"Excluded from the city's opportunities, physically, politically and economically marginalized, slum dwellers are particularly vulnerable to crime and violence. They face an acute risk of becoming victims or offenders and live in a state of constant insecurity. Only a few cities have incorporated a coherent component to prevent crime and mitigate violence in their urban development agendas. Impact on urban safety has occurred somewhat unexpectedly. That is the main lesson to be drawn from the pages of this book: urban policy integration."--pub. desc.

The Challenge of Slums presents the first global assessment of slums, emphasizing their problems and prospects. Using a newly formulated operational definition of slums, it presents estimates of the number of urban slum dwellers and examines the factors at all level, from local to global, that underlie the formation of slums as well as their social, spatial and economic characteristics and dynamics. It goes on to evaluate the principal policy responses to the slum challenge of the last few decades. From this assessment, the immensity of the challenges that slums pose is clear. Almost 1 billion people live in slums, the majority in the developing world where over 40 per cent of the urban population are slum dwellers. The number is growing and will continue to increase unless there is serious and concerted action by municipal authorities, governments, civil society and the international community. This report points the way forward and identifies the most promising approaches to achieving the United Nations Millennium Declaration targets for improving the lives of slum dwellers by scaling up participatory slum upgrading and poverty reduction programmes. The Global Report on Human Settlements is the most authoritative and up-to-date assessment of conditions and trends in the world's cities. Written in clear language and supported by informative graphics, case studies and extensive statistical data, it will be an essential tool and reference for researchers, academics, planners, public authorities and civil society organizations around the world.

The UN currently estimates that there are about 837 million urban slum dwellers worldwide, and this figure is likely to rise to 1.5 billion by 2020 if current trends are not reversed. This book offers five geographically and institutionally diverse case studies from Latin America, where some of the longest-running and most successful programmes in this field have been conducted. These programmes, involving a wide variety of funding arrangements and agencies, demonstrate the positive impact that community participation and people-oriented service solutions can have on slum upgrading efforts in low income urban areas.

"Slum upgrading programs are being used by national and city governments in many countries to improve the welfare of households living in slum and squatter settlements. These programs typically include a combination of improvements in neighborhood infrastructure, land tenure, and building quality. In this paper, the authors develop a dynamic general equilibrium model to compare the effectiveness of alternative slum upgrading instruments in a second-best setting with distortions in the land and credit markets. They numerically test the model using data from three Brazilian cities and find that the performance of in situ slum upgrading depends on the severity of land and credit market distortions and how complementary policy initiatives are being implemented to correct for these problems. Pre-existing land supply and credit market distortions reduce the benefit-cost ratios across interventions, and change the rank ordering of preferred interventions. In the light of these findings, it appears that partial equilibrium analysis used in typical cost-benefit work overstates the stream of net benefits from upgrading interventions and may in fact propose a misleading sequence of interventions.
