This study investigates the interplay between land use/land cover (LULC) changes and surface temperature (LST) dynamics in context of Rohingya refugee crisis Cox’s Bazar, Bangladesh, over period 2013–2024. The area comprises 34 camps characterized by rapid anthropogenic transformation evaluated using Landsat 8 imagery. Key LULC categories, including Built-up, Mixed Forest, Waterbodies, Barren Land, were analyzed supervised classification based on SVM methods multi-temporal indices like NDVI, NDWI, NDBI. Mono-Window Algorithm was employed to derive LST. Our results suggest an upward trend LST, particularly densely urbanized zones. Results also indicate a 97% decline forest 161.78% increase built-up areas 2013 2018, corresponding substantial rise Statistical analyses confirm strong correlations LST indices, with vegetation water bodies acting as natural cooling agents, while amplify thermal stress. highlights significant environmental impact settlements, emphasizing conversion forested urban spaces resulting findings underscore urgent need for sustainable use strategies, reforestation, planning mitigate increases degradation. This necessity coordinated international efforts repatriation reduce strain. These insights contribute growing body knowledge large-scale human displacement, providing basis policy development climate resilience vulnerable regions.

The rapid expansion of refugee settlements has caused significant environmental changes, particularly in regions experiencing forced displacement. Rohingya crisis Cox’s Bazar, Bangladesh, led to extensive deforestation and land transformation, affecting local climate conditions. While urbanization’s impact on surface temperature (LST) is well-documented, the consequences unplanned remain understudied. This study investigates cover changes LST dynamics from 2013 2024, offering a novel perspective refugee-induced changes. Using Landsat 8 imagery, four key categories (built-up, mixed forest, water bodies, barren land) were classified through Support Vector Machine (SVM) approach. temporal change these was examined. product (Band 10) Collection 2 Level (C2 L2) applied derive LST, while Normalized Difference Vegetation Index (NDVI), Water (NDWI), Built-up (NDBI) used assess vegetation urbanization trends. Findings reveal 97% decline forest 161.78% increase built-up areas between 2018, leading substantial increases. Statistical analyses confirm strong correlations multispectral indices, with bodies acting as cooling agents, urban amplify heat stress. underscores urgent need for sustainable management reforestation efforts mitigate degradation. It also highlights importance global cooperation balancing humanitarian needs sustainability, providing insights policymakers planners enhance resilience vulnerable regions.
