Recent research has found evidence for a linkage between conflict induced-displacement and violence. Yet, displacement is also caused by natural disasters, whose implications for security have until now not received much attention. Drawing on spatial data on flood-induced disasters and forced migration in Africa, we investigate the impact of migration caused by natural disasters on social conflict. We show that disaster-induced displacement differs from conflict-induced displacement and raises distinct security implications. We also consider if areas simultaneously affected by conflict and disaster-induced migration are particularly at risk of conflict. The results suggest that there is no such amplifying effect.

Recent scholarship has found evidence that refugee flows may inadvertently contribute to the spread of conflict across borders. Little is known, however, about the spatial diffusion of conflict within a state's borders and what role internal displacement plays in such a dynamic. This question is of relevance because of the particular marginalization of internally displaced persons, which make them at risk of predation and militarization by armed groups. Drawing on a novel global data set on internal displacement, we evaluate this question and find evidence for a similar mechanism leading to conflict spread operating at the domestic level.

Conflict, drought and locusts are leading concerns for African food security but the relative importance and spatiotemporal scale of crises resulting from each hazard is poorly characterized. Here we use continuous, subnational data to demonstrate that the rise of food insecurity across sub-Saharan Africa that began in 2014 is attributable to an increase in violent conflict, particu- larly in South Sudan and Nigeria. Although drought remains a leading trigger of food crises, the prevalence of drought-related crises did not increase from 2009 to 2018. When exposed to drought, pastoralists experienced more widespread, severe and long-lasting food crises than people living in agricultural zones. Food insecurity remained elevated in pastoral regions for 2 years following a drought, while agricultural regions returned to pre-drought food-security levels in ~12 months. The few con- firmed famines during the 2009–2018 period coincided with both conflict and drought, while locusts had little effect on food security during this period.
