2025 Western Himalayan Floods: What can be done to reduce disastrous impacts?
Scary visuals and messages on social media as also some of the pronouncements of the Supreme Court about Himachal Pradesh have shown that Western. Himalayan states have faced multiple flood disasters in the ongoing SW Monsoon 2025. Landscape of Himalayas is known to be vulnerable to landslides, mudslips, cloudbursts, flash-floods, GLOFs, erosion, seismicity and floods. While some floods are inevitable in the kind of climate prevailing here, how they become disasters is linked to the way we have treated the landscape, environment, regulations, people and floods.

This 2024 annual overview focusses on important reports highlighting the safety and sustainability issues of the hydro and dam projects in India in 2024 in the context of Climate Change, including Glacier melt and GLOFs. The compilation shows that the climate change driven extreme weather events have become significant threat for the structural safety of these projects.
This is even more relevant in inherently vulnerable areas like the Himalayas and Western Ghats from the point of view of seismic activity, young erosion prone mountain, flash floods, avalanches and landslides. Here the impact of climate change effects like more intensified hydrological cycles, cloud bursts, reduction in snow fall, glacier melts and GLOF (Glacier Lake Outburst Flood) increase the vulnerability including landslide dams and avalanche dams.
