CSA is the abbreviation for Community Supported Agriculture, a system in which consumers fund local farms by paying in advance for agricultural products. This model reduces the financial risks for the farmer(s) involved because the costs of seeds and of planting/tending crops are covered in advance by consumers. Throughout the growing season, CSA members receive a portion of the farm's harvest each week. Members share the financial risks and the bounty of the harvest: if it is a successful growing season, members receive a lot of food; if there are fewer crops, they receive less. Members are also encouraged to visit the farm(s) and some even volunteer there.
