Making 'green' fit in a 'grey' accounting system: The institutional knowledge system challenges of valuing urban nature as infrastructural assets

摘要

Nature is increasingly enrolled as a functional component of infrastructure in cities as municipal governments attempt to cost-effectively replace and repair deteriorating engineered infrastructures. Green infrastructure (GI) is a popular incarnation of this enrollment, most often defined in the United States (US) as the use of vegetated land (e.g. street-trees, bioswales, parks) to provide stormwater management services. However, GI is far from mainstream. While many municipalities cite technical performance uncertainty as a primary reason for this lag, institutional challenges of knowledge system integration also create road-blocks to GI management.
