The lure of suburbia clearly remains strong. To deal with sprawl, planners need to increase urban density in a way that resonates with the leafy green qualities of suburbia that residents value. Julian Bolleter

GOD save us: greenspace-oriented development could make higher density attractive

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.
Allowing residents to remove trees within three metres of buildings or ‘ancillary structures’ could dramatically alter the green infrastructure of dense inner Sydney suburbs like Rozelle. Tom Casey/Shutterstock

Trees can add $50,000 value to a Sydney house, so you might want to put down that chainsaw

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.
Increasing heat in Sydney and other Australian cities highlights the urgent need to apply our knowledge of how to create liveable low-carbon cities. Taras Vyshnya/Shutterstock

We have the blueprint for liveable, low-carbon cities. We just need to use it

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.
Imagine Hyde Park in Sydney without its tree cover … the impact on this space and the many people who spend time in it would be profound. EA Given/Shutterstock

Increasing tree cover may be like a ‘superfood’ for community mental health

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.

Our cities need more trees, but some commonly planted ones won’t survive climate change

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.

How do we save ageing Australians from the heat? Greening our cities is a good start

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.
Barangaroo is a development on Sydney Harbour with strong green credentials, but it’s overwhelmingly the well-off who enjoy the benefits. Brendan Esposito/AAP

Making developments green doesn’t help with inequality

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.
An impression of biodiversity sensitive urban design (BSUD) developed by the authors in collaboration with Mauro Baracco, Jonathan Ware and Catherine Horwill of RMIT’s School of Architecture and Design.

Here’s how to design cities where people and nature can both flourish

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?
Stony Creek drain: untidy and often slightly threatening, informal green space still has value for residents, which appropriate intervention can enhance.

How do we turn a drain into valued green space? First, ask the residents

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.
