چکیده

آب گرانبهاترین ثروتی است که در اختیار بشر قرارگرفته، امروزه جوامع بین­المللی از اهمیت آب در جهت داشتن رشد اقتصادی پایدار در زمان حال و آینده آگاه­اند. در این مطالعه، تأثیر کاهش منابع آب بر بخش های اقتصادی و زیرشاخه های کشاورزی از طریق یک مدل ماتریس حسابداری اجتماعی بررسی شد. نتایج آن در قالب آثار مطلق و نسبی ارائه شده­است. آثار و تبعات مستقیم و غیرمستقیم کاهش 10 و 50 درصد منابع آب منجر به کاهش تولید 4/3 و22 درصد از دید تقاضا کننده، 7/4 و 24 درصد از دید عرضه کننده برای محصولات کشاورزی شده است. از منظر تقاضا کننده کاهش منابع آب به میزان 10 درصد، 5/10درصد کاهش تولید در سایر بخش­های اقتصادی داشته است. آثار نسبی کاهش10 درصدی آب از منظر عرضه کننده نشان می­دهد که بیشترین کاهش مربوط به بخش­های آب و سایر معادن بوده است. کاهش نسبی منابع آب از منظر تقاضا کننده بیشترین تاثیر را بر بخش آب و دامپزشکی می­گذارد. از منظر آثار مطلق تقاضا کننده و عرضه کننده، میزان آسیب پذیری خانوارهای شهری ناشی از کاهش منابع آب بیش از خانوارهای روستایی بوده است. از منظر آثار نسبی عرضه کننده ، بیشترین تاثیر کاهش درآمد بر خانوارهای کم درآمد شهری از منظر تقاضا کننده مربوط به خانوارهای کم درآمد روستایی می­باشد.کاهش نسبی منابع آب از منظر تقاضا کننده بر روی عامل سرمایه تاثیر بیشتری از عامل کار دارد.

چکیده [English]

Water is one of the most valuable resources available to mankind. Today, international communities are aware of the importance of water for sustainable economic growth in the present and future. In this study, the effect of reducing water resources on economic sectors and agricultural sub-sectors was investigated through a social accounting matrix model. The results are presented in the form of absolute and relative effects. The direct and indirect impacts of a 10 and 50 percent reduction in water resources have been a decrease in the production of 3.4 and 22 percent from the viewpoint of a demanding, 4.7 and 24 percent from the viewpoint of a supplier, for agricultural products. From the perspective of a demanding, a 10 percent reduction in water resources has led to 10.5 percent production reduction of other economic sectors. The relative effects of 10 percent water reduction from a supplier’s point of view indicate that the greatest reduction was in water and other resources sectors. The relative reduction in water resources from the viewpoint of demanding has the greatest impact on water and veterinary sectors. From the perspective of the absolute effects on the demanding and the supplier, the vulnerability of urban households as a result of water resource reduction has been greater than that of rural households. Considering the relative impacts on a supplier, the impact of reduced income is greatr on urban low-income households than low-income rural households. Relative reduction of water resources from the perspective of demanding has a greater impact on capital factor than on labor factor
