In this study, the effect of agricultural water productivity for optimization of the cultivation pattern in the irrigation network of Doosti Dam has been investigated. For this purpose, the amount of costs and revenues from the sale of agricultural products and the water demand of these products were used as the main parameters. In this regard, the study area (Doosti Dam Irrigation Network) was divided into six areas in terms of catchments, social context, scope of activities of aquifers and productivity index according to field surveys for all Areas were identified. The results show that with the implementation of the proposed plan, income in the whole area will increase by 20% and the irrigation system of the region will be optimized. Also, the annual water demand and unmet water demand of each area of the study area were calculated according to the available water resources and also based on the use of WEAP model functions. As a result, irrigation efficiency increased and water demand of agricultural products decreased until the project horizon (2030). The results of this study in the study area, can provide a good management approach to make future decisions for policy makers and stakeholders in the field of water in this area.
