WFP conducts food security analysis to identify food insecure populations and design appropriate assistance programs. This involves assessing who is vulnerable, where they live, why they are vulnerable, and how the situation may evolve. Analysis is based on household surveys, satellite data, and partnerships. It informs targeting of food aid, cash/voucher programs, and other interventions. WFP has 150 analysts worldwide who produce assessments, monitoring reports, and use tools like GIS to analyze vulnerabilities and map food insecurity.
