While proposed irrigation projects are subjected to extensive study, ex post analyses are rarely conducted, particularly in developing countries. Ex post analyses can provide valuable information for future irrigation investment decisions. Quite simply, they can help identify what worked, what did not, and why. This project examines irrigation development over the past 50 years in the Uda Walawe River Basin, Sri Lanka. The outcomes of this research reinforce the importance of integrated planning, realistic expectations of farmers, and contingency planning for unanticipated events.
