A sustainable urban future for all requires raising the quality of life of the most vulnerable. The research presented in this book attempts to show how this potential can be harnessed, by showcasing sustainable solutions developed by the urban poor themselves. The book’s case studies were conducted in the growing urban and peri-urban areas of Peru, Senegal, Bangladesh, Ethiopia, the Philippines, Thailand, and the Democratic Republic of Congo. They outline concrete strategies for sustainable urban living and design, developed in partnership with low-income city dwellers. The book offers insights into both theory and practice, which will be useful and inspiring to students, researchers, development practitioners, and policymakers alike.
