Community-University-Funder Alliance for Community Well-being: A Community Partnership to Build Sector Power and Capacity for Social Impact. We propose the development of a sustainable Community Alliance for building third sector power and capacity. While building the capacity of individual organizations is important, we believe that a strong third sector working together is needed to advance community well-being on a larger scale. We want to foster the type of connectivity that helps foster an environment in which organizations act beyond their own borders; a precondition for more sweeping sector-level change. We believe in the power of network building, and that building social capital among organizations in the sector - creating the conditions for innovative and collaborative activity-is potentially a powerful approach to sector capacity-building and social change.
