Our societies have become very crisis-prone. This book explores crises and the methods of anticipation, management and reconstruction, and considers a risk-crisis-territorial development continuum. The aim is to better understand a widely used concept and clarify the methods of action in the field of crisis management. The different forms of learning proposed to better face future crises are also questioned. This book invites us to analyze the resources available to support crisis management and reconstruction, and consider the unequal access to these resources in different territories in order to design future territorial strategies. This often results in a form of territorial inertia after the crises. However, some innovate, imagine renewed territories, prepare for reconstruction, or even recompose territories now in order to make them more resilient. The crisis can then be the driving force or the accelerator of these changes and contribute to the emergence of new practices, or even new urban and territorial utopias.
