Nature Climate Change, Published online: 19 May 2022; doi:10.1038/s41558-022-01360-2

Using a cryosphere–hydrology–crop model, future changes in the amount and sources of water withdrawals for irrigation are investigated for South Asia under different climate change and socioeconomic scenarios. The model reveals that meltwater and groundwater will become increasingly important to complement rainfall runoff to provide food for millions.
