All parks are not equal. The response to the opening of golf courses to the public during the COVID pandemic shows the quality of green open space is a big issue for city residents.
In South African cities there's an uneven distribution of trees, greenery and parks across racial and income geographies.
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.
Half-a-dozen strategies are effective for cooling urban areas. Used in combination, these strategies can drop the temperature even more.
Sleep might be a key factor in the link between greener neighbourhoods and better health. A new study shows living in an area with more tree canopy improves people's odds of getting enough sleep.
At the peak of a summer heatwave in Adelaide, an aerial survey of land surface temperatures reveals just how much cooler neighbourhoods with good tree and vegetation cover can be.
Residents of the 'leafy suburbs' will continue to fear what they might lose to increasing urban density without an explicit planning approach that enhances green space in affected neighbourhoods.
When so much of the green space in our cities is in the form of nature strips, current restrictions on plantings are denying us the many social and environmental benefits of more diverse greenery.
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.
The research has been done. The evidence is in. We know how to create cities that are sustainable, liveable and affordable. But we have yet to apply that knowledge widely across Australian cities.
Cities around Australia have plans to increase their green space, but new research shows not all green spaces are equal. Good tree cover is better than grassed areas for residents' mental health.
Thirty tree species make up more than half of Australia's urban forests. Some won't survive climate change, so cities must plant a more diverse mix of the right species to preserve their tree cover.
Not all of the solutions to the climate and ecological crisis have to be painful.
Two trends in Australia, an ageing population and warming climate, are increasing the threat that heatwaves pose to our health. Increasing vegetation cover is one way every city can reduce the risk.
Koalas can cope with the stresses of city life provided we plan urban developments in ways that help meet their basic needs.
Barangaroo is an example of a development with admirable green credentials, but it is also an exclusive precinct that has played a role in displacing the disadvantaged from this part of Sydney.
Australian cities are home to many threatened species but are also where biodiversity is being destroyed by development. But what if planning and design processes built nature into the urban fabric?
Darwin's climate is getting even hotter and it's one of the main reasons people leave the city. A lot more can be done, though, to make our tropical cities safe, cool and enjoyable.
If the nature we desire is, in fact, its expression as untamed wildness, then we should turn to the creativity of artists as well as urban designers when building our cities.
Residents often have concerns about informal green space but some still use it. Work to enhance these areas should aim to resolve these concerns without destroying what residents do value.
