Abstract: Traditional African vegetables (TAVs) are an important component of an ecologically sustainable approach to addressing food and nutrition security in Africa. This review aims to identify the scope of the knowledge translation literature that exists across multiple aspects of the TAV value chain and to identify gaps in knowledge translation research. A scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was conducted. The Population, Concept, and Context (PCC) framework was used to guide the development of inclusion and exclusion criteria for this review. The Web of Science, Scopus, Science Direct, and ABI/Inform databases were searched to identify the relevant studies which were then screened using the Covidence 2024 online software to select studies and extract information for analysis and reporting. A total of 182 studies/articles were selected and examined. The most significant knowledge documented about TAVs pertains to their vast genetic diversity contributing to their rich nutritional and medicinal properties, their ability to withstand harsh environmental conditions such as drought, pests, and diseases, as well as the effects of various post-handling techniques on the nutrient content of TAVs, with the production phase of the TAV value chain being the most studied. This review found that, although a breadth of knowledge about TAVs has been generated, there is still little documentation about transferring and utilizing this knowledge across the TAV value chain. This review identified that more research is needed to document the strategies and practices for the transfer and utilization of knowledge to ensure that it is utilized to enhance nutritional outcomes across Africa.
