Periods of low rainfall or flooding also contribute to social instability and upheaval across Africa . The link between rainfall and conflict appears likely due to crop losses and declines in economic opportunity. One study found that dry growing seasons increase conflict incidence across 36 African nations, with spillover effects from the location of climate shock to neighbouring communities . Conflict-inducing impacts of drought have also been uncovered in Somalia , Uganda, Sudan, Ethiopia and Kenya , the DRC  and in a pooled sample of African and Asian countries . Extremely high rainfall may also incite conflict risk, although results are mixed . This uncertainty, combined with large uncertainties in rainfall projections under climate change, render future impacts of human-caused greenhouse gas emissions on rainfall-induced conflict in Africa highly uncertain.
