Food security programming in developing countries is often challenged by limited access to accurate and current data. This study describes a typology to help programmers identify food security priority areas and target interventions using limited data. The typology classifies interventions based on location and magnitude of nutrition constraints using four indicators: agricultural potential, availability, access, and utilization. This paper suggests that the methodology can be easily adapted to various types of interventions and developing-country contexts to support more focused food security interventions.
