DRP 280926: Early Warning System important, but not a magic bullet

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 Sept. 2026 tunnel leakage at NHPC’s Parbati-II HEP in Kullu’s Sainj Valley triggered a sudden flow of water, muck and debris towards Palchara village. Although there was no loss of life, the incident has damaged houses, agricultural land and local infrastructure. It occurred amid a series of leakage and seepage incidents reported in and around the project in recent years, raising renewed concerns over tunnel safety, muck dumping and slope stability in the project area.

DRP 210926: Mismanagement at BBMB projects confirmed by CEA and Punjab
(Feature Image: The Tribune’s file photo of Pandoh dam)
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.

DRP 140926: How prepared are we to face Himalayan Disaster Risks?

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.

Interview: Every disaster also presents an opportunity to learn
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 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.
