What knowledge is indispensable for the landscape architect? The answers to this question are as diverse as landscape architecture itself. In this book 50 landscape architects from Europe, North and South America, Asia and Australia each give five responses. These include practitioners and teachers, young start-ups as well as internationally established firms. The publication illustrates the complex and dynamic nature of the discipline, and presents a diverse cross-section of the core expertise of this field. At the same time, it allows the reader to trace the individual attitudes into which geographical conditions, social contexts and political circumstances flow. Each of the 250 statements is presented on a double page and illustrated by a picture.
