“…In contrast to "hybrid" perspectives, an ontological and conceptual separation of the social and nonhuman biophysical worlds is retained. Examples of such scholarship include Norgaard's (1984) concept of coevolution, Bunker's (1985Bunker's ( , 2003 and Bunker and Ciccantell's (1999) materio-spatial world systems/new historical materialist approach, Nauser and Steiner's (1993) human ecology, Crumley's (1994) historical ecology, Woodgate and Redclift's (1998) coevolution/social construction framework, Escobar's (1999) antiessentialist political ecology, Forsyth's (2001Forsyth's ( , 2003 and Forsyth and Evans' (2013) critical realist political ecology, Prew's (2003) notion of world-ecosystem, and Carolan's (2005) ecologically embedded sociology (regarding the nature-human dualism underpinning some of these works, see Ivakhiv 2002). Much of the postpositivist traditions in environmental subfields of the social sciences, e.g., ecological/environmental economics, and interdisciplinary fields, such as sustainability science, landchange sciences, global-change sciences, natural-hazards research, and vulnerability studies, can also be said to generally adopt an integrative approach (e.g., Burton et al 1978, Ostrom 1990, Blaikie et al 1994, Turner et al 2003, Sen 2004, Clark 2007, Dasgupta 2010, Kates 2011, Levin et al 2013).…”
