The 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. The project aimed to demonstrate integration of wetland economic values into river basin management at the Kala Oya basin, as a pilot demonstration site. The study also set out to demonstrate the feasibility of managing small irrigation tank systems for biodiversity and ecosystem conservation and achieving livelihood and poverty alleviation goals. 

This paper focuses mainly on the direct and indirect services provided by the small tank ecosystems and possible techniques for valuing those which can be utilised in decision making regarding water and resource allocation.
