Many Sub-Saharan African economies heavily rely on agriculture, which has been under several shocks and consequently has resulted in low productivity that has caused food insecurity. In particular, the nexus between credit access and agricultural productivity, however, is still poorly understood. This paper carried out Preferred Reporting Items for Systematic Reviews and Meta-Analyses on 26 carefully chosen published items and estimated the overall effects of credit access on agricultural productivity in sub-Saharan Africa. The use of PRISMA 2020 criteria is where our study breaks. The search strategy to identify relevant articles for the review was done on online scholarly databases Google Scholar, Science Direct, Africa wide Knowledge, and the AGRIS open database,through the use of keywords like “Credit access AND Agricultural Production” OR “Agricultural productivity” OR “Agricultural product*” AND “Sub-Saharan Africa” .The random effect model and meta regression analysis were applied to show the effect of credit access on agricultural productivity. The model output showed that access to credit increases agricultural productivity adoption by 0.96 unit, as compared to farmers who have no access to credit. The meta-analysis suggests that agriculture is more exposed to credit constraints than other (non-agricultural) sectors, ceteris paribus, with an overall pooled association effect size for credit access and agricultural productivity of 0.96 (95% CI, 0.84–1.09; P = 0.00) and significant heterogeneity between studies (Ι2 = 83%, P < 0.000).Future reviews and meta-analyses increasingly focusing on methodological details are recommended to provide insights on credit access effects on sub-Saharan African agricultural productivity, which is mainly responsible for food security in the region. Policy implications and prolonged credit effects on agricultural productivity in sub-Saharan Africa are then contemplated.
