Determinants of resilience for food and nutrition security in South Sudan

The paper analyzes the determinants of long-term individual and community resilience for food and nutrition security in South Sudan using data from multiple sources including key informant interviews, household and community surveys, and georeferenced secondary data on climate, agricultural production, irrigation, and market access. Major agricultural development constraints as well as incidence of and responses to shocks and conflict are described. Climate-crop modeling and simulation methods are used to evaluate the constraints and to identify crop investment options. Then, a spatial typology of food and nutrition security is used to evaluate the constraints along the production-to-nutrition pathway to identify interventions that target different segments of the chain and options for improving agriculture and broader development outcomes. These are classified into production, access, and utilization efficiencies, and whether the underlying constraints are structural (i.e., level of efficiency remains the same over time) or stochastic (i.e., level of efficiency changes over time). The analysis is focused on about a dozen selected counties.
