The report provides evidence that rising land prices has forced the urban poor out of inner-city informal musseques to occupy lower-valued environmentally risky sites such as river basins, dangerous slopes and areas susceptible to flooding on the margins of cities like Luanda. The urban areas of Luanda (the capital city of Angola), Huambo (the capital of Huambo Province), and Cachiungo (the main town in the District of Cachiungo in Huambo Province) were chosen for this study as they are dissimilar and were considered to be representative of different types of urban areas in Angola. DW carried out the research project from 2009 to 2011 to examine the differences in the three urban areas. The study used field research and new mapping techniques to supply baseline data on the five indicators which the United Nations uses to define slums for the Millennium Development Goals (MDGs) and, secondly, to explore in more depth the spatial aspects of poverty and urban environmental issues in Luanda.
