Book excerpt: Green infrastructure encompasses many features in the built environment. It is widely recognised as a valuable resource in our towns and cities and it is therefore crucial to understand, create, protect and manage this resource. This Handbook sets the context for green infrastructure as a means to make urban environments more resilient, sustainable, liveable and equitable. Including state-of-the-art reviews that summarise the existing knowledge as well as research findings, this Handbook provides current evidence for the beneficial impact of green infrastructure on health, environmental quality and the economy. It discusses the planning and design of green infrastructure as a strategic network down to the individual features in a neighbourhood and looks at the process of green infrastructure implementation, emphasising the importance of collaboration across multiple professions and sectors. This comprehensive volume operates at multiple spatial scales, from strategic networks at the regional level to individual features in neighbourhoods, with international case studies used throughout to illustrate key examples of good practice. This collection of expert contributions will be invaluable to students and academics in the fields of planning, urban studies and geography. Practitioners and policy-makers will also find the policy discussion and examples enlightening.
