Economic value of irrigation water using the flexible production functions (Saveh case study)

Using the flexible production functions, the economic value of irrigation water in Saveh region was estimated. The results of the study show that the average economic (shadow) price of one cubic meter of irrigation water at the farm gate used in wheat production is 215 Rials, in cotton production is 386 Rials, in Cucumbers production is 342 Rials, and in pomegranate production is 265 Rials. A comparison of estimated and the current price of water shows that the economic value of irrigation water is much higher than what is currently received by the local water authorities. Under these circumstances, an inappropriate use of water and the lack of incentives in investing in water saving technology are expected.
