Abstract Rapid urbanization in developing countries has significant implications for local climate and environmental conditions. This study examines land use/land cover (LULC) changes their impact on surface temperature (LST) Patna, India from 1988 to 2022 using Landsat imagery geospatial techniques. cities can significantly alter climate, but the dynamics Patna were not well understood. Using supervised classification thermal band analysis, research quantified LULC transformations LST over 34 years. Results show dramatic urban expansion, with built-up area increasing 38 % 80 of total area, while vegetation decreased 44 just 7 %. These corresponded an overall increase LST, maximum temperatures rising by 1.06°C minimum 6°C. Strong correlations found between spectral indices like NDVI (negative) NDBI (positive). The reveals accelerated growth increases, especially after 2005, highlighting need sustainable planning strategies mitigate heat island effects improve comfort Patna. provides valuable baseline data understanding impacts rapidly growing Indian cities.

Air pollution (PE) and carbon emissions (CE) are obstacles to achieving the Sustainable Development Goals (SDGs) globally. The development intensity spatial form of urban blocks could affect PE-CE. relationship between these factors PE-CE was investigated in this study. results showed that: (1) distribution various that PE consistent with normalized difference vegetation index (NDVI), average height (AH) building density (BD), while CE BD, floor area ratio (FAR) otherness (BO). Neighbourhoods high NDVI have low CE. (2) Correlation analysis shows general, FAR, BO were positively correlated, negatively correlated. correlation other different functional has its own characteristics. (3) For interpretation random forest model, FAR a strong all areas. CE, 50% public blocks, 19% residential 28% industrial blocks. PE, 29%. (4) AH most frequently judged as important factors. key affecting AH. Public block (AREA). Industrial AREA, BD BO.

Urbanization is a major driver of land-use change, with significant implications for sustainable development in rapidly growing cities. In this study, we assess the spatiotemporal patterns urban expansion Lucknow, India, from 1991 to 2021, using geospatial techniques and Landsat satellite imagery. The key objective analyze growth patterns, identify contributing factors, evaluate sustainability these trends. Results reveal nearly fivefold increase built-up area, 53.86 km2 261.45 2021. Edge accounted 55.99% total 2001, while ribbon increased 18.06% 21.03% by Leapfrog development, considered unsustainable, rose 12.35% 17.35% Compared previous studies, findings highlight influence transportation infrastructure industrialization on sprawl, particularly northeastern northwestern zones. This study contributes offering zone-wise analysis which provides deeper insights into dynamics expansion. are crucial planners, as they suggest need more stringent zoning regulations targeted investments manage future sustainably minimising environmental impact.
