DRP NB 010523: Water bodies census welcome, but how reliable?

While the publication by the Union Jal Shakti Ministry of the first water body census of India is not only welcome but urgently required, the usefulness of the census findings will depend on the quality of the information in the report. Firstly, such a census should have been conducted in a bottom up way, starting from villages in rural areas and ward in urban areas. That way, the census findings would have not only been more reliable, but also the process would have helped create greater awareness about the water bodies and issues surrounding them.

In case of Karnataka, as the report below shows the survey by the Tank Conservation and Development Authority and Karnataka Public Land Corporation in 2021 showed the state had 40483 water bodies, whereas the Jal Shakti Ministry census of 2022 says the state has just 26994 water bodies, a huge 13489 less than the 2021 census. Clearly so many water bodies cannot disappear in a year. As some experts from Karnataka have asked, is the Jal Shakti Census a deliberate attempt to show that a much lower number of water bodies exist, allowing encroachers to go ahead to destroy water bodies not registered in the census?

DRP NB 030423: IRENA confirms bleak future of Large Hydro globally

(Feature Image: Graph showing annual growth in hydro power capacity in MW. Source: Rivers Without Boundaries, April 01, 2023)

The annual Renewable Statistics 2023 report from IRENA (International Renewable Energy Agency) says that globally, only 1.6% was added to the hydropower capacity in 2022, that too two thirds in non-democratic China. The capacity added in rest of the world outside China in 2022 was 7.3 GW, lowest figure in last 15 years. Similarly 99% of additional capacity added in pump storage projects in 2022 was in China. The report from IRENA also says that 97% of hydropower finance comes from public or government sources and private sector seems to have little enthusiasm for this sector. The projections for future painted in the report is no better. This is broadly in line with our lead story in DRP News Bulletin last week (dated March 27 2023) painting bleak future of large hydropower projects.

DRP NB 130223: El Nino set to endanger 2023 SW Monsoon rains

After four years (SW Monsoons of 2019 [110.4%], 2020 [108.74% compared to normal rainfall], 2021 [99.3% or almost normal rainfall], 2022 [106.5%]) of normal or surplus monsoon rainfall, SW Monsoon 2023 could face rainfall deficit and uncertainties as per US Govt weather agency NOAA and also India’s IMD. El Nino conditions are many times associated with poor monsoon rainfall in India. Since SW Monsoon provides more than 75% of total annual rainfall of India, this can be critical for India. The shift from particularly prolonged La Nina conditions to El Nino conditions should be a warning sign for India. IMD DG has said that the department will come out with an update on Feb 28, which should be sufficient advance notice to take necessary steps to tackle its possible impacts on upcoming Summer and SW Monsoon. We hope the government is ready to take the necessary steps to tackle any eventuality.

DRP News Bulletin 24 June 2019: Questions about Kaleshwaram as big as the project

June 21 seemed like a new day with all the national newspapers carrying full front page advertisements about Kaleshwaram project of Telanagana, advertised with more than usual share of superlatives: Lifeline of Telangana, record breaking projects, the world’s highest lift project completed in fasted time and so on. At three (Maharashtra – the upstream state- Andhra Pradesh – the downstream state and Telangana the project state) Chief Ministers and one governor gathered on the banks of Godavari river in Jayashankar Bhupalpally district to inaugurate a project that opposition mocked, saying it is just 20% completed.

But there were many serious unanswered questions and problems around the costliest irrigation project of India from a region and sector that is infamous for corruption. Water availability itself is in doubt, the impact assessments are hardly done even in name sake, public consultations non existent. Even statutory clearances are being questioned. If this is the best or even least cost option for the Telangana is not even debated, for a project that may need over 5000 MW of power for lifting the water to over half a km height. That too in a state where no district has below 500 mm rainfall.

India Rivers Studies 2017: Rivers Succumbing To Dams, Pollution & Climate Change

After reviewing status of India rivers, SANDRP presents an account of research, studies and important reports on erratic monsoon, climate change, floods which all are severely affecting the rivers, their aquatic life and livelihood of dependent communities.

Rivers and Monsoon

Number of rainy days falling across river basins in India The study has found that number of rainy days is falling across river basins in India and rainfall intensities are seen to be increasing. The analysis determined changes in heavy precipitation and peak flood for seven river basins in India—Krishna, Godavari, Mahanadi, Narmada, Cauvery, Sabarmati and Brahamani and Baitarani. For the study, data pertaining to daily flows for about 30 odd years and precipitation for 61 years (from 1951 to 2012) were analysed.

