People love to connect with nature and that's possible with vertical gardens on high-rise developments. But gardens need a gardener to keep things under control.
The release of a roadmap for green roofs, walls and facades in Australia can help our cities catch up with the world leaders in urban greening.
Greater urban density is making it harder to preserve, let alone increase, tree cover. It's vital, then, to demonstrate the full value of green infrastructure for healthy liveable cities.
Research shows if Australia encourages greenery on buildings, it will reduce temperatures in the city, as well as potential for flash flooding. It also creates new habitats and socialising spaces.
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.
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?
