ABSTRACT

As metrópoles brasileiras estão passando por grandes transformações. As periferias se converteram em situações críticas, onde conflitam diferentes políticas públicas, assentamentos de moradia precária e sistemas ambientais desconfigurados. As várzeas dos rios, como o Tietê na zona leste de São Paulo, são paradigmáticas das condições de não equilíbrio, exigindo repensar os fenômenos extremos que afetam a paisagem urbana: as chuvas torrenciais, as inundações; desenvolver estratégias sociais e instrumentos técnicos para lidar com as instabilidades; recolocar as relações entre o rio e a cidade, integrando os dispositivos de contenção de enchentes e o meio ambiente, em outras bases conceituais e operacionais.(AU)


The Brazilian metropolises are undergoing great transformations. The peripheries have become critical situations, where different public policies, settlements of precarious housing units and disaggregated environmental systems conflict. River floodplains, such as that of the Tietê river in eastern São Paulo, are paradigmatic of a condition of non-equilibrium, requiring a new perspective on the extreme phenomena that affect the urban landscape: torrential rains, floods. It is necessary to develop social strategies and technical tools to deal with climatic instabilities and to re-evaluate the relations between the river and the city, integrating flood containment devices and the environment into other conceptual and operational foundations.(AU)
