That's right! Somerville Food and Nutrition Services joined a CSA . A few weeks ago we piloted a Farm Fresh Salad Bar partnership with Drumlin Farm, Lincoln, MA . What is a CSA? CSA stands for Community Supported Agriculture. According to the USDA , CSA philosophically refers to a "community of individuals who pledge support to a farm operation so that the farmland becomes...the community's farm, with the growers and consumers providing mutual support and sharing the risks and benefits of food production." It can also imply an economic relationship between farmer and consumer, often called subscription farming. In other words, a subscriber agrees to buy a minimum amount of produce at a fixed price, often paying in advance for the subscription. While we haven't paid in advance, we have committed to buying a minimum of 3 and a maximum of 5 shares (or veggie boxes) each week. This commitment creates a guaranteed market for the farm's produce.
