The prolific and controversial urban critic, Mike Davis, has a new book Planet of Slums. It is based upon his article Planet of Slums in New Left Review (March-April 2004). In Planet of Slums he writes:
There may be more than quarter of a million slums on earth. The five great metropolises of South Asia (Karachi, Mumbai, Delhi, Kolkata and Dhaka) alone contain about 15,000 distinct slum communities with a total population of more than 20 million. An even larger slum population crowds the urbanizing littoral of West Africa, while other huge conurbations of poverty sprawl across Anatolia and the Ethiopian highlands; hug the base of the Andes and the Himalayas; explode outward from the skyscraper cores of Mexico, Jo-burg, Manila and São Paulo; and, of course, line the banks of the rivers Amazon, Niger, Congo, Nile, Tigris, Ganges, Irrawaddy and Mekong. The building blocks of this slum planet, paradoxically, are both utterly interchangeable and spontaneously unique: including the bustees of Kolkata, the chawls and zopadpattis of Mumbai, the katchi abadis of Karachi, the kampungs of Jakarta, the iskwaters of Manila, the shammasas of Khartoum, the umjondolos of Durban, the intra-murios of Rabat, the bidonvilles of Abidjan, the baladis of Cairo, the gecekondus of Ankara, the conventillos of Quito, the favelas of Brazil, the villas miseria of Buenos Aires and the colonias populares of Mexico City. They are the gritty antipodes to the generic fantasy-scapes and residential themeparks—Philip K. Dick’s bourgeois ‘Offworlds’—in which the global middle classes increasingly prefer to cloister themselves.
