Ecologies of actor-networks and (non)social labor within the urban political economies of nature

On September 16th, 2005 the United States began restricting the entry of commodities shipped from abroad in wood packaging materials that do not conform to phytosanitation measures meant to prevent the spread of pests and pathogens. This action results from expensive lessons learned as global commerce facilitates pandemics like Dutch elm disease. Marxist political ecology is well suited to investigate such scenarios with its emphasis on the social production of nature within accumulation regimes. Some scholars contend, however, that Marxist accounts of the contradictions that result from nature's commodification relegate nonhuman organisms to an apolitical role in environmental transformation while reinforcing the nature/society dichotomy. Often viewed as antithetical to Marxism, actor-network theory or ANT emphasizes the ability of actants (both human and nonhuman) to enroll other actants into heterogeneous assemblages or networks. Thus, it is claimed that nonhuman organisms can be attributed ontological status in processes of environmental change, much like their human counterparts. Despite this apparent theoretical discord, political ecologists are increasingly integrating aspects of both Marx and ANT into their analyses. But a more explicit articulation of the ontological basis and epistemic import of theoretical synthesis is warranted. This paper therefore prioritizes and links the ontological status of labor in both of these theories in order to expand the definition of urban environmental politics to include the role of nonhuman organisms. By demonstrating the laboring capacity of Dutch elm disease within the networks of urban political economy, the epistemology of environmental politics is thus expanded. (c) 2007 Elsevier Ltd.
