Many of the largest rivers in the Himalayas Hindu Kush region are strongly dependent upon snow and glacial melt for waterflow
Ieva Rucevska, UNEP/GRID-Arendal
Except for the fact that glaciers are melting rapidly in many places, we do not have adequate data to more accurately project when and where water scarcity will affect irrigation schemes in full. Making accurate projections is also difficult because of variations in the effects on ground and surface water, as well as on water for urban needs and industrial purposes Furthermore, the cost of water may also increase, seriously complicating the water scarcity question. Recent studies show that cost of water has increased by about 400–500% since 1990 in the Indo-Gangetic Basin of India.
