چکیده

به منظور عرضه مطمئن آب و رعایت اولویت‌های تخصیص مختلف، نیاز به برنامه‌ای دقیق و کامل است. در این مقاله تخصیص منابع آب یک حوضه آبریز با استفاده از دو روش تخصیص عمومی و تخصیص مبتنی بر بازار آب مورد توجه قرار گرفته است. منطقه مورد مطالعه در این تحقیق، حوضه آبریز بالخلی‌چای در استان اردبیل می باشد. ابتدا با هدف مدل‌سازی تخصیص عمومی، با استفاده از یک مدل بهینه‌سازی غیر خطی، سود خالص کشاورزان با تعیین سطح زیر کشت محصولات هر منطقه و همچنین مقدار آب تخصیص یافته بهینه به هر یک از مناطق محاسبه شده است. در مرحله دوم، برای تخصیص بازار آب، مدل بهینه‌سازی با تابع هدف ارزش اقتصادی آب و با وجود امکان مبادله حقابه‌ها توسعه داده شده است. پس از تخصیص آب، برای رعایت عدالت و تشکیل بازار پایدار، باید پرداخت‌هایی بین شرکت‌کنندگان صورت گیرد. برای بازتخصیص سود حاصل از تشکیل بازار از مفهوم ارزش شاپلی استفاده شده و با تشکیل ائتلاف‌های مختلف، سود حاصل از برقراری بازار بصورت عادلانه توزیع شده است. حجم مبادلات مناطق و مقادیر آب اختصاص‌یافته نهایی، متغیر‌های مدل می-باشند. با تشکیل بازی همکارانه، سود کلیه مصرف‌کنندگان با تشکیل بازار افزایش خواهد یافت. بر اساس نتایج این تحقیق، تشکیل بازار آب در منطقه بالخلی‌چای با انتقال آب به مصارف با ارزش سایه‌ای بالاتر، می‌تواند سبب افزایش بهره‌وری مصرف آب گردد. بر اساس نتایج، با تشکیل بازار در منطقه مورد مطالعه، امکان مبادله 18 درصد حقابه‌های تخصیص‌یافته فراهم می‌گردد که این حجم مبادلات، سبب افزایش در حدود 9 درصد سود می شود.

چکیده [English]

In order to supply reliable water, to prioritized demands, a comprehensive plan is needed. In this paper, the allocation of water resources in a basin is evaluated using two methods of administrative and market-based mechanisms. The study area is Balikhlichay river basin in Ardabil province. First, in the administrative allocation, a nonlinear optimization model has been developed to maximize the net benefit of farmers, taking into account the system constraints. At this stage, the area of crops, the optimum amount of water and the shadow prices are in each region have been obtained. Secondly, in the market-based allocation, optimization model has been developed by maximization of the economic value of irrigation water and defining tradable water rights. In order to reallocate the market benefits and establish a sustainable market, the concept of the cooperative game and Shapley value is then utilized. The benefits of the market are equitably distributed in a different coalition of consumers. The volume of water trades and the final allocated water are decision variables. The benefits of all consumers in the market will increase by cooperative game. Results indicate that water market in the Balikhlichay region can improve water use efficiency. The results show that the market leads to trading about 18% of water rights among farmers in this region. Additionally, the results obtained in this paper show that the market would increase farmers profitability by to 9%.
