A methodology for greenhouse gas emission and carbon sequestration assessments in agriculture
Grewer, et al.
This paper presents methodology used to estimate impacts of agricultural interventions on greenhouse gas (GHG) emissions and carbon sequestration. This methodology is used in an analysis of several development projects supported by USAID. The methodology allows users to estimate GHG impacts at project scale, GHG emissions by agricultural practice and GHG emissions per unit of output (i.e., GHG emission intensity). In the paper, the presented approach is a rapid assessment technique that is well suited to provide an indication of the magnitude of GHG impacts and to compare GHG impact strength of different field activities or cropping systems.
The paper concludes that investments in sustainable food systems provide opportunities for reducing future increases in GHG impacts from a growing global population and changing consumption patterns. Data intensity, technical complexity, and cost implications function as important barriers for integrating GHG assessments within investment decisions and policy-making. The presented method presented allows for the assessment of GHG impacts under data scarcity, using a guided methodological process of reduced technical complexity.
