The local food movement arose in response to overarching political support for large-scale commercial agriculture at the federal and state levels, which still dominates the national food system. Beyond this, particular challenges for institutionalizing innovative food initiatives for low-income residents include a lack of sustained funding, zoning restrictions, insufficient training and institutional support, as well as locating and converting productive land in urban and suburban areas. Thus, despite the positive impact of local food systems, 14.9 % of U.S. households were still food insecure in 2011.
