国际气候变化专门委员会区分了农业部门缓解大气二氧化碳浓度的三个主要选择：(1)减少与农业有关的排放，(2)在土壤中建立和加强碳汇，以及(3)生产生物燃料以取代化石燃料。在目前关于需要减少大气中温室气体浓度的讨论中，审查了通过调整土地资源管理来持续固定土壤中碳的各种备选办法。通过重新造林和植树造林，加强大气二氧化碳在土壤中的固定，最终以稳定的腐殖质的形式，很可能被证明是比(暂时)将二氧化碳固定在现存量生物量中更持久的解决方案。这些行动还将有助于扭转土地退化的进程，从而促进有关区域人民的持续粮食生产和安全。
The International Panel on Climate Change distinguished three main options for the mitigation of atmospheric CO2concentrations by the agricultural sector: (1) reduction of agriculture-related emissions, (2) creation and strengthening of C sinks in the soil, and (3) production of biofuels to replace fossil fuels. Options for sustained sequestration of C in the soil through adapted management of land resources are reviewed in the context of the ongoing discussion on the need to reduce greenhouse gas concentrations in the atmosphere. Enhanced sequestration of atmospheric CO2in the soil, ultimately as stable humus, may well prove a more lasting solution than (temporarily) sequestering CO2in the standing biomass through reforestation and afforestation. Such actions will also help to reverse processes of land degradation, thus contributing to sustained food productivity and security for the people in the regions concerned.
