Irrigation has played a contributing role in enhancing agricultural production and productivity in Nepal. Farmer-Managed Irrigation Systems (FMIS) have been operating for more than 25years using local capacities. A survey was accomplished during April-May, 2005 to evaluate the changes that have been brought about by the introduction of FMIS at Kumroj in Chitwan district. The changes in crop species, cropping area, irrigated area, crop production, productivity and cropping intensity after the introduction of FMIS were explored. Comparisons were made in between farmers participating and not participating in FMIS. There was a total increase of about 47% in irrigated land since the introduction of FMIS. This has helped increase crop production as crops can be grown more than once a year and as a result cropping intensity has been tremendously improved to more than 256 percent. Further, the cropping areas as well as the crop productivity have been greatly influence with the inception of FMIS. The change in the cropping pattern from cash crop oriented to food crop production to combat food insufficiency in Nepal. Considering the successes of FMIS, development of small-scale farmers managed irrigation system to improve agricultural production in Nepal should be emphasized.
