Senior Scientist, Climate-Smart Agriculture
Alison provides scientific expertise to the sustainable agriculture team’s efforts to eliminate nutrient pollution from productive agriculture. Her research includes synthesis and meta-analysis of field experimental data in nutrient cycling, with a focus on nitrogen. She works closely with other scientists to better understand how farm management practices can reduce nutrient losses and maintain productivity while also improving water, air, and soil quality. She provides technical expertise to move these efforts from theory and research farms to application in environmental markets and supply chain sustainability commitments.
Prior to joining EDF, Alison worked as a research associate for the Nicholas Institute for Environmental Policy Solutions at Duke University. At the intersection of agronomic sciences and economics, she began synthesizing and modeling the environmental impacts of improved agricultural management for application in policy or private markets. Alison was raised on a farm in Alberta, Canada, where she gained an early interest in agriculture, “learning to do by doing” (4H). In the search for a good dataset, she has collected soil, plant, and other samples in rice fields and on dairy farms; conducted lab tests; surveyed farmers; and scoured the literature for experimental results.
Alison is a member of the American Society of Agronomy, the Soil Science Society of America, and the Canadian Agricultural Economics Society.
Alison received her PhD from Wageningen University in 2009 (Agricultural Economics and Rural Policy), for which her research focused on agricultural land use and externalities. She holds a MS degree (International Agricultural Development, Soil Science) from the University of California-Davis, and a BSc degree (Agricultural Sciences) from the University of Alberta.
