Communities across the world have been transformed through Asset Based Community Development (ABCD), a strength-based approach to change. ABCD builds community from the inside out as residents become producers rather than needy people seeking services. Participants learn the power of asset mapping, a fundamental tool that discovers the gifts of individuals, the power of networks and associations, and local organizations that are then leveraged to create change. ABCD is at the center of a large and growing movement that considers local assets as the primary building blocks of sustainable community development.
