Energy consumption and CO2 emissions in rainfed agricultural production systems of Northeast Thailand

Potential greenhouse gas emission reductions in soybean farming: a combined use of Life Cycle Assessment and Data Envelopment Analysis

“…kg À1 ). Our data on soybean confirmed the results reported by other authors (Pelletier et al, 2008;Soni et al, 2013) showing the importance of the field emissions as the main contributor to the global warming assessment.…”

Energy efficiency of rice production in farmers’ fields and intensively cropped research fields in the Philippines

“…In both the canal irrigated rice studied by Bautista and Minowa (2010) and in the current study manual labour exceeded 300 person h ha −1 , but accounted for less than 3% of the total AEI. The energy efficiency of Laguna Province rice production is also similar to the rainfed transplanted rice described by Soni et al (2013) in which the AEI and NEY p were 8 GJ ha −1 and 12 GJ Mg −1 , respectively.…”

Optimization of energy required and greenhouse gas emissions analysis for orange producers using data envelopment analysis approach

“…In this study, assessment of GHG emissions comprises two major groups of emission sources, namely (a) production, transportation, storage and transfer of agricultural chemicals (Lal, 2004;Soni et al, 2013), (b) GHG emissions from fossil fuel combustion (Lal, 2004;Soni et al, 2013). The standard coefficients were applied to computation of GHG emissions for above items ( Table 2).…”

“…ha À1 , respectively. Also, Soni et al (2013) presents the energy inputeoutput analyses of different agricultural activities and fresh pond culture (polyculture). Results reveal noticeable variations in energy consumption and CO 2 emissions from various agricultural production activities.…”
