| Research Abstract |
The purpose of this study was to make clear the economic factors that determine the irrigation efficiency in South Asia.
There is no management organization in Sali Nadi irrigation system in Katmandu basin, Nepal. Farmers whose land is located in tail area of the canal are not guaranteed to use irrigation water in dry season. Gross margin in head and middle is 2.5 times higher than in tail of canal. There is inefficiency of Pareto Optimal. There is no water users organization among the farmers who are benefiting from deep tube-well (DTW) irrigation system in Janakapur area. Due to lack of co-operation the water user has to do every thing by him self to convey the irrigation water to his plots. Therefore the shallow tube-well (STW) irrigation system has been introduced to use water more efficiently.
Water market is well developed in Bangladesh. The water price has decreased by 35%, so that STW might be under break-even point. Due to reduction of water price, the cost share of farmland in favor of landlord is increased.
In Pakistan the problem of water logging and salinity is the result of development of irrigation system without any provision of drainage facility. The investment in drainage projects for controlling this problem has shown the possibility of increase in productivity and cultivability of land. To become more effective, the farmers need more irrigation water and co-operative activities to maintain the irrigation canals.
Green revolution was very successful in Sri Lanka, due to irrigation investment since 1960's. New irrigation development and the rehabilitation projects cost has become too expensive. One of the main reasons is high wage rate.
We concluded that new water user's rule based on Pareto optimal of water resource allocation is necessary for irrigation management system.
