Impact of climate change on water resources and crop production in Western Nepal: Implications and adaptation strategies por Risal, Avay, Urfels, Anton, Srinivasan, Raghavan, Bayissa, Yared, Shrestha, Nirman, Paudel, Gokul Prasad, Krupnik, Timothy J.

“…Farmers making use of surface water for irrigation in upstream subbasins may inadvertently cause a decrease in average water availability in downstream subbasins at approximately 14%, which may result in increased need to abstract groundwater to compensate for deficits. Well-designed irrigated crop rotations that fully utilize both surface and groundwater conversely may increase groundwater levels by an average of 45 mm from 2022 to 2050, suggesting that in particular subbasins the cultivation of two crops a year may not cause long-term groundwater depletion. …”
