Green Infrastructure, Grey Epistemologies, and the Urban Political Ecology of Pittsburgh's Water Governance

摘要

This paper explores Pittsburgh's water governance to consider the way divergent approaches to urban stormwater management reproduce existing urban metabolisms and belie more radical possibilities for the urban hydro-social cycle. Federal action has forced municipalities in the Pittsburgh metropolitan region to make changes to its urban water systems and develop a plan to comply with water quality regulations. Within Pittsburgh's water governance debates, compliance centers on various sets of technological strategies for defining and solving purportedly wicked urban environmental problems. Urban political ecology, here, is used to deconstruct the tensions and convergences between these different stormwater governance strategies. I argue that green infrastructure approaches (whose intentions are to expand practice and participation) are framed by dominant grey epistemological approaches. In this view, alternative and creative forms of greening the city may not necessarily represent a more democratic process, but instead reproduce uneven urban landscapes under greener cover.
