Abstract
The agricultural sector is the largest consumer of water in the country, which is of particular importance due to the droughts of recent decades, food security, and proper management of water resources. Therefore, it is necessary to provide proper management methods to saving water resources and reduce damage to water resources. For this purpose, for the optimal use of this input, the policy of reducing agricultural irrigation water subsidies in the central part of Baft county was used using a positive mathematical planning model. The research data were collected using random sampling method by completing 150 questionnaires and data of Agricultural Jahad Organization of Baft county for the 2019-2018 crop year and to estimate the data (area under cultivation, water, yield, etc) of the region''s crops from GAMS software was used. The results showed that with increasing the price of irrigation water input, the area under cultivation of barley and wheat crops with a steep slope and alfalfa crop with a gentle slope decrease and the area under cultivation of millet crop increases. Also, the gross income and irrigation water consumption of the region will be reduced under the policies of reducing water subsidies. Farmers'' cropping patterns change in favor of crops that produce more revenue per unit of water consumed. Therefore, prioritizing the policy of reducing irrigation water subsidies is recommended in decision-making and policy programs as an appropriate and practical strategy to increase the region''s water resources.
