The slow adoption of new agricultural technologies is an important factor in explaining persistent productivity deficits among smallholders in Sub-Saharan Africa (SSA). Farmers delay in particular the uptake of technology packages. Since knowledge constraints are an important barrier to adoption, effective extension approaches are key. In recent decades, extension systems in many SSA countries have moved towards decentralized “bottom-up” models involving farmers as active stakeholders.
If the world is to transition towards agrifood systems that are more sustainable and equitable, small-scale production systems will be key to progress. Large parts of the world depend on small-scale systems for maintaining food security and nutrition (Lowder, Sánchez and Bertini, 2021; Herrero et al., 2017). Despite this centrality, neither small-scale production systems nor small-scale producers have received due recognition under predominant agrifood systems paradigms.
