Cities at Night
The NASA Earth Observatory has a huge 'collection' of beautiful photographs. This collection includes some photographs of cities at night taken by astronauts from the International Space Station.
Astronauts circling the Earth have the wonderful vantage point of observing the nighttime Earth from 350-400 kilometers above the surface, taking in whole regions at once. Onboard cameras and a bit of experimentation allow astronauts to take highly detailed images of our cities at night and share them with the rest of us.
Brasília at night is the current image of the week. They say that "Brasília is widely considered to be one of the best examples of 20th century urban planning in the world." I'll try to take that as a complement.

Some other photographs: Montreal, Dubai, Las Vegas, Los Angeles (this video is great), London, Houston, Northern China, Buenos Aires, São Paulo. [Hat tip to The Map Room]

São Paulo Urbanization (1957-2007)
Folha.com (what could be considered the equivalent of the New York Times here in Brazil) is publishing special articles on the 457º Anniversary of the City of São Paulo.
The articles are written in Portuguese. But you can enjoy a few images of São Paulo Urbanization here.

You can visualize other areas here (lazy link).
There is also a "before and after" session with pictures of São Paulo central area.
ps. Happy Birthday São Paulo !

Counterintuitive trues about urban transport
Enrique Peñalosa (former mayor of Bogotá) presented a pleasant lecture at LSE titled: “Politics, Power, Cities”. Listen to podcast here (approx 91 min).Here are some interesting snippets (They might look obvious to some of you. But do they look obvious to you mayor?)
- What creates traffic is not the number of cars, is the number of trips and the length of trips.
- Mobility and Traffic Jams are total different problems that require different solutions. Reducing car use is different than solving Traffic Jams.
- To solve Traffic Jams is, in fact, to facilitate car use.
- The only way to solve Mobility is with public transport. This will solve Mobility but not Traffic Jams.
- The only way to solve Traffic Jams is restricting car use. And the most obvious way to restrict car us is restrict parking.
- To park is not a Constitutional right anywhere.
- For public transport the most important thing is Density.
*ps2. He didn't say much (nothing) about land use... I missed that.

Assorted links on Chinese Urbanization
- Urban China in 30 frames. Here. (via Moving Cities)
- The new issue of the Journal of Transport and Land Use (JLUT) focuses on China. Here!
- Dan Steinbock on Chinese urbanization and labor force supply. Here.excerpt: "The urbanization that took almost a century in the West is occurring in a decade or two in China. In 1979, Shenzhen was still a poor fishing village with some 20,000 inhabitants. In 2009, it had a population of 9 million, and income per capita exceeded $13,600, only $3,000 less than in Taiwan or South Korea."
- Lisa Gu on possible urban decentralization in China. Here.excerpt: "The shifts in the value of a hokou parallels another interesting shift: many migrant workers are returning to their hometowns much earlier. In the previous years, migrant workers would usually return home right before Lunar Chinese New Year, which typically falls in February, but a large number of them have started to return home in December this year. // The driving factor behind this change is that the cost of living in the cities has risen so dramatically over the past few years, and the money migrant workers earn barely covers their living costs. // Although China’s urbanization will likely continue, the patterns might increasingly be to smaller cities and towns. In this sense, China’s development may, sooner than any expected, begin to take on the dispersion pattern that has occurred in the Western countries for more than a half century.

The death of Modern Architecture(?)
Is Modern architecture dead?
Pratik Mhatre (Urban Planning Blog) posted the trailer for the documentary film "The Pruitt-Igoe Myth: an Urban History" . Here is the Trailler (and the documentary official website):
I didn't know of the existence of Pruitt–Igoe until this post. And now, thanks to wikipedia, I know that Pruitt–Igoe
- "was a large urban housing project first occupied in 1954 and completed in 1955 in the U.S. city of St. Louis, Missouri".
- "The complex was designed by architect Minoru Yamasaki, who also designed the World Trade Center towers."
- Furthermore, "The Pruitt–Igoe housing project was one of the first demolitions of modernist architecture and its destruction was claimed by postmodern architectural historian Charles Jencks to mark 'the day Modern architecture died'."
One particular point caught my attention: Pruitt–Igoe's collapse seems to be attributed exclusively to its modernist architecture. Isn't a too simplistic statement? Brasilia (a remarkable urban experiment) is doing fine so far (?is it?).
What could help us understand the different fates (failure and success) faced by modernist urban planning experiences ? [urban scale? capita income, and other sociodemographic characteristics?....]
These are some photos of Pruitt–Igoe back then.

Wolrd Balance
Ok. Now back to real world!
And talking about the world population, every now and then someone comes up with the overpopulation issue. Usually it is referred to as the "overpopulation problem".
"But one can also draw a different conclusion—that fixating on population numbers is not the best way to confront the future. People packed into slums need help, but the problem that needs solving is poverty and lack of infrastructure, not overpopulation. Giving every woman access to family planning services is a good idea—“the one strategy that can make the biggest difference to women’s lives,” Chandra calls it. But the most aggressive population control program imaginable will not save Bangladesh from sea level rise, Rwanda from another genocide, or all of us from our enormous environmental problems."
"The number of people does matter, of course. But how people consume resources matters a lot more. Some of us leave much bigger footprints than others. The central challenge for the future of people and the planet is how to raise more of us out of poverty—the slum dwellers in Delhi, the subsistence farmers in Rwanda—while reducing the impact each of us has on the planet."
