Flood-Induced Displacement and Civil Conflict

Large, catastrophic floods intensify environmental scarcity and can lead to mass displacement from affected areas. The sudden and mass influx of migrants could increase the risk of social tensions in receiving areas. In this paper, we analyze the impact of the displacement induced by large floods on civil conflict using historical data for 126 countries during 1985-2009. Our results suggest that while the displacement caused by large floods did not ignite new conflicts, it fueled existing conflicts. This effect was larger in developing countries and it receded with time, vanishing five years following the flood. (C) 2014 Elsevier Ltd. All rights reserved.
