ABSTRACT The surface urban heat island (SUHI) effect presents a significant challenge in environments. However, there is spatiotemporal variability the SUHI and its drivers, which often overlooked. To address this issue, study employs geographically temporally weighted regression (GTWR) model to analyze heterogeneity of driving factors. findings reveal following: (1) SUHIs central area Wuhan are located mainly on both sides Yangtze Han Rivers, most notably Qingshan Industrial Zone; (2) city center, land temperature (LST) strongly positively correlated with bare soil index (BSI), normalized difference built‐up (NDBI), vegetation (NDVI), nighttime light (NTL); (3) clear temporal disparities exist between LST NDBI, NDWI, NTL factors displaying notable variations; (4) comprehensive analysis has yielded quantitative relationships associated drivers. In summary, it been proven that differences Therefore, impact should be considered when studying mitigation effect.

ABSTRACT In recent years, aquaculture has significantly expanded in tropical and subtropical developing countries. This expansion led to substantial economic, food security, environmental impacts. The southwestern region of the Ganges–Brahmaputra Basin faces severe waterlogging problems, largely because shrimp farming affects local livelihoods. study examines consequences land‐use changes polders Bangladesh by analysing 48 years Landsat imagery from 1972 2020. highlights a significant shift rice cultivation farming, leading more waterlogged areas fewer settlements poor drainage, freshwater scarcity, increased salinity. We developed drainage model for via MIKE11 software assess area's capacity found that current systems are insufficient, especially monsoon drainage. inadequacy encouraged toward farming. Our research aims shed light on economic challenges area, promoting sustainable management water resources. detailed insights this provide framework develop practical united strategies address issues minimize their varied impacts people economy region.
