My research employs ordinary commodities to reveal the social and environmental impact of modern agriculture. My latest project examines the history of biomass energy in rural Canada, and I have also written about sodbusting and soil treatment on Canadian farms.
For ongoing updates on the work I do as Canada Research Chair at UPEI, see the website of the GeoREACH Lab (Geospatial Research in Atlantic Canadian History)
See also the work I do on agricultural commodities and energy, including:
- Flax
- Firewood
- Fertilizer
- The Sustainable Farm Systems project

Dear Dr. MacFadyen,
I recently saw a comment that you posted 5 years ago on NiCHE indicating that you were working on a project to quantify total caloric outputs from Maritime ecosystems.
I would very much love to read this work, if you happened to publish your findings!
Thank you for all your contributions to research and practice!
Respectfully,
Jillian Ruhl
