Many new housing developments are being built along busy roads and rail lines, but lack design features that would reduce occupants' exposure to harmful traffic pollution.
Urban residents are increasingly keen to farm verges, parks, rooftops and backyards, but planning rules sometimes stand in the way.
The rail project may well help get more commuters into the CBD, but offers few benefits for the parts of the broader metro area where most population growth is occurring.
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.
Yangon's traffic woes are set to last.
There are very few approaches that examine all aspects of the complexity of urban design and development. Ergonomics, human factors and sociotechnical systems methods offer a way forward.
Urban planners have been blamed for a lot of things, including higher housing costs. But the solution is to refine the process, not sideline the good planning that makes cities safe and liveable.
Conflicts over coastal areas have largely been between development and preserving what makes these attractive places to live. Rising sea levels are now complicating our relationship with the coast.
One reason Perth's Roe 8 project is the subject of passionate protests is that it's a case of a government asserting power over people rather than exercising power with local communities.
One year on, the Turnbull government is touting the economic benefits of an infrastructure agenda that neglects the other important functions of transport projects.
Exceptional projects can emerge when regulations are sensibly relaxed due to context. A Fremantle project is a model of progressive higher-density possibilities resulting from flexible planning rules.
A project in the Western Himalaya has highlighted some valuable lessons for the future.
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.
Big ideas and big dollars have been invested in making 'memorable' places. Paradoxically, as similar solutions are adapted in diverse settings worldwide, this can lead to an uneasy new placelessness.
The rise in temporary use of urban space requires a looser planning vision that can draw on this new type of city-making to inform longer-term developments.
If the sharing economy is here to stay, planners and designers must respond with imagination to spread the positive effects of the tourism economy for the benefit of residents as well as tourists.
If Perth can preserve the rich biodiversity of its setting, it will become a model for sustainable city development that fully connects with the value of natural ecosystem services.
The system of apartheid is long gone. But its legacy of poor funding for historically black universities - and of planning that banished black universities to cities' margins - remains.
With foresight, we can steer our cities closer to the future we want instead of the futures we fear.
Cities are home to many different people who will not always agree. We need to learn to embrace public debate as an ongoing, constructive process for working through diverse views and values.
