Integrated management of water demand by economic approach in Northern Sistan and Baluchestan province

This study survived the factors affecting on water demand in agricultural and domestic consumption, amount of water demand and income and price elasticities in household sector in the north of Sistan and Baluchestan. For this purpose, we used the Stone-Greay utility function in the household sector and considered quantitative and qualitative factors influencing the optimal water resources management in agriculture using the Logit model. The results of water demand function estimation in household sector showed that the demand for per capita in general condition was equivalent to 61.5 cubic meters per year and the extera consumption per capita in this case was 26.8 cubic meters. Also, income and price elasticities of household water demand in this case were equal to 282.0 and 373.0 respectively, indicating that the demand for water was less tangible than price; Income stretch is less than one, indicating the necessity of water. The results of estimation of the optimum water consumption model showed that the most effect was on the work experience and history variables and then the variables of using fertilizers and chemical pesticides, type of communication channels, irrigation methods, education and education level had the most effect on optimal use of agricultural water resources.
