Increasing incidences of Glacial Lake Outburst Floods (GLOFs) are being experienced in the Indian Himalayas. One of the most notable examples of GLOF was the Chorabari Lake GLOF that occurred on 16th June 2013 in Kedarnath, Uttarakhand[1] which was triggered by heavy rainfall induced mass movements into the lake. The GLOF devastated villages of Kedarnath, Rambara, and Gaurikund. Around 6,000 people were officially killed, and a significant number of the deaths were linked to the GLOF. Countless bridges and roads were washed away, and about thirty hydropower plants were affected or completely devastated. Several Hydropower projects resulted in exponential losses to life and livelihoods. Whole of Uttarakhand was affected in the disaster, and a significant proportion of it was related with GLOF.

DRP NB 070425: New Impact of Big dams: Increased oxygen intake in inland waters

New research published this week reveals a startling change: the oxygen levels in inland waters has been dramatically reducing since 1900, due to human activities including big dams and pollution. This condition leads to dead fish, collapsing food chains and reducing water quality, among other impacts.
There are simultaneous processes ongoing in inland waters leading to production and consumption of oxygen. The location and processes for both the production and consumption of oxygen has been changing during 1900 to 2010. The Global oxygen consumption in inland waters, net of production has gone up by over 100% from 0.26 Pg/year in 1900 to 0.53 Pg/ year in 2010. While earlier climate change was considered major contributor to this reduction, new research shows it is big dams and pollution that are much bigger contributors. Inland waters now pull nearly 1 billion tons of oxygen from the atmosphere every year — half as much as the entire ocean emits back.

DRP NB 310325: Does Mumbai need Gargai Dam?
Maharashtra Chief Minister Devendra Fadnavis, brushing aside the concerns of forest officials, opposition, environment and available options this week has asked the officials to fast track the Forest and other clearances for the controversial Gargai dam for additional supply of water to Mumbai. This is shocking on several counts.
Our study earlier showed that Mumbai does not need any additional dam including Gargai if it utilizes available local resources including rainfall, reuse of treated sewage, desalinization, demand side management, groundwater recharge, among other cost effective and less destructive options. The Chief Minister of his government has not bothered to respond to these concerns or options. In fact, when our study was published, even government officials in Mumbai had supported our conclusions.

DRP NB 240325: Will the encroachments in Anasagar lake in Ajmer be removed?
Over the last about 4 years, very interesting events are playing out in India’s judiciary regarding the encroachments in Anasagar lake in Ajmer, Rajasthan.
The first order from the National Green Tribunal came to remove the encroachments from Anasagar lake in Dec 2021, reiterated in Aug 2023 as the encroachments were in violation of the environmental regulations and Wetland Rules of 2017. Apparently, the state government with investment of Rs 12 Cr was the biggest encroacher and the investment in the encroached land continued even while NGT order was awaiting implementation.

Rewalsar Lake: Where Faiths, Ecosystems and Communities Meet
Rivers and lakes of the Indus basin have been at the crossroads of civilizations, trade routes, and ecosystems for centuries. They are surrounded by stories and songs from many religions, languages and tribes. One such river is Beas, celebrated as Vipash[1] or the ‘breaker of chains’ in the Rigveda, circa 1500 BC. Beas originates at 4361 meters near Rohtang Pass[2] and flows through the Himalayan state of Himachal Pradesh before meeting River Sutlej in the plains of Punjab, literally “the land of five rivers’. Beas flows for about 470 kms to water some of the most fertile valleys in the world.

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.

SW Monsoon 2024: Rivers Crossing Highest Flood Levels
During southwest monsoon season 2024, SANDRP has tracked at least 64 flood forecast and flood monitoring sites where the respective rivers have crossed the highest flood levels (HFL). Here we present detailed analysis of these sites along with some key observations and other relevant information. SANDRP’s previous reports on the subject can be seen here: HFL breach incidents in 2018, 2019, 2020, May-Sept 2021, Oct.-Nov 2021, May-June 2022, July-October 2022, June-October 2023.

On March 21, 2024, a case related to the Grean Indian Bustard, a critically endangered bird – numbering less than 150 individuals – has led the Supreme Court of India to expand citizens’ constitutional right to life and equality to include the right to be free from the adverse impact of climate change. The PIL filed by M.K. Ranjitsinh asked to protect the GIB from extinction. In 2021, in this PIL, the Supreme Court had passed directions restricting and regulating power lines and renewable energy projects in an area of 99,000 sq km in Rajasthan and Gujarat.
The Supreme Court’s latest order modified directions passed in the earlier judgment. Chief Justice D.Y. Chandrachud – writing for the 3-judge bench including Justices J.B. Pardiwala and Manoj Mishra – has expanded the contours of environmental jurisprudence: from the oft-repeated polluter pay principle–precautionary principle–public trust doctrine to the larger arena of climate justice, environmental inequity and gender justice. However, in the process, the protection the SC gave through earlier order has been withdrawn.

DRP NB 301023: Top scientist Rajeev Raghavan emphasizes need to conserve River Fish
(Feature Image:- Fish catch from a Ramganga stream in Pauri in June 2022. Bhim Singh Rawat/SANDRP)
It is rather rare when we hear the sane voice of a scientist like Rajeev Raghavan neglect of riverine fish conservation in India, from government, research bodies to down to grassroots level. Rajeev Raghavan, incidentally is among the 2% top scientists of the world by the Stanford University, USA. The over emphasis on fish in food, on marine fish, on exotic fish that has such a huge adverse impact on our biodiversity and lack of effort towards conservation of riverine fish are some of the key issues Raghavan emphasizes in this interview. He says most of the fish in the IUCN red list are riverine fish and yet there is so little understanding or effort to conserve such fish or their habitat.
If we see the discussions in the minutes of the meetings of the MoEF’s Expert Appraisal Committee on River Valley Projects in spite of there being permanent presence of a representative of Central Inland Fisheries Research Institute, we see non-existence of any concerns about the impact of the project in riverine fisheries or those who are dependent on them for livelihoods. In fact, we see the shocking spectacle of CIFRI scientists working as consultants to the hydropower companies, working to justify such projects on the highly biodiverse rivers including those of North East India.
