Small and medium-sized cities (SMCs) are becoming the new frontiers of global urban growth and population change. Yet, they are overlooked in the policy and scholarship discourses about urban futures, particularly urban planning for resilient futures. This handbook aims to increase attention to the resilience of SMCs and explore the unique challenges they face, as well as provide practical recommendations for built environment practitioners to understand and respond to these challenges in global contexts. Chapters cover a range of important topics on the different dimensions of urban resilience such as climate-induced risks, heat resilience planning, access to urban infrastructure and services, socio-environmental inequities, urban safety, health resilience, walkability, and more. Contributors discuss ways to enhance policy and planning efforts to address these challenges and advocate for the need to pay attention to SMCs when promoting urban resilience to avert the risks often manifested in large cities. This handbook transcends disciplinary boundaries and expertise, bringing together a diverse range of contributions from scholars and practitioners in over fifteen countries across Africa, Asia, North and South America, Europe, and Oceania to counter the apparent paucity of attention on SMCs in the global resilience agenda. This handbook is essential for scholars and practitioners working in the built environment, such as city and regional planning, public policy, public health, environmental science, architecture, landscape architecture, urban design, spatial planning, and geography.
