This book presents peer-reviewed articles from the UrbanPromo International Conference on “Designing in disorder - Designing disorder. Reorganizing Urban Fragility” held from 5 to 8 November 2024 at Florence in Italy. It highlights the issue of land management and its transformations through the use of soft policies and soft power practices: informal tools that progressively complement the ordinary, more formal and constraining tools and processes of planning and design, allowing for a greater variety of possible outcomes, a reduction in time and an increase in the final quality of results.This book therefore reviews these experimental practices and explores how much of this modality can be the pathway for updating the discipline of spatial governance in Europe.
