UTTARAKHAND: 

Constructing new dams will hinder mission to clean Ganga, says Uma Bharti Flagging her concerns against the major culprit (hydro-power projects), the Union water resources minister Uma Bharti has asked different ministries including environment and power to take a cautious approach while allowing construction of any new dam on the river. Her ministry is particularly against the six contentious hydro power projects in Uttarakhand which, it thinks, would severely affect the e-flow of the Ganga. Environmentalists had already pitched for scrapping of such projects that they believe may lead to another June, 2013-like disaster in the region.

HIMACHAL: Himachal Pradesh engineers blames untrained engineers and human errors responsible for growing numbers of hydro power project mishaps (15 June 2015) HP engineers say that the board was suffering these losses as they lacked the trained engineers. The limited staff is under pressure to perform technical duties and pressure mount on them as the government was not serious about filling the posts, said Lokesh Thakur, general secretary, HP Power Engineers’ Association, expressing anguish over the death of three engineers, two of whom worked in the HPSEBL.http://www.tribuneindia.com/news/himachal/lack-of-trained-engineers-to-blame/94204.html Continue reading “Dams, Rivers & People: June 22, 2015” →

“Right now, hydel is almost stalled”: Piyush Goyal (18 May 2015)

Union Power Minister makes some candid comments on Hydro: “Right now, hydel is almost stalled. We have Teesta stuck for various reasons. Subansiri, Maheshwar, Lower Subansiri, all of them have different challenges. Small hydros are facing challenges of transmission, they are facing challenges of local area problems. So, by and by, the hydro sector will need a more holistic thinking. The courts have also taken up certain matters, particularly in Uttarakhand, post the tragedy (of floods in 2013). There is the mission of Ganga to ensure that there is a reasonable flow—Aviral Ganga, which we are committed to. We are working on all of these plans… For example, Subansiri had an issue where the local population had concerns. We immediately got an eight-member very, very high-level expert committee, including Central Water Commission, Central Electricity Authority, and experts from Assam. They are all working together to see the environmental impact, structural impact, riparian state impact and riverbed impact.

Malin Landslide Tragedy underlines the vulnerability of Western Ghats

In the tragedy at a tiny village of Malin in Ambegaon, Maharashtra, as per reports till now, around 40 houses are under huge debris created by a landslide that occurred early in the morning on the 30th July 2014. The death toll till now is reported to be 44 with 150-300 missing as per different estimates. Unfortunately, the chances of survival of the missing are dim as per the Chief of Rescue operations.

Let us look at some key factors at play here:

VERY HEAVY RAINFALL: This region is nestled in the Northern Western Ghats which receives heavy rainfall in the monsoons. The region was receiving particularly very heavy rainfall in the week between 25th to 31st July. SANDRP had posted an alert on this on SANDRP Facebook page (https://www.facebook.com/sandrp.in) on the night of 29th July.

Cumulative rainfall in the week as recorded by NASA’s (The National Aeronautics and Space Administration of US) TRMM (Tropical Rainfall Measuring Mission, see: http://trmm.gsfc.nasa.gov/publications_dir/instant_2.html) was more than 600 mm, most of it between 29th-30th July. In fact on the 29th July, the region including Malin was shown purple in 24 hr rainfall map, which signifies the highest range of rainfall, exceeding 175 mm.

The region is still experiencing heavy to very heavy rainfall as we write this on Aug 1, 2014.

It was surprising to read report from Down to Earth about “mere 4 mm rainfall in 24 hours” before the landslide, which is clearly not the case.

With changing climate, frequency of such high intensity rainfall events is predicted to increase, making these areas even more vulnerable to disasters like landslides.

Landslide Warning

Following the very heavy rainfall in the regions around Northern Western Ghats, extending till Gujarat, NASA’s TRMM had also highlighted this region to be strongly landslide prone on the 30thof July.

