Cities have been experiencing a moment in the cultural spotlight in the last few years. There is more discussion and even celebration of cities than ever before. Newspapers and magazines are starting websites dedicated to global urban issues, university researchers and technology companies are turning their attention to ‘smart cities’, and there are even popular documentary movies, reality shows and musicals all about city planning. India, still mostly rural, has just elected a new Prime Minister who promises urban redevelopment and ‘new-age cities’, and it is no longer shocking to hear that China's proposed urbanization budget runs in the trillions of dollars.
Why has this urban moment come about now? Several trends, some in the developing world and others in wealthier countries, seem to have converged lately. It is interesting to step back and examine these trends, before thinking about where we go from here.
