Figure of the week: Africa is home to the 10 fastest growing cities in the world

The United Nations Department of Economic and Social Affairs projects that the world’s 10 fastest growing cities, between 2018 and 2035, will all be in Africa. The visualization below first maps the location of the fastest growing cities in the world with a population greater than 2.5 million. Interestingly, many of the fastest growing African cities are specifically located on the Gulf of Guinea including Lagos, Abuja, Abidjan, Doula, and Kumasi.

What You Can Learn About the Future of Cities from Wakanda – CityLab

Citylab has pulled together a Wakanda Reader, or online bibliography of sorts, to indulge those who are interested in the larger questions around urbanism implicated in Black Panther. We would call it a syllabus, but there are already several syllabi available—this #WakandaSyllabusfrom Walter Greason, an economic history professor at Monmouth University and founder of the International Center of Metropolitan Growth, is particularly good. This Wakanda curriculum for middle school grades from school teacher Tess Raker has also been making the rounds.

As for what else has been circulating, here’s an exhaustive, still-living-and-growing list of articles that build upon the Wakandan mystique:

Opinion | A New Map for America – The New York Times

From 2016 but even more salient today. Compare to Trump’s Infrastructure Plan once released and see where the plan misses the key points.

Congress was once a world leader in regional planning. The Louisiana Purchase, the Pacific Railroad Act (which financed railway expansion from Iowa to San Francisco with government bonds) and the Interstate System of highways are all examples of the federal government’s thinking about economic development at continental scale. The Tennessee Valley Authority was an agent of post-Depression infrastructure renewal, job creation and industrial modernization cutting across six states….

What would this approach look like in America? It would start by focusing not on state lines but on existing lines of infrastructure, supply chains and telecommunications, routes that stay remarkably true to the borders of the emergent super-regions, and are most robust within the new urban archipelagos…

Where possible, such planning should even jump over international borders. While Detroit’s population has fallen below a million, the Detroit-Windsor region is the largest United States-Canada cross-border area, with nearly six million people (and one of the largest border populations in the world). Both sides are deeply interdependent because of their automobile and steel industries and would benefit from scaling together rather than bickering over who pays for a new bridge between them. Detroit’s destiny seems almost obvious if we are brave enough to build it: a midpoint of the Chicago-Toronto corridor in an emerging North American Union.

To make these things happen requires thinking beyond states. Washington currently provides minimal support for regional economic efforts and strategies; it needs to go much further, even at the risk of upsetting established federal-state political balances. A national infrastructure bank, if it ever gets off the ground, should have as part of its charter an obligation to ignore state lines when weighing

Trees can make or break city weather — ScienceDaily

 

Even a single urban tree can help moderate wind speeds and keep pedestrians comfortable as they walk down the street, according to a new University of British Columbia study that also found losing a single tree can increase wind pressure on nearby buildings and drive up heating costs.

Ties in with The Hidden Life of Trees by Peter Wohlleben (definitely worth reading) where he discusses how trees in a forest create their own micro-climate and provide each other with physical support against wind and storms. But also read where he discusses the plight of urban trees forced to live without the forest community that they evolved for.

Opening day for Detroit’s QLINE M-1 rail – National Resources & Technical Assistance For Transit-Oriented Development

 

The QLINE M-1 light rail line is scheduled to finally open in Detroit this weekend, with a full weekend of festivities to celebrate. The line will permanently connect several major destinations in greater downtown Detroit, and improve access to jobs and services for thousands of residents along the corridor. The project has already catalyzed more than $1 billion in real estate investment along the corridor. All told, the economic impact of transit-oriented development is expected to top $3.5 billion with

How One of the World’s Densest Cities Has Gone Green

Picture of SuperTrees at Gardens by the Bay

Symbol of Singapore, these “Supertrees” belong to a display at the 250-acre Gardens by the Bay. The high-tech structures range from 80 to 160 feet and collect solar energy to power a nightly light show. They have a softer side too: their trunks are vertical gardens, laced with more than 150,000 living plants.

New York’s L Train Closure Effects on Transit, Mapped – CityLab

A useful tool not just for L-Train Hell but understanding commute times from various locations in the City and hopefully additional cities.

Endless train delays and calcifying surface traffic have lately painted the New York City transit experience a deep shade of red. Soon, commuters will unlock a fresh level of hell when the tunnel housing the L train closes for 18 months to address Hurricane Sandy damage. Starting as early as 2019, the shutdown of the tunnel—and all L train stations west of Bedford Avenue in Brooklyn—will directly impact the 250,000 riders who shuttle between Brooklyn and downtown Manhattan every day.

The map isn’t only great for arguing about whose commute is about to suck the most. You can also debate how travel options compare, for better and for worse, as they presently are. Dropping a single pinpoint onto the map reveals, in shaded color, relative access by train and bus from that location to everywhere else in the city. Bed-Stuy is a transit-friendly place to live, with lots of places easily accessible:
