Does solar irrigation threaten groundwater sustainability? Evidence from India and Bangladesh by Alam, Mohammad Faiz, Varshney, Deepak, Mitra, Archisman, Pavelic, Paul, Mahapatra, Smaranika, Habib, A., Krishnan, S., Sikka, Alok, Ravindranath, Darshini

“…In India, grid-connected SIPs with feed-in incentives reduced water use in alluvial aquifers, while hard-rock systems showed little change. The findings highlight that groundwater impacts are context-specific, with well-designed solar models offering low-carbon irrigation without major sustainability risks.…”
