In this regard the International Water Management Institute (IWMI) suggests that a mix of storage options, including aquifer recharge, restoring natural wetlands, enhancing soil moisture and small ponds and tanks would complement reservoir storage to increase water availability.
Peter McCornick, deputy director-general of the International Water Management Institute in Sri Lanka, who was not involved in the research, says: “The message I would take from this [paper] is that with improved water management, it’s theoretically possible to increase food production without expanding the area of land being farmed.”
