چكيده فارسي :
در دهه‌هاي اخير تقاضا براي آب بويژه در مناطق خشك و نيمه‌خشك افزايش يافته است و باعث افزايش بهره‌برداري از اين منابع شده است. منابع آب زيرزميني از منابع مهم تأمين آب براي مصارف در بخشهاي مختلف از جمله شرب، صنعت و كشاورزي است. امروزه استفاده بيش از حد از منابع آب زيرزميني، فشارهاي وارده بر اين منابع را افزايش داده و پيامدهاي محيطزيستي جبران‌ناپذيري را سبب شده است. در اين مطالعه از يك مدل نظريه بازي همكارانه جهت بررسي نحوه همكاري ميان بهره‌برداران از منابع آب زيرزميني با هدف مطالعه خسارت محيطزيستي و سود ذينفعان استفاده شده است. مدل استفاده شده در اين مطالعه براي بررسي يك مسئله كنترل بهينه شامل مباحث اقتصادي، محيطزيستي، كشاورزي و متغيرهاي هيدرولوژيكي توسعه داده شده است. جهت تعريف و حل مسئله شبيه‌سازي - بهينه‌سازي بصورت منعطف‌تر در اين مطالعه، از روش بهينه‌سازي جامعه مورچه‌ها استفاده شده كه امكان تمركز بر گستره متنوع‌تري از اهداف و قيود را فراهم مي‌نمايد. نتايج نشان مي‌دهد كه چگونه برداشت‌هاي بي‌رويه و كنترل نشده در هر آبخوان بر روي ساير ذينفعان از منابع آب‌زيرزميني كه در مجاورت آن آبخوان قرار گرفته‌اند، تأثير مي‌گذارد. همچنين، اثرگذاري بر روي اكوسسيتم‌هاي آبي نيز مورد بررسي قرار گرفته و نتايج آن به صورت خسارت محيطزيستي ارائه شده است. نتايج مطالعه نشان مي‌دهد كه در حالت تشكيل ائتلاف و همكاري مؤثر ميان ذينفعان در نواحي مختلف و در نظر گيري پيامدهاي محيطزيستي، خسارات محيط زيستي نسبت به شرايط وضع موجود كاهش مي‌يابد.

In the recent decades, water demand has been increased specially in arid and semi-arid areas, led to the over-exploitation of water resources. Groundwater resources are important sources of water supply for domestic, industrial and agricultural consumption. Nowadays, over-exploitation from groundwater resources has increased the pressure on these sources which causes the major environmental damages. In this study, a cooperative game theory model is used to investigate how the cooperation of groundwater resources consumers influences the environmental damage and the benefit of stakeholders. The used model in the present study is developed for investigation of an optimal control problem including the variables of economic, environmental, agronomic, and hydrologic issues. Ant colony optimization method is used to flexible define and solve the simulation-optimization problem of this study which provides an ability to consider an extensive range of objectives and constraints. The results show that how uncontrolled pumping and over-exploitation in each aquifer affect on the stakeholders of the adjacent aquifers. Furthermore, the impacts on aquatic ecosystems are analyzed and presented as environmental damages. The obtained results demonstrate that in different areas, environmental damages are reduced under the coalition and effective cooperation condition among stakeholders and considering the environmental externalities in comparison with status quo.
