Brownfields in São Paulo city

Abstract

Brownfields are a reality in the metropolis. Areas that have been contaminated by industrial activities, irregular waste deposits or toxic substances, are difficult to follow the changes in land use and occupation, familiar in the dynamics of society. Understanding the relationship between population shifts and use e occupation of urban land can help policymakers and planners ensure that cities remain economically productive and environmentally sustainable. Brownfields revitalization is an issue that has an essential role in The Sustainable Development Goal, as goal Sustainable Cities, and Communities. In this research, five districts on São Paulo city were chosen to analyse the contaminated areas and identify the percentage of revitalization e clean-up also considering the price of urban land and the number of the population residing in these districts. The results indicated that the process of revitalization and clean-up of contaminated land is happening in all five districts evaluated, in Santo Amaro the process is more evident. It is the same place where the price of the square meter is the most expensive and had the highest percentage of contaminated areas with confirmed risk. However, this revitalization process is different, given the essential factors of each district, as localization and zoning law. This difference means different answers on general public strategies to the revitalization of brownfields. So local studies can offer more instruments to policymakers.
