Claudia Wagner-Riddle

Professor, School of Environmental Sciences (SES)
University of Guelph

Dr. Claudia Wagner-Riddle is a Professor in the School of Environmental Sciences (SES), University of Guelph, Canada. Originally from Brazil, Claudia has degrees from the University of Sao Paulo and Guelph. Claudia leads an internationally-renowned research program utilizing the measurement of greenhouse gas emissions to determine the carbon footprint of food, feed, and fuel produced by agriculture. Claudia currently leads several projects focused on evaluating how soil health impacts ecosystem services, including a new $2 million infrastructure using large scale soil weighing lysimeter. Claudia is a fellow of the Soil Science Society of America, the American Meteorological Society and of the Canadian Society of Agricultural and Forest Meteorology. She is the Editor-in-Chief of the international journal Agricultural and Forest Meteorology and leads a nation-wide training program on Climate-Smart Soils. Claudia was recently appointed Director of the North American regional chapter of the International Nitrogen Initiative and was awarded the 2020 IFA Borlaug Award of Excellence in Crop Nutrition. Wagner-Riddle has published >160 papers and has an h-index of 43 (Google Scholar).

Managing cropping systems for reduced greenhouse gas emissions and increased carbon sequestration

Cropping systems contribute significantly to greenhouse gas (GHG) emissions through farm-scale carbon dioxide (CO2) and nitrous oxide (N2O) emissions, while also storing carbon in soils. These emissions can be managed for long-term sustainability of the agricultural sector and contributing solutions to climate change though the use of climate-smart soil practices. An overview of mitigation practices focused on nitrogen fertilizer (4R practices), manure, tillage and crop management will be presented. Integrated assessments of practices considering economic aspects will be presented as case studies.
