The title of this book comes to our aid in that it enables us to limit the field of possible definitions to the sphere of relations existing between the landscape project and the city project. When we state the two terms city and landscape separately, we are implicitly acknowledging a detachment between two entities that tradition has considered inseparable. Other theoretical reflections, applications and best practices explore the involvement of the territory in the organisation of both urban life and landscape; how changes within the city have opened up traditional concepts of centrality towards new forms of centrality, as well as towards more environmental interpretations of centrality. The articles in this volume are by scholars with backgrounds in philosophy, architecture, urban and landscape planning, who have a particular interest in and experience of the city project at various operative scales.
