        Considering Iran geographical location, water is the most limited factor in agriculture section. Therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. The purpose of this study is assigning cultivation pattern based on economic value of water in Gotvand Township in agronomic year 2008-2009. So it was necessary to computes the water production value in producing important crops such as wheat, barley, corn, potato and water melon. To get objectives production function method was applied. Also different form of production forms such as Translog, Leonteaf and Quadratic estimated. The results show that the economic value of each m3 water in the products ranges between Rls.228 to Rls.411. based on the results, corn, wheat, tomato, malt and water melon have respectively priority in regional cultivation.

        Water pricing is considered as one of the most important management tools of water resources, which can result in optimized allocation in the agricultural sector. In this regard, this study estimated the cost of water and the value of water in the farmlands covered by the selected manmade ponds (MMPs) within the Alborz project area in Mazandaran Province using the engineering economics methods and production function calculation. The required data were collected via a survey conducted in 2013-2014 growing season. Sample size was estimated to be 198 people. After studying various production functions, transcendental production function was chosen as the best functional form. Next, the economic value of water for rice in the basin covered by the selected MMPs was calculated to be 19,065 IRR per m3 using an estimation of the production function. In addition, the cost of water per m3 in the selected MMPs was obtained as to be 868 IRR at the interest rate of 22% and 394 IRR at the interest rate of 12%. Comparing the cost of water with the economic value of water demonstrated that the economic value of water is higher than the cost of water in the selected MMPs, and that both of them had great difference with the price paid by farmers. The implication is that the existing gap between the real price and the price paid by farmers should be filled by the economical pricing of water. تفاصيل المقالة

        Economic valuation of water is useful in the administration and management of water. Population growth and urbanization caused municipal water demand increase in Iran. Limited water resource supply and urban water network capacity raised complexity in water resources management. Present condition suggests using economic value of water as a criterion for allocating policies and feasibility study of urban water supply projects. This study use contingent valuation method for determining economic value of drinking water in Kohkiloye & Boyerahmad province. Required data set were obtained from 177 questionnaires by applying stratified random sampling in 2011 year. From 136 investigated urban households 111 ones are willing to pay more for qualified drinking water. Also, from 41 investigated rural households only 3 ones are willing to pay more for qualified drinking water. Results indicated that economic value of drinking water is 6877 Rial per cubic meter. تفاصيل المقالة

        Given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. As the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.Water inadequate supply and limate conditions increase water demand in pistachio growing areas. It is necessary to determine the real value or price of water for establishing a balance between its demand and supply. Therefore, this study has aimed at estimation of water economic value. The method used in this research is the production function approach. Requested data sets were obtained from the questionnaires was filled out for crop years of 2013-2014. The results show that the average economic value of irrigation water is 50360 RLS but the average price paid by farmers is 1771 RLS per cubic meter of water. Thus, there is a wide gap between water value and the price paid by farmers with which appropriate pricing of water based on its economic value can be eliminated. تفاصيل المقالة
