Henri Lefebvre, The Right to the City — In brief, the right to the city is the right to the production of a city. The labor of a worker is the source of most of the value of a commodity that is expropriated by the owner. The worker, therefore, has a right to benefit from that value denied to them. In the same way, the urban citizen produces and reproduces the city through their own daily actions. However, the the city is expropriated from the urbanite by the rich and the state. The right to the city is therefore the right to appropriate the city by and for those who make and remake it.

Climate resilience: Has the time come to start demanding lighter-coloured streets in hotter climates?

At this stage, the challenge with climate change is not just preventing it from happening by cutting emissions. We also need to make our cities resilient to the climate change we've already locked in.

That's where lighter coloured paving for streets, rather than dark asphalt, can help:

"Sebastian Pfautsch doesn't hesitate when asked what he would change first to cool Australian cities in summer.

"And it's not what you might expect. It's not the seemingly endless expanse of black roofs, soaking up the sun beneath a shimmering haze.

"It's the roads. About a third of any outer suburb is thermally dense black asphalt that can reach 75 degrees Celsius, according to Professor Pfautsch, an expert on urban heat at the University of Western Sydney.

...

"Lighter-coloured roads may make intuitive sense, like wearing a white shirt on a hot day, but how effectively do they reduce surface and ambient air temperature?

"In 2020, two separate cool roads trials in Sydney and Adelaide set out to conclusively answer these questions.

"The Sydney trial, which took place at about 10 sites in the Western Sydney suburbs of Blacktown, Campbelltown and Parramatta, recorded an average surface temperature reduction of 5.6C and 2C for day and night respectively.

"For context, tree shade reduced the surface temperatures of roads by 16C."

@ajsadauskas @urbanism Bloody nimbys, whingeing about flood-plain housing. Not understanding the well-watered gardens, backyard canoeing, and free-range swimming the people enjoy.

@JamesAshburnerCBR @urbanism And, as anyone in the property game will tell you, what Sydneysiders want is a waterfront property with great views.

Well, thanks to Anthony, you can experience those water views without even leaving your living room or bedroom.

After all, your property can't get any closer to the water than being underneath it...

@ajsadauskas @urbanism Just need a bed-boat in your bedroom. Going fishing has never been easier.
