Expertise, truth, and urban policy mobilities: global circuits of knowledge in the development of Vancouver, Canada's 'four pillar' drug strategy

摘要

There is growing attention across the social sciences to the mobility of people, products, and knowledge. This entails attempts to extend and/or rework existing understandings of global interconnections and is reflected in ongoing work on policy transfer-the process by which policy models are learned from one setting and deployed in others. This paper uses a case study of the development of an innovative approach to drug policy in Vancouver, British Columbia to deepen our understanding of what I call 'urban policy mobilities.' It details the often apparently mundane practices through which Vancouver's 'four-pillar' drug strategy-which combines prevention, treat-ment, enforcement, and harm reduction-was learned from cities outside North America and is now increasingly taught elsewhere. In doing so it draws on a neo-Foucauldian governmentality approach to emphasize the role of expertise (specialized knowledge held by many actors, not just credentialed professionals) and the deployment of certain powerful truths in the development of the policy. The paper concludes by discussing the spatialities of urban policy mobilities and raising questions about the political and conceptual importance of also maintaining a focus on the causes and consequences of policy immobilities.
