The Madison Area Community Supported Agriculture (CSA) Coalition works to create a sustainable, just, and locally based food system in Southern Wisconsin by promoting and supporting CSA farms, coordinating community and farmer education programs about the benefits of locally, sustainably grown foods, and operating the Partner Shares Program which raises funds to subsidize CSA memberships for households on a limited income.

CSA is a unique social and economic arrangement between local households and farmers who work together to share the responsibility of producing and delivering fresh food.  Households support the farm by paying an annual fee in the winter or spring that entitles them to a "share" of the season's harvest.  Once harvesting begins, members pick-up a weekly box of fresh foods which may include produce, fruits, cheeses, eggs, meats, poultry, flowers, herbs or preserves.
