Community-supported agriculture (CSA; sometimes known as community-shared agriculture) is an alternative, locally based economic model of agriculture and food distribution. A CSA also refers to a particular network, or association of individuals, who have pledged to support one or more local farms, with growers and consumers sharing the risks and benefits of food production.
CSA members, or subscribers, pay at the onset of the growing season for a share of the anticipated harvest; once harvesting begins, they periodically receive shares of produce. In addition to produce, some CSA services may include additional farm products like honey, eggs, dairy, fruit, flowers and meat. Some CSAs provide for contributions of labor in lieu of a portion of subscription costs.
The term CSA is mostly used in the U.S. and Canada, but a variety of similar production and economic sub-systems are in use worldwide.
The term "community-supported agriculture" was coined in the northeastern United States in the 1980s, influenced by European biodynamic agriculture ideas formulated by Rudolf Steiner. Two European farmers, Jan Vander Tuin from Switzerland and Trauger Groh from Germany, brought European biodynamic farming ideas to the United States in the mid-1980s. Vander Tuin had co-founded a community-supported agricultural project named Topinambur located near Zurich, Switzerland. Coinage of the term "community-supported agriculture" stems from Vander Tuin. This influence led to the separate and simultaneous creation of two CSAs in 1986. The CSA Garden at Great Barrington was created in Massachusetts by Jan Vander Tuin, Susan Witt, and Robyn Van En. The Temple-Wilton Community Farm was created in New Hampshire by Anthony Graham, Trauger Groh, and Lincoln Geiger.
