Climate change
South Asian countries are expected to experience more flooding in the future as the monsoon pattern intensifies. Across Asia as a whole, 100-year extremes in vapour transport (directly related to extreme precipitation) would become 2.6 times more frequent under 1.5 °C (2.7 °F) of global warming, yet 3.9 and 7.5 times more frequent under 2 °C (3.6 °F) and 3 °C (5.4 °F). In parts of South Asia, they could become up to 15 times more frequent. At the same time, up to two-thirds of glacier ice in the Hindu Kush region may melt by 2100 under high warming, and these glaciers feed the water basin of over 220 million people. As glacier meltwater flow diminishes after 2050, Hydropower generation would become less predictable and reliable, while agriculture would become more reliant on the intensified monsoon than ever before. Around 2050, people living in the Ganges and Indus river basins (where up to 60% of non-monsoon irrigation comes from the glaciers) may be faced with severe water scarcity due to both climate and socioeconomic reasons.
