Sara Nelson is a doctoral candidate in the Department of Geography, Environment and Society at the University of Minnesota-Twin Cities, where her dissertation combines critical political economy, science studies, and ecology to explore how and why scientists, policymakers, and private investors are working to make ecosystems function as natural capital. Through archival research, interviews, and ethnographic research, she seeks to understand how and why ecosystems have come to be understood as providers of “services”—such as flood mitigation, carbon sequestration, or even aesthetic pleasure—and how investment in ecosystem services is becoming a corporate strategy. How is the emerging ecosystem service economy being built, and how is the value of nature being negotiated and redefined through ecosystem services-based research and policy? What types of labor underpin the ecosystem service economy? What are the implications for environmental politics as ecosystems are reinvented (discursively and materially) as “resilient” infrastructure for climate change adaptation? Sara has participated in recent conferences and workshops, including: the Society for 21st Century Studies conference, “Anthropocene Feminism,” University of Wisconsin-Milwaukee, April 10–12, 2014, where she presented the paper “The labor of social-ecological reproduction: consolidating the ecosystem service economy”; “Dimensions of Political Ecology” conference, University of Kentucky-Lexington, February 27 to March 1, 2014, at which she took part in the session “Breaking Ground in Political Ecology”; the Annual Meeting of the Association of American Geographers, Los Angeles, April 9–13, 2013—she was a discussant on the session “Re-evaluating the Anthropocene, Resituating Anthropos: Politics of the Anthropocene II” and co-organized with Garnet Kindervater the panel “Resilience and Critical Practice”; the Society for Literature, Science and the Arts workshop on the theme “Postnatural,” Notre Dame, Indiana, October 3–5, 2013, where she presented the paper “Service ecologies: rent and finance beyond the knowledge economy”; and Annual Meeting of the Association of American Geographers, New York, February 24–28, 2012, with the paper “Adapting to climate change: from resilience to ‘transformability’.”
