Natural hazards, internal migration and protests in Bangladesh

Does internal migration following natural hazards increase the likelihood of protests in migrant-receiving areas? To address the question, this study first looks at the extent to which experiencing different forms of natural hazards contributes to a household’s decision to leave their district of residence. In a second step, the article explores whether that internal migration flow increases the number of protest events in migrant-hosting districts. In doing so, it contributes to the existing debate on the extent to which natural hazards impact the likelihood of social contention, and the role of migration as a linking pathway in that relationship. The impact of climate-related shocks may erode household assets and therefore adaptive capacity in ways that can eventually influence decisions to migrate to larger urban centres. Although migrants are agents of economical and technological change, urban environments may impose challenges to recently arrived migrants and their host communities, affecting the motivations and mobilization resources of urban social groups to protest. As a consequence, the probability of urban unrest in these locations is expected to increase. To test this, I use geo-referenced household-level data from Bangladesh for the period 2010–15, which records households’ experiences of different forms of natural hazard and internal migration flows, available from the Bangladesh Integrated Household Survey. It combines this with data on protests, derived from the Armed Conflict Location and Event Data. Findings suggest that flood hazards in combination with loss of assets increase the likelihood of internal migration, but unlike other types of domestic mobility, hazard-related migration does not increase the frequency of protests in migrants’ districts of destination.
