This unique, multilingual, encyclopedic dictionary in two volumes covers terms regularly used in landscape and urban planning, as well as environmental protection. The languages are American and British English, Spanish (with many Latin-American equivalents), French, and German. The encyclopedia also provides various interpretations of the terms at the planning, legal or technical level, which make its meaning more precise and its usage clearer.

Groups of German and English words in a particular subject area are illustrated on the same or opposite page.

Organized thematically, this book tells the story of the European encyclopedia from 1650 to the present.
