Abstract

This systematic literature review examines the integration of circular economy (CE) practices within Sub-Saharan Africa's agri-food systems, a region confronting severe food insecurity, environmental degradation, and climate vulnerability. Using the PRISMA 2020 framework, the study analyzes 35 peer-reviewed publications to assess how CE principles can transform agricultural sustainability while identifying critical barriers and enablers to adoption. The review reveals significant theoretical debates surrounding CE implementation in Sub-Saharan African contexts. Key controversies include whether CE represents genuinely novel frameworks or repackages traditional cyclical farming practices, the appropriate scale for implementation between system-level and grassroots approaches, and the technology-access paradox where promoted high-tech solutions require infrastructure unavailable to most rural populations. Critical equity concerns arise regarding whether CE benefits reach vulnerable subsistence farmers or primarily advantage connected commercial operations. Empirical evidence demonstrates measurable CE benefits across the region. Case studies show waste reduction of 20 to 25 percent, crop yield increases of 15 to 20 percent, and farmer income improvements of 18 to 22 percent. Examples include Nigeria's biogas production, Kenya's composting programs, Rwanda's IoT irrigation systems, and Ethiopia's community cooperatives. Environmental benefits include 10 to 15 percent greenhouse gas emission reductions and enhanced soil health, while social impacts encompass improved food security and women's empowerment. However, substantial barriers constrain scalability including infrastructure deficits, knowledge gaps, financial constraints, policy fragmentation, and socio-cultural resistance. The analysis reveals that structural systemic constraints limit CE adoption more than individual farmer factors. Successful CE integration requires context-appropriate adaptation combining traditional knowledge with modern innovations through multi-scalar coordination. Establishing regional innovation hubs, harmonizing policy frameworks, scaling community cooperatives, investing in accessible technologies, and launching awareness campaigns is recommended. While CE offers transformative potential for addressing projected food demand increases, realization depends critically on coordinated multi-stakeholder approaches prioritizing equity alongside efficiency.
