Economic Pricing of Water in Pistachio Production of Sirjan

Given the strategic remarkable rank of pistachio in non-oilexports, inputs’ management in its production is so important.as the scarcest input in agricultural sector, water is considered tobe among the most important inputs of pistachio production.water inadequate supply and climate conditions increase waterdemand in pistachio growing areas. it is necessary to determinethe real value or price of water for establishing a balance betweenits demand and supply. therefore, this study has aimed atestimation of water economic value. the method used in this researchis the production function approach. requested data setswere obtained from the questionnaires was filled out for cropyears of 2013-2014. the results show that the average economicvalue of irrigation water is 50360 rls but the average price paidby farmers is 1771 rls per cubic meter of water. thus, there is awide gap between water value and the price paid by farmers withwhich appropriate pricing of water based on its economic valuecan be eliminated.
