Community is of course to a degree an open definition and the scale you choose to apply
Large metropolitan areas might have several sub communities if your definition of a community is perhaps only a few square miles or maybe ten thousand people
CSA's, Farmers Markets, Time Banks and other systems are specific to the local scale economy even if some producers may come from the general region and some consumers at Farmers markets may be tourists
Foods grown for volunteer organizations or food banks can be measurable production
Foods that are grown locally but are not measurable within in local marketplace are also part of the system
