Impacts Water

India’s main water sources consist of precipitation on the Indian territory and flows, many trans-boundary, originating in neighboring mountain regions. Many of the flows originating in the Himalayas are fed by glacier melt water. Glaciers serve to smooth flows, providing a reliable water source during the dry season. As such, the potential loss of glaciers as a result of climate changes and warming may be a significant threat to water resources in India. Precipitation over a large part of India is concentrated in the monsoon season during June to September/October. The unreliability of precipitation, dynamics of social vulnerability, and proliferation of chronically water scarce regions mean that an estimated 180 million people are already living in chronic (year-round) and severe water scarcity. The irrigation sector accounts for 83% of India’s national fresh water consumption. Changes in key climate variables, namely, temperature, precipitation, and humidity, may have significant long-term implications for the quality and quantity of water for agricultural use.
