Not only do healthy, well-maintained trees provide shade and benefit the ecosystem, they can have a meaningful social impact: people in newly greened neighbourhoods start to look out for each other.
Green infrastructure can be delivered relatively easily using existing planning processes. The main obstacle could be psychological: planners are wary of disruption to embedded practices.
Achieving green cities will require more than just canopy cover targets and central city strategies. It will need new approaches to urban planning and development.
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?
