Abstract

Optimal management and proper use of available water resources is an inevitable necessity. Therefore, this study was conducted to investigate the effect of irrigation water prices on its demand in the agricultural sub-sector of the country. For this purpose, to determine the price of water shade and its demand function in a different way from other studies and using the obtained coefficients in calculating the non-parametric random inclusive model, the data were determined and the price of irrigation water shade using coefficients obtained. It came from this model. The required data for the research were also collected from the website of the Ministry of Jihad Agriculture during the annual period of 2005-2016. The results showed that the average efficiency of irrigation water in the agricultural sub-sector during the study period was equal to 83.02%. Also, the results of estimating the irrigation water demand function showed that the irrigation water demand in the agricultural sub-sector is inelastic and 0.16 and the elasticity of water demand to technical efficiency is equal to 8.37. Based on the obtained demand function, the variables of water price, price of other production inputs and water efficiency have a significant effect on irrigation water demand in Iran's agricultural sector. Among the studied variables, technical efficiency, with the largest coefficient, is considered as the most effective factor in irrigation water demand. This result shows the need to pay more attention to the issue of water efficiency and efforts to improve and improve the efficiency of irrigation water in the agricultural sector. Also, according to the results, increasing the price of irrigation water in agriculture sub-sector will not have much effect on reducing demand and water consumption in this sub-sector and reducing irrigation water consumption in agriculture sub-sector will be possible by improving water technical efficiency.
