Examining the interconnected dynamics of urbanization and climate change is crucial due to their implications for environmental, social, public health systems. This study provides a comprehensive analysis these in Peshawar Valley, rapidly urbanizing region Khyber Pakhtunkhwa, Pakistan, over 30-year period (1990–2020). A novel methodological framework integrating remote sensing, GIS techniques, Google Earth Engine (GEE) was developed analyze land use/land cover (LULC) changes, particularly expansion built-up environment, along with surface temperature (LST) heat index (HI). intricately links elements, providing unique perspective on environmental transformations occurring Valley. Unlike previous studies that focused individual aspects, this research offers holistic understanding complex interplay between urbanization, use dynamics, variations. Over three decades, expanded significantly, areas increasing from 6.35% 14.13%. The population surged 5.3 million 12.6 million, coupled significant increases registered vehicles (from 0.171 1.364 million) operational industries 327 1155). These transitions influenced air quality as evidenced by highest mean LST 30.30 °C maximum HI 55.48 °C, marking notable increase 50.54 °C. changes show strong positive correlations areas, size, vehicles, industrial activity. findings highlight urgent need adaptive strategies, interventions, sustainable practices mitigate impacts Sustainable urban development strategies mitigation measures are ensuring livable resilient future region. long-term robust foundation projections policy recommendations.

Analysis of Morphological Impacts on Cooling Effects of Urban Water Bodies in Five Cities of Zhejiang

Water, Journal Year: 2024, Volume and Issue: 17(1), P. 80 - 80

Published: Dec. 31, 2024

Urban water bodies play a critical role in regulating urban climate, mitigating the heat island effect, and enhancing ecological environments. This study focuses on five typical cities Zhejiang Province, systematically analyzing cooling effects of bodies. Specifically, divides buffer zones into basic analytical units based road network performs land surface temperature inversion use classification using Google Earth Engine platform. Six representative morphology indicators are selected, contributions these to evaluated Gradient Boosting Decision Tree regression model. Additionally, optimization strategies for different proposed. The results show following: (1) Water central areas generally exhibit significant effects, with average reduction exceeding 5.13 °C compared built-up all cities. (2) is higher than that areas, difference at least 0.63 °C. (3) In Huzhou Jiaxing, high-temperature low-temperature relatively concentrated, while Jinhua, Quzhou, Shaoxing, more interspersed distribution observed, reflecting spatial heterogeneity. (4) Among body indicators, edge density, proportion landscape area occupied by patches, largest patch index water, shape exert larger impact effects. These findings provide scientific guidance optimizing layout improving thermal
