Storing water to alleviate floods and droughts

Published on by

A new study by IWMI explores a win-win approach that could boost agricultural production and contribute to flood control on the Chao Phraya River. The study proposes a strategically targeted program of managed aquifer recharge (MAR). MAR is typically used to store wet-season flows in dry climates but has not been systematically employed to capture floodwaters to protect urban infrastructure in the tropics. The economic study shows that the investment cost to implement the project could be recovered in 14 years. The project would generate around US$250 million annually in export earnings while helping to alleviate poverty.