See NASA TRMM Landslide Prone Area Map on the 30th July 2014 below which highlights Bhimashankar and Malin region:

The dam connection:

The Malin village is approximately 1.5 kms from backwaters of the Dimbhe Dam, which is an irrigation project involving a big dam completed in 2000. On the 31st July, the dam held 44% of its live storage, that is about 156 MCM (Million Cubic Meters) of water. The link between water level fluctuations in dams and landslides in the rim of the reservoir and backwaters is well documented. Some geologists have also recorded increased landslides activity in areas surrounding Dimbhe Dam in the past. ( http://timesofindia.indiatimes.com/City/Mumbai/More-landslides-likely-in-5km-radius-of-Dimbhe-dam/articleshow/39314716.cms) Even if the dam was not overflowing when the tragedy occurred, it is well known that the dams can induce such landslides around the rim in view of standing water with fluctuating levels, change in drainage pattern and underground water flow pattern.

Key salient features of Dimbhe dam: Ht: 67.21 m; Lengh: 852 m;  Live Storage Capacity: 354 MCM (www.mahawrd.org); Reservoir Area: 1754.7 ha.

The role played by the dam and its operations on the geology of the region and its possible connection with the landslide needs to be investigated in depth.

Landslides are not entirely new for the region

The region has seen some landslides in the past (e.g. in 2006-7) according to Saili Palande Datar, an ecologist and historian with Kalpavriksh. According to Anand Kapoor of NGO Shashwat active for decades in the region, a landslide had occurred earlier than that, where some cattle were buried and people had to be rescued. In a massive landslide on July 23, 1989, in village Bhaja in Mawal about 60 km from Pune, 39 people were killed.

In the Western Ghats of Pune as well as Maharashtra, a number of landslide-related tragedies have happened. According to a resident of village Tikona Peth in the catchment of Pavana Dam in Mawal tehsil of Pune, a landslide took place in in her village July, 1994 after heavy rains. There were no casualties, four houses were demolished by huge rocks. In August 2004, one person died due to landslide in Male, near Pune, in 2004 again, a worker died due to landslide in work related to a tunnel for a lift irrigation scheme, in June 2005, 4 workers died due to landslide at a tunnel of Ghatghar hydroelectric project.

Role of large scale land modifications in the region

Indeed according to a landslide map developed by Dr. David Petley, International Expert on Hazards and Risks in the Department of Geography at Durham University, the entire region of Western ghats has experienced landslides.

Dr. Petley has also written about the Malin Landslide here: http://blogs.agu.org/landslideblog/2014/07/31/malin-landslide-1/.

Dr. Petley told SANDRP, “Large scale land use modification and deforestation is the issue here”. He further said: “I would hypothesise here that the very heavy rainfall was the trigger, thick weathered soil, the shape of the slope and poor management of development and of water. A proper investigation should be able to ascertain whether this is right, but such large-scale modification of the landscape should be resisted.”

11_08 2011 map
From Dr. David Petley: Landslide events where fatalities have occurred. We can see that Northern Western Ghats also features regularly in the map.

Landscape modifications around Bhimashankar

Bhimashankar region, the origin of river Bhima which is an important tributary of Krishna, is a high rainfall region with spectacular biodiversity. It is also home to Maharashtra’s state animal Malabar Giant Squirrel. The region is home to a vibrant tribal community which has seen several assaults on its way of life through the formation of the sanctuary, displacement caused by Dimbhe & other Dams, recent windmill projects, etc.,

In the recent years, some of the major landscape changes occurring in this region are through mechanised terracing of slopes for cultivation as well as developments related to windmill projects on mountain tops, which entail deforestation as well as road cutting on steep slopes. Although there are no windmill farms in Malin, such farms exist in the neighbouring Khed tehsil. Plans for such farms in Ambegaon are in the pipeline.

It needs to be understood that terracing for cultivation has been a traditional occupation of the tribals in this region, as in most of the Western Ghats. Not only is it an important livelihood support factor, but it has been limited by its scale, location and implementation due to its inherent manual nature. According to Anand Kapoor of Shashwat, tribals themselves do not prefer terraces made by JCBs and other machines as these are not entirely suitable for cultivation.

However, it is also a fact that now some government departments are using heavy machinery like JCBs in their bid to push terracing program. Unscientific mechanized terracing, which comes together with muck dumping, slope instability, affected drainage etc., can play a huge role in magnifying the impacts on a naturally vulnerable, high rainfall region.

