Perceived deservingness shapes attitudes toward environmental migrants in rural Bangladesh

Abstract As climate change intensifies, internal migration due to extreme climate events is becoming increasingly common in the Global South. Yet, little is known about how rural host communities respond to incoming environmental migrants. Here, we study attitudes toward environmentally displaced people in northern Bangladesh, focusing on perceived deservingness, empathy through shared experience, and exploratory proxy indicators of prior migrant exposure/contact. Using a pre-registered face-to-face survey of 265 rural residents, including a forced-choice conjoint experiment, we assess how migrant characteristics (reason for migration, occupation, religion, distance to origin) affect host community attitudes. We find that migrants displaced by riverbank erosion are more likely to be accepted than economic migrants (by 21%-points, p < 0.01) and face less discrimination based on other characteristics, indicating that deservingness strongly shapes attitudes. Regarding shared experience of erosion, which we propose as a proxy for empathy, models estimated a positive coefficient (13%-points, p = 0.122), hence not supporting, but indicative of a positive association between experiential proximity and greater acceptance of environmental migrants. We find no credible evidence for heterogeneity in migrant acceptance using coarse proxy measures of prior migrant exposure/contact. These results suggest that, even in resource-constrained regions, moral judgments play a central role, and that experiential proximity may be associated with more inclusive attitudes, informing policies for societal resilience under environmental stress.
