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.

A study of the Nayom-Bayto Rivers Irrigation System (NBRIS) was conducted in 1993. This system is jointly managed by the National Irrigation Administration (NIA) and 14 Irrigators Associations (IAs). The objective of the study is to determine existing performance assessment methodology and performance indicators as used in the NBRIS. The data consisted of secondary sources and also limited primary sources. A rapid appraisal and case study approach were used in the conduct of the study. This study was undertaken as part of the 3 country study (Nepal, Philippines and Sri Lanka) to compare performance assessment methodologies used in these countries. The framework used in the study was based on the work of Bos, et al., 1993. In particular, the management process as applied to irrigation system management is highlighted in this report.
