In town and in country there must be landscapes where we can walk in safety, pick fruit, cycle, work, sleep, swim, listen to the birds, bask in the sun, run through the trees and laze beside cool waters.

From 50 centuries, we can learn about the close relationship between garden design and urban design, because both arts involve the composition of buildings with paving, landform, water, vegetation and climate.

Having lasted for 4,000 years, the use of nature's materials to express ideas about nature may be expected to continue. The best garden designs are produced with an awareness of the art, science, history, geography, philosophy, social habits and construction techniques of their period.

Humphry Repton, the leading garden theorist of the nineteenth century, defined a garden as 'a piece of ground fenced off from cattle, and appropriated to the use and pleasure or man: it is, or ought to be, cultivated and enriched by art'.

The tragedy of feminine design is that it receives so little official support. Most of the world's design schools, having been organized by men, encourage a masculine approach, even when they are run by women. Yet many designers who are male in the biological sense have a feminine approach to design.

Many of the world's best-designed cities have been inspired by garden concepts.

Landscape planners will have the opportunity to make sculptured roofscapes, so that cities appear to be verdant hills and valleys. Streets will become shady routes carved through the undergrowth. Roofs will become mountain tops. People will become ants.
