This paper examines the impact of refugee camp hosting on local communities, specifically the Rohingya crisis in Cox's Bazar, Bangladesh. It uses remote sensing measurements and panel data to compare areas and individuals at varying distances before and after the Rohingya arrived. The results highlight the complex dynamics of areas that host displaced populations. The paper finds that when the proximity of a grid to the refugee camps increases by 30 km (18.6 miles), night light density rises by 1.7 percent and deforestation expands by 0.02 percent. Land use results align with these findings, showing a decline in dense-open forest and an increase in land covered by grass and crops. The analysis of individual-level data suggests that the Rohingya's presence manifests in higher job formality, better access to aid, and more food consumption-all largely attributable to the activities of humanitarian organizations. However, their presence is also associated with heightened safety concerns and a higher prevalence of viral diseases such as diarrhea, fever, and cough.
