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.

Despite declaring Gangetic Dolphin a National Aquatic Animal in May 2010, launching of Project Dolphin in August 2020 and recognizing October 05 as National Dolphin Day since 2022, the key species indicating river health continues to face unnatural deaths and threats from various developmental activities. This overview highlights the incidents of suspicious death of precious mammal and looming threats on its habitat along with some noteworthy steps being taken by conservationists and governments to protect the endangered species.

DRP NB 07×24: Global Dam Safety Challenge in Changing Climate

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.

MoEF Committee Rejects the Adani Application and asks to apply afresh for Warasgaon-Warangi Project!

October 3, 2024October 3, 2024 SANDRP1 Comment

In a respite to forest dwelling communities, fragile biodiversity and community conservation areas in the Western Ghats, Expert Appraisal Committee (EAC) of the Union MoEF (Ministry of Environment and Forests) rejected Adani Energy’s application for 1500 MW Warasgaon-Warangi Pump Storage Project. The committee has asked the proponent to apply afresh for Stage I Clearance, adding several conditions to assessment.

Yamuna Manthan 031024: Threatened River Wetlands

The waterbodies, lakes, wetlands in Yamuna basin continue to face damages and threats from many quarters, including concerned govt departments. In latest examples of this, there are reports of Uttar Pradesh govt’s plan to reduce the eco-sensitive zone (ESZ) of Keetham lake to zero. The wetlands also known as Sur Sarovar is a large ox bow lake formed by Yamuna River in Agra. It is a protected bird sanctuary and has been designated a Ramsar site in August 2020. In Sept. 2022, the Supreme Court had directed the govt to increase lake’s ESZ to 799 ha from 403 ha.

Similarly, the Uttar Pradesh govt departments have also been delaying process to notify Dhanauri wetlands as a Ramsar site in Greater Noida. The case is going on in NGT (National Green Tribunal) for the past many years. In the recent hearing held on Sept. 26, the NGT asked govt department to explain reasons behind delay in notifying the wetlands apart from directing it to remove water hyacinth chocking the wetlands. The next hearing will be held on Jan. 27, 2025.

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 090924: Question marks over Yettinahole should not be buried under money spent

The Yettinahole project has seen protests and question marks right from the time when the project was proposed, none of them have been convincingly answered. As the Karnataka Chief Minister and his deputy commissioned a small part of it, those question marks remain as relevant today, including its hydrological viability, environmental impact assessments and sustainability, with hugely weakening of the western ghats by such major interventions without any credible impact assessments. (see: https://sandrp.in/2013/09/18/yettinahole-diversion-an-imprudent-rs-100-billion-proposition/)

It is good to see CWC and MoEF have also raised some questions and asked report even at this stage. One however expects CWC to raise such questions much earlier in the project cycle and before the project becomes fait accomplice. Else, it seems more like politicking. MoEF could have raised issues of violations before the violations happened on ground and should have refused to provide piece meal forest clearances as it has alleged.

The controversial Ken-Betwa Interlinking project is undergoing several changes being proposed by central and state governments of UP and MP. Firstly, there are plans to build two new barrages at Pailani and Banda and renovate Beriyapur and Pariksha weirs and Barua Sagar dam apart from renovation of 15 dams and large ponds in Mahoba district. Then, the construction of a 21 km link channel will require 271 ha of forest land.

Similarly, the CM of MP has requested to increase irrigation capacity of Patne-Biarma Irrigation Scheme from 90,100 ha to 2,50,000 ha under the interlinking plan. On the other hand, the CM of UP has suggested inclusion of Hamirpur district in the plan.

DRP NB 020924: HYDRA to protect water bodies in Hyderabad – a landmark move?

The Hyderabad Disaster Response and Asset Monitoring and Protection Agency, or Hydra was established under GO 99, dated July 19 2024. A task the agency has taken up in all seriousness is protection of water bodies in the Hyderabad Capital Region (it includes 4 districts). To begin with it has started demolition of buildings illegally built inside the Full Tank Area (FTL) and Buffer area of the water bodies.

In July, Telangana Chief Minister Revanth Reddy replaced the Enforcement, Vigilance and Disaster Management (EVDM) wing of the government with Hydra, a body mandated to tackle illegal encroachment on water bodies in the Greater Hyderabad Municipal Corporation (GHMC) limits and surrounding areas. Its strength was upgraded from around 800 to 2,200 and its officials came directly under the principal secretary, municipal administration and urban development or the CM himself. “Hydra will also ensure the protection of water bodies in and around Hyderabad,” former EVDM commissioner and Hydra chief A V Ranganath said during its inception.

In the past one month there have been some interesting judicial interventions taking up the matters of floodplain, pollution and aquatic eco-system of the Yamuna River in Uttar Pradesh, Delhi, Haryana and Himachal Pradesh. Of these, the most significant one is the NGT order on July 11 fining MoJS & CWC of ₹50 000 each for the non-demarcation of floodplain in Agra.

The fine was to be submitted before Aug. 06,2024 hearing but there is no update available so far on this. It is also not clear whether Yamuna floodplain has been demarcated and officially notified in Agra stretch or not. Earlier in May 2019 and March 2022, the NGT had asked for demarcation of Yamuna floodplain in Agra and Mathura respectively.
