This book is almost a manual of "refusal landscapes," within the Italian context framed through an international approach, inside the multiplicity of the dross spaces of refusal, to extend and clarify the concept of abandoned spaces, beyond Alan Berger's approach. Projects and research are used to engage and interpret the current and future city, in its geographical structure, infrastructures and forms of settlement, and towards a new urban metabolism. This book recycles strategies and multi-scalar design approaches, multiple design actions in different contextual life cycles--physical, social, economic--processes and programs, alternative scenarios and unpredictable paths of the Hyper-Cycle and Drosscapes.
