The Hindu Kush-Himalayan (HKH) region, stretching from Afghanistan to Myanmar, holds the source of 10 large Asian river systems including the Ganges, Indus and Yangtse.

These rivers together provide water for consumption, irrigation and industry to over 1.2 billion people.

CEH facilitated the creation of a UNESCO initiative to encourage sharing of data and scientific methods between 12 countries in the region: contributing models, analysis and development of methods for estimating runoff and flows.

This knowledge sharing allowed HKH-FRIEND to address critical issues such as the effects of global change on Himalayan glaciers and snow cover, and how to predict and mitigate the impact of glacier lake outburst floods. (Managing environmental change)
