This book follows the exhibition Life Takes Precedence (La Préséance du vivant) first presented as part of the second Biennale of Architecture and Landscape of the Île-de-France region. Planetary Gardener sets out the main concepts developed by French gardener, botanist and writer Gilles Clément and landscape architects Coloco, showcasing how we can live in harmony with nature and appreciate the ecosystem in all its diversity. Featuring a varied selection of landscape-related experiments as well as tools and concepts meant to inspire action, this publication invites the reader to adopt the point of view of both gardener and guardian.
