      The Urban Climacteric

      We live in the age of the city. The city is everything to us – it consumes us, and for that reason we glorify it.

      Sometime in the next year or two, a woman will give birth in the Lagos slum of Ajegunle, a young man will flee his village in west Java for the bright lights of Jakarta, or a farmer will move his impoverished family into one of Lima’s innumerable pueblos jovenes. The exact event is unimportant and it will pass entirely unnoticed. Nonetheless it will constitute a watershed in human history, comparable to the Neolithic or Industrial revolutions. For the first time the urban population of the earth will outnumber the rural. Indeed, given the imprecisions of Third World censuses, this epochal transition has probably already occurred.

The earth has urbanized even faster than originally predicted by the Club of Rome in its notoriously Malthusian 1972 report Limits of Growth. In 1950 there were 86 cities in the world with a population of more than one million; today there are 400, and by 2015 there will be at least 550.² Cities, indeed, have absorbed nearly two-thirds of the global population explosion since 1950, and are currently growing by a million babies and migrants each week.³ The world’s urban labor force has more than doubled since 1980, and the present urban population – 3.2 billion – is larger than the total population of the world when John F. Kennedy was inaugurated.⁴ The global countryside, meanwhile, has reached its maximum population and will begin to shrink after 2020. As a result, cities will account for virtually all future world population growth, which is expected to peak at about 10 billion in 2050.⁵

      Megacities and Desokotas

      Ninety-five percent of this final buildout of humanity will occur in the urban areas of developing countries, whose populations will double to nearly 4 billion over the next generation.⁶ Indeed, the combined urban population of China, India, and Brazil already roughly equals that of Europe and North America. The scale and velocity of Third World urbanization, moreover, utterly dwarfs that of Victorian Europe. London in 1910 was seven times larger than it had been in 1800, but Dhaka, Kinshasa, and Lagos today are each approximately forty times larger than they were in 1950. China – urbanizing “at a speed unprecedented in human history” – added more city-dwellers in the 1980s than did all of Europe (including Russia) in the entire nineteenth century!⁷

      (population in millions)

The most celebrated phenomenon, of course, is the burgeoning of new megacities with populations in excess of 8 million and, even more spectacularly, hypercities with more than 20 million inhabitants – the estimated urban population of the world at the time of the French Revolution. In 2000, according to the UN Population Division, only metropolitan Tokyo had incontestably passed that threshold (although Mexico City, New York and Seoul-Injon made other lists).⁹ The Far Eastern Economic Review estimates that by 2025 Asia alone might have ten or eleven conurbations that large, including Jakarta (24.9 million), Dhaka (25 million), and Karachi (26.5 million). Shanghai, whose growth was frozen for decades by Maoist policies of deliberate underurbanization, could have as many as 27 million residents in its huge estuarial metro-region. Bombay, meanwhile, is projected to attain a population of 33 million, although no one knows whether such gigantic concentrations of poverty are biologically or ecologically sustainable.¹⁰

      The exploding cities of the developing world are also weaving extraordinary new urban networks, corridors, and hierarchies. In the Americas, geographers already talk about a leviathan known as the Rio/São Paulo Extended Metropolitan Region (RSPER) which includes the medium-sized cities on the 500-kilometer-long transport axis between Brazil’s two largest metropolises, as well as the important industrial area dominated by Campinas; with a current population of 37 million, this embryonic megalopolis is already
