| Based on the principles of hierarchy, representativeness, operability and completeness, 10 indices are selected from 3 aspects of resource consumption, energy consumption and environmental emissions during small town development. Comprehensive evaluation index system for industrial source-energy saving and pollution reducing in small towns in constructed. According to the fuzzy mathematical method, qualitative calculation model of two-level hierarchical structure is constructed. Among them, the first-level model focuses on each specific evaluation index. It calculates the membership degree of region to resource-energy and pollution reducing in evaluation index set, and sorts the calculation results. The second-level model focuses on the first-level... |

| Due to good climate condition and large cultivation area in Mazandaran province of Iran, orchard commodities products, especially orange production is widely improved in this region. In this study, Data Envelopment Analysis (DEA) technique was used to analyze the efficiency of farmers, discriminate efficient orchards from inefficient ones and to identify wasteful uses of energy for orange producers in Sari region. Data were collected using face-to-face surveys from 86 orange orchardists and included the human power, machinery, diesel fuel, chemicals, fertilizer, farmyard manure, water for irrigation and electricity input sources used per hectare of orange production. The data was organized and analyzed by DEA Techniques. The results revealed that the... |

| The nonparametric method of data envelopment analysis (DEA) was used to investigate the energy efficiency and CO2 emission of barley farm in Hamedan province of Iran. The method was used based on eight energy inputs including human labor, machinery, diesel fuel, fertilizers, farmyard manure, biocide, electricity and seed energy and single output of barley yield and technical, pure technical, scale and cross efficiencies were calculated using CCR and BCC models. The results showed that the average values of technical, pure technical and scale efficiency scores of farmers were 0.788, 0.941 and 0.833, respectively. Also, energy saving target ratio for barley production was calculated as 11.45%, indicating that by following the recommendations of this... |

| Grape fruit production has increasing rate in recent years. In this study a non-parametric method of Data Envelopment Analysis (DEA) has used to estimate the energy efficiency of grape fruit production orchards in Sari region of Iran. Additionally, the impacts of energy inputs on grape fruit yield were determined. Data were collected using a face-to-face questionnaire method from 71 orchardists in winter 2014. The results showed that the total energy consumption was 49.8 GJ ha–1 and chemical fertilizers by 28% of this quantity had highest share on total input energy. The results of CCR and BCC models of DEA showed that from total of 71 orchardists, only 21 orchards were technical efficient by efficiency score of 1 and 43 orchards were pure technical... |
