Farming has been an institution in Concord and Carlisle for centuries. As early as 1775, Concord was a busy hub of trade partly because of its access to Boston but also given the topography of land and climate agreeable to farming. This tradition continues today, with approximately 812 acres of working farmland between the two towns. Community supported agriculture (CSA) is an integral part of these farms, ensuring the farmers a sustainable source of funding and providing residents with fresh, healthy produce spring through fall. In a CSA, residents purchase a ‘subscription’ for produce or other farm products that can then be picked up as they are harvested. CSAs are very popular in the Concord area and tend to sell out quickly.
