The pilot urban farm was constructed at Mitchell Elementary School."The goal of the farm-to-school initiative is to increase the availability of and access to healthful, local foods as well as to stimulate the local economy," Farm-to-School Director Olivia Thompson said. "Buying and eating local foods builds a strong local economy and preserves personal and community health. Farm-to-school programs create a market for area farmers and make it possible for children to have consistent access to nutrient-packed foods such as locally grown fruits and vegetables."
