Environmental Change and Migration Aspirations: Evidence from Bangladesh

Abstract

The argument that environmental change is an important driving force of migration has experienced a strong revival in the climate change context. We examine whether and how different environmental stressors aspire people to move. The analysis relies on newly collected, cross-sectional survey data of 1594 households residing in 36 villages along the 250 kilometers of the Jamuna River in Bangladesh – an area affected primarily by floods and riverbank erosion. The results show that long-term environmental events, i.e., riverbank erosion, increase aspirations for internal, permanent migration, while short-term environmental events, i.e., floods, do not affect migration aspirations. These results suggest that depending on the type of environmental change, people might prefer migrating rather than staying put and thus, they entail important policy implications regarding the effects of climate change on future internal migration flows.
