The demands on land and resources from our fast-growing cities are unsustainable, as are the wastes they produce. Yet still our leaders act as if unlimited growth is possible.
Other countries are planning new cities using technological innovation to achieve more sustainable development. Such plans aren't new for Australia, but existing city growth is the focus of attention.
Pacific island nations are often framed as remote atolls facing rising seas and cyclones. But their cities are growing fast, so are efforts to help the most climate-vulnerable people hitting the mark?
The focus on roads reflects the fact that this infrastructure program lags well behind the growth of our biggest cities, resulting in less-than-ideal transport patterns.
Population growth has pros and cons, and the Morrison government's plan is less about a change in immigration numbers than about increasing the benefits and minimising the costs.
Capital city populations are growing twice as fast as the rest of Australia, because of the employment and business opportunities and lifestyle on offer to both new migrants and long-term residents.
City fringe foodbowls supply much of our fresh produce and can increase climate resilience by making better use of wastewater and organic waste. A new roadmap outlines how to protect these foodbowls.
The Canadian immigration model shows that giving states and territories a say in immigration policy can help take the pressure off major urban areas.
Urban growth has had much less impact on commuting distances and times than media reports would suggest. The explanations include jobs being widely dispersed and residents' adaptable decision-making.

Ruth and Maurie Crow were early advocates of the compact city. They also warned 50 years ago that a clear justice intent was needed to shape cities for their citizens rather than vested interests.
Australian cities have turned to some very costly solutions when water is scarce. But as the world's second-highest users of water per person, more efficient use and recycling are key.
A new project documents who uses urban industrial lands slated for redevelopment. It reveals a vibrant but largely hidden sector at the interface between creative industries and small manufacturing.
Tokyo has experienced extraordinary population growth but is among the world's most liveable cities. Just how has it managed the pressures of growth?
Financial benefits are behind the development industry’s push for a continuous rapid population growth. But our poorly planned cities are ill-prepared and already struggling.
Australia has few places to capture the spill-over of talented workers priced out of the big cities. Some may leave the country altogether – and where talent goes, capital flows.
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.
Smart cities are usually optimised like a business for speed and efficiency. Placemaking can slow down cities to improve health and wellbeing and promote more democratic engagement of citizens.
