A review of over 200 studies found that botanical gardens are the most effective green spaces for cooling surrounding city streets during heatwaves. The research found that botanical gardens, such as the Royal Botanic Gardens at Kew in London, reduced air temperatures during heatwaves by an average 5°C. Wetlands, green walls, street trees and even balconies with plants were found to significantly mitigate high temperatures. As the climate crisis causes temperatures to soar across the world, the authors of this research hope their results will inform policymakers involved in city planning.
