Rising temperatures, a major global environmental challenge, negatively impact health, the environment, society, and economy. Surface Urban Heat Islands (SUHI), exacerbated by urbanization climate change, intensify vulnerabilities for urban areas residents. planning design aime to reduce these through large-scale small-scale interventions. However, addressing significance of capillary effects resulting from interventions bottom-up community engagement is important. acupuncture (UA) an emerging approach in contemporary that focuses on mitigate SUHIs at level. This study develops framework mitigating impacts UA implementation design. The proposed consists two key phases: diagnosis prescription. During phase, we analyzed heat-vulnerable points identify indicators contributing development exacerbation SUHIs. Then, employed Matrix Cross Impact Multiplications Applied Classification (MICMAC) technique comprehensively assess 75 influential related structure across various aspects scales, focusing mesoscale. Among them, 30 leading were identified, which morphological emerged as significant catalysts. Moving prescription developed UA-based called “5 Wh Question” addresses five fundamental questions: why, who, what, how, where. Our findings can provide comprehensive solutions policymakers planners address identified points.

Urban environmental quality consisting of ecological, physical, and socio-economic components, often deteriorates due to rapid urbanization. Therefore, using Remote sensing GIS environment, a composite measure is applied quantify the spatial heterogeneity urban for Class-1 Indian city (Siliguri). In this study, Environmental Quality Index was constructed 15 indicators three interconnected dimensions (eco-environment, landscape built-up, socio-economy). The domains were computed utilizing Principal Component Analysis with average aggregation techniques. Exploratory Spatial Data includes Moran's I Local indicator auto-correlation, used leverage information clusters, heterogeneity, outliers based on Index. results show that Siliguri's northern, north-western, southern parts experience good quality. effectiveness employed model checked R2 (0.832), providing fit model. Moreover, pattern (except socio-economy) revealed Low-Low values predominantly clustered in centre, while High-High patterns are concentrated towards periphery. Also, value indicated existence autocorrelation non-randomness Siliguri City. obtained from analysis indicate differentiation across study area. study's outcome relevant planning, frequent monitoring quality, governance, well-being inhabitants sustainable space.

The escalation of greenhouse gas emissions has led to a continuous rise in land surface temperature (LST). Studies have highlighted the substantial influence urban morphology on LST; however, impact different dimensional indicators and their gradient effects remain unexplored. Selecting area Shenyang as case, we chose various representing dimensions. By employing XGBoost for regression analysis, aimed explore 2D 3D seasonal LST its effect. following results were obtained: (1) spatial pattern spring winter was higher suburbs than center. (2) correlation patterns similar, except proportion woodland grass (PWG), digital elevation model (DEM), sky view factor (SVF), which exhibited opposing trends summer autumn. (3) Vegetation construction had highest index, followed by building forms natural landscapes morphology. (4) each indicator varied significantly across gradients. Among all indicators, landscape social development, forms, skyscape impacts areas. built-up areas greater suburban findings this study can assist adjusting provide valuable recommendations targeted improvements thermal environments, thereby contributing sustainable development.

The changes of land use/land cover (LULC) are important factor affecting the intensity urban heat island (UHI) effect. Based on Landsat image data Wuhan, this paper uses cellular automata (CA) and artificial neural network (ANN) to predict future in LULC LST. results show that built-up area Wuhan has expanded, reaching 511.51 545.28 km2, while vegetation, water bodies bare will decrease varying degrees 2030 2040. If continues expand rapidly, proportion 30~35 °C rise 52.925% 55.219%, affected with temperature >35 15.264 33.612 respectively. direction expansion range LST is obviously similar area. In order control alleviate UHI, rapid impervious layers (built-up areas) should be avoided greatest extent, city’s “green development” strategy implemented.

The inconstant climate change and rapid urbanization substantially disturb the global thermal balance induce severe urban heat island (UHI) effect, adversely impacting human development health. Existing literature has revealed UHI characteristics driving factors at an scale, but interactions between main of a grid scale assessment on context zones remain unclear. Therefore, based multidimensional climatic socio-economic statistical datasets, multi-time surface intensity (SUHI) was investigated in this study to analyze how natural-anthropogenic drivers affect variance SUHI vary their importance for changes other interaction factors. results show that mean value summer is higher than winter, daytime nighttime seasonal daily scale. SUHIs different have significant differences. When analyzing drivers' contributions with LightGBM model SHAP algorithm, we know monthly precipitation (PREC), estimated population (POP) pressure (PRES) are three major SUHI. mainly PREC, POP anthropogenic emission (AHE), influence rules natural driversare mostly opposite daytime. This highlights fundamental role background designing strategies. Irrigation or artificial rainfall will be effective mitigate low areas, while it more reduce AHE high areas. In where greening can difficult most developed cities, reducing AHE, increasing per capita GDP controlling may also contribute alleviating provides ideas developing responsive mitigation policies realistic setting.
