This paper reports on a detailed sociological study carried out as the NGO (or change agent) was completing three-year projects in two sites, Nagadeepa and Pimburettewa. The study describes the change agent's strategy, and analyzes its impact and the perceptions of farmers and government officials regarding its impact. The case study is placed in a wider context, in terms of both the participatory management policy of the Government of Sri Lanka, and the lessons learned that are relevant for NGOs working in other countries as well.

Increasing the area under irrigation and the widespread adoption of seed-fertilizer technology were the major factors that contributed to enhanced rice production in Sri Lanka, enabling the country to achieve self-sufficiency in rice. In recent years, there has been a shift in emphasis from expanding the irrigated land base to enhancing the productivity of irrigated land through diversification of agriculture and improvement of rice production, with better water management in irrigation schemes. This report attempts to assess how the irrigation sector in Sri Lanka is adapting itself to these new challenges. It analyzes the future direction of irrigation in Sri Lanka in light of recent trends in public and private investment in this sphere, and the revolution in groundwater development brought about by the poor performance and gradual deterioration of existing irrigation schemes.

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.
