In 1980, the dominance of the American and Japanese economies was reflected by the world’s two leading megacities being Tokyo and New York City. But in 2025, the picture will be very different with seven of the world's top ten megacities being located in Asia. These graphs provide a fascinating view of the anticipated growth of the world’s major cities over the next fifteen years.
The planning and growth of Asian cities will have important implications for the rest of the world. Cities cover 2% of the earth's surface, host more than 50% of the world's population, account for 75% of energy consumption and are responsible for up to 80% of carbon-dioxide emissions. An article on the BBC website by Carlo Ratti and Kristian Kloeckl from MIT Senseable City Lab highlights how these cities will have to rely on new technologies and the inventiveness of billions of citizens to innovate in ways that will avoid repeating the urban mistakes of the 20th Century - only on a larger scale.
