Pumping groundwater by Bangladesh’s 16 million smallholder farmers has led to a massive storage capture from surface waters to aquifers rivalling the storage capacity of the world’s large dams, according to a study. Pumping during the dry season reduces groundwater levels that are later restored by leaching from ponds, rivers and lakes during the monsoon months. The capture of surface water leads to the recovery of groundwater levels and helps limit flooding in a process the study authors call “The Bengal Water Machine”.
