Flagstaff, AZ – Arizona sits in the most arid region in the U.S. But it produces a surprising amount of food, from ancient crops like beans and corn, to winter vegetables that show up on dinner tables around the country. A new report, though, shows some cracks in the southwest's food systems. Former NAU and current U of A researcher Gary Nabhan edited the study, called the "State of Southwestern Food Sheds." He told KNAU's Daniel Kraker that Arizona's food security has never been more vulnerable.
