Claudia Wagner-Riddle


INI North America Centre Director


School of Environmental Sciences, University of Guelph, Canada


Alexander Hall, 50 Stone Road East Guelph, Ontario, N1G 2W1 Canada



She specializes in soil science and meteorology. Her early research as a part of the Climate Change Funding Initiative contributed important scientific advances that were integrated into Intergovernmental Panel on Climate Change (IPCC) methodologies for the development of greenhouse gas inventories. Furthermore, her early research on N2O emissions during spring-melt informed the development of Canada’s N2O inventory model and her continued research and expertise in this area continues to directly inform national models of nitrogen transfers and emissions.

Dr. Wagner-Riddle’s direct contribution to ECCC’s inventory development process began in the mid-2000’s through her development of the Canadian National Manure Management Methane Model. Her participation continued with her participation in an Advisory Panel on Agricultural Emissions; a group of experts put in place to provide direction to government to improve the emission quantification methodologies in the Agricultural Sector of the Canadian. This panel provided important direction to ECCC scientists, resulting in improvements in Canada’s agricultural emission inventory program and our ability to estimate GHG emissions from agricultural sources at the national scale.

She is active in both Canadian and American soil science communities and has over 140 journal publications. She is Editor‐in‐Chief of the journal Agriculture and Forest Meteorology, Associate Editor for the Journal of Environmental Quality and the Canadian Journal of Soil Science. She is also Fellow of the American Meteorological Society and the Soil Science Society of America. She has held several national and international projects and is currently leading a national graduate student training program of Climate‐Smart Soils in Canada that involves natural and social scientists from 6 universities and collaborators from 21 organizations spanning the whole value‐chain of food production.
