Discusses the differences in the irrigation production function and related management functions between paddy and other crops. Advances the theory that, because of the physical parameters of the way water is stored on and drained off paddy fields and the ultra-sensitivity of paddy yields to water stress, paddy irrigation systems have a self-regulating property that leads to a reasonably optimal allocation of water supply between farmers. Thus, in complete contrast to other crops, it is doubtful if management improvements in the form of rationing and rotation of water supply to farmers would result in cost effective improvements over the allocation achieved by naturally functioning systems. Restricts the discussion to the small (less than 1,000 ha.) rivertine paddy irrigation systems characteristic of Southeast Asia and to the high yielding varieties of paddy.

Using a production function, marginal productivity of farm inputs and benefit-cost analysis, we explore the economics of selected water control technologies. From the production function, all farm inputs, including irrigation water is found to have a significant and positive effect on yield. Marginal value products of farm inputs are found to be positive but their magnitudes differ by type of control structures, crop type, agro-ecology and regions. The net present values of all water control structures are positive. There is a favorable precondition for sustainable adoption of these controls technologies and institutionalizing some sort of cost recovery schemes. The level of education, the ratio of irrigated land allocated to irrigated annuals and perennials, access to markets and off-farm income are found to have significant effect on successful use of these control structures. Recommendations and policy implications are drawn accordingly.
