Flooding is a common experience in monsoonal regions of Southeast Asia, where diverse flood regimes have for centuries shaped agrarian and fisheries-based livelihoods. However, in recent public discourse, the link between flooding and migration is most often made with regard to catastrophic flood events. News images of frequent and intense weather-related flood events in the region’s low-lying megacity and delta regions in recent years has contributed to a perceived link between extreme environmental events and mass migration through displacement. Yet, this focus on mass displacement frames migration in largely negative terms. Mobility is seen as a failure of adaptation to a changing environment, with both trans-border and internal population mobility to some even regarded as a security issue.
