This policy paper focuses on evidence-based interventions that strengthen agrifood systems by improving productivity, resilience, and market participation among smallholder producers. The analysis covers inputs and finance, irrigation infrastructure, midstream enablers (such as storage, processing, certifications, and producer organizations), and cross-cutting R&D interventions (including training, information and ICT, and innovation platforms). Evidence shows that individual interventions often have limited or short-lived effects when implemented in isolation. Instead, sustained impact depends on bundling complementary services, tailoring interventions to local contexts, and reinforcing delivery systems with inclusive, participatory institutions.
