What is it:
“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 receive weekly shares of vegetables and fruit, in a vegetable box scheme.
Often, CSAs also include herbs, honey, eggs, dairy products and meat, in addition to conventional produce offerings. In theory a CSA can provide any product to its members, although the majority of CSA operations tend to provide produce, fruits, and various edibles.”
Relevancy:
CSA shows a different way of organizing to secure a local food supply. It seems similar to the Danish “Fødevarefællesskaber”