In fact, a preliminary report by the Geological Survey of India (GSI) has singled out land flattening and terracing by heavy machinery as one of the primary causes for the tragedy. As per the preliminary report, a team of GSI experts noticed cracks where heavy soil erosion had occurred. The Deputy Director General of GSI has said that these cracks are a result of improper drainage system of rainwater. The flattening of land would have affected the water drainage resulting in the cracks. He says: “The slope of the hill was flattened almost halfway for agricultural purpose to such an extent that the hilltop had become unstable. The experts have also reported excessive deforestation disrupting the ecology of the hill. Added to this was the damage caused by use of heavy machinery over two years.” The Director General and Deputy Director General will be visiting the site on the 2nd and 3rd August for further analysis.

An independent credible review of the way the land levelling activities are going on under government policies and programs should be immediately instituted and till its report is available, use of heavy machines like JCB may be minimised.

Management of the region according to Western Ghats Expert Ecology Panel (WGEEP) Report and High Level Working Group Report (HLWG)

Both reports place Malin in Ecologically Sensitive Zone I and Ecologically Sensitive Area (ESA) respectively.

An ESZ I tag by the WGEEP report regulates a number of activities in the region, with participation of local communities. The report has specifically mentioned threat of landslides in this region.

While noting the impacts of windmills in the region surrounding Malin, WGEEP notes: “Apart from substantial forest destruction (including Forest Department estimates of about 28,000 trees being cut) via wide roads cutting huge swathes through Reserve Forest, the wind mill project has triggered large scale erosion and landslides through poor construction of roads with steep gradients, and all this rubble is ending up on fertile farmland and in reservoirs of tributaries of the Krishna.

The Forest Department is colluding with wind mill project operators in also illegally denying citizens access to these hills. Boards and check-posts have been put up by the company, falsely claiming to be authorized by the Forest Department. There are many traditional forest dwellers on these hills. Not only are their rights under the Forest Rights Act not being recognized, they are being illegally restrained in their movements on hills they have inhabited for centuries.”

If the WGEEP was accepted by the MoEF and state governments, this would have led to a more people-centred and ecologically-sound management of the Western Ghats region, but Maharashtra has been vehemently opposing WGEEP on the most unjustified grounds and the MoEF too has been busy downplaying the WGEEP.

While HLWG did include Malin village in its list of Ecologically sensitive Areas, however, this ESA tag did not mean much for the region it only regulates mining and red category industries. Most of the development activities that might threaten the region are not regulated by the HLWG. More importantly, HLWG has no role for the local communities in democratic decision making. There is also no mention of this region being landslide-prone in the HLWG, whereas the WGEEP specifically highlights this issue.

It is clear that HLWG is not much help for the region in avoiding tragedies like the Malin tragedy, but WGEEP report certainly would have helped.

Way forward

Northern Western Ghats which are characterized by heavy rainfall, rich biodiversity and predominant tribal population need more sensitive management approach than what it is subjected to right now. Although WGEEP had paved way for a more democratic, equitable and people-centred management of the region, the report was hidden, downplayed and finally rejected by the state as well as the central government. Episodes like Malin highlight the vulnerability and complex inter-linkages that affect the region which require a long term planning vision, integrating a number of components.

Despite this, several ill-conceived projects like townships, windmill farms, large dams and river linking projects like Damanganga-Pinjal and Paar Tapi Narmada are proposed in the region. Close to Bhimashankar region, Mumbai Metropolitan Regional Development Authority (MMRDA) as well as the Greater Mumbai Municipal Corporation are pushing more than 12 large dams. Some of these dams entail huge tunnels under the mountain ranges of Western Ghats. Despite the several risks and impacts, many of these massive dams may also escape scientific Impact Assessments or public hearings. These projects needs to be opposed and urgently dropped as there is little justification of the projects in view of huge number of options available in the cities for which these dams are proposed.

Similarly, Maharashtra Government has plans to build three huge hydropower dams in the Velhe and Mulshi region, which also falls in the Pune District. Velhe region has already seen slope instability and also falls in Seismic zone IV, making any such development highly risky there.

Let us hope that the heart-breaking tragedy at Malin is a wake-up call for all of us, paving way towards more sensitive,responsive, democratic and sustainable management of the Western Ghats. As a first step, the state and central government need to accept and implement the recommendations of the WGEEP immediately in Malin and for the entire Western Ghats.

