This book addresses the urgent need for adequate shelter and services for the urban poor in developing countries. It not only examines the evolution and performance of policies and projects, but also analyzes factors which effect policy implementation, and identifies alternative approaches for upgrading settlements as well as increasing access of the poor to these shelters. To enhance the practicality of this excellent source, there are ten original case studies of urban projects, eighteen country papers, and concept papers from the United Nations Centre for Regional Development.
