From its origins in nineteenth-century parks green, infrastructure has been an ever-evolving component of cities. This chapter makes some observations based on a number of key trends in society and emerging patterns of green infrastructure provision to make some suggestions for the future. It looks at how our cities and their citizens are changing and the response required if green infrastructure, in terms of its form and function, is to remain relevant. In addition to our cities shaping green infrastructure, it in turn has a fundamental role to play in future-proofing our cities from challenges, such as climate change, and threats to natural ecosystems and their services on which our health and well-being depend. The management of green infrastructure is also likely to evolve the future, particularly in times of austerity, and require ever greater degrees of collaboration between professions and sectors. However, the future, it is argued, also holds new opportunities for green infrastructure, for example, in terms of new technologies to improve is delivery, streamline its management and monitoring, and facilitate community involvement. What is clear is that green infrastructure will need to be a flexible and dynamic resource that is capable of adapting to cities of the future.

Green infrastructure 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. It then provides a comprehensive and authoritative account for those seeking to achieve sustainable green infrastructure in urban environments of how to plan, design and implement green infrastructure at different spatial scales.
The term green infrastructure encompasses a broad range of spaces and other vegetated elements. These may include, for example, individual street trees, green roofs and walls, green corridors, through to amenity spaces, parks and gardens, and spaces for water management. These should, ideally, come together to form a network of connected and complementary features that deliver a range of ecosystem services. This chapter explores the types of green infrastructure that comprise this network based on their form and function. This typology is further developed to consider the characteristics of green infrastructure including management, size and scale, ownership and use. The different functions that each type of green infrastructure may be expected to provide are then presented, categorised as social and cultural, ecological or economic functions, although the multifunctional nature of most types of green infrastructure is emphasised. Finally, it looks at how this multifunctional green infrastructure can be achieved, arguing that this needs to be considered from the design stage and at all spatial scales if a strategic network is to be delivered.
