Models Show Some U.S. Metro Areas Could Feed Themselves Locally

A modeling study by Tufts University, published in Environmental Science & Technology, found that some but not all U.S. metro areas could grow all the food they need within 155 miles. The study considered 378 metropolitan areas across the country, and found that metro centers in the Northwest and interior of the country have the greatest potential for localization. Although large portions of the population along the Eastern Seaboard and the southwest corner of the U.S. could not meet demand locally, other cities are surrounded by ample land to support local and regional food systems, researchers say.
