About Nathan Pelletier
I'm an Associate Professor, jointly appointed in the Faculties of Science (Biology) and Management at the University of British Columbia - Okanagan. I currently hold the NSERC/Egg Farmers of Canada Industrial Research Chair in Sustainability.
My work is broadly situated in the fields of ecological economics and industrial ecology, emergent research areas focused on understanding and managing the sustainability dimensions of economic activity. My research vision is motivated by the recognition that promoting human well-being and social justice ultimately requires first that we maintain the integrity of the natural communities that provide the context in which human life and society become possible and upon which we depend for our basic needs.
Areas of research interest are the theory and practical application of ecological economic instruments in bio-economy (food, feed, and biomass) sustainability measurement, management and communication initiatives. I contribute to the development of methodological frameworks for evaluation and management of the scale, resource efficiency, and social dimensions of sustainability - in particular, life cycle-based product and organization-level accountancy tools for supply chain sustainability management. I subsequently apply these frameworks to scenario-model the sustainability implications of alternative bio-economy technologies and management regimes with respect to sustainability targets and thresholds. Specific domains of interest include climate change, energy use, reactive nitrogen, food security, social license, and market access.
