Abstract
Green infrastructure (GI) includes an array of products, technologies, and practices that use natural systems—or designed systems that mimic natural processes—to enhance environmental sustainability and human quality of life. GI is the ultimate source of the ecosystem services which the biotic environment provides to humanity. The maintenance and enhancement of GI to optimise the supply of ecosystem services thus requires conscious planning. The objective of this thematic issue is to publish a cross-section of quality research which addresses how urban planning can contribute to the conservation, management, enhancement, and creation of GI in the city. The terms of reference include the technical, economic, social, and political dimensions of the planning/GI nexus. Here we offer a brief overview of the articles published in this collection, and consider where policy, planning, and design relating to urban GI may be heading in the future.
Highlights
Urban green infrastructure (GI) has been described variously as comprising a cross-city network of greenery, or a more loosely defined assemblage of diverse green elements such as parks, domestic gardens, street trees, and green roofs and walls
We apply a broad definition, adopted from a recent project to develop an evidence base for embedding ecology into urban decisionmaking: GI is “an adaptable term used to describe an array of products, technologies and practices that use natural systems—or designed systems that mimic natural processes—to enhance environmental sustainability and human habitability” (Davies et al, 2017, p. 31)

Summary
Urban green infrastructure (GI) has been described variously as comprising a cross-city network of greenery, or a more loosely defined assemblage of diverse green elements such as parks, domestic gardens, street trees, and green roofs and walls. To pose the question from a different angle, GI is the ultimate source of the ecosystem services which the biotic environment provides to humanity. The maintenance and enhancement of GI to optimise the supply of ecosystem services for the city requires conscious planning, from room to region (Beatley, 2011). The objective of this thematic issue is to publish a cross-section of quality research which addresses how urban planning can contribute to the conservation, management, enhancement, and creation of GI in the city. The terms of reference include, but are not limited to, the technical, economic, social, and political dimensions of the planning/GI nexus
