The interim results of the study as conducted by the International Irrigation Management Institute (IIMI) is presented. Existing practices of farmers and the National Irrigation Administration (NIA) personnel in managing the available water supply are highlighted. These practices were analyzed for possible adoption in other NIA systems. The paper also presents opportunities for improvements to optimize land and water use during the dry season. Limited water supply and suitable soils were the main physical factors that enabled farmers to effectively irrigate rice and non-rice crops during the dry season. The active involvement of the irrigators' association (IAs) in water allocation and distribution resulted in optimal or effective use of limited water supply. Further investigations into other factors, like the rice priority policy and other socio-economic incentives that will make irrigated crop diversification attractive and profitable to farmers were suggested.
