In the last three decades, agrifood value chains (AVCs) have expanded and transformed in developing regions. AVC transformation across Africa has created huge markets for farmers, along with employment in various supply chain segments, including food processing, wholesaling, and logistics provision. Thereby, domestic food supply chains dominate Africa's food supply and SMEs move most of this food. Understanding these SMEs and their behaviours is important to be able to design policies and programs with positive impacts on food and nutrition security. This raises the question on whether the expansion of SMEs along Africa's food supply chains can improve food and nutrition security.