The analysis also said the rivers which flow from west to east direction (in India) have more rainy days compared to those which flow towards the west. The study also held that anthropogenic activities (construction of storage reservoirs, diversions, urbanization, land-use change, and soil and water conservation measures, among others) have probably affected the generation of peak floods in the rivers of India. http://www.livemint.com/Politics/c7v8oXmsMDHIldjDv9k6lK/Number-of-rainy-days-falling-across-river-basins-in-India-s.html (Live Mint, 27 April 2017)

Subject: Submission related to Chenab River and Lahaul Valley  in context of EC for 430 MW Reoli Dugli project

Dear Chairperson,

We have read reports that the expert appraisal committee (EAC) on river valley and hydel projects of the Ministry of Environment has decided “not to take any cognizance of representations” received by its members since such representations are ‘anti-development’. The article appearing in Indian Express on January 14, 2017 stated, “In its December 30 meeting, the committee concluded that once a project proposal reaches the EAC for appraisal, it has crossed the stage of public consultation and “the EAC should not go back in time, and should not reopen it, by entertaining unsubstantiated representations received from the people”.

Climate Change & Himalayan Glaciers: A News Round up

This year has witnessed erratic rainfall, increased snowfall, rising sea levels and other extreme weather conditions and the situation is not likely to improve in the coming months. Recent assessments have declared that this is the result of climate change, which we so conveniently blame for every untoward weather condition without properly addressing our own role in bringing it about or perhaps minimizing its effects. The climate is changing and the urgency to address this now is more than ever. Climate change acts as a catalyst and multiplies the threat we already face from certain environmental circumstances. The effects of climate change are being felt worldwide and global urgency is being expressed through various seminars and assessments being carried out by different international bodies like the IPCC (Intergovernmental Panel on Climate Change). Scientists have warned that extreme weather events will increase in intensity if climate change goes unchecked. Unchecked climatic change is also responsible for loss of life and property. According to the World Bank Report ‘Building Resilience: Integrating Climate and Disaster Risk into Development’, “from 1980 to 2012, disaster-related losses amounted to US$3,800 billion worldwide. Some 87% of these reported disasters (18,200 events), 74% of losses (US$2,800 billion) and 61% of lives lost (1.4 million in total) were caused by weather extremes (Munich Re 2013)[i].”

These weather extremes can cause and are in turn caused by changes in various water resources such as seas, lakes, rivers and glaciers. The Himalayas, spreading across over 2500 kms are the source of various life giving rivers in India and other parts of South Asia. The Ganga, Brahmaputra and the Indus, among the most important rivers for the South Asian region, originate in the Himalayan glaciers. The Himalayas have the highest concentration of glaciers outside the polar caps. These glaciers are natural stores and regulators of water in these rivers, which in turn support needs and livelihoods of millions of people, provide water for irrigation, domestic consumption and energy generation. Climate change is likely to result in smaller glaciers and less melt water. For rivers like the Indus, which gets almost half of its water from the melting of glaciers, this can lead to the endangering of the livelihood of millions of people living in low lying areas.

Even though such fears are being expressed by various groups of people, studies done by the ICIMOD in collaboration with Netherlands’ Utrecht University and research organization FutureWater, observe that the water levels in the Indus, Ganga and the Brahmaputra are likely to increase at least until 2050[ii]. This, they say, is due to an increase in melt-water in the Indus and an increase in precipitation in the Ganges and the Brahmaputra. But these projections, as even the scientists acknowledge, do not say anything about the future of these rivers. With retreating glaciers, what will the fate of rivers like the Indus be, which depend largely on melt-water, is still to be ascertained.

Soaring temperatures, melting glaciers A study prepared by the Uttarakhand government has predicted that the mean annual temperature (MAT) in the Himalayan region is likely to rise by up to 2 degree centigrade by 2030. It has also predicted a rise of 5-13% in rainfall in the next 2 decades. This was disclosed in the Rajya Sabha on 5th of August, 2013 by the then Science and Technology minister, S Jaipal Reddy[iii].

According to a report presented in the Second India Water Forum in 2013, melting of glaciers will lead to a reduction in the critical water supplies for the people of the Himalayas. The International Centre for Integrated Mountain Development (ICIMOD) predicted that Himalayan water flow from the glaciers to the basin would reduce by about 25-50% by the end of this century[iv]. The significant effects of this will be seen in the upper reaches. Taking the case of Ganga, it is seen that though its snow and ice melts contributes only about 1-5% of the water in the Ganga and its tributaries, this is only an annual averageiv. The percentage of melt water becomes higher in the months of March, April and May. This then becomes a very crucial amount of water in the rivers in those summer months where it cannot be recharged through rain.

