Abstract

The lack of proper management and adequate water supply in agricultural sector has been followed by many harmful social- economic and environmental side effects. The main objective of the present study is to estimate the value of supplying adequate water and to compare it with the lost agricultural income due to the lack of adequate supply of agricultural water from the Latyan and Mamlu dams in the city of Varamin. To achieve the objectives of the field research study in 1395, Using the Michael and Carson method, the number of samples was selected and, by completing 320 questionnaires, information was obtained from farmers in Varamin plain. In order to estimate value of water supply, the conditional valuation and single bounded dichotomous choice technique were utilized. The results show that the water supply value is 1575 rials per cubic meter, compared with the values obtained in water (300 rials per cubic meter) higher. According to the construction of two dams and Mamlou Latyan that the allocation of 160 million cubic meters of water to the plains of Varamin is, Water was estimated total value of 252.000 million riyals. Also, based on the price of products in 1395, the lost income of farmers was estimated at 3.251.850 million rials due to insufficient supply of water; By comparing the total value of water lost income of farmers was found that the supply of water from the perspective of farmers due to loss of income of farmers and the harmful effects of social-ecological entered the plains of Varamin due to lack of adequate supply of water. The results of this study can be used to planners and policy makers in the water sector it may act as a criterion in estimation of the benefits of new water transfer projects and water supply for reliable and adequate irrigation.
