Abstract

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. The practical concept of eco-efficiency is used according to the method of irrigation, the conveyance of water in agricultural fields, the environmental effects of crop productions and the ECONOMIC value of the crop yield. SEAT and EVAT software are two modeling tools which combine both ECONOMIC and environmental viewpoints into a single modeling 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 one of command areas in Sefidroud Irrigation and Drainage Network. The agricultural lands in this area include paddy rice, tea-garden, and fish-culture ponds. The environmental performance of the system was evaluated for climate change due to greenhouse gas emissions from diesel consumption while the ECONOMIC performance was measured by using the total value added to the system's final products in relation to the water used and the adopted management practices. Then, the vulnerability of the area was assessed according to eco-efficiency index of climate change. The results showed that the eco-efficiency index in the baseline for paddy rice, tea-garden and fish-culture were calculated as 3. 46, 0. 76 and 0. 02 Million Rials/kg CO2 eq, respectively. The results showed that eco-efficiency indicator for scenarios 3 (where the paddy rice percent of irrigation efficiency and return flow recycling were considered as 63% and 5%, respectively) and 4 (by replacing 50% of diesel engines with electric motors in fish farming) were increased respectively by 17 and 86% overall in F1 unit, in comparison to the base scenarios. Therefore, to improve the eco-efficiency indicator concern should be given to the management of the agricultural water system, replacement of the diesel engine pumps with electric pumps for groundwater abstraction, adopting new water pricing policies, and increase in the degree of agricultural mechanization.
