This publication compiles the results of the SpaceWatch event 2008. The first edition has taken place in Lausanne on May 15th, 2008. The present book is composed of two parts. Part I presents the scientific comments on the press review highlighting the controversies in public debate on the Swiss territorial development while Part II presents the 8 proposals that came out of the workshop. The main formulations on which the invited specialists agreed are illustrated by significant sentences taken on the fly throughout the day. This book sets out the eight proposals that came out of the workshop, framed by both the personal comments later produced by the experts as well as excerpts from the actual discussions. With a view to building a coherent approach to spatial development, SpaceWatch intends to organize further workshops to discuss these and other ideas, encouraging widespread participation in what is intended to become a permanent forum for public debate.
