Himalayan Mountain Infrastructure Increasingly Exposed to Climate Risks

Scientific Reports, 27 May 2026

Rising global temperatures increase the exposure of communities and infrastructure to floods and landslides in the Himalayas. This study found that 38% of urban settlements and more than 50% of hydropower facilities in India’s Baspa Basin are located in areas at high exposure to climate-related hazards. The greatest concern is at elevations between 3,000 and 4,500 meters, where atmospheric warming has shortened the duration of seasonal snow cover while simultaneously intensifying extreme rainfall events. With less snow to temporarily store water, more precipitation falls as rain and runs off immediately, increasing the potential for flash floods, erosion, and slope failures. Although this study focuses on a single Himalayan basin, the authors suggest that this assessment framework could help identify climate-risk hotspots in other mountain regions such as the European Alps and the Tibetan Plateau, where warming also is reducing snow cover and increasing extreme rainfall and flood risks.
