Something to learn from Shadow Cities

In Prospect, Stewart Brand on what we can learn from Shadow Cities

There are plenty more ideas to be discovered in the squatter cities of the developing world, the conurbations made up of people who do not legally occupy the land they live on—more commonly known as slums. One billion people live in these cities and, according to the UN, this number will double in the next 25 years. There are thousands of them and their mainly young populations test out new ideas unfettered by law or tradition. Alleyways in squatter cities, for example, are a dense interplay of retail and services—one-chair barbershops and three-seat bars interspersed with the clothes racks and fruit tables. One proposal is to use these as a model for shopping areas. “Allow the informal sector to take over downtown areas after 6pm,” suggests Jaime Lerner, the former mayor of Curitiba, Brazil. “That will inject life into the city.”
