The world is becoming more urbanized. This affects how we live and how we think. There are both similarities as well as significant differences in dealing with this trend, in different parts of the world.

OVER half of the world's population lives in cities. There are more, and bigger, cities than ever before. Why, then, are we so wary of them?

Alastair Donald and Austin Williams are two architecture critics who wanted to respond to critics of urbanisation. Their book, "The Lure of the City", is a collection of essays that seeks to explore the role cities play as engines of social change and creativity.
