Investigating the energy consumption and carbon footprint in mung bean production ecosystems in Iran

Energy consumption is one of the main issues in production systems because of the role in production costs and environmental impacts. The present study was conducted to investigate the environmental aspect of mung bean farms in the ۲۰۲۲-۲۰۲۳ crop year. The required data were collected through questionnaires and face-to-face interviews with ۷۸ mung bean farmers in Darehshahr, Ilam, Iran. Input-output materials were calculated and based on them material and energy indicators and carbon footprint were calculated. The results showed that the carbon footprint of mung bean production was ۲.۷۴ ton CO۲ eq.ha-۱ (۲.۴۲ kg CO۲ eq.kg-۱). The total amount of input and output energy in mung bean production was ۱۲۵۸۶.۴۹ and ۱۶۶۰۴.۴۰ MJ.ha-۱, respectively. The most important energy-intensive inputs in mung bean production were nitrogen fertilizer, fuel, and electricity with the shares of ۳۲.۵۷, ۲۵.۸۸, and ۲۴.۴۳%, respectively. The values of energy efficiency, productivity, intensity, net gain, and net gain efficiency were ۱.۳۲, ۰.۰۹ kg/MJ, ۱۱.۱۱ MJ/kg, ۴۰۱۷.۹۱ MJ/ha, and ۰.۳۲ MJ.MJ-۱, respectively. Given the low share of renewable energy (۳.۴۹%), increasing renewable energy consumption is necessary in mung bean production.
