TL;DR: The cooling effect of blue-green space has been recognized as a promising approach to mitigate the urban heat island (UHI), while the quantitative role (threshold-size for cooling) is still uncertain this article.

TL;DR: In this article, the authors defined the urban cooling island (UCI) extent, intensity, and efficiency, as well as the threshold value of efficiency (TVoE) introduced from the law of diminishing marginal utility for the first time.

TL;DR: In this paper, the authors used spatial/statistical methods to assess the cooling effect of blue-green spaces in different seasons and found that the area and cooling extent and intensity conform a logarithm function with significant correlations except for winter.

TL;DR: It is found increasing (artificial) rainfall and irrigation contribute to improving the cooling intensity of grassland in both climates, particularly in the hot-dry environment, and the area of trees in both climate zones’ cities should generally be planned around 0.5 ha.

TL;DR: In this paper, the authors developed and applied a multi-dimensional vulnerability assessment framework for understanding the impacts of climate change-induced hazards in Sub-Saharan African cities, including urban flooding.
