Estimation of Sustainable Utilization Model of Common Groundwater Aquifers: A Case Study of Urban and Operators-Game Theory

The growth and expansion of the population on the one hand and the supply of water to provide food to the growing population on the other hand in recent decades has caused serious differences among the users of water resources. Due to the limited resources, the need for sustainable use of these resources is evident. In systems consisting of several independent decision makers, game theory is a powerful tool for users to achieve a stable equilibrium point. The purpose of this study is to present a dynamic model in order to resolve the differences between the operators of the common greenhouse and achieve a stable balance. In this article, based on the way of cooperation and degree of interaction of water users, their behavior is modeled in the form of three scenarios as model of static games without cooperation, model of dynamic games without cooperation and finally, model with full cooperation. In order to compare the results obtained from application of the above scenarios, the exploitation of a common groundwater aquifer has been studied between urban and agricultural exploiters. The results show that the revenues from the model with full cooperation are more than the models without cooperation.
