Werthmann, Christian: Informal Urbanization in Latin America: Collaborative Transformations of Public Spaces, 2021

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. Forty years ago, prevailing strategies for addressing nonformal settlements started to shift away from large-scale slum clearance to on-site upgrading in Latin America. Many of these historic initiatives tried to recover informal neighborhoods by improving its public spaces, infrastructure and facilities. But was progress really achieved? For whom? For how long? And how? The author investigated upgrading attempts in four major cities of Latin America. The cases range from one micro intervention (the Villa Tranquila Project in Buenos Aires) to three large-scale government run projects like 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. By observing the projects over a period of ten years an overall picture of struggle, gains and setbacks emerges. While a collaborative and sensitive transformation of landscape and publicspace has the potential to contribute to improvement (better infrastructure, environmental risk reduction, economic opportunities, community cohesion, civic self-esteem and democratization), a change in political attitude or in global drug trade can threaten or obliterate the gains. It becomes clear: designers and planners have to develop better strategies that can mitigate the volatility that the residents of non-formal neighborhoods are exposed to.