Will this Ganga manthan help the River?

Uma Bharti at GM

The one day Ganga Manthan[1] organized by the National Mission for Clean Ganga on July 7, 2014 was described by Union Minister[2] Sushri Uma Bharti & Union Minister[3] Shri Nitin Gadkari as “Historical”. The Union Environment Minister, who has one of the most crucial role in achieving a rejuvenated Ganga, was supposed to be there, but could not come at any stage.

I attended the full day meeting with a lingering question: Will this help the river? Even some of the ardent skeptics said that Uma ji has emotional, spiritual and religious attachment with the cause of Ganga.

At the conclave attended by close to a thousand people, the story of how Ms. Bharti came back to the BJP party about a year back to work for the cause of Ganga, and how she was promised a year back that if their party came to power, Ganga will get a separate ministry and she its charge was narrated repeatedly by both Ms Bharti and Mr Gadkari at least twice. It was also stated that the government has the commitment, the will & all the money to make the Ganga clean (Nirmal) and perennial (aviral). There were  also repeated statements by both ministers about the officials being so committed to the cause of Ganga. These, in essence, were the basic positive assets of this government to achieve Ganga Rejuvenation.

While it was good to see large gathering involving various sections of the society, including many independent non government voices, missing were some key stakeholders: Ganga basin state governments, farmers groups, Ministry of Urban Development, fisher-folk groups, boats-people representatives. Another key constituency missing was Ministry of Agriculture, since agriculture is major user of water & irrigation and responsible for water diversion and at the same time major non point source polluter through use of chemicals and fertilizers.

Rejuvenation does not mean just nirmal and aviral But if the task is Rejuvenation of River Ganga, are these assets sufficient? What exactly does Rejuvenation of River Ganga mean? There were no answers to this question at the meeting. The government did not even seem bothered about these questions. Are Nirmal and Aviral Ganga sufficient objectives to achieve Rejuvenation of Ganga? The answer is clearly no, for, even a pipleline or canal carrying perennial flow of water can claim that distinction. A rejuvenated river will need much more than that, but the government has nothing else to offer for a rejuvenated river.

Even for Aviral Ganga, the government had absolutely nothing to offer. In the information package shared with the participants, the only thing relevant to Aviral Ganga was the extended summary of draft “Ganga River Basin Management Plan” being prepared by consortium of seven IITs in collaboration with some 11 other organisations. This is led by Dr Vinod Tare of IIT Kanpur. While standing with Dr Tare and Rajendra Singh of Tarun Bharat Sangh at the lunch, I said, the problem with Ganga is not of technology[4], but of governance. Despite being a proud IITian myself, I have no hesitation in saying that IITs do not have expertise in governance issues, so how can the IIT Consortium help in fix a governance problem? Having read the full Draft Plan of the IIT consortium, it only further strengthens the view that it was wrong decision of Jairam Ramesh to give this task to IIT Consortium.

Agenda for further destruction As a matter of fact, while this government has yet to take a step that will truly help rejuvenation of Ganga, they have declared their agenda that will possibly further destroy the river. This was clear on June 6, 2014, within ten days of new government taking over when a PIB press release[5] announced, “Shri Gadkari said it is proposed to conduct dredging to provide a width of 45 meters and for a three (3) meters draft (depth) to enable transport of passengers and goods between Varanasi and Hoogly on river Ganga in the first stage of its development and eleven terminals are proposed to be constructed along the banks. He said barrages are proposed to be constructed at every 100 Kms.” This was a shocking and arrogant announcement. There is nothing in public domain about this Rs 6000 crores plan, no details as to what exactly is planned, where the barrages are planned, why are they needed, what are their environmental impacts, what are the social impacts, what are the riverine impacts, what is the cost and benefits, who will pay the costs and who will reap the benefits, where is public consultation….there is absolutely nothing in public domain and here is a nine day old government declaring such massive plan! By July 7, 2014, the PIB Press Release declared that the depth will now by 5 meters and not three announced earlier. The PIB PR now said, “He (Mr Gadkari) said barrages are proposed to be constructed at every 100 Kms on the river. Shri Gadkari said his Ministry has sent a proposal in this regard to World Bank for the development of Allahabad- Haldia corridor.”

