| Description | Problem context
Converting land from natural to agricultural use is generally associated with a decline in soil organic carbon. Carbon sequestration in agricultural land is therefore seen as one way in which the agricultural sector can contribute to climate change mitigation. Results obtained in this regard tend to vary broadly, depending on multiple factors such as climatic conditions, soil type, soil depth and time span considered, and technology applied. Whereas multiple meta-analyses exist for restoration measures such as agroforestry, cover crops and reduced and no-till systems, there is no systematic review of the effects of cross-slope barriers such as soil bunds and terraces on soil carbon sequestration. Research Objective/Question What is the effect of cross-slope barriers on soil carbon sequestration, and is this effect sensitive to factors such as climate, soil type, soil depth, and time? The objective of this study is to systematically review the available evidence for this question. What is expected from the student (type of research) Build upon an initial analysis and conduct a global meta-analysis based on published papers and other sources. The activities will consist of querying research databases, literature review to extract measured data, statistical analysis and writing up of the results. |
