Greening cities have a huge impact. The trees go beyond just lowering temperatures. They help decrease the demand for indoor cooling like air-conditioners saving money.
Urban residents are increasingly keen to farm verges, parks, rooftops and backyards, but planning rules sometimes stand in the way.
It is possible to use small spaces such as transport corridors, verges and the edges of sporting grounds for native wildlife habitat restoration, helping to bring biodiversity back into cities.
It seems like a 'no brainer' to use urban greening to help cities adapt to increasing heat, but the uptake of green infrastructure, such as trees and vegetated roofs, surfaces and walls, is slow. Why?
