“…1). Results of other studies (AghaAlikhani et al 2013;Bautista and Minowa 2010;Bockari-Gevao et al 2005;Cherati et al 2011;Kazemi et al 2015;Pishgar-Komleh et al 2011) confirmed that the fuel input has an important and effective share among all types of energy used for the paddy production. Kazemi et al (2015) reported that the high fuel consumption in agricultural systems of Iran is due to two main reasons: old machineries and irrigation pumps.…”

“…Therefore, increasing the annual yield of paddy production and/or reducing the energy usage, particularly diesel fuel energy and fertilizers, would help optimizing the rice agroecosystems energy consumption. Many researchers reported that applying sound farming management practices such as crop rotation and cultivating legumes improves energy use efficiency (Pishgar-Komleh et al 2011;Rathke et al 2007). In this study, there was a significant difference between women and men farmers with respect to farm size (P \ 0.05).…”

“…In terms of farm size effect on energy use efficiency, Iqbal (2007) and Nassiri and Singh (2009) indicated that small rice farms had the highest energy use efficiency and the lowest specific energy in comparison with other groups. Pishgar-Komleh et al (2011) reported that the largest farm size group had higher energy ratio compared with medium and small farms. Therefore, one of the main factors that affect the energy use efficiency in paddy production systems can be the farm size which is smaller for women farmers than men farmers.…”

“…In this sense, in Iran, where about 2.35 million tons of paddy were produced in 2014-2015, about 77.21% of the total paddy production is supplied by three Northern provinces (Gilan, Mazandaran, and Golestan) (Ministry of Jihad-e-Agriculture 2015), and based on informal statistics, more than half of the paddy labor is covered by women. However, previous studies about energy analysis of rice production (Alipour et al 2012;Cherati et al 2011;Pishgar-Komleh et al 2011) have ignored the effective role of women in this important crop production, while their practices in rice production systems with respect to many social, economic, and ecological issues are different. Therefore, the aim of this study is to probe the quantity of energy used for paddy production in female-headed and male-headed rice farms and the comparison of energy use pattern between them in Mazandaran Province of Iran.…”

“…Despite many attempts to specify the energy use efficiency in different agro-ecosystems (Bockari-Gevao et al 2005;Kazemi et al 2015;Keshavarz Afshar et al 2013;NabaviPelesaraei et al 2014;Pishgar-Komleh et al 2011;Rafiee et al 2010), the gap of gender perspective in this kind of analysis has not been filled yet. This ignorance happened while the role of women in crop production has been considered as the foundation of studies regarding women's participation in the development process since 1970s (e.g., Barrientos et al 2005;Birah et al 2016;Carr 2005;Egharevba and Iweze 2004;Jha 2004;Kerr et al 2007;Lope-Alzina 2007).…”

This study explores gender in the energy inputoutput analysis by comparing the energy indicators in paddy production in female-headed farms and male-headed farms during years of 2014-2015 in Mazandaran Province. Questionnaires were used to collect data from 120 paddy farmers (60 males and 60 females). Energy indicators were calculated for female-and male-headed farms. Results revealed noticeable variations in some important energy indicators between female-and male-headed farms. A significant difference was observed in terms of total energy input. The majority of energy input consumption for both female-and male-headed farms was devoted to diesel fuel, fertilizers, especially nitrogen fertilizers, and machinery. Results indicated that there was no significant difference between male-headed and female-headed farms in terms of net energy and specific energy, but energy use efficiency and energy productivity were significantly higher for female-headed farms. Then, it can be argued that gender factor had a significant impact on amount of direct, indirect, and renewable energy inputs. Based on our findings, female-headed rice systems were more efficient, where fossil-based inputs were used more environment friendly than male-headed farms. Finally, targeted ''soft'' policies like gender-sensitive capacity-developing program were proposed.

The objectives of this study were to investigate the relationships between energy inputs and yield, and to perform cost analysis for almond production. Data were collected by administering questionnaire in face‐to‐face interviews from procedures. The results showed that total energy input was 59,542.61 MJ ha−1 and the output was 25,190.13 MJ ha−1. The most important energy consuming inputs were electricity and chemical fertilizers with 55.98% and 17.72% of total energy input, respectively. The energy use efficiency and energy cost ratio values were estimated to be 0.42 and 0.19, respectively. The econometric model was developed using Cobb‐Douglas production function and the results revealed that human labor, machinery, chemical fertilizer, and farmyard manure energy inputs contributed significantly to yield. The results of sensitivity analysis of energy inputs showed the high impact of chemical fertilizers, and farmyard manure inputs on the yield. Economic analysis showed that the total production cost, total gross value, and net return of almond production were 5344.48 $ ha−1, 27,241.29 $ ha−1, and 21,896.81 $ ha−1, respectively. Also, productivity and the benefit to cost ratio were obtained to be 0.16 kg $−1 and 5.10, respectively. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 582–588, 2016

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
