Here is a neat tool (created by Benjamin Td) that allows you to quickly see how far you can travel in Europe by rail in 5 hours. The way it works is that you just hover over a train station and then the relevant isochrone will show up. Above is what that looks like for Paris' Gare de Lyon, which has one of if not the largest catchment areas from what I can tell after playing around with the tool for a few minutes. The data being used to power this map is from Deutsche Bahn. And if there's a transfer on any of the routes, the tool assumes you can make that happen within 20 minutes, which may or may not be realistic. Regardless, it's fascinating to see just how connected (or disconnected) some cities are. It's also a shameful reminder that a North American version wouldn't be nearly as impressive.
Well here are some interesting figures (via MIT Technology Review):
In the past two decades, about 400 million people moved into China's cities -- so more than the entire population of the United States
By 2035, about 70% of China's entire population is expected to be urban (up from 60% today and up from 30% two decades ago)
To accommodate this scale of growth, China's national urban development approach has shifted to something that now revolves around city clusters, or megalopolises (term coined by French geographer Jean Gottmann back in the 1950s to describe the Boston-Washington corridor in the Northeastern US)
By 2035, there are expected to be five major city clusters (see above)
One of the reasons for this is to improve cooperation across the various clusters -- less competition and less redundancy
But it's also about creating smaller more manageable cities -- is this what one needs to do after a certain scale, go polycentric?
To service these clusters, China is rolling out a network of 16 new high-speed rail lines
By 2035, China expects to have 200,000 kilometers of rail, with a third of it being high-speed -- assuming this happens, China will be home to 60% of the world's high-speed rail coverage
Current cost estimates for the construction of this network comes out to about US$150 million per kilometer
1-2-3 Rule: The plan is that everyone should be able to get around a city within 1 hour; a city cluster within 2 hours; and travel between the country's clusters inside of 3 hours
China is building.
For all of us who are involved in the building of cities, it is important to remember that cities emerge and thrive as a result of economic purpose. Take, for example, Sao Paulo. Once one of the poorest of Portuguese colonies, it is today the largest city in the southern hemisphere and one of the largest and most diverse urban agglomerations in the world.
How did all of this happen? It was probably because of coffee.
Brazil is the largest producer of coffee in the world. And it has owned this title for some 150 years. The best areas to grow coffee (as a result of climate, I'm told) are in the southeast part of the country, in and around Sao Paulo and Rio de Janeiro. The inland state of Minas Gerais is the biggest producer.
But here's the thing. Rio de Janeiro is along the coast and Sao Paulo is not, though as of 1869 it had been connected to the port of Santos by rail. This geographical feature made Sao Paulo a logical place for rail to converge as it made its way from the coffee plantations in the interior of the country to the coast, and then out to the rest of the world.
Coffee was the economic purpose. And it was facilitated by Brazil's longstanding use of slave labor.
In 1888 that changed. Slavery was abolished, giving Brazil the dubious distinction of being the last country in the Western world to do so. The problem is that the coffee industry relied heavily on this labor. So to fill this void and keep the coffee industry happy, a deliberate effort was made to increase immigration.
From 1870 to 2010, about 2.3 million immigrants settled in the state of Sao Paulo, many from Italy and Japan. Today, about half of the city is thought to have at least some Italian ancestry. And it is generally believed that it was this significant influx of immigrants that helped the city to industrialize in the way that it did.
Big and diverse. And coffee probably had a lot to do with it.
