    Sammanfattning : This dissertation critically examines the tension between mainstream and counterpoint perspectives on sustainability on the basis of analyses of four approaches to this issue: environmental economics, ecological economics, adaptive management, and bioregionalism, which are presented as successive attempts to challenge mainstream, modernist perspectives on socio-ecological relationships. The different worldviews and identity constructions associated with the two extremes in this spectrum of approaches are examined on the basis of interviews with environmental economists and bioregionalists in California.
