Food produced, processed, and sold within a limited geographical area, and the movement encouraging consumers to buy it. Supporters argue that local food reduces the environmental cost of long-distance transport, keeps money circulating in the regional economy, preserves farmland and food traditions, and offers fresher produce with transparent provenance. Farmers’ markets, farm shops, box schemes, and community-supported agriculture are its main channels. Critics note that transport is only one part of food’s carbon footprint, and that efficient large-scale production can sometimes have lower overall impacts. Definitions of local vary, from a few miles to within a country, and labelling claims are not always regulated.
