This case book was prepared by an independent task force on 'community action for social development' as a prelude to the Copenhagen Social Summit. The 12 case studies on successful community-based social development are from a wide range of countries, such as Zimbabwe, Colombia, Tanzania, Sweden, India, Kenya, Poland, Pakistan, Tibet, Thailand and China. This casebook presents diversity of the worldwide movement towards community- based social development and defines a common process used by the successful programs. A common theme that runs through these case studies is that sustainable social development is difficult but possible; outside agencies involved in sustainable human development should respect people, their values and cultures, build trust and share power and responsibility with the people. The book also stresses the need to provide space for community action and maintain close co-operation between the state, community and NGO.
