Mapping informal settlements: an experience in São Paulo (Brazil)

Abstract

Informal settlements pose great challenges to urban planners, as very often the data available on those locations is insufficient to inform planning decisions. For instance, demographic estimates are often approximate at best, what makes it difficult to dimension the basic services to be provided. At the same time, there is a less material, political perspective behind these extra-legal, self-help processes of housing construction, for it is not only houses that are being auto-constructed in this process, but the very citizenship of those engaged in it: by actively participating to the production of the urban space, those individuals aim to legitimize their claims to be effectively integrated to the “formal” city. The questions raised above seem to be connected to one general issue: the invisibility of a large proportion of the urban population that cannot be found in any official record or in any official map. In order to address this invisibility issue, I present a mapping solution that has been developed over the past years in collaboration with the NGO Teto-Brasil, which proposes, precisely, to bring visibility to the most vulnerable populations in urban areas.

Urban area
An urban area, built-up area or urban agglomeration is a human settlement with a high population-density and an infrastructure of built environment. This is the core of a metropolitan statistical area in the United States, if it contains a population of more than 50,000. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment.
Urban planning
Urban planning, also known as town planning, city planning, regional planning, or rural planning, is a technical and political process that is focused on the development and design of land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks and their accessibility.
Urban sprawl
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development.
