Abstract
This paper addresses the importance of an institutional mechanism to allocate and distribute irrigation water properly, to reduce conflicts and to mobilize financial support for sustainable rice production. The study reveals that the contributing factors affecting the performance of farmer-managed irrigation systems for rice production are plot size and the application of seed, fertilizer and pesticides, and the influencing factors are water adequacy during the dry season and a fixed schedule of intermittent flow of water distribution. Water inadequacy and dissatisfaction on the timeliness of water distribution are the potential sources of conflicts, whereas the ability of farmers to pay irrigation fees and the acceptance of a fee system are the major concerns about the financial support for irrigation operation and maintenance. The accountability of a water user's association is the main factor influencing the success of an institutional role in the sustainability of rice production.
