Heating Up the Dry Debate
The study evaluates the relationship between three drought indicators and communal conflict in Sub-Saharan Africa (1989-2014) using multilevel logistic regression. It finds that while all three measures are positively associated with conflict, the strength of the relationship increases as the measure moves from meteorological (SPEI) to agricultural (NDVI) and finally to socio-economic (EM-DAT) impacts. Specifically, socio-economic droughts approximately double the odds of experiencing violent conflict. However, the author notes that the NDVI effect may be driven by spatial correlation—where conflicts and vegetation loss occur in the same land types—rather than a direct temporal causal link. The study concludes that preventing meteorological droughts from escalating into socio-economic disasters could potentially reduce communal conflict risks.
