The document summarizes research on the impact of refugees on host communities' food security. While initially refugees and host communities face food security problems, over time markets adapt through labor and goods exchanges. Refugees may increase food production and prices in host areas. More evidence is needed on long-term impacts and how policies can strengthen host resilience, including public goods, infrastructure, and aligning incentives across stakeholders to solve protracted crises. The research agenda should analyze relative impacts of policy options to transition from aid to development.
