Determining the Economic Value and Allocation of Pishin Dam agricultural Water, Sistan and Baluchistan Province

The present study was carried out to estimate economic value of agricultural water in farmlands of Sarbaz, Sistan Baluchistan, which are under irrigation network of Pishin dam, so that provides sustainable use of water resources and enhances water use efficiency via determining agricultural water price and optimal farming pattern. Technical coefficients belong to crop year of 2010-13, obtained by randomized stratified sampling among 340 regional users. Results showed that the water is not used efficiently and the same volume of available water can be used for farming in larger extent; moreover water price received from the farmers is much lower than water economic price. Regarding excess available water, it is recommended that water allocation management be performed in such a way that cultivated area is extended and water pricing is equal to economic value. Moreover, due to lack of planting pattern, responsible bodies should set appropriate economic faming patterns for improvement of regional agriculture according to climatic condition, agricultural policies, water capacity and relative advantage of crops.
