Behavioral Approaches to Food Systems: Integrating Social and Behavior Change Communication for Safer, Healthier, and More Sustainable Practices

Transforming food systems begins not with messaging, but with people. However, persistent gaps exist between what vendors, farmers, and consumers know and what they do. These gaps are not only due to lack of awareness but are rooted in social norms, incentives, trust, time, and financial constraints, underscoring the need to rethink how research evidence is generated, valued, and applied. Traditional Social and Behavior Change Communication (SBCC), built on one-way messaging, often falls short because it overlooks the behavioral drivers shaping real decisions. Behavioral science strengthens SBCC by grounding it in how people think and act, enabling more community-centered design.

This shift is clear across Busara's research. In Nigeria's food safety study, behavioral diagnostics showed how trust signals, religious norms, and visual heuristics guided choices, explaining why generic hygiene messaging had limited impact and why co-created, visibility-enhancing cues worked better. Food diary studies across Asia and Africa revealed that affordability cues, identity, and cultural beliefs shape poultry consumption, highlighting the need for trusted, locally resonant narratives.

Effective SBCC must also be co-created and iterative, moving the field from top-down instruction to community-driven change. Insights from Busara's food waste studies in Kenya and Nigeria showed that rejection of imperfect produce stemmed from social norms and risk perceptions, requiring jointly designed vendor displays and consumer messaging. Farmer research in Ethiopia and India showed that agro-advisory uptake hinges on credible, usable guidance, strengthened by gamification showing that centering people's experiences drives safer, healthier, more resilient food systems.