This is also very important for the hydro projects downstream. Seasonal melt-water serves as the main source of power for an increasing number of hydroelectric dams on the rivers served by the glaciers. The amount of electricity generated depends on the amount of water flow in the river. Thus with changing river patterns in South Asia, the hydropower production will be disrupted. A 1% reduction in stream flow can reduce electricity output by roughly 3%[v]. The unreliable and potentially decreasing flow of water implies that whole hydropower development plans need a comprehensive rethink, also considering the increaed threat of flashfloods and related disasters in changing climate.

Another report by the ICIMOD has found that glacier runoff contributes majorly to river flow for about 2-4 months, mainly from early/mid-summer, till late summer/early fall and reaches its maximum in the Northern hemisphere in July-August. The total mass of the glaciers is much more than what is recharged every year, thus leading to smooth inter-annual flow variability and thus reducing risks of the late summer droughts in hot and dry summers. Climate Change, however, may lead to consistent mass loss in glaciers, hence reducing their inter-annual storage capacity[vi].

The report further reads:

The withdrawal of glaciers and seasonal snow covers as the transient storages for precipitation in certain areas implies first and foremost the loss of flow regulation capacity in basin’s headwaters… Combined effect of the reduction of glacier area and seasonal snow extent on the seasonality of flow from the alpine catchments will be characterized by an increase of the magnitude of the short-term flow variability, in particular, an increase of autumn and winter flow, shift of late spring-early summer peak to earlier dates and possible decrease of mid-late summer flow (assuming no changes in precipitation). Hydrological regimes will be gradually changing from glacio-nival to fluvial, i.e., dependent primarily on rainfall… The glacier runoff simulation results suggest that relative shares of renewable and nonrenewable components in total glacier runoff have undergone a remarkable change: the nonrenewable component increased from 16-30% of total glacier runoff in 1961-1990 to 26-46% in 2001-2010 in all the study basins. However, the increase of non-renewable runoff in none of the basins has been large enough to overweigh the decrease of the renewable component of glacier runoff due to overall reduction of the glacier-covered area.[vii]

According to another study co-authored by Anil Kulkarni, visiting scientist at the Divecha Centre for Climatic Change, entitled, The state and fate of Himalayan glaciers, the rate of loss of glacial mass in the Himalayan and Karakoram (H-K) region, has increased after roughly 1995. Rough estimates suggest that glaciers in the Indian Himalaya are losing mass at the rate of 16 Billion T per year[viii]. The loss in mass for many small glaciers located in low altitude range could be larger than the average suggests, being as high as 1 m per year. This is substantial loss considering mean depth of small glaciers could be between 30 and 50 mviii.  These small glaciers and ice fields are important source of water for many mountain communities. This source of water is and could be significantly influenced in near future and could affect sustainability of many mountain communities. There is today neither a mapping of such vulnerable communities, nor any plans to compensate them for the losses they are suffering and will suffer for no fault of theirs.

This loss of mass, especially if it comprises of non-renewable runoff, can also lead to further complications. According to geophysicist and seismologist, Geological Survey of India, Mr. O.P. Mishra, melting of glaciers due to increasing temperatures and high rainfall also add to the already existing complex of factors influencing earthquake activity in the Himalayan region[ix]. According to him, the ice sheet melting leads to the loosening of the litho static pressure (vertical pressure on the underlying crust)ix. As a glacier retreats and its weight eases, the earth could show a tendency to bounce back up in the form of a moderate or even a strong earthquake. According to him, there is a strong correlation between the retreat of ice sheets and increased seismic activityix. This increase in seismic activity can also lead to further melting of glaciers and a change in their behavior as it has the capacity to alter the axis of rotation, which can then lead to changes in surrounding areas.

According to a study conducted by the Chinese Academy of Sciences (CAS), the glaciers in the Tibetan plateau, which form the source of vital rivers such as the Brahmaputra, have shrunk by about 15%, which would mean about 8,000 square kms since 1980[x].

They also found that the perennial frozen earth in the plateau had decreased by 16% over the past 30 yearsviii. This does not present a favourable scenario for water security in the region and downstream areas of the Brahmaputra. According to scientists, this glacial retreat has accelerated since the 1990s and is making the plateau more vulnerable to the effects of climate change. This again means the plans for hydropower projects in North East India will need a review, but unfortunately, the Environmental and Social Impact Assessments of these projects are not even considering these factors and the MoEFCC’s (Ministry of Environment and Forests and Climate Change) Expert Appraisal Committee on River Valley Projects is not even taking these into consideration while appraising these projects in spite of repeated submissions on this by SANDRP.

The situation is similar in the case of the Gangotri glacier. Scientists at the GB Pant University of Himalayan Environment and Development have observed that the gangotri glacier is reducing in volume and size. The glacier is 30.2 km long and is the origin of the Bhagirathi, one of the main tributaries of the Ganga. This has retreated more than 1500 metres in the last 70 years. According to researchers, from the year 2000 onwards, the average rate of retreat of the glacier per year has been about 12-13 metres[xi].

