Towards Territorial Transition presents new spatial strategies, concepts, and approaches for shaping large-scale and transnational developments in architecture and urban design towards decarbonisation 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 terms of territorial transition — territory, scale, transition, resource, platform, and uncertainty — and visualises them with spatial strategies elaborated at the École nationale supérieure d’architecture Versailles and at Graz University of Technology. Moreover, it presents a selection of transnational projects of territorial transition, such as Luxembourg in Transition (Luxembourg / France), Grand Genève (Switzerland / France), and Top Noordrand (Brussels / Flanders).
