ABSTRACT Monitoring urban heat islands (UHIs) is crucial as it has become a major health hazard. This paper focuses on an empirical study analyzing causes and spatiotemporal attributes in tropical metropolis to enrich the climate database. A comparative assessment of temperature patterns from Landsat Terra satellite sensors was performed for day–night scenarios summer winter. Results showed that 2003 2014, there sharp rise about 4 °C average daytime summer. The temporal UHI increased by 28.52% 8.37% winter last two decades. thermal hotspot development linked land cover dynamics using surface indices, use cover, local zone patterns. dense green reduced 652.69 km2, reflecting cause behind development. presence water content reduced, depicted drop maximum NDWI values 0.425 0.152. identified compact mid-rise building arrangements within built area critical creation. Green roofing with low plants should be prioritized at such locations since can reduce 2.6 °C. thorough analysis change will aid sustainable planning similar city regions.

Abstract Urbanization is accelerating rapidly, highlighting the critical role of aligning with sustainable development goals, urban green and blue spaces (UGS UBS). These play a crucial in enhancing health well-being city residents terms ecology. Acknowledging importance ecology, this study utilizes Sentinel-2A data support vector machine classification, aimed to identify UGS UBS. To examine connections between UBS, specific indices, spectral bands, textures were calculated. Additionally, concentration chlorophyll, vital indicator ecological health, was assessed using three indices. Structural equation modeling employed elucidate relationship UBS their impact on chlorophyll for years 2017 2023. In model, exhibited positive path coefficient (0.25) chlorophyll-a, indicating that an increase associated levels. Conversely, 2023, turned negative (− 0.83), presenting stark contrast model. This shift suggests potential environmental or changes, such as alterations quality type spaces, potentially including more non-native ornamental plants contribute less overall can be subjected pollution, soil compaction, other stressors reduce plant health. Similarly, showed its from − 0.99 1.8 suggesting improvements cleaner water planning strategies at reducing pollution. The consistent across both bodies are not contributing Chl levels due complex interactions surroundings. However, further research essential delve into these dynamics comprehend implications sustainability.

Impact of Changes in—Blue and Green Spaces on the Spatiotemporal Evolution of the Urban Heat Island Effect in Ningbo and Its Implications for Sustainable Development

Sustainability, Journal Year: 2025, Volume and Issue: 17(9), P. 4156 - 4156

Published: May 4, 2025

Blue and green spaces (BGS) play a crucial role in mitigating the urban heat island (UHI) effect by not only lowering land surface temperature (LST) but also regulating microclimate enhancing ecosystem services. In this study, Ningbo City is selected as research area. LST data for years 2014, 2017, 2020, 2023 were retrieved using Landsat 8 imagery processed via Google Earth Engine platform, employing an atmospheric correction approach. Simultaneously, use types classified random forest algorithm. Based on these datasets, Geographically Temporally Weighted Regression model was employed to quantitatively assess spatial temporal impacts of BGS changes UHI effect. The results reveal that (1) from 2014 2023, exhibited consistent decline, while construction expanded significantly, leading gradual increase annual average LST; (2) strong zones primarily concentrated urbanized closely aligned with regions elevated minimum, maximum, values blue significantly lower than those observed cultivated land; (3) variation influence coefficient space greater space, suggesting stronger spatiotemporal heterogeneity its regulatory thermal environment. Additionally, green-to-blue area ratio increased 9.7:1 12.8:1 deviating progressively optimal ecological balance. To promote sustainable development, it imperative strengthen conservation restoration BGS, optimize their configuration through evidence-based planning, ensure long-term stability functions.

Urbanization has significantly impacted the environment and urban life, with green spaces playing a crucial role in enhancing sustainability public health. Urban Green Spaces (UGS) offer benefits such as temperature regulation, ecological services, improved thermal comfort, while providing entertainment, culture, disaster avoidance, services. This study evaluates cooling effects of UGS mitigating Heat Islands (UHIs) phenomenon Delhi, India, using satellite imagery to assess Land Surface Temperature (LST) 24 parks. We calculated Park Cooling Intensity (PCI) by applying mono-window algorithm. found that parks larger than 1.55 hectares dense vegetation water bodies reduced surrounding temperatures up 8.28 °C. The PCI effect was influenced park size, density, presence bodies, denser demonstrating enhanced capacity. These findings highlight importance integrating into planning vital infrastructure for resilience, reducing heat-related health risks, ensuring equitable access benefits. also highlights addressing socio-economic disparities accessibility, which have significant implications development. emphasized formulating strategic approach focuses on spaces' growth, conservation, allocation, thereby fostering eco-friendly, habitable, robust environments.
