A new study of available scientific publications on impact of Hydropower projects on biodiversity provides a thorough review of the subject. The review does not directly give a call not to construct more such destructive projects. But it is useful for anyone concerned about the impact of dam projects on rivers.

The study discusses the impacts of hydropower projects on both aquatic and semi-aquatic species in riverine ecosystem and cumulative impacts spatially and temporally across river basins. Dams disrupt longitudinal connectivity and act as physical barriers in upstream-downstream movement of species. Upstream of dam, there is static water environment rather than flowing river environment. In the downstream, the hydropower projects adversely affect the water flow, sediment flow, thermal regimes, affecting water quality and environmental cues for the fish movement. All these also affect the floodplains both upstream and downstream.

A number of reports listed below this week throw fresh light on functioning of global water cycle, some of the findings should be seriously worrying. The studies show how the countries across the globe have water connections that go far beyond shared rivers, lakes and seas. And how these components of global water cycles are not only changing, but are under unprecedented stress and could take the global water cycles off balance.

Another study about atmospheric rivers that provides some of the largest high intensity rainfalls show that these rivers are shifting, which can have far reaching consequences for large sub-tropical areas, polar areas and others. For understanding their implications, more studies particularly focusing on shifting El Nino and La Nina streams are required.

DRP NB 14×24: Big Dams, Long distance water will not solve Urban Water Crisis

October 14, 2024October 14, 2024 SANDRPLeave a comment

In a pointed article this week, Sachin Tiwale rightly writes that Mumbai does not need more dams, but needs to fix the distribution of more than enough water that it gets currently. Same is the case with highly capital and energy intensive 5^th stage of Cauvery Water Supply being inaugurated on Oct 16 by the Karnataka Chief Minister and Deputy CM for Bangalore, advertised through full page advertisements today (Oct 14) in newspapers in Bangalore.

What the India’s cities need is to exhaust the potential of local water resources, including rain water, local water bodies including rivers, groundwater recharge, recycle and reuse of treated sewage and also demand side measures, including fixing the distribution and reducing transmission and distribution losses. All of this needs attention through a National Urban Water Policy that will also fix the Urban Water Governance.

It is increasingly clear that Large Dams across the world are facing increasing challenge due to climate change. In recent years, we have already seen serious dam disasters in Australia, Brazil, Canada, India, Kenya, Libya, Nepal, Nigeria, Poland, Spain, Sudan and USA to name just a few.

All these are related to extreme rainfall events, which are going to only increase in intensity, frequency and spread. It is interesting that hydro industry platform has come out with this report highlighting this issue this week.

For a country like India, the third large dam builder in the world, this challenge is going to be even more daunting as we have been seeing the increasing number of dams related disasters in last few years. As we remember the Teesta 3 dam disaster a year ago, the nature and dimension of this challenge becomes even starker. This is also exemplified by the fact that the dam safety panel report about this disaster is not even out in public domain. And even now new theories are being proposed about what happened during the disaster.

DRP NB 300924: Focus on River Studies

September 30, 2024 SANDRPLeave a comment

Rivers are the most important ecosystems (eco here includes ecology and economy) and yet possibly least studied entities. Some news below this week about some river studies brings the focus on need to take up many more river related studies.

Most important aspect of river related studies is the need for credible, independent studies, not influenced by the needs of the governments. Otherwise, the government is likely to not only influence the study, but also decide not to make it public as they did in case of the studies related to Joshimath town and role of Chamoli disaster.

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

April 3, 2023April 4, 2023 SANDRPLeave a comment

(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 News Bulletin 20 Dec 2021: Judiciary fails the environment AGAIN

December 20, 2021December 22, 2021 SANDRP3 Comments

By allowing the Char Dham Highway to go ahead, putting aside all the environment, safety, disaster vulnerability and even norms and affidavits of the Ministry of Highways and the Defence Ministry, as well as the report of the expert panel set up by the apex court, the Judiciary has again failed the Environment, among other things. This is contrary to the generally held belief that Judiciary stands up for the cause of the environment. That belief has no real basis, as can be seen again. This is also failure of the governance, experts and environmental groups, besides also the failure of the media too.

