Himalayan Glacier Melt Threatens Water Security and Livelihoods

Scientists say glaciers in the Himalayas are shrinking faster than before.

Glaciers are large rivers of ice that store water.

As they melt, rivers may first get more water and later receive less.

This change could threaten drinking water, farming, and other needs.

The region may reach “peak water” around the middle of this century.

Melting ice can also create unstable lakes held back by loose rock and ice.

A glacier collapse in late August caused landslides and floods near Nepal and Tibet.

The report says at least 1,300 people died and more than 5,300 were missing.

Millions of people live below these dangerous lakes and depend on Himalayan water.

Key facts

Study organizations: Systemiq, the Integrated Mountain Initiative, the International Centre for Integrated Mountain Development, and India’s G.B. Pant National Institute of Himalayan Environment.
Glaciers monitored: Only 21 glaciers are currently monitored on the ground out of an estimated 40,000 in the Hindu Kush-Himalaya region.
High-risk lakes in India: Nearly 200 glacial lakes have been identified as high risk, including 56 classified as very high risk.
Reported casualties: At least 1,300 people were confirmed dead and more than 5,300 were missing across Nepal and China’s Tibet region.
Peak water: The study says the region is approaching the point when river flows stop rising and begin declining, potentially by mid-century.
India’s economy: The Himalayan region underpins more than 20% of India’s GDP, according to the report.
Natural disasters: The Himalayan region represents about 18% of India’s land but roughly 35% of its natural disasters.
