Why do we need suburbs between city and rural life? Perhaps the fictional Wakanda offers an answer:

“One of the things I love about Wakanda, if you notice, if you watch ‘Black Panther’ carefully, there’s the city, the city’s got all this mass transit and all this housing parks and all this stuff,” explained Chakrabarti, who wrote a book called “A Country of Cities: A Manifesto for an Urban America.” “And the moment you leave the city, you’re in farmland. And there’s this connection between rural life and urban life.”

He added: “I just think that is a really interesting paradigm to think about people, either living in super dense circumstances or really living in true rural hinterland and doing the things that we need everyone to do in farmland, which is grow our food and all of that stuff. And it would mean you would use a lot less land on this planet at the end of the day.”…

Whether major American cities ever transform from where we are today — heavily suburbanized and car-dependent — remains to be seen. But all we have to do is look to Wakanda for an idea of how our cities of the future could work.

I would argue that the American suburbs are popular, in part, because they appear to offer both features of city and rural life. Suburbanites like access to housing, jobs, and cultural amenities but they also want smaller communities and proximity to nature. With cars, they can on their own schedule access these features.

I remember the first time I saw in person this cleaner break between a city and rural areas. I had a chance to spend several days in Tokyo while in college. On one day, we took a train out of the city. As we moved at a high speed away from the city center, we suddenly moved from the denser city to fields. The same break could be seen from the air when flying in and out of the city.

This is not typically the case in the United States where suburbs might stretch for dozens of miles from the city limits before finally dwindling out. Moving more people into denser locations would indeed free up land or freezing development in metropolitan regions within an established boundary would do the same.
