“…First, writers aligning themselves with the 'postmodern' or 'cultural' turn in human geography are addressing nature-society relations in ways that interrogate sustainability discourses and projects. 17 There is a substantial and growing literature reviewing geographical and related work on diverse representations of the concept of nature, its social construction and the theoretical and political implications of culturally filtered understandings of nature (Castree, 1995;Demeritt, 1994;Gandy, 1996;Olwig, 1996;Gerber, 1997;Castree and Braun, 1998;Mathewson, 1998). At the risk of oversimplifying, the central focus of much of this work is on how ideas of nature are constantly reformulated, signified and used by different social agents to, on one hand, bolster claims of knowledge and power over other agents and attendant ecosystems or, on the other, defend access to and control over resources in the face of others' knowledge and power claims.…”
