People living in contexts prone to or affected by conflict suffer from many forms of deprivation. The international community plays a crucial role in strengthening the wellbeing of affected populations, including their food security. Unfortunately, quite often people exposed to conflict are not reached by national or international assistance because of targeting, accessibility, and marginalization. This can ultimately translate into a further deterioration of their food security status. This paper combines a geo-referenced household dataset collected in South Sudan in 2017 with the Armed Conflict Location and Events Data (ACLED), including information on conflict events. The collection of a very detailed household questionnaire in areas extensively affected by violence allows the analysis in a country generally underexplored by the empirical literature. The authors analyze the variation in conflict exposure across different households that live in the same district and test the link between conflict exposure and humanitarian assistance. They find that those who live in the higher-intensity conflict areas received less assistance than those less exposed to the conflict. The association is stronger within kind provision of inputs for agriculture and livestock rather than for direct food assistance. They suggest the presence of social elites and marginalization as a possible explanation. They discuss the advantages of using cash transfers through mobile phones to normatively decide beneficiaries; evidence also supports interventions combining input distribution and markets’ rehabilitation. More evidence is needed on the modalities of delivery of humanitarian assistance in different food crisis contexts.
