The increasing trend in land surface temperature (LST) and the formation of urban heat islands (UHIs) has emerged as a persistent challenge for planners decision-makers. current research was carried out to study use cover (LULC) changes associated LST patterns planned city (Kabul) unplanned (Jalalabad), Afghanistan, using Support Vector Machine (SVM) Landsat data from 1998 2018. Future LULC were predicted 2028 2038 Cellular Automata-Markov (CA-Markov) Artificial Neural Network (ANN) models. results clearly emphasize different between Kabul Jalalabad. Between 2018, built-up areas Jalalabad increased by 16% 30%, respectively, while bare soil vegetation decreased 15% 1% 4% 30% showed highest seasonal annual LST, followed vegetation. maximum occurred during summer both cities predictions that (48% 55% 2018) will increase approximately 59% 68% 79% Jalalabad, respectively. Similarly, simulations percentage with higher (> 35°C) would (0% 5% 22% 43% 2038, Kabul's shows lower than Jalalabad's city, primarily due urbanization greater center.

Urban heat island analysis based on high resolution measurement data: A case study in Beijing

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 106, P. 105389 - 105389

Published: March 28, 2024

Urban heat island (UHI) is a widely concerned urban climate which impacts billions of residents worldwide. Nevertheless, inadequate rigorous air temperature (Tair) measurement has become an obstacle to UHI research and mitigation, especially in megacities like Beijing. In this study, we applied 1-km hourly Tair dataset interpolated from records 521 stations The enables us analyze patterns on block scale the landscapes combined with local zones (LCZ) scheme. Our results indicate that: (1) its temporal variation each LCZ vary significantly, are highly relevant their morphology thermal-radiative properties. (2) 1 2 have highest nocturnal intensities (UHII). Discrepancies among LCZs also cause various variations UHII. (3) spatial pattern affects regional temperature. Area ratio aggregation extent 1&2 show significant positive correlations temperature, while A&D&G opposite regularity. (4) Distinct mitigation strategies put forward for subarea Beijing endowments population structure. study provides insight into plausible advice

Progress on green infrastructure for urban cooling: Evaluating techniques, design strategies, and benefits

Urban Climate, Journal Year: 2024, Volume and Issue: 56, P. 102077 - 102077

Published: July 1, 2024

Green infrastructure (GI) can act as an effective cooling strategy to mitigate the urban heat island effect. The complex interdependencies in built environment make it challenging quantify GI accurately. Present literature on often lacks focus techniques and overlooks co-benefits. This review addresses this gap by consolidating recent research standard design approaches maximize cooling. temperature results from are segregated type, technique local climate zones, scale. ENVI-met Weather Research Forecasting model (WRF) most common numerical modeling methods utilized for microscale mesoscale. Results indicate that highest air reduction is achieved arid climates, followed temperate, tropical, continental respectively. study suggests integrate into successfully, researchers should consider influencing factors like spatial distribution, microclimate, plant selection. Climate change intensifies severity of overheating; therefore, integrating cities must be done holistically co-benefits related trade-offs.

Are grand tree planting initiatives meeting expectations in mitigating urban overheating during heat waves?

Sustainable Cities and Society, Journal Year: 2024, Volume and Issue: 113, P. 105671 - 105671

Published: July 15, 2024

Numerous cities undertakes substantial tree planting initiatives for heatwave mitigation, driven by model predictions indicating a positive mitigation impact. However, emerging studies suggest that the transpiration behavior of trees during heatwaves significantly deviates from normal. This divergence, overlooked in current climate models, introduces possibility inaccuracies predicting cooling heatwaves. In this research, 1) The universality changed heat wave is revealed: study over 700 various species indicates at least 65 % sampled overestimated conventional waves. 2) scheme within revised to represent new pattern. Comparison shows overestimates peak hour efficiency 60 %. Consequently, effectiveness large-scale tree-planting as strategy may not meet expectations, emphasizing need refinement
