Himalayan glaciers are losing mass 65% faster than a decade ago, according to a new report by Systemiq and partners. Only about 21 of an estimated 40,000 glaciers are monitored in detail, leaving a widening gap as glacial lakes grow more unstable. The report estimates Himalayan water underpins roughly 20% of India's GDP, while mountain states capture only about 5% of that value.

Key Facts

Himalayan glaciers are losing mass 65% faster than they were a decade ago, according to a report by Systemiq, the Integrated Mountain Initiative, ICIMOD, and GB Pant National Institute of Himalayan Environment.
Only about 21 of the estimated 40,000 glaciers across the Himalaya-Karakoram region are being monitored in detail and on a sustained basis.
India's government told parliament in July that 56 glacial lakes had been classified as "very high risk" following a 2025 scientific assessment of 189 high-risk lakes in the Indian Himalayan region.
The Central Water Commission is monitoring 2,485 glacial lakes larger than 10 hectares across India's Himalayan river basins.
The report estimates that Himalayan water underpins roughly 20% of India's GDP, sustaining wheat, rice, tea, hydropower and pilgrimage economies, while mountain states capture only about 5% of that value.

Accelerating Glacier Loss

Himalayan glaciers are now losing mass 65% faster than they were a decade ago, according to the report by Systemiq, produced with the Integrated Mountain Initiative and with technical contributions from ICIMOD and GB Pant National Institute of Himalayan Environment. The findings come after floods in Nepal and Tibet killed more than 1,300 people and caused widespread destruction. As glaciers retreat, they can leave behind expanding lakes held back by unstable deposits of rock and ice, while warming destabilises permafrost and high mountain slopes, increasing the possibility of cascading hazards.

Monitoring Gap

Only about 21 of the estimated 40,000 glaciers across the Himalaya-Karakoram region are being monitored in detail and on a sustained basis, according to the report. India's government told parliament in July that 56 glacial lakes had been classified as "very high risk" following a 2025 scientific assessment of 189 high-risk lakes in the Indian Himalayan region. The Central Water Commission is monitoring 2,485 glacial lakes larger than 10 hectares across India's Himalayan river basins. Some 18% of Indian land is Himalayan, yet the region accounts for about 35% of disasters, according to the report.

Economic Dependence

The report estimates that Himalayan water underpins roughly 20% of India's GDP, sustaining wheat, rice, tea, hydropower and pilgrimage economies. Mountain states capture only about 5% of that value, according to the report. ICIMOD says "peak water" is expected around mid-century in most Hindu Kush Himalayan river basins, the point at which glacier runoff reaches its maximum before declining as glaciers lose mass. Economist Lord Nicholas Stern, chair of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics, said, "The Himalayas are the Third Pole."
