The Hindu Kush Himalaya (HKH) region extends 3,500 km over all or part of eight countries, from Afghanistan in the west to Myanmar in the east. It is the source of ten large Asian river systems, including the Indus. The HKH provides water and other ecosystem services and is the basis for the livelihoods of 236.9 million people in the region. Improved water resource management in mountain areas is essential for the sustainable development of the region and downstream countries.
