Cities – Analysis and Comment

The familiar images of high-rise development, looking north here from Surfers Paradise, tell only one part of the story of the Gold Coast. Andrew Leach

Looking past the Gold Coast the world sees today

Behind the built-up glitz of Surfers Paradise lies a deep history that has been written and overwritten in successive layers that have become thinner and thinner as time goes on.

Voices of residents missing in a time of crisis for public housing

The problem with most public housing ‘renewal’ programs is that the residents have the least say in what happens to the places they call home. The evidence of housing research is also being ignored.
‘Soft fall’ surfaces are widely used in play areas where children might fall, but can also get very hot in the sun, which undermines this safety benefit. Brisbane City Council/Flickr

Materials that make heat worse for our kids demand a rethink by designers

Commonly used surfaces in play areas, such as “soft fall” materials and Astroturf, can heat up to 80-100°C in the sun. This makes them a hazardous design choice, especially as the climate gets hotter.
Overflowing bins are one way to spoil the amenity of public space, but sensors can now alert councils when bins need emptying. Wikimedia

Sensors in public spaces can help create cities that are both smart and sociable

Researchers are installing sensors to collect data about the use of public spaces. This can improve the management and public amenity of these places, but will users see the technology as intrusive?
Very wet weather is likely to persuade many regular cyclists and walkers to travel instead by car if they can. This is Bondi Junction after a storm hit Sydney. David Moir/AAP

Too wet? Too cold? Too hot? This is how weather affects the trips we make

The relationship between weather and our travel choices is complicated. We can’t change the weather, but, with many other factors in play, good policy and design can reduce its impacts.

Building for the community is a win for the Gold Coast Games

The Gold Coast is mostly relying on existing assets, and most refurbishments and extensions were completed long before the Games, meaning the community has been able to use these facilities.
The research shows that barring people with a history of drug offences from public housing won’t reduce the risks of harm as NSW minister Pru Goward argues. Chris Pavlich/AAP

Public housing ban on people with drug records likely to do more harm than good, research tell us

The evidence is clear on the sort of support that is needed to reduce the harms of drug use. A punitive approach that denies people a second chance makes it more likely they will reoffend.

Lessons not learned: Darwin’s paying the price after Cyclone Marcus

After Cyclone Tracy, you’d expect Darwin of all cities to be ready for the next one. But as the clean-up after Cyclone Marcus continues, it’s clear more must be done to increase the city’s resilience.

Future ‘ocean cities’ need green engineering above and below the waterline

Artificial islands that are now mushrooming across the ocean are regarded as ‘engineering marvels’. But, little attention is paid to how these human-made structures affect sea life.
The Commonwealth Games is often dubbed the ‘friendly games’, but its history shows that friendliness applies only to ‘the right sort of people’. AAP

The Commonwealth Games of exclusion: what are authorities so afraid of?

Preparations for next month’s Commonwealth Games on the Gold Coast are pushing homeless people out of town, and out of the state. Sadly, that’s not unusual for events of this sort.
Flint, Mich., has one of the highest crime rates in the country for a city of its size. One neighborhood has found a novel way to fight back. Carlos Osorio/AP Images

Want to fight crime? Plant some flowers with your neighbor

Crime is way down in one Flint, Michigan, neighborhood, where locals have teamed up to revamp neglected public spaces. Here, why ‘busy streets’ can prevent violence and save cities money.
Third places are most effective when, like Waverley Community Garden in Sydney, they appeal to people of all ages and backgrounds. d-olwen-dee/flickr

Many people feel lonely in the city, but perhaps ‘third places’ can help with that

Third places are shared spaces where people can informally socialise. As a potential antidote to the modern scourge of loneliness, it’s worth asking what makes the best of these places tick.

Cycling and walking are short-changed when it comes to transport funding in Australia

New analysis reveals just how little is spent on cycling and walking projects around Australia. No state’s spending on cycling is more than 1.5% of its road funding.
Jakarta’s traffic system is one of many facets of the city that could be improved by smart cities technologies, but at what cost? Vasenka Photography/Flickr

Three scenarios show we have to think carefully about ethics in designing smart cities

Governments are using Big Data to design improvements and upgrades of cities. But ethical questions need to be considered, lest we end up jeopardising citizens’ privacy or deepen social inequalities.
