"Local food", "local food movement" or "locavores" are a movement which aims to connect food producers and food consumers in the same geographic region, in order to develop more self-reliant and resilient food networks; improve local economies; or to have an impact on the health, environment, community, or society of a particular place. The term has also been extended to include not only the geographic location of supplier and consumer but can also be "defined in terms of social and supply chain characteristics." For example, local food initiatives often promote sustainable and organic farming practices, although these are not explicitly related to the geographic proximity of producer and consumer.
Local food represents an alternative to the global food model, a model which often sees food travelling long distances before it reaches the consumer. A local food network involves relationships between food producers, distributors, retailers, and consumers in a particular place, where they work together to increase food security and ensure economic, ecological and social sustainability of a community.
The local food movement began with the creation of the Agricultural Adjustment Act (AAA) of 1933, which spawned today's controversial agricultural subsidies and price supports. The contemporary American movement associated with the term can be traced back to proposed resolutions to the Society for Nutrition Education's 1981 guidelines. These largely unsuccessful resolutions encouraged increased local production to slow farmland loss. The program described "sustainable diets" - a term then new to the American public. At the time, the resolutions were met with strong criticism from pro-business institutions, but have had a strong resurgence of backing since 2000.
In 2008, revisions were made to the United States Farm Bill which put an emphasis on nutrition: "it provides low-income seniors with vouchers for use at local produce markets, and it added more than $1 billion to the fresh fruit and vegetable program, which serves healthy snacks to 3 million low-income children in schools".
No single definition of "local" or "local food systems" exists. The geographic distances between production and consumption varies within the movement. However, the general public recognizes that "local" describes the marketing arrangement (e.g. farmers selling directly to consumers at regional farmers' markets or to schools). There are "a number of different definitions for local [that] have been used or recorded by researchers assessing local food systems [and] most [are] informed by political or geographic boundaries. Among the more widely circulated and popular defining parameters is the concept of food miles, which has been suggested for policy recommendations." The Food, Conservation, and Energy Act of 2008 includes a definition, with "locally" and "regionally" grouped together and defined as:
