“…While our empirical study results have demonstrated a high level of robustness, it is important to acknowledge that the impacts of GS coverage and its spatial distribution on LST may vary in other cities with distinct climate backgrounds. For example, variations in tree/grassland fraction influenced by different background climates may impact the cooling effect of GS . Thus, further research is needed to assess how these impacts may change under different climate conditions.…”

Enhancing the cooling effectiveness of green spaces (GSs) is crucial for improving urban thermal environments in the context of global warming. Increasing GS coverage and optimizing its spatial distribution individually proved to be effective urban cooling measures. However, their comparative cooling effectiveness and potential interaction remain unclear. Here, using the moving window approach and random forest algorithm, we established a robust model (R 2 = 0.89 ± 0.01) to explore the relationship between GS and land surface temperature (LST) in the Chinese megacity of Guangzhou. Subsequently, the response of LST to varying GS coverage and its spatial distribution was simulated, both individually and in combination. The results indicate that GS with higher coverage and more equitable spatial distribution is conducive to urban heat mitigation. Increasing GS coverage was found to lower the city's average LST by up to 4.73 °C, while optimizing GS spatial distribution led to a decrease of 1.06 °C. Meanwhile, a synergistic cooling effect was observed when combining both measures, resulting in additional cooling benefits (0.034−0.341 °C). These findings provide valuable insights into the cooling potential of GS and crucial guidance for urban green planning aimed at heat mitigation in cities.

This research provides a brief insight into the spatial nature of urban sprawl in functional urban areas (FUAs) of European capitals, as opposed to most investigations into urban growth that focus on case studies. Its purpose is to identify European capitals that grow the most and characterize the spatial aspect of urban sprawl and dynamics of ensuing land‐cover change between 2006, 2012, and 2018. We employed open data from the Urban Atlas, which we processed with spatial analyses and the NUASI (Normalized Urban Atlas Sprawl Indicator) to quantify the scale of urban sprawl in the investigated areas. The results demonstrate the most dynamic growth for Central and Eastern European and Iberian Peninsula capitals, while it seems to be slowing down in other Western European and Balkan countries. Moreover, we found out that FUAs of European capitals differ in terms of the scale and pace of uncontrolled urban sprawl. The results of our comparative analyses are relevant to urban development because they can identify areas exhibiting various scales and paces of urban sprawl to take targeted actions depending on the needs defined by decision‐makers and strategies.
