But it is gaining momentum with many growers and the customers they serve. What is it, though? “To define ‘regenerative’ simplistically, it is a series of farming techniques that leave the soil and water and animals in a better space than when you found them,” Andrew Gunther explains. Gunther is executive director of A Greener World. The Oregon-based nonprofit is piloting a new Certified Regenerative farming program with 50 farms.
