Beyond the urgency of rethinking XX-century urbanization characterized by endless structural expansion strategy, we need to engage urban systems by means of emerging concepts of adaptability and systemic transitions due to climate change effects. Emission reduction and spatial compactness, reuse and recycle, flexibility and complex balances have a profound impact on the spatial dimension and the quality of the urban environment, therefore architectural and urban design are deeply involved in facing ecological transitions and envisioning new strategies to implement the quality of the cities we live in. How to face these emergent challenges? What are the ongoing design strategies for climate change effects? what will be the role of design in transitional systems? Do we recognize it as an opportunity to improve the public space? Design Actions for Shifting Condition is a collaborative effort, and aims to present, from an architectural and urban design point of view, methodologies, practices, and approaches to overcome existing and new fragilities for Cities in Times of Transition. @en
