Marking the National Dolphin Day-Oct. 5, 2026-, this report highlights the deaths, threats and relevant developments concerning the national aquatic animal. In last one year, we have found reports of at least ten Gangetic dolphin deaths, including six in Uttar Pradesh, two in West Bengal, and one each in Bihar and Assam. The reported death toll is higher than in the previous two years, indicating continuing concerns over their survival.

While writing about the landslide dam breach in Taiwan last year leading to 24 deaths, Dave Petley remarked: As always, the focus should be on vulnerability and resilience rather than only early warning systems (EWS). This is indeed worth emphasizing, underlining, highlighting. While early warning systems can be important and must be used wherever possible, it is not a magic bullet. It is one of the many other instruments in disaster management.

The Central Electricity Authority has said in its report that there have been some serious operational and maintenance issues at BBMB’s Pandoh project, part of Beas Sutlej Link Project. In a separate development, Punjab government affidavit in the NGT has said that due to mismanagement at Bhakra-Pong dams, there has been avoidable flood disasters in Punjab in several years. Both developments confirm what we have said about role of BBMB projects in 2023 and 2025 floods in Punjab.

The Himalayan disaster risks are increasing in several different ways, including through new types of disasters that are being added now as is evident from the recent Rasuwa floods in Nepal-Tibet, which originated in collapse of hanging glaciers due to melting of permafrost. The frequency, intensity and spread of the risks are also going up. Considering increasing pace of global warming that is inevitable in coming decades, the disaster risks are only going to go up.

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.

In the third month of the 2026 southwest monsoon season, we have been able to document rivers breaching their respective Highest Flood Levels (HFLs) at least at 10 Central Water Commission (CWC) flood monitoring sites. These sites are spread across five river basins and four states mainly in central and east India.

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.

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.
