Although most cities seem to form by accident, for
thousands of years some of them have been designed.
Whether for defence, beauty, or practicality, urban
designers have imposed their ideas of what a city
should be about. But ideas are subject to changing
needs and fashions. Centuries ago, a moat or a
castellated wall would have been essential. Now,
greenery is in vogue. While existing cities look for ways
of becoming more environmentally friendly, a number of
new ones are planned that intend to be totally green.

in progress. What emerges will not necessarily translate
well elsewhere. Each green city is unique, and getting it
to work depends on its location and economy.
