Department of Regenerative Organic Agriculture


About us

The Department of Regenerative Organic Agriculture explores the leading edge of regenerative organic agriculture principles and practices — key to improving soil health, human health, and climate health. Our curriculum emphasizes training in organic agriculture as defined by governments worldwide. Our regenerative agriculture programs build an understanding of how to think critically and holistically when considering the design and flourishing of organic agriculture systems. We engage students in the process of learning through hands-on projects, problem-solving, question-building, journaling, researching, teaching, and collaborating.

Regenerative Agriculture is a systems-based approach to agriculture that leverages natural ecology to build soil, improve water efficiency, and increase biodiversity while emphasizing healthy food, feed, and fiber systems as the foundation of a strong community. Regenerative Agriculture, as defined by Nature, “Aims at regenerating, renewing, and further improving the soil functions and capabilities for ecosystem services in an always-improving process.” Regenerative agriculture practices capture and store more carbon in the soil and release fewer greenhouse gases than conventional agriculture. And by using regenerative principles, we can revitalize soil biodiversity to enhance ecosystem services — resulting in carbon drawdown and the restoration of the water cycle.
