“…According to IPCC (1996), GWPs of CO 2 , CH 4 , and N 2 O (over a time horizon of 100 years) can be respectively considered as 1, 21 and 310. Thus, GWI of agricultural production can be calculated through multiplying global warming potentials (GWP) by the amount of GHG emissions (Yousefi et al 2014):…”

Agriculture plays a central role in maintaining food security and achieving sustainable development for human society. It is a challenge for the agricultural sector to mitigate greenhouse gas (GHG) emissions and maintain agricultural production. However, dual-level uncertainties exist in the processes of agricultural GHG accounting and emission reduction management. In this research, an integrated approach for identifying adaptation strategies in agricultural GHG emission reduction management was developed through incorporating life cycle analysis (LCA) of agricultural production into a general mathematical programming model. This approach strengthened the applicability of LCA and the comprehensiveness of programming models in generating agricultural adaptive actions under different GHG emission restriction targets. Also, dual-level uncertainties of LCA and adaptation management can be effectively addressed. A case study was proposed to illustrate application of the approach in Dalian City, China. The results indicated that farming patterns in eight districts would change significantly. The total area of maize fields would account for the primary proportion (i.e., 40-45 %) in its agricultural sector. Rice, peanut and cabbage fields would be the minor contributors in terms of GHG emissions. In addition to effective rainfall (i.e., [156, 259] mm/ha), a certain amount of water would be supplied for agricultural irrigation to maximize the city's agricultural yields. Compared with other agricultural crops, rice fields would need the largest amount of irrigation water (i.e., [153.72, 277.98] Mt) to meet the requirements of local government plans.

“…As crops are a major consumer of the atmospheric CO 2 , carbon sequestration analysis can also be a useful tool in assaying the environmental impacts of crop production [25]. In this regard, carbon sequestration, GHG emissions, and energy use efficiency of sugar beet production in western Iran were studied by Yousefi et al [26], who reported that the highest share of input energy was for nitrogen fertilizer, electricity, diesel oil, and water for irrigation, respectively. It has been also noted that the sugar beet can be affective for carbon sequestration in agro-ecosystems.…”

The aim of this study was to investigate the non‐renewable energy use efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of groundnut sole cropping and groundnut‐bean intercropping agro‐ecosystems. Data were collected from 136 farmers using face‐to‐face questionnaires in the Kiashahr region of northern Iran. The results analysis suggested that the non‐renewable energy ratio of groundnut‐bean intercrop agro‐ecosystem (6.03) was greater than that of groundnut sole cropping system (4.59). The highest share of non‐renewable energy belonged to diesel fuel, which was followed by the nitrogen fertilizer for both systems. This demonstrates the importance of fossil fuel and N fertilizer use management in both agro‐ecosystems. The total GHG emissions from groundnut and groundnut‐bean intercrop agro‐ecosystems were computed as 636.14 and 657.36 kgCO2eq ha−1, respectively. The highest impact of GHG emissions was from diesel fuel within both farming systems, confirming the prominent role of the fossil fuel input again. The carbon efficiency for groundnut‐bean intercrop agro‐ecosystem (14.78) was greater than that of the groundnut sole cropping system (11.14). Therefore, groundnut‐bean agro‐ecosystem can be observed to be more effective for carbon sequestration. The use of greater amounts of biological resources helps to improve the efficiency of energy use and mitigation of GHG emissions in both agro‐ecosystems. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1832–1839, 2017

“…Efficient use of energy in agriculture will minimize environmental problems, prevent destruction of natural resources and serve to promote sustainable agriculture as an economical production system Erdal et al, 2007). The relation of energy input and energy output in the agroecosystems have been investigated by many researchers for many crops such as sugar beet (Asgharipour et al, 2012;Yousefi et al, 2014), tomato (Rezvani Moghaddam et al, 2011), pulses (Koocheki et al, 2011) and cotton (Zahedi et al, 2014).…”

a b s t r a c tEfficient use of energy in agroecosystems will reduce environmental problems, prevent destruction of natural resources and serve to promote sustainable agriculture as an economical production system. The aim of this study was to investigate the energy use efficiency in four double cropping systems including: wheat-silage corn (W-SC), barely-silage corn (B-SC), barely-grain corn (B-GC) and barely-rice (B-R) in the arid regions of Isfahan province, Iran. Data used in this study were collected from 73, 45, 38, 18, 18 wheat, barley, silage corn, grain corn and rice farms, respectively, personal interview using semistructured questionnaire during 2010. The results indicated that the total energy consumed were 140,422, 128,979, 121,360 and 172,962 MJ ha −1 for the W-SC, the B-GC, the B-SC and the B-R cropping systems, respectively. The share of diesel fuel by 43.36% (W-SC), 43.93% (B-GC), 42.82% (B-SC) and 49.40 % (B-R) was the highest input. This was followed by fertilizer (W-SC: 24.70%, B-GC: 25.12%, B-SC: 27.05 and B-R: 16.11) and water (W-SC: 10.54%, B-GC: 11.76%, B-SC: 10.73 and B-R: 13.85), respectively. The energy use efficiency was found as 1.70 for W-SC, 1.65 for B-GC, 1.64 for B-SC and 1.03 for B-R double cropping systems, respectively. According to the research results the W-SC, B-SC, B-GC and B-R double cropping systems were more efficient in terms of energy, respectively.