DRP News Bulletin 20 Jan 2020: India urgently needs national urban water policy

January 20, 2020February 4, 2020 SANDRP1 Comment

A large number of stories this week remind us that India urgently needs national urban water policy.

The water footprint of urban areas is gradually on the rise. The cities have several problems with management including destruction of water sources, groundwater exploitation, poor performance in treating and recycling the polluted water, pollution and encroachment on water bodies etc. To fulfil their growing demands new dams, barrages and check dams are being planned, proposed and built on the rivers in faraway places, which is in turn displacing and depriving the local people of equitable water share.

Even before onset of summer, the Army in Sagar district have started patrolling Chitora dam to prevent water thefts (denying farmers to take dam water for irrigation).

DRP NB 6 Jan 2020: When will Inland Fisheries get its due in decisions about rivers & other water bodies?

January 6, 2020January 6, 2020 SANDRPLeave a comment

In shocking instance, the Govt of India has provided just 17 days for commenting (Submission of Comments of NPSSFW _Inland_ on the Draft NFDB Bill 2019_ with rejoinder) on Draft National Policy for Inland Fisheries (Draft_NFDB_Bill_2019). As can be seen from the comments by National Platform for Small Scale Fish Workers (Inland) on the draft policy, the draft policy has major lacunae. The most glaring one is the complete lack of any role for the Inland fisher people in the decision making about rivers and other water bodies in India. Every dam and hydropower project has adverse impact on the fishes and fisher people, but the impact assessment reports rarely if ever even mention such impacts, leave aside question of any rehabilitation for them or even compensating them for the losses.

This is in complete contrast to the situation in US and a number of other countries where fish and fisher people have a much bigger role. Even as millions of people depend on Inland fisheries in India, we do not have even reliable census of the people who depend on Inland fisheries. One had hoped that in new year, the situation would improve, but going by the Draft Policy, there is not too much hope on that front. The least the govt can do is to immediately accept the suggestions of the National Platform and circulate the draft in all major languages and provide three months for comment period and institute a confidence inspiring process of including such comments.

DRP News Bulletin 6 August 2018 (2018 is Deficient Monsoon for Lakhs of Farmers)

August 6, 2018August 6, 2018 SANDRPLeave a comment

(Feature Image: IMD Sub-Division wise Weekly Rainfall Map 26 July – 1 Aug. 2018)

Amid news of monsoon being normal, farmers in several parts in the country have started facing irrigation water problems affecting sowing of Kharif crops. Apart from, insufficient rainfall, mismanagement of water resources is turning the situation grim for them.

As per reports, water levels in Bhakra and Pong dams in Himachal has plunged to lowest in decades. As a result dam authority has issued advisory to lakhs of farmers in Haryana, Punjab and Rajasthan to use water judiciously. Some official also said that the beneficiary states lacks efficient water management practices which is making the situation tough for them.

The Sri Ram Sagar Project in Telangana has no irrigation water. As per state water minister, a Rs. 1100 crore work was going on to renovate the dam. Meanwhile farmers of about 24 villages have started protest demanding irrigation water form SRSP for their standing crops. Given the tense situation, the State Govt has deployed heavy police forces to control farmers agitation.

At the same time, farmers in North Gujarat farmers have lost 40% of sown crops particularly in Ahmedabad, Morbi and Surendranagar. Non availability of Narmada waters have added to the problems. It is worth to mention that mismanagement of water during past four months in Narmada dam by the authority, has worsened the plight of farmers. Meanwhile, there are reports of furious Surendranagar farmers themselves opening the dam gates going against authority.

Similarly, lack of rainfall in Beed district which is part of Marathwada in Maharashtra has affected the rural population badly. In fact, the rainfall situation in a fourth of India, including Bihar and Uttar Pradesh, was in stark contrast to the rest of the country. Overall, the southwest monsoon in 2018 was only 2 % below normal by July, 27.

The southwest monsoon in Bihar was almost 40 % below normal till July 27 and the state was set to be formally declared ‘drought-hit’. It is worth to mention that the monsoon scenario seems less than reassuring, based on Skymet latest forecast and reading between the lines of IMD Aug. 3, press release.
