Botanical Gardens Lead in Urban Cooling During Heatwaves

Study reveals green spaces' pivotal role in combating urban heat, urging tailored solutions for communities.

Botanical gardens can cool city air by up to 5°C during heatwaves, outperforming other green spaces.
Wetlands, rain gardens, and parks also significantly contribute to urban cooling, with varying degrees of effectiveness.
The study emphasizes the importance of local factors in determining the success of green spaces in cooling cities.
Connecting green spaces into 'green corridors' can enhance their cooling effects and provide additional benefits such as carbon emission reduction and flood prevention.
The research highlights the need for more targeted studies to develop tailored cooling solutions for different communities.
