Various kinds of informal and extra-legal settlements—commonly called shantytowns, favelas, or barrios—are the prevailing type of urban land use in much of the developing world. United Nations estimates suggest that there are close to 900 million people living in squatter communities worldwide, with the number expected to increase in the coming decades.

Informal Urbanization in Latin America investigates prevailing strategies for addressing informal settlements, which started to shift away from large-scale slum clearance to on-site upgrading in Latin America over the last 40 years, by improving public spaces, infrastructure and facilities. The cases in this book range from one micro intervention (the Villa Tranquila Project in Buenos Aires) to three large-scale government-run projects: the celebrated Favela Bairro Program in Rio de Janeiro, the social housing program in São Paulo and the famous Proyectos Urbanos Integrales Approach in Medellín. The cases show a collaborative and sensitive transformation of landscape and public space, and provide designers and planners with the tools to develop better strategies that can mitigate the volatility that the residents of non-formal neighborhoods are exposed to. The book is a must-read for all who are interested or working in the global urbanization as well as social equity.
