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?

DRP 170826: Assam Floods: Engineering alone cannot help

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.

Over the past one and a half months of the 2026 monsoon season (since June 24), at least eight (& counting) major accidents and disasters have affected hydropower and dam projects across the Himalayan region. In addition, two recurring landslide lakes have emerged as significant hazards that are either linked to HEP construction activities or have the potential to impact downstream hydropower infrastructure. Notably, these incidents span the Teesta, Brahmaputra, Chenab, Ravi, Beas, Sutlej and Yamuna basins underlining that almost no major Himalayan river basin remains untouched by recurring hydro-related disasters.

DRP 270726: Urban Rivers Need Ecological Restoration, Not Concrete, Cosmetic Fixes

Despite sustaining cities with water supply, groundwater recharge, flood moderation, biodiversity, livelihoods and cultural services, India’s urban rivers continue to deteriorate, as highlighted by several reports this week. The Yamuna in Delhi remains the starkest example – ecologically dead across long stretches due to unchecked sewage inflows, shrinking flows and relentless floodplain encroachment. Similar stories are unfolding across the country, with Mumbai’s Mithi, Hyderabad’s Musi, Chennai’s Cooum, Bengaluru’s Vrishabhavathi, Ahmedabad’s Sabarmati, Vadodara’s Vishwamitri, Jaipur’s Dravyawati, Nasik’s Godvarai, Pune’s Mula-Mutha amd several other urban rivers increasingly reduced to sewage drains or heavily degraded waterways.

DRP 20 July 2026: Wither Dam Safety Compliance in India?

It’s been five years since the Parliament passed the Dam Safety Act and the institutions including National and State Dam Safety committees and authorities were set up. However, how safe are our dams and how far have we achieved the Dam Safety Compliance norms? The answer to that question is unlikely to be confidence inspiring. This feeling is reinforced with a number of reports in recent weeks.

Yamuna Manthan July 2026: River without Flows Even During Monsoon

It is well known that excessive diversion of Yamuna waters at the Hathnikund Barrage (HKB) in Yamuna Nagar, Haryana over the past two-and-a-half decades has turned the perennial river into a seasonal stream in its upper reaches during the lean season. However, an analysis of the Central Water Commission’s (CWC) hourly discharge figures and hydrographs since July 1, 2026 reveals that the river is now being deprived of its essential flows even during the monsoon.

DRP 130726: Urge to set up Statutory River Authority

Rivers are the most important eco-systems, providing numerous economic, environmental social and cultural benefits. And in answer to the question, who governs India’s Rivers, we are generally likely to get response blank stares. Same is the likely response about the state of India’s rivers, who monitors our Rivers and so on.

DRP 060726: India needs to improve Rainfall Monitoring?

Two reports from Karnataka this week highlight that over half of the 6605 rain gauges in Karnataka are non-functional. Earlier we saw that IMD does not even report rainfall for at least 11 districts in Arunachal Pradesh alone, possibly since it does not have adequate number of rain gauges in those newly formed districts of Arunachal Pradesh. IMD’s Annual Report for 2025 says P 59): “IMD operates 1,008 Automatic Weather Stations (AWS), 1,382 Automatic Rain Gauge (ARG) stations, 200 Agro-AWS, 5 Automatic Snow Gauge (ASG) stations”. That comes to 2395 locations where rain or snow is measured by IMD, going by the Annual Report. IMD apparently uses rainfall data from other agencies, but their number is not given in the report. IMD also has a large number of manual rain gauges, but the IMD Annual Report does not provide those numbers.
