Food systems generally include growing, processing, distributing, retailing, preparing, eating, and the disposal of food waste. A 2010 USDA study of local food systems found that local markets account for a small but growing share of total U.S. agricultural sales. Over the decade of 1997 to 2007, direct-to-consumer sales rose from $551 million to $1.2 billion. The number of farmers’ markets grew 92 percent from 1998 to 2009. Farm-to-school programs quintupled from 400 in 2004 to 2,095 in 2009. Other federal, state, and local government programs increasingly support local and regional food systems.
