Abstract

Assessment of operation and maintenance management efficiency of the small-pumping irrigation systems in both technical and economic aspects is very imperative to provides foundation for planning irrigation efficient improvement in context of pricing mechanism application. Application of the traditional tools and methods has not indicated both quantitative reasons and solutions together. Thus, this study reviewed literatures and practical lessons learn on application of non-parametric program - Data Envelopment Analysis DEA to assess operation and maintenance management of the irrigation systems in Red River Delta. The results found out scientific basis of an optimal math model and applicability of DEA under the input orientated eficiency model according to Constant Returns to Scale CRS and Variable Returns to Scale VRS by using variables of cost and irrigated areas. The indicators of technical efficiency, scale efficiency, allocative efficiency, optimal cost efficiency, general cost units, input cost units and cost structures have been determined. These were a foundation to suggest suitable solution in application of cost structures to distribute the cost resources for operation and maintenance agencies and policies on irrigation water pricing supports by government.
