Sustainability Assessment of Urban Infrastructures

Abstract

The “renaturing” of cities through an increased emphasis on the use of nature-based solutions (NBS) potentially offers urban areas the opportunity to deliver multiple environmental and socioeconomic benefits. In particular, approaches linked to NBS can limit the degree of climate exposure and vulnerability impacting upon urban infrastructures. The success of NBS in addressing climate change pressures will require an improved understanding of the characteristics of environmental risk and the ability to evaluate alternate adaptive pathways. In response, this chapter explores those components which are central to effective urban infrastructure assessment and considers how they may assist in the formulation of infrastructure strategies.

We stress the need for an approach which is both scenario-focused and fully integrated within existing spatial planning frameworks. Here, we draw specific attention to the utility of strategic environmental assessment (SEA) in both embedding environmental evaluation within mainstream spatial planning and providing the basis for the comparative evaluation of alternatives. We also argue for an approach which recognizes areas of complementary interaction between “gray infrastructure” (whether existing or proposed) and approaches linked to NBS. In order to highlight examples of potential development responses, we draw on best-practice case study examples from the European Union (EU)–funded GROWGREEN project.
