Multiple reports over the past month again highlight serious failures in water governance in major cities in the Yamuna basin including Delhi, Gurugram, Greater Noida, Noida, Vrindavan and Bhopal. The problems range from poor rainwater harvesting and inadequate sewage networks to ineffective sewage treatment capacity, unregulated groundwater extraction and neglect of water bodies.

Interview: Every disaster also presents an opportunity to learn

September 10, 2026 SANDRPLeave a comment

Q: “This incident has indicated that the risks we face in the Himalayan region are increasing with climate change,” said Nepal Prime Minister Balendra Shah. Can we just blame it all on climate change and ignore the role aggressive development poses in an ecologically fragile zone? Or is climate change indeed the main villain?

ANS: Climate Change is a likely trigger for the Rasuwa flood disaster that Nepal and Tibet are facing, starting from the morning of Aug 26, 2026, though the scientists say this needs further studies. But the extent of the disaster depends on a number of factors including callous way in which major interventions have been taken up in the region, including large number of hydropower projects, knowing fully well the inherent vulnerabilities of the Himalayan region accentuated by climate change, by lack of early warning systems, absence of functioning disaster management system including emergency action plans.

In the wake of the Aug. 26 Nepal disaster, civil society groups in India have demanded urgent measures to protect people, mountains and rivers from increasingly complex and cascading disasters across the Himalayan region. The statement issued under the umbrella of People for Himalaya rightly appeals for high-altitude and trans-Himalayan areas to be treated as no-go zones for high-risk mega infrastructure projects, including large hydropower projects.

There have been at least three incidents of leakages from fly ash dykes at Reliance’s Sasan UMPP in MP & NTPC’s Unchahar Plant in Raebareli, UP in Aug. 2026. All the three incidents have considerably affected nearby village and farmer communities in both the states. Notably, both projects have also experienced ash dyke related leakages and failures in the recent past, raising serious concerns over safety of the structures and safe disposal of the toxic fly ash.

Himalayan Floods Are Not Just a Water Event, They Are a Debris Event

September 3, 2026September 4, 2026 SANDRPLeave a comment

As I write this, over 1,200 people are dead across Nepal and China, and nearly 5500 more are missing. About 900 people are trapped in hydropower tunnels clogged by debris. Herculean national and international efforts are being made to bring them out, but the tunnel entrances are sealed by dense plugs of compressed sediment, and rescuers have no idea of the extent of that blockage. An Australian tunnel expert summed up, “we might only have to dig 10 meters, or we might have to dig 100 meters.” [1]

DRP 310826: Nepal’s Rasuwa flood disaster: Is there a limit to Human Folly?

Even as Nepal, Tibet, India and other countries whose citizens are in missing list following the Aug 26 2026 Rasuwa flood disaster for Nepal, and even as the full dimensions of the disaster are still unfolding, a Bloomberg journalist asked SANDRP a pertinent question. Seeing the major role played by operating and under construction hydropower projects in the disaster and the missing list of hundreds of people from such projects, he noted that deaths at disaster hit hydropower projects in Himalayas is a recurring story. During and after every such disaster, there is talk of learning lessons such projects, but there is little change in decision making process. His question was, is there a limit to human folly, beyond which we will see some genuine change?

Among many analyses of the recent Assam Floods, three contrasting ones stand out to illustrate the limitation of supremely confident perspective that engineering alone will solve the problem. One of them is by Mitul Baruah and another one is on edit page of The Times of India on Aug 17 2026. The third one by Arupjyoti Saikia is published in Indian Express. The one in TOI does not look at cultural or historical aspects of floods in Assam, nor the uniqueness of unprecedented upper Assam floods & the reasons behind it. The analysis by Mitul Baruah, in contrast, takes into account all this and in fact comes from lived experience in Majuli. Arupjyoti Saikia, an environmental historian, takes historical perspective.

Yamuna Manthan Aug 2026: Floodplains remain under threat

Three recent studies have once again highlighted both the severe degradation of the Yamuna and the critical role of its floodplain in Delhi. Their findings make it clear that cleaning sewage alone will not revive the river. Protecting natural flows, restoring floodplain connectivity and conserving wetlands are equally important for reducing flood risk, recharging groundwater and sustaining the river’s ecology. Undoubtedly, the Yamuna floodplain has already suffered extensive encroachment, fragmentation and ecological damage due to weak governance.

The two important developments over the past week have once again highlighted the worrying state of dam safety affairs in India. Firstly, the information shared by Union Jal Shakti Minister on Aug. 03, 2026 in Parliament has revealed that the National Dam Safety Authority (NDSA) has updated Emergency Action Plans (EAPs) for only 735 of the country’s 6,598 completed and operational specified dams as of July 30, 2026.
