Agriculture in the Boreal Forest: Exploring Soil Carbon, Fertility, and Land Use Change to Support Sustainable Northern Food Systems
The traditional food system of many northern communities is currently being challenged by the increasing prevalence of natural disturbances brought on by disproportionate climatic warming. To alleviate resulting issues of food insecurity, northern communities are incorporating agriculture as a suppl...
