ABSTRACT: In most rural areas of Africa, where other advanced forms of media may not be accessible, radio is typically the most widely used means of communication. This review assessed the effectiveness of radio-based interventions in promoting Climate-Smart Agriculture (CSA). A total of 152 records were identified through strategic searches on Scopus, Taylor & Francis Online, African Journals Online, and Google Scholar. Following screening and eligibility assessment, 13 studies met the inclusion criteria. Data extraction was systematically conducted, and the quality of the included studies was appraised using an adapted checklist. The review revealed that radio programmes consistently improved farmers’ understanding of CSA practices. Farmers responded more positively when programmes were interactive, trustworthy, and aligned with their daily challenges. When the information farmers received from the radio was combined with other extension methods, such as field visits and group discussions, the farmers were more likely to adopt CSA practices. The key barriers identified included weak or inconsistent radio signals, insufficient funding, and inadequate institutional support for community radio. The review concludes that radio is an effective and practical means of promoting CSA practices in Africa.
