The U.S. Department of Agriculture (USDA) defines a food desert as a low-income community in which the nearest supermarket is at least one mile away from a populated zone. This infers that zones deemed “food deserts” would have limited access to healthy foods without the burden of inherent hardships, such as ownership of car or access to public transportation to reach the nearest supermarket.
One fiscal argument for augmenting local food networks is to reduce the tremendous costs that fuel and labor add to shipping produce from distant sites, whether in urban areas like Detroit or rural regions of the country such as Alaska. “In some of our isolated villages in Alaska, families are having to choose between the price of heating oil and food,” reported Dave Monture, technical assistance specialist for the Intertribal Agriculture Council. He said the cost of milk in some areas has risen to $20 a gallon.
