Climate change, the COVID-19 pandemic, and conflict drastically affected the food systems landscape worldwide. By the beginning of 2024, 1.3 million people in Burkina Faso, the Gaza Strip, Mali, Somalia, and South Sudan faced catastrophic food insecurity. The global community has seen calls to secure a sustainable and equitable food system. This includes calls for more research to make sure evidence on what works informs the programs and policies implemented. This evidence and gap map (E&GM) responds to this demand by systematically collating and regularly presenting updated evidence, in an organised and user-friendly manner.
In 2020, the International Initiative for Impact Evaluation (3ie) started this E&GM, commissioned by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). 3ie has periodically updated this living map with all available impact evaluations and systematic reviews in low- and middle-income countries on the effects of interventions on three food system domains: (1) the food supply chain, (2) the food environment, and (3) consumer behaviour. Over the past year, we added social protection interventions, gender-transformative interventions and outcomes, and an expanded version of women’s empowerment interventions to provide a more comprehensive map for researchers and practitioners.