The minister possibly does not know that there is just one barrage on the Allahabad-Haldia 1500 km long stretch, namely the Farakka barrage and Bangladesh had threatened India to take the matter about building this barrage to the UN! Moreover, that barrage, everyone accepts, has not even achieved the basic objective it was supposed to achieve, namely navigability of Kolkata port, but has had many other severe impacts.

Nitin Gadkari at GM

At Ganga Manthan, Mr Gadkari dropped a bombshell[6] when he said this plan is already in advanced stage of appraisal with the World Bank! He said the government hopes to get Rs 4000 crores from the World Bank!! The World Bank has zero track record in achieving any clean river anywhere in the world, after spending billions of dollars every year. In India itself it stands guilty of destroying many rivers. A more inauspicious start to the Ganga Manthan possibly could not have been possible. At the Ganga Manthan itself, there was opposition to this plan, as The Hindu[7] has reported.But Ms Uma Bharti finds nothing amiss about this as was clear by her answers at the press conference. But what about at least some semblance of participatory democracy?

Business as usual at NMCG and NGBRA will not help In reality, this is not all. While this Manthan for Ganga Rejuvenation is happening, the NMCG and NGBRA[8] (National Ganga River Basin Authority) go on with their work in business as usual fashion. So in Varanasi, the Uttar Pradesh Jal Nigam is going about its task of floating and examining the bids for five-part sewer laying and Sewage Treatment Plants with the help of JICA money. In Kanpur, the effort to divert several streams to Pandu is going on. In Allahabad, “the draft final ESAMP sewerage works for sewerage districts” A & C could be found on the NGBRA website. In Patna, the World Bank is funding the sewerage projects of Pahari in Patna & river front development and the draft social and environmental impact assessments could be found on NGBRA website. All of this (except the Varanasi packages, which are funded by Japanese aid agency) is going on under USD 1 Billion World Bank Funded NBGRA project.

So the business as usual that is going on for 40 years is now going to help rejuvenate Ganga!

The NMCG announced that the Manthan, a “National Dialogue on Ganga”, was supposed “to facilitate interaction with various stakeholders”, “to discuss the issues & solutions to the task of Ganga Rejuvenation”, “to prepare road map for preparation of a comprehensive plan”. The website said the Ganga is “holiest of Rivers”, “purifier of mortal beings” & “living godess”, but now “seriously polluted” and in “extreme environmental stress”.

Where is the dialogue? However, the way the meeting was organized, there was essentially no dialogue. After the inaugural plenary session, the participants were divided among four groups: 1. spiritual leaders, 2. environmentalists, NGOs, water conservationists, 3. scientists, academicians and technocrats, and administrators; 4. public representatives.

I went to the second group and there, when someone pointedly asked, if there is any representative of the government present, there was no response! In fact it was positively shocking that the first panel member that spoke in this group was Dr Arun Kumar of AHEC (Alternate Hydro Energy Centre) whose work on Ganga basin cumulative impact assessment is so discredited that even the official agencies like the Expert Appraisal Committee of MoEF, the Inter-ministerial Group on Ganga, the Expert Body appointed by the Supreme Court after the June 2013 flood disaster and the Supreme Court itself has criticized it or found it unreliable. NMCG has discredited itself by appointing such a person to give an overview of achievement of Ganga Action Plans.

GM stage

Ms Bharti apologized in the beginning for hurriedly-called meeting. But the least she could have ensured was a credible process that will ensure that the officials have to show application of mind to the various suggestions received and conduct of the meeting in credible and confidence inspiring way. But the meeting did not inspire confidence that there will be any credible process that will ensure that there is application of mind to the various inputs given. Many of the participants did not have any opportunity to speak.

Recommendations for the government on Ganga

1. Make an honest effort to learn from the past. Why have the efforts of last 40 years since the passage of Water Pollution Act 1974 not helped Ganga? Similarly why did the GAP I, NRCP, GAP II, NGBRA not helped make the Ganga clean (nirmal) or perennial (aviral)?

