There are several research gaps in food and nutrition security across Africa according to the document. Key gaps include a substantial duplication of research effort, research not being adequately linked to local priorities, and research being driven more by external parties rather than the local policy and research community. Additionally, there is limited evidence on nutrition issues like women's and adolescent's nutrition, dietary behaviors, and how to effectively scale up proven nutrition-sensitive interventions. Addressing these gaps will require better coordination of research efforts, a focus on understanding differences at subnational levels, and leadership to manage cross-sectoral food and nutrition security research within countries.
