Agrarian Crisis and Steps to Combat It: Evidence of GHG Emission (CO₂) in Sesame Production in Jigawa State, Nigeria

Identifying sustainable and efficient broiler farms in the light of energy use efficiency and GHG emission reduction: data envelopment analysis approach

“…In the analysis of efficient and inefficient DMUs, the energy saving target ratio (ESTR) was used to specify the inefficiency level of energy usage for the DMUs under consideration. Following Sadiq et al (2015); Sadiq et al (2016), the formula is given Equation 6:…”

“…However, literature revealed recent studies which used DEA to estimate GHG emissions in crops production viz. Pishgar-Komleh et al (2012), Pishgar-Komleh et al (2013, Mohammadi et al (2013), Khoshnevisan (2013a), Khoshnevisan (2013b), Qasemi-Kordkheili and Nabavi-Pelesaraei (2014), Nabavi-Pelesaraei et al (2014), Sadiq et al (2015), Sadiq et al (2016). In the present study, the same methodology was adopted for broiler farms in Kaduna State, with the objectives to specify energy use for broiler production, segregate efficient farmers from inefficient ones, identify wasteful uses of energy inputs and investigate the effect of energy optimization on GHG emission in broiler production.…”

Pathways to Improve Energy Efficiency and Minimize Environmental Footprints of GHG Emission of Energy Inputs Used in Cowpea Production in Niger State of Nigeria

“…Moreover, results revealed that, the ESTR percentage for total energy input was 28.37%, indicating that by adopting the recommendations resulted from this study, on the average, approximately 28.37% (9138.96MJha -1 ) from total input energy in cowpea production could be saved without affecting the yield level. In related studies, Sadiq, et al [15] reported that 38.17% (1505.58MJha -1 ) of the overall inputs in sesame production in Jigawa State of Nigeria could be saved without affecting the yield level. Also, Avval, et al [8] found that 20% of overall resources in soybean production could be reduced if all of the farmers operate efficiently and the yield level will not be affected.…”

“…In the literature review, studies which applied DEA to investigate GHG emission reduction in agricultural units in different countries on crop production and animal husbandry are few, and examples of such studies are Komleh et al [12], Komleh et al [13], Khoshnevisan et al [5], Khoshnevisan et al [6], Soni et al [19], Pelesaraei et al [9], Kordkheili et al [14], Sadiq et al [16], Sadiq et al [15], Sadiq et al [17], Onuk et al [11], Singh and Mukhi [18], Carvalho et al [7] and Kyei et al [20].…”

Comparison of GHG emissions between efficient and inefficient broiler farms in Kaduna state of Nigeria using Data Envelopment Analysis (DEA): environmental sustainability

“…According to literature, the only study conducted on energy optimization in broiler production using DEA was done by Heidari et al [1]; with no effort of investigating the effect of energy optimization on GHG emission in broiler production. However, literature revealed few recent studies that used DEA to estimate GHG emissions in crops production [2][3][4][5][6][7][8][9][10]. In this study, the same methodology was adopted for broiler farms in Kaduna State, with the objectives to specify energy use for broiler production, segregate efficient farmers from inefficient ones, identify wasteful uses of energy inputs and investigate the effect of energy optimization on GHG emission in broiler production.…”