2. Understand & recognise that Ganga is a river and what are the essential characteristics of a Ganga that it needs to rejuvenate it as a river. At Ganga Manthan, in post lunch session in the room where the fourth group for public representatives was sitting, I was sitting next to an official of Ministry of Water Resources and I casually asked him does the ministry of water resources understand what is a river? He first said yes, but when I said you are only dealing with water and nowhere in your work have we seen any value for rivers, he said ok, but we can do it in collaboration with MoEF. The trouble is, even MoEF does not understand rivers. [It was also strange to see in this session Mr Madhav Chitale (former Water Resources Secretary) describing Tennessee Valley Authority of 1933 as an effort to clean the river! Such misrepresentation going unchallenged was shocking.] It should be remembered that it is this ministry of water resources through which Sushri Uma Bharti has to achieve a rejuvenated Ganga!

3. Ganga is not 2525 km long river: We kept hearing this sentence that Ganga is 2525 km length of river and Mr Bhurelal in fact said we need to limit ourselves to discussing how to make this stretch clean. The trouble is, if the tributaries are not healthy rivers, how can the main stem of Ganga be rejuvenated? As Manoj Misra of Yamuna Jiye Abhiyaan said, Ganga is not 2525 km, but much more than 25000 km including all the tributaries, as Yamuna is not 1400 km long but 13470 km long including all the tributaries.

4. Ganga in Mountains: Learn the lessons from Uttarakhand disaster, that affected the headwaters of the Ganga river. The Expert body constituted by the MoEF under Dr Ravi Chopra has a lot to say there. Revisit all the existing, under construction and planned projects in the whole basin.

5. Farakka barrage: It is well known that the barrage did not serve the basic purpose it was created for, namely making the Kolkata port navigable. But it has created such havoc in upstream and downstream for millions of people that some of the Bihar MPs of previous Lok Sabhas talked about decommissioning of the barrage in the debate on Ganga. But this government wants to make many more barrages! First do a post facto assessment of the Farakka barrage and its current costs, benefits and risks.

6. Formulate an Urban Water Policy: The footprint of the urban areas on the rivers is increasing in multiple ways, but we have no urban water policy. Some key elements that such a policy will include: Reducing transmission & Distribution losses, water audit from RWA upwards, Rainwater harvesting, decentralised and eco-friendly ways of sewage treatment and recycle, groundwater recharge and bottom up management, demand side management, protection of local water bodies, protection of riverbeds, floodplains and forest areas & democratisation of the Urban water utilities.  As the working report for the 12th Five Year Plan on Urban water said, no Urban areas should be allowed to have external water till they exhaust their local potential, including recycling of the treated  sewage and other demand side and supply side options. The footprint of the urban areas will increase exponentially if we do not urgently on this front.

7. Agriculture is the biggest user of water and our government encourages use of chemicals and pesticides in agriculture. Most of these chemicals end up in water bodies including rivers. If we do not want our rivers to be dumping grounds for these chemicals, the government should encourage organic farming. Similarly, in stead of encouraging water intensive cropping patterns and methods, government needs to encourage low water use crops and methods like System of Rice Intensification (SRI). SRI is applicable for many crops and can reduce water need by upto 50% and yet increase yields and incomes of farmers. But the government has shown no interest in encouraging SRI. Such methods can free up a lot of water for the river. Similarly, under the influence of powerful sugar lobby, we are producing more sugarcane and sugar than we need and than we are exporting the same at subsidized rates! So essentially we are exporting water at huge subsidized rates, that too from Ganga, but we have no water for the river!

8. Irrigation is the biggest user of water. At Bhimgoda, Bijnor and Narora barrages, we are diverting almost all the water in the river for irrigation. But we have no water for the river. If we change our water resources development and agriculture policies, it is possible to restrict these diversions to 50% and release the rest for the river. We need to review all this.

9. The IIT consortium report is seriously flawed and is not likely to help the river.

10. We need to define the path of the riverbed or right of way for the river, based on its need to carry 100 year flood and silt. In absence of such a defined space for the river, there are a lot of encroachments. There is also no river regulation law to regulate this riverways land. This is urgently required.

11. Our Pollution Control Boards and related mechanism is not known to have achieved a single clean river or nala in 40 years of their existence, anywhere in the country. This is because of the completely non transparent, unaccountable, non participatory and exclusive bodies, where people whose lives are affected by the pollution have no role. A complete revamp of this is required to make its management inclusive from block level upwards, and answerable to the local people through clearly defined management system.

