The potential for organic farming (OF) as a system that enhances climate change (CC) adaptation and improves food security in Africa has been a provocative topic in global discussions. Although OF is promptly increasing globally, the pertinent question is to figure out how OF can result in sustainable food production systems. This systematic literature review was undertaken through two database searches to maximize available data and relevant literature (Scopus and Wiley Online Library), resulting in 2069 documents published between 2007 and 2022. After excluding documents that were duplicates, not presented in English and irrelevant, 538 documents remained. From the remaining documents, 406 were excluded after careful review (not meeting at least one of the inclusion criteria), and 132 documents remained. Finally, 95 documents were excluded after assessing and reviewing full-text articles for eligibility. As a result, 37 documents were included (eligible) in the systematic review. The inclusion criteria followed in this study considered language, thematic focus and document type. The reviewed articles suggest that OF can be one of the climate change adaptation options, preserve environmental impact and improve food security. However, the relative performance in OF differs from region to region. Correspondingly, the organic-conventional yield gap mostly depends on crops and cropping practices. This review concludes the prospects of organic agriculture in Southern Africa are still largely untapped, particularly by smallholder farmers who remain uncertified. Therefore, the review recommends organised interventions on various fronts, starting with organic certification and regulation. Accordingly, sustainability (economic, environmental and social) and investments in OF need to be reinforced and promoted by stakeholders, as it has the potential to alleviate the swarming farming challenges posed by climate change and to address food insecurity.
