Cities occupy just 3% of the Earth's surface, yet more than half the world's population live in urban environments. We need nation-wide plans to keep our cities cool so no one gets left behind.
Slashing carbon emissions by 68% by 2030 will depend on using the UK's infrastructure strategy effectively.
The states are primarily responsible for providing infrastructure, but lack the budgets, especially since the pandemic hit revenues. Making up the shortfall depends very much on the Commonwealth.
In an era of climate change and extreme weather, a microgrid — a self-sufficient, energy-generating distribution and control system — puts communities on the path to self-reliance.
Municipalities are now forced to identify new cemetery planning methods and models that are environmentally sensitive and consistent with diverse cultural practices, and facilitate social cohesion.
In South African cities there's an uneven distribution of trees, greenery and parks across racial and income geographies.
Natural assets produce important city services and complement engineered infrastructure. Investing in natural assets can help protect our environment, reduce municipal service costs and create jobs.
The coronavirus pandemic has highlighted the lack of green space available to those living in urban areas. Cities must be managed as ecosystems to make them more liveable and resilient.
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.
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.
From happier and healthier residents to more resilient buildings – green roofs offer significant benefits to cities.
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 values of a national park, translated to an urban context, to make life better for local people.
Expanding green cities needs a holistic approach, and learning from Melbourne and Canberra is a good place to start.
As the population of the world’s cities grows, so too does resource and energy use as well as waste generation. We can combat these issues with a circular economy that uses nature as a template.
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.
There are other things which cause air pollution – cars, for example – which will have a much bigger impact.
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.
Private finance crashed the economy and is too consumed by the profit motive to be a reliable ally against climate change. We should not allow COP24 to be their board meeting.
