Local food
Local food or the local food movement is 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 for health, environmental, community, or social impact in a particular place. The term has also been extended to include not only 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 the 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