12. One of the major reason for the failure of the GAP, NRCP and NGBRA is that their functioning is top down, with absolutely no clearly defined norms for transparency, accountability, participation and inclusive management. Unless we completely change this, no amount of money, no amount of technology, no amount of infrastructure or institutions is going to help the Ganga. We need management system for every STP, every freshwater plant, every city and town, every 3-5 km of the river, every tributary and so on. At least 50% members of the management committees for each of them should be from outside the government, including community members. The people whose lives and livelihoods depend on river including fisherfolk, boatspeople, river bed cultivators, local sand miners, communities depending on river for different water needs have to be represented in such management system. That will also create an ownership in river rejuvenation effort. This is also applicable to urban areas and all the tributaries.

13. This is also true for our environmental governance of dams, hydropower projects, flood control projects, water supply projects, and so on. Today there is no credible environmental management at planning, appraisal, construction, operation or decommissioning stage.

14. River of course needs water. Urgently. Chart out a road map to achieve 50% of freshwater releases from all dams and barrages in two years. Also no sewage water or effluents entering the river in two years.

In the concluding plenary, after listening to the reports from four groups (there were a lot of positive and useful suggestions there), Ms Uma Bharti and Mr Gadkari said that they won’t make any announcement today but they will ensure that the good suggestions that have come will be given to the decision-makers who will create a road map. This is very vague and unconvincing process with no credible transparency. The least the ministers could have assured is a confidence-inspiring process that would transparently ensure that the decision makers have applied their minds to the suggestions. But even that was not promised.

Despite this seemingly gloomy outcome, considering that the NMCG has invited[9] suggestions even after the meeting, I am going to send this blog link to them and wait for their response! Ganga definitely needs a lot of sewa from all of us if the river is to have any better future.

How do dams affect a river?

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.

river

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.

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.

from : lakeconesteenaturepark.com

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!

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.

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!

Ganga · Hydropower

What do Rivers have to do with Silt??

Rivers are again in the news, though so far only for symptomatic reasons. The new government at the centre has renamed the charge of water resources minister to Minister of Water Resources, River Development and Ganga Rejuvenation. There is fundamental contradiction within this name plate and we have in fact yet to see this nameplate.

There is also a lot of discussion about rejuvenation of Ganga, with the Prime Minister promising the people of Varanasi Parliamentary constituency that he will rejuvenate Ganga.  There is no clarity about how he plans to go about in achieving that. His claim during elections that Gujarat Government’s Sabarmati Riverfront Development provides a model for this is clearly a non-starter. Sabarmati has water only in 10.4 km of the river stretch that flows through Ahmedabad. If you go upstream of this stretch, you will find a dry river in most non-monsoon months and if you go downstream, you will find a river more polluted than Yamuna in Delhi. And even the water that one sees in this 10.4 km stretch is not the water from Sabarmati river basin, but is taken from Narmada River via Sardar Sarovar Canal! Pertinently, Ahmedabad or Sabaramati has no right over that water: the Sardar Sarovar Project has been built and justified in the name of Gujarat’s drought-prone areas like Kutch and Saurashtra.

The nameplate-changing business also extended to Union Ministry of Environment and Forests, its name changed to Union Ministry of Environment, Forests and Climate Change, though here again the new nameplate is yet to be seen. Unfortunately, all the noises that we have heard so far from this front seem to give primacy to growth rather than environment or forests or climate change! The new environment minister has yet to say anything about river protection, but he is already talking about river linking!

So is there a hope for rivers in this new establishment, going beyond the symbolic name changes? Here one is reminded of a meeting, where one of us (HT) was invited a few months before the elections, to discuss the state and fate of Yamuna River in Delhi. When HT started speaking, he started by asking what is a river? Is it just a source of water as engineers see it? Following a sudden change in program, Sushri Uma Bharati was the chief speaker at the meeting and when it was her turn to speak , she actually tried to understand that question and tried to find an answer to it: what is a river? Her becoming the Union Water Resources Minister also raises hopes since she had been campaigning for Aviral Dhara (Continuous flow) of the Ganga and against building of dams and hydropower projects in Uttarakhand. We hope that she will realize that impact of dams and hydropower projects on rivers is similar, if not same everywhere.

