Megacity crisis

Other Names:
Negative environment of megacities

Megacities are largely a phenomenon of the developing world. It is predicted that in a few years' time, the urban population of the developing world will be twice as big as that of the industrialized countries.


Megacities now tend to be described as cities having more than 10 million inhabitants. By the year 2015, the 10 largest cities in the world will be in Asia, Latin America and Africa. While Tokyo, with 28.7 million inhabitants, is expected to be the largest and only one among the world's megacities located in the developed world, the remaining nine will all be in developing countries: Bombay, India (27.4 million); Lagos, Nigeria (24.4); Shanghai, China (23.4); Jakarta, Indonesia (21.2); Sao Paulo, Brazil (20.8); Karachi, Pakistan (20.6); Beijing, China (19.4); Dhaka, Bangladesh (19); and Mexico City, Mexico (18.8).
