低温室气体排放（GHG）农业可能吗？事实上，这是可取的吗？为了寻找这两个基本但极其相关的问题的答案，本研究考察了当前的农业实践，并将长期田间试验的科学数据库作为低温室气体农业的案例研究。此外，该研究还探讨了实现低温室气体农业系统所需的变化。它还阐明了农业生态耕作系统方法的适应能力，利用科学文献中的有机系统案例研究。每年，农业排放的温室气体占估计总排放量的10%至12%，约为每年5.1至6.1亿吨二氧化碳当量。Smith等人（2007）和Bellarby等人（2008）提出了减缓温室气体排放的方案，发现农民和政策制定者都将面临农业所需的与温室气体相关的变化的挑战。需要改进的领域包括增加免耕种植、农林复合、作物和动物综合养殖的使用，以及减少粮食和农业外部投入的使用。在这些努力中，有机农业所提供的技术是值得考虑的。
Is low greenhouse gas emission (GHG) agriculture possible? Is it, in fact, desirable? In seeking answers to these two basic but extremely relevant questions, this study examines current farming practices, and incorporates scientific databases from longterm field experiments as case studies for low GHG agriculture. Further, the study examines the changes that will be needed for low greenhouse gas agriculture systems to become a reality. It also elucidates the adaptive capacity of agro-ecological farming system approaches, using organic system case studies from the scientific literature. Each year, agriculture emits 10 to 12 percent of the total estimated GHG emissions, some 5.1 to 6.1 Gt CO2 equivalents per year. Smith, et al. (2007) and Bellarby, et al. (2008) have proposed mitigation options for GHG emissions, finding that both farmers and policymakers will face challenges from the GHG-related changes needed in agriculture. Areas for improvement include increased use of no-till cropping, agro-forestry, and integrated crop and animal farming, and decreased use of external inputs in food and agriculture. The techniques offered by organic agriculture are valuable for consideration in these efforts.
