With an ever-increasing cost to extract dwindling raw materials, it's time to look at cities as urban mines. We're developing the tools to do that.
A suburb in the Irish city of Cork sets the standard for involving the community in heritage building conservation. Public engagement is the key to managing the inevitable conflicts.
Adaptively re-using buildings can preserve heritage while enabling new uses that help make cities more liveable and sustainable.

The State of Australian Cities Conference begins in Adelaide today. In major cities across the nation, there's a stark contrast between lofty planning goals and the sprawling reality on the ground.
Traffic congestion is the main cost that cars create when they use existing roads. Road use charges are a more efficient and fairer way to cover the cost and help ensure traffic flows.

Low-density suburbs can cause social isolation that's harmful for individual and community well-being. But research confirms we can plan neighbourhood centres so they become vibrant social hubs.
What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
The secret of creating attractive, liveable places sounds deceptively simple: connect people to places, people to transport and people to people.

Movies often portray the city as a dystopia, particularly in the 'neo-noir' genre, which explores postmodern themes. TV shows and ads present an altogether sunnier picture of life in the city.
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.
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.
Faecal transplants and virtual nature are technological solutions to ‘nature deficit disorder’ from urban living. Such 'quick fixes' offer some benefits, but are no substitute for the real thing.
Urban festivals built on community involvement can reinvigorate places and create a shared sense of place and purpose that lasts long after the event is over.
