This study examines the effect of cereal and livestock production-induced greenhouse gas emissions (GHGs) across high-, middle- and low-income countries from 2002 to 2016. A structural equation formulated within an environmental modeling framework is tested using the balanced panel-corrected standard errors estimation procedure. The findings showed that total food production is strongly correlated with methane and nitrous oxide in high-income countries and nitrous oxide emissions in middle-income countries. After disaggregating total food production into cereal and livestock production, the findings revealed that cereal production is positively and statistically significantly correlated with nitrous oxide emissions in high- and middle-income countries. The findings also confirmed that livestock production is positively and statistically significantly correlated with methane and nitrous oxide emissions in high-income countries. Incomes, industrial expansion, forest cover and education are other strong common determinants of GHGs in all three income categories of countries. The prime policy implication of this finding is the need for the food producers to transit toward environmentally cleaner and sustainable food production systems that mitigate GHGs and improve environmental performance and comply with the broader objectives of the United Nations Sustainable Development Goals 12, 13 and 15 (United Nations, 2015a, p. 3) relating to sustainable production, climate action and life on land, respectively.

高、中、低收入国家谷物和牲畜生产的温室气体排放

本研究考察了 2002 年至 2016 年高收入、中等收入和低收入国家谷物和畜牧业生产引起的温室气体排放 (GHG) 的影响。使用平衡面板测试了在环境建模框架内制定的结构方程-修正标准误差估计程序。研究结果表明,食品总产量与高收入国家的甲烷和一氧化二氮以及中等收入国家的一氧化二氮排放量密切相关。在将粮食总产量分解为谷物和牲畜产量后,研究结果表明,谷物产量与高收入和中等收入国家的一氧化二氮排放量呈正相关且具有统计学意义。研究结果还证实,畜牧业生产与高收入国家的甲烷和一氧化二氮排放量呈正相关且具有统计学意义。收入、工业扩张、森林覆盖和教育是所有三个收入类别国家的温室气体的其他共同决定因素。这一发现的主要政策含义是粮食生产者需要转向环境更清洁和可持续的粮食生产系统,以减少温室气体排放并改善环境绩效,并符合联合国可持续发展目标 12、13 和 15 的更广泛目标(联合国,2015a,第 3 页)分别与可持续生产、气候行动和陆地生命有关。工业扩张、森林覆盖和教育是所有三个收入类别国家的温室气体的其他共同决定因素。这一发现的主要政策含义是粮食生产者需要转向环境更清洁和可持续的粮食生产系统,以减少温室气体排放并改善环境绩效,并符合联合国可持续发展目标 12、13 和 15 的更广泛目标(联合国,2015a,第 3 页)分别与可持续生产、气候行动和陆地生命有关。工业扩张、森林覆盖和教育是所有三个收入类别国家的温室气体的其他共同决定因素。这一发现的主要政策含义是粮食生产者需要转向环境更清洁和可持续的粮食生产系统,以减少温室气体排放并改善环境绩效,并符合联合国可持续发展目标 12、13 和 15 的更广泛目标(联合国,2015a,第 3 页)分别与可持续生产、气候行动和陆地生命有关。