Even while this is happening, there have not been any efforts to sensitize the scores of pilgrims who flock to Gangotri every year towards the condition the glacier is in, and how they can help in not letting it deteriorate further or at least in slowing down the process. They need to be made aware of the danger that the environment is faced with and should be encouraged to take steps towards its conservation. The state and union government also needs to ensure that local projects do not lead to worsening the situation. It is also the responsibility of the local people of the area to conserve what is important for them. They have to come out and take responsible action to ensure that they have a say in the plans made for their area.

The impact of glacier melting is felt in the upper reaches of the river and also in low-lying areas. For example, the Tawi river in Jammu has become shallow over time so much so that one does not need a boat to cross it anymore at certain locations and certain times. According to the retired director of operations M.M. Munshi, Geological Survey of India, “the glaciers and barrier lakes in the Jujdhar and Seojdhar ranges, which contribute a larger share of water to Tawi, have almost disappeared… water flow in all the rivers is declining… the perpetual snow line in Jammu and Kashmir has gone up to 16,000 feet from 13,000 feet in the last hundred years”[xii]. Such changes affect those who mainly rely on water for their livelihoods, i.e., farmers as also ground water recharge. It is not only the unavailability of water, but also the floods caused due to untimely or heavy rains. In such situations, which are recorded to be increasingly occurring in this region, people have to suffer the loss of land, livestock and thus even livelihood.

Such floods in the upper reaches by the headwaters can also be caused due to the flooding/breaking of glacial lakes. These glacial lakes can either already exist or even get formed in case the precipitation and/or glaciers melt increases. Global warming is seen as one of the key causal factors in their formation. According to recent reports, melting of glaciers is leading to the formation of small lakes in the high reaches of Himachal Pradesh. These lakes pose danger to the villages downstream. Out of the 249 glacial lakes in Himachal, 11 have been identified as having high potential for breach. Glaciers and ice-bodies cover a total of 2472.49 sq km (4.44%) of the total area of 55673 sq km in the state[xiii]. This is made worse by the uncertainty of rainfall and increasing frequency of higher intensity rainfall.

These kind of glacial lakes are forming in many areas in the Himalayas. Such lakes can also have loose moraines with them, which pose a greater threat to downstream areas as there could be a sudden breach of the moraine dams leading to flooding. One of the ways to prevent excessive harm to the people is if the rate of glacier melting can be studied with some degree of attentiveness, then alarm systems can be installed in areas downstream to warn the people in case of a Glacial Lake Outburst Flood (GLOF).

The monsoon is likely to become even more unpredictable in the coming years. Thus the threat to our environment from climate change is on the rise and it increases every day that we choose to ignore it. The government had set up the National Action Plan on Climate Change (NAPCC) in 2008 which was intended to serve as a road map on how India plans to combat climate change. There are various missions under the NAPCC amongst which are the National Water Mission and the National Mission for Sustaining the Himalayan Ecosystem, which has been constituted primarily to understand to what extent the glaciers are retreating and how the problem can be addressed. The government plans to review all the missions in 2017. However, as SANDRP publication “Review of NAPCC: There is little Hope here” showed, both content and process of formulation of the NAPCC had nothing to be hoped for particularly as far as vulnerable communities were concerned. A more detailed review of the National Water Mission in SANDRP’s 2012 publication “Water Sector Options for India in a Changing Climate” showed, the process, content and implementation of the National Water Mission is not going to bring any help to sustainable water resources development or to the vulnerable sections.

We have seen various so-called natural disasters happen since 2008, a very significant one of which was the Uttarakhand flood disaster of June 2013. The Uttarakhand government, at the end of last year, proposed a Rs 9,000 crore action plan to minimize the effects of climate change. Under this plan, it had allocated Rs 108 crore to be spent on water resources, like the treatment of catchment areas and flood control, etc. These measures just show the desperation of the government to show that something is being done in the namesake, even though it is not based on any scientific studies or participatory process. It seems to be the same way in which the Disaster Management cell was set up in Uttarakhand to try and manage any disaster that might strike the region, the campus of which was affected in the 2013 floods. The affected people have still not received sufficient help from the government. Even the basic minimum facility like the road that leads into Uttarkashi has not been constructed. The local people have to cross tracts of dusty and congested roads to reach from one place to the other when it has been over a year since disaster struck the town.

What we need is for the community to be involved at every stage from planning, impact assessments, decision making, implementation, operation and maintenance process and awareness creation in the areas which are most vulnerable. The current top-down approach that pushes business as usual situation will clearly not help.
