Based on the statistics, the agriculture sector is responsible for consuming more than 90 percent of water in Iran. To date, the growing demand for water in the agriculture sector has largely been met by mining fossil groundwater resources. Indeed, about 90 percent of groundwater use belongs to the agriculture sector. This unsustainable trend cannot continue for a long time since groundwater resources are limited. So, decision-makers need doing some urgent, effective actions to handle this problem. The main objective of this study is understanding the underlying cause of the problem and evaluating suggested policies to address the crisis. The model is based on “tragedy of the commons” theory and tries to explain how farms attempts to maximize their profits turns to a serious threat for sustainability of groundwater resources. In the following, the model has been used to evaluate various strategies for avoiding the depletion of groundwater resources. For this purpose, “gap analysis” has been used. In gap analysis, the future under the present strategy is forecasted. Then, objectives or desired future is identified and the gap between the objectives and the future conditions under the current strategy is determined. Finally, new strategies which will help to close the gap will be designed. In the end, it is concluded that; (1) irrigation efficiency is the leverage point of the system and by increasing it from 40% to 45% we can significantly remedy the problem (2) no single solution can solve the crisis and several policies should be adopted simultaneously
