Abstract
The purpose of this paper is to analyze the supply mechanism and the impact to agricultural production of Noubishe Perch irrigation project, Nepal. Cooperative relationship between the farmers has made the supply of the irrigation water possible. Because transport cost of the water is high, if farmers do not cooperate, they cannot obtain the irrigation water. In addition, to prevent the free rider, strict rule was decided by Water User Association and the key is equipped in the outlets of main canal. As a result, it became possible to supply irrigation water to the fields and irrigation water changed cropping pattem and improved the crop intensity. And agricultural income increased largely.
