Cooling ranges for urban heat mitigation: continuous cooling effects along the edges of small greenspaces

How Can the Floor Area Types of a University Campus Mitigate the Increase of Urban Air Temperature?

“…For vegetated surfaces like lawns, the correct management is the reduction of annual mowings (Townsend-Small and Czimczik 2010; Gu et al 2015) that increase the photosynthetic total surface, thereby augmenting evapotranspiration and ground shading (Tan et al 2015;Mariani et al 2016). Shading properties of vegetation against the UHI effect have been demonstrated (Tan et al 2015(Tan et al , 2021Park et al 2022) and confirmed here in relation to taller vegetation. However, the fact that we recorded a higher ATMI for 4-mowing lawns than 3-mowing lawns is related to the difference of surface temperatures.…”

“…In urbanized environments, vegetation is one of the most studied surfaces that mitigates the UHI. Indeed, vegetation acts as a cooling island (CI) (Anniballe et al 2014;Cetin 2015;Marando et al 2019;Sebastiani et al 2021) due to its shading (Picot 2004;Mariani et al 2016) and the evapotranspiration from its surface, which reduce surface temperature (Mariani et al 2016;Park et al 2022). Moreover, the mitigation role of vegetation to climate change is twofold because it also inhibits the anthropogenic release of greenhouse gases while capturing and sequestering CO 2 (Shafique et al 2020).…”

“…Third, the 10 m distance between trees used to assess planting needs for creating tree-lined roads should be verified because in warm-temperate climate a cooling effect of tree cover was observed at distances up to 50% of the crown radius [38] .…”
