In this book, we want to integrate two of the major topics being discussed today in urban policy: sustainability and partnerships. While each of these two concepts is quite distinct there is a congeniality between them that we find intriguing and worthy of our study. Sustainability is an objective, and partnerships are a mechanism. We want to put the mechanism in service of the objective. Any sustainability initiative is a collective or collaborative effort, involving a city’s public administration, of course, but to be successful it must involve and engage the imagination and energies of many individuals from many social, cultural, business, university, neighborhood, religious and other communities. Knowing how partnerships are formed and work, how the interest of participants is maintained, and how the energies, talents and knowledge of diverse individuals can be effectively utilized toward a common objective, is necessary if success is to be achieved.
