The Principle of Co-operation among Co-ops speaks to the advantages for co-ops and their members working together through formal regional, national, and international co-operative structures. The Neighboring Food Co-op Association (NFCA), a federation of 35 food co-ops and start-ups across New England, grew out of dialog among food co-ops on what we could accomplish by working together. This presentation provides an in-depth look at NFCA structure and successes, future vision, and provides insights on how food co-ops can work together regionally to support shared success and collaboration at all levels, growing the co-operative economy together.
