Towards territorial transition is a plea to large-scale decarbonizing. It presents new spatial strategies, concepts, and approaches for shaping large-scale and transnational developments in architecture and urban design towards decarbonization and ecological transition. The contributions investigate interactions between ecological and resource-related systems and landscapes. They also explore potential solutions to address and deal with the dramatic threats posed by climate change and the emerging social crisis.The book introduces six basic notions of territorial transition -territory, scale, transition, ressource, platform, and uncertainty – and visualizes them with spatial strategies elaborated at the Ecole nationale supérieure d'architecture Versailles, International master « Invisible metropolis », and at Graz University of Technology, Institut für Städtebau. Moreover, it presents a selection of transnational projects of territorial transition, such as Luxembourg in Transition, Rheinisches Revier, Greater Geneva, T.OP Noordrand, Amiter Tours and Raumbilder Lausitz.
