Most of the American Midwest was once a vast savanna, an open grassland with abundant trees and wildlife. As the land was converted to agriculture many of the trees were lost, and with them went countless benefits to the landscape, to air and water, soil health, and wildlife. The practice of agroforestry allows farmers to return those benefits to their land –– and provides profit opportunities and increased carbon sequestration. We talk to Keefe Keeley, executive director of the Savanna Institute about how farmers can get started using trees to their advantage.