Ms Bharati is also minister of river development and Ganga Rejuvenation. The question, What is a river? becomes even more relevant in that context. A river is possibly the most complex ecological entity and we still do not understand fully how to define a river. But here we would like to highlight that river is a lifeblood of the ecology and carries so much more than water. One of the key elements that river carries is silt or sediment (although there is a slight difference between the two, we will use it interchangeably here).

The rivers carry silt from various points in their journey from the hills, to the deltas where most major rivers meet the sea. In this journey, the type, quantity, movement of silt varies with place and time. The silt comes in various forms, from suspended matter to fine silt to coarser sand. It is the transfer of silt from upper catchments to the plains that helps build fertile and alluvial flood plains like the Indo Gangetic plains.

The flow of sediment through rivers to the delta also protects the deltas, which are very highly productive & biodiversity rich ecosystems, population centers and agriculturally fertile areas. Deltas are constantly facing the threat of erosion by sea. In this fight against erosion by sea, the sediment brought by the rivers helps the deltas in a major way. Sediment flow to delta becomes even more important when sea levels are rising in changing climate.

However, when we build dams, hydropower projects and diversion structures on the rivers, we completely change the silt flow pattern in the river. The dams arrest the silt and hydropower projects and release silt free water in the downstream. The erosion capacity of the silt free water is greater, and the additional erosion they cause in the immediate downstream may not compensate for the silt trapped in the dams. The run of the river hydropower projects may release silt annually or more frequently and also on daily basis from desilting chambers, but the pattern of transport of the silt again completely changes. Moreover the dams and diversions completely change the character of flood-flow in the downstream area, when it is established that floods are the most important sediment-transporting events. All these changes have huge impacts in the riverbeds, in the floodplains and in the deltas. And most worryingly, we do not understand these impacts completely as yet.

It is only recently that scientists have started work that provides a glimpse of impacts this changing silt flow is causing. For example, our deltas are literally shrinking and sinking, and several independent scientific studies are telling us that dams must take major, about three-fourths of the blame. About 80% of the sediment that rivers bring can be trapped by the dams and this means that dams are annually trapping about 40 billion cubic meter of sediment globally. That is more than five Sardar Sarovar Dams every year! In India, our estimate earlier showed that large dams are trapping at least 2 BCM of silt every year, this figure is likely to have gone up now.

Not all the sediment trapped in the dams would reach the deltas, a significant part would have been left on the floodplains and in the river channels. And sediment trapped by dams is one of the many reasons behind sinking of deltas. However, scientists are estimating that already deltas have been deprived of at least 73 BCM of sediment by the dams. In South Asia, during the past century, Indus delta sediments have been reduced by 94 percent, Ganga-Brahmaputra delta sediments by 30 percent, and Narmada delta sediments by 95 percent.

In 2007-08, the Ganges, Mekong, Irrawaddy and many other rivers flooded with more than 100,000 lives lost and more than a million displaced. Most of the deltas that were flooded did not receive a significant input of sediment. These major flood events lead to sediment trapping behind mega dams.

The direct impacts of delta subsidence and effective seas level rise include inundation of coastal areas, saltwater intrusion into coastal aquifers, increased rates of coastal erosion, an increased exposure to storm surges, in addition to the threats to food security, livelihood security, water security for millions and a huge loss of biodiversity. These threats impact hundreds of millions of people who inhabit the delta regions as well as the ecologically sensitive and important coastal wetland and mangrove forests.

As Prof. James P Syvitski, the Chair of the International Geosphere-Biosphere Programme, told SANDRP, “We must learn to do better.” However, decisions surrounding dams in most regions of the world are not even assessing the impacts on deltas. Ignoring sediments when building and operating dams comes at a huge price. Someone else is paying that price right now and this price is steeply increasing. For full SANDRP report on this issue, write to us or see https://sandrp.in/Shrinking_and_sinking_delta_major_role_of_Dams_May_2014.pdf

This article provides a glimpse of the role that rivers play in sediment transport. It goes to show how little we know about the role played by rivers in our lives. We hope we have much richer debate around the role of rivers in our lives in days to come.

Dams

Ganga in Peril: Building more barrages will finish it off

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.
