storage and flow regulation capacity, both on intra-annual and inter-annual scale. Potential changes of precipitation regime coupled with effects of temperature rise on evapo-transpiration will impact future hydrological regimes of the major rivers much more significantly, affecting both MAF and flow seasonality.”

The authors of this report clear some fog around climate change and Himalayan glacier system and snow-melt. One lacuna of the report is that even though the report discusses glacier run-off it makes no mentions of glacier lakes and glacier lakes induced floods. There are several incidents of glacier lake induced floods happening in the basins discussed. There is evidence to show that in the recent flood devastation in Uttarakhand in India glacial lakes played significant role.
