People on moderate incomes, including police and emergency workers, have been forced to seek housing on the city fringes, far from their places of work. But there are ways to reverse this trend.
Cities all over the world are facing growing challenges to provide clean, reliable water. And many of the fixes, such as desalination plants, have a huge carbon footprint.
King tides and rising seas are an increasing and predictable threat, but adaptation plans to limit the damage to coastal property are still not managing the political obstacles.
One potential benefit of WestConnex, which remains untouched, is that it could relieve Sydney's city centre from cars and make it more pedestrian-friendly.
Groundwater is out of sight, but it shouldn't be out of mind. As cities struggle to cope with drought, we should remember that our largest stocks of water are hidden deep underground.
New York soon may charge a fee to drive into central Manhattan as a way of reducing traffic and raising funds for public transit. An urban scholar says this step is overdue in the United States.
For a public space to be seen as safe, welcoming and accessible, a diverse range of people need to actively use it. That's why any space-changing project needs to engage broadly with the community.
The situation in Perth in particular has some parallels to that of Cape Town, but Australian cities responded to the last big drought by investing in much bigger water supply and storage capacity.

Google's proposals for a high-tech development on Toronto's lakefront is a radical departure from the principles that have guided city planning in Canada for decades.
