The Himalayan Snow Crisis: A Systemic Collapse Threatening Water Security
The Ganga basin, amidst a regional snow persistence decline in the Hindu Kush Himalaya, shows above-normal snow levels in 2026. The ICIMOD report highlights shrinking snow reserves threatening water security for billions dependent on major river basins. Urgent action is needed in science-based governance and integrated water management.

The Ganga basin stands out as one of the few exceptions in the HKH region, exhibiting above-normal snow persistence in 2026. This occurs even as overall snow cover in the Hindu Kush Himalaya hits a record low deficit for the fourth consecutive year.
The International Centre for Integrated Mountain Development (ICIMOD) highlights this troubling trend in its annual report. Over the past couple of decades, the region has experienced 14 winters marked by below-normal snow persistence. This systemic decline poses a looming threat to water security for the vast populations relying on the area's river basins.
While the Ganga basin showed a 16.3 per cent increase in snow persistence, major basins like the Mekong and Tibetan Plateau recorded significant deficits. Experts call for urgent regional cooperation and science-based governance to address interconnected water supply and management challenges.
