Deep decarbonization options for the agriculture, forestry, and other land use (AFOLU) sector in Africa: a systematic literature review

Greenhouse gases (GHG) emanating from agriculture, forestry, and other land use (AFOLU) sector are among top contributors to anthropogenic climate change in Africa and globally. Minimizing AFOLU sector GHG emissions in Africa is notoriously hard because of difficulties in emission estimation, the disperse nature of AFOLU emissions, and the complex links between AFOLU activities and poverty reduction. Yet, there are very few systematic reviews dealing with decarbonization pathways for the AFOLU sector in Africa. This article explores the options for achieving deep decarbonization of AFOLU sector in Africa, through a systematic review. Using the method of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA Statement), 46 studies of interest were selected from the databases of Scopus, Google Scholar, and Web of Science. Four sub-themes were identified from the critical review of the selected studies covering key decarbonization approaches used in AFOLU sector. The literature suggests that while forest management and reforestation reduction of GHG in animal production and climate-smart practices in agriculture hold great promises for AFOLU sector decarbonization in Africa, there appears to be very limited coherent policy in the continent addressing any of these AFOLU sub-sectors.
