Abstract

The increasing trend in use of agricultural inputs in recent years has resulted in the increase in ENERGY consumption and consequently increases in Green House Gas (GHG) emissions. Throughout the present study, the OPTIMIZATION of ENERGY use and thereby the reduction of greenhouse gas emissions in irrigated LENTIL production (in Esfahan Province) were investigated, using DATA ENVELOPMENT ANALYSIS (DEA) method. The data were, made use of, and randomly collected from 140 LENTIL producers using face to face questionnaire method in the cropping season of 2014-2015. Based upon two DEA models of Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS), the average values of technical efficiency, pure technical efficiency and scale efficiency were obtained as 0.960, 0.991 and 0.961, respectively. Through a consumption of optimum levels of inputs, the total ENERGY saving was estimated 1031 MJ/ha, i.e., 3.12% of the total ENERGY consumption, in which, irrigation water and nitrogen fertilizers contributed most to on the total ENERGY saving with the respective shares of 28% and 20%, total GHG emissions in actual reality vs optimum conditions were assessed as 930.45 and 882.17 kgCO2eq. per ha, respectively (5.18% reduction in total GHG emissions). Electricity and diesel fuel respectively contributed by 37% and 32% of total reduction to GHG emissions.
