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.

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.
Cairns has lots of hard grey infrastructure but much less green infrastructure that would reduce the impacts of the city’s growth. Karine Dupré

Cities can grow without wrecking reefs and oceans. Here’s how

Urbanisation is the main reason for rising temperatures and water pollution, but receives little attention in discussions about the health of water streams, reefs and oceans.
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.
A drain carries water but does little else, but imagine how different the neighbourhood would be if the drain could be transformed into a living stream. Zoe Myers

More than just drains: recreating living streams through the suburbs

Drains take up precious but inaccessible open space in our cities. Converting these to living streams running through the suburbs could make for healthier places in multiple ways.
The public and finance sectors – but not the government, it seems – are questioning the wisdom of investing in infrastructure for projects like the Adani coal mine. Lukas Coch/AAP

To get the ‘good debt’ tick, infrastructure needs to be fit for the future

If infrastructure is to meet the needs and challenges of an uncertain future, we need to move beyond the AAA ratings mindset and aim for net-positive social and ecological outcomes as well.
Whether it’s pressures of space or a warmer climate, which is affecting Melbourne’s elms, urban greening must respond to the challenges of 21st-century urban living. Joe Castro/AAP

Higher-density cities need greening to stay healthy and liveable

Greening cities that are becoming denser is a major challenge. City-dwellers' health benefits from both well-designed green spaces and urban density, so we must manage the tensions between them.
Upper Coomera is one of those fast-growing fringe suburbs that are hotter because of tightly packed housing with less greenery. Daryl Jones/www.ozaerial.com.au/

Out in the heat: why poorer suburbs are more at risk in warming cities

Recently published research has found that the concentration of poorer people in hotter places is a real problem for cities' capacity to cope with climate change.
