Climate change is a major constraint to the progress of Africa’s agriculture, food, and nutrition security; its effect is tied to geographical position and driven by the limited adaptive capacity of the agricultural households. The most vulnerable stakeholder group are the smallholder farming households with limited resources and knowledge of adaptation and mitigation techniques. Sub-Saharan Africa owns more than 60% of the world’s arable land with over 85% of the farmers being smallholder farmers, who are predisposed to various risks. This paper analyzes the adoption of climate-smart agriculture (CSA) processes and technologies by smallholder farming households in Sub-Saharan Africa. The study used mixed methods and an integrative literature review. This review indicated that the knowledge of CSA technologies by smallholder farmers in Africa is increasing and, thus, concerted efforts to continuously generate CSA technology would contribute to the desired positive outcome. To accelerate the pace of adoption and use of the technologies, the linkage of farmers, researchers, and extension practitioners is needed. Measures should also be put in place to ensure that CSA actions are implemented using bottom-up approaches.
