چکیده

اکو- بهره‌وری در توسعه پایدار، به صورت عملکرد زیست‌محیطی یک محصول کشاورزی با توجه به ارزش آن محصول تعریف می‌شود. نرم‌افزارهای SEAT و EVAT، دو ابزار مدل‌سازی هستند که با ترکیب دیدگاه‌های اقتصادی و زیست‌محیطی در یک مدل واحد تحلیل می‌شوند و به کاربر این امکان را می‌دهد تا سیستم مصرف آب را ارزیابی کند. در این مطالعه، شاخص اکو- بهره‌وری با توجه به اثرات زیست‌محیطی مصرف سوخت‌های دیزلی در یکی از واحدهای عمرانی شبکه آبیاری و زهکشی سفیدرود مورد بررسی قرار گرفت. اراضی کشاورزی این منطقه شامل شالیزارهای برنج، باغات چای و استخرهای پرورش ماهی است. عملکرد زیست‌محیطی سیستم آبی منطقه برای پدیده تغییر اقلیم ایجاد شده در اثر انتشار گازهای گلخانه‌ای ناشی از مصرف سوخت‌های دیزلی ارزیابی گردید، در حالی‌که عملکرد اقتصادی آن با استفاده از کل ارزش افزوده محصولات نهایی سیستم و با توجه به مصرف آب و روش‌های مدیریتی مورد استفاده اندازه‌گیری گردید. نتایج نشان داد که مقدار این شاخص در شرایط پایه منطقه مورد مطالعه برای شالیزارهای برنج، باغات چای و استخرهای پرورش ماهی به ترتیب Milion Rials/kg 〖CO〗_2 eq 46/3، 76/0 و 02/0 بدست آمد. در ادامه، سناریوهایی در راستای بهبود شاخص اکو-بهره‌وری تعریف و مورد ارزیابی قرار گرفت. نتایج نشان داد که از بین سناریوهای تعریف شده سناریوی 3 (63 درصد راندمان آبیاری و 5 درصد مصرف آب برگشتی در شالیزارهای برنج) و سناریوی 4 (جایگزینی نیمی از ماشین‌آلات دیزلی با برقی در استخرهای پرورش ماهی) باعث افزایش 17 و 86 درصدی شاخص‌ اکو-بهره‌وری کل سیستم آب کشاورزی واحد عمرانی F1 شده است.

چکیده [English]

The concept of eco-efficiency is used as a tool to analyze farm sustainability to relate economic value of an activity to its impact on the environment. SEAT and EVAT software are two modelling tools which combine both economic and environmental viewpoints into a single modelling framework and allow the user to evaluate the water consumption system. In this research, the eco-efficiency index with regard to the environmental impacts of diesel fuel was evaluated in the one of commands area in Sefidroud Irrigation and Drainage. The agricultural lands in this area including paddy rice, tea-garden and fish-culture. The environmental performance of the system was evaluated for climate change due to greenhouse gas emissions from diesel consumption as well the economic performance was measured by using the total value added to the system's final products due to water use and the adopted management practices. Then, the value of area vulnerability was assessed according to eco-efficiency index of climate change. The results showed that the eco-efficiency index in baseline for paddy rice, tea-garden and fish-culture were calculated 3.46, 0.76 and 0.02 Milion Rials/kg 〖CO〗_2 eq, respectively. the results showed that eco-efficiency indicator of scenarios 3 (the percent of irrigation efficiency and return flow are 63% and 5% in paddy rice, respectively) and 4 (replacing 50% of diesel engines with electric motors in fish farming) were increased 17 and 86% in the entire of F1, respectively, in comparison with base scenarios.
