Agroecology

Despite producing an unprecedented quantity of food worldwide, industrial agricultural systems also exacerbate biodiversity loss, soil and water degradation, and climate change. University of Michigan experts are examining the nexus between modern food systems and greenhouse gas emissions, and identifying more sustainable production approaches based on agroecology. Key to this work are researchers at the Sustainable Food Systems Initiative and the Center for Sustainable Systems who are advancing the scientific basis for sustainable and resilient food systems.
