There are other models that imagine a new economic way. Here are three:

Asset-Based Community Development (ABCD) Institute at DePaul University. Building on the skills of local residents, the power of local associations, and the supportive functions of local institutions, asset-based community development draws upon existing community strengths to build stronger, more sustainable communities for the future. The website includes online resources for training and implementing such an approach and links to pertinent manuals and books.
Luther Snow’s “Financial Strategies for Social Innovation: Doing Well by Doing Good.” Snow’s website includes information about community asset-mapping and collaboration in developing long-term sustainability in a social innovation project.
Partners for Sacred Spaces helps congregations and others with a stake in older religious properties make the most of them as civic assets in ways that benefit people of all faiths and of no faith. It provides programs, resources, and tools to help reimagine a sacred space.
