Many irrigation systems in the dry zone of Sri Lanka have water shortage problems. In spite of the fact that water shortage is a problem, water consumption is very high during land preparation which takes prolonged periods of time. This paper analyzes the impact of institutional interventions on efficient water management, especially during the land preparation period, based on research conducted in Huruluwewa, Rajangana, Nuwarawewa and Minneriya irrigation schemes in maha season (wet season which is from October to mid January) 2001/2002. It provides a comprehensive understanding of the factors behind prolonged periods of land preparation so that system managers and farmer communities can develop appropriate interventions to reduce water consumption during this period.

This paper is a synthesis of IIMI's research on irrigation management for crop diversification in Indonesia, the Philippines and Sri Lanka. It provides some conclusions and recommendations, the potentials and constraints to more intensive non-rice production during the drier part of the year in irrigation systems that have been developed primarily for rice production. The research results obtained from selected irrigation systems sites in the three countries from 1985 to date were analyzed and compared by establishing common reference points where they existed, such as common constraints, potentials and institutional arrangements and by explaining differences based on observed data for each system. Relevant secondary data other than from the research sites were located to shed further insight in the synthesis.

This report documents part of an operational experiment in Kalankuttiya Block of Mahaweli System H during the 1987 yala (dry season). The experiment or "action research" was conducted by the International Irrigation Management Insti tute (IIMI) in cooperation with the Mahaweli Economic Agency of the Mahaweli Authority of Sri Lanka. The experiment was the outgrowth of studies which focused on constraints to non-rice crops during the dry season. Careful monitoring of irrigation and cropping patterns in selected areas of the system, conducted from yala 1985, had documented three important constraints to di versified crops: 1) inadequate water control at the secondary and tertiary levels of the system, 2) lack of organization for water sharing from the secondary level downward, and 3) poor conununication between farmers and agency staff regarding water delivery schedules

Sri Lanka is a country with vast spatial and seasonal variations of water supply and demand. Statistics in the form of aggregated information at national level sometimes mask issues of local water scarcity. But when the same indicators are used at subunit level, a substantial area of the country comes under severe water-scarce conditions. Knowledge of subunit level water scarcities is very important because most of the food requirement of the country at present comes from water-scarce regions and projected additional requirements are also to be met by the same regions.
