Abstract: Significant problems of water shortage and deteriorating water quality are contributing to a growing water crisis in many countries such as western Asia. This situation requires creative solutions to achieve sustainable resources management. In the Western Asia irrigation (agricultural sector) extraction have bad major impact on the water resources environment. Finding ways to meet agricultural demands and also achieve positive environmental and economic outcomes requires the aid of modeling tools to analyze the impact of alternative policy scenarios. These scenarios seek to asses the impact of option for allocation of limited water resources between agricultural production and the environment. This study presents a novel approach for optimizing these objectives by combining system dynamics and constrained linear objective optimization approaches. The network simulation optimization model NSOM has been coupled with a linear programming mathematical algorithm model. This paper concludes that system dynamic optimization approaches is a useful tool for agricultural water use. NSOM has the capability to compare the simulation and optimization dynamic results synchronized in time for each variable involved in the model. The comparison shows that VENSM optimizer does achieve the same results. Rationalization water consumptive require a lot of researches to achieve objectives by using scientific means.
