In the face of increasing climate disruption, this book provides a design-centered investigation of how cities might adapt, recover, and prosper. It positions resilience not as a technical add-on, but as a fundamentally social, ecological, and spatial practice that must be embedded across scales, from materials and buildings to neighbourhoods, infrastructures, and urban systems. The chapters show how climatic threats including heat, flooding, water scarcity, and catastrophic shocks are changing our conception of urban space in a variety of worldwide situations. The contributions demonstrate how nature-based solutions, water-sensitive planning, circular construction, and regenerative urbanism are now inextricably linked to resilient design. They also show how new technologies like geographic simulation, XR environments, and digital twins are increasing the designer's ability to foresee unpredictability and test flexible solutions before putting them into practice. The main issue addressed is evident: urban development practice still has difficulty converting resilience concepts into spatial, material, and community-grounded design activity, even in the face of increased awareness of climate risk. In response, this book compiles experimental techniques, conceptual developments, and empirical research that show how resilience may be operationalized in actual projects and locations. It focuses on transferable tactics that can influence professional practice, education, and policy, such as regenerative neighbourhood models, nature-based drainage, climate-responsive public spaces, and circular recovery. Resilient by Design ultimately argues that the future of cities depends on re-aligning ecological systems, technological innovation, and social inclusion through design thinking. It provides an interdisciplinary knowledge base and a forward-looking agenda for shaping climate-ready urban environments. The book is intended for researchers, urban designers, architects, planners, landscape architects, and policymakers engaged in climate-resilient and sustainable urban development.
