The core ideas and methods presented have been widely field-tested in a wide range of urban settings in both developing and urbanized cities. The manual uses case studies to demonstrate methods in action and shows how they can be customized to local needs.It provides a framework for planning participatory projects and building the necessary institutional support. It complements "Growing Up in an Urbanizing World" and derives from the same UNESCO project giving educators, planners and others working with urban children and communities a very valuable tool.
