The ancient tank system supported people’s livelihoods in times of foreign invasions. These livelihoods were environment friendly, and had the capacity to feed many a generation who constructed them. Today, many rural people still use these tanks for irrigation and other purposes. IUCN Sri Lanka Country Office implemented a project on integrating wetland ecosystem values into river basin management in collaboration with the Mahaweli Authority of Sri Lanka.
