JARDINS DE CHUVA EM ROTATÓRIAS: uma solução sustentável inovadora para a gestão de águas pluviais
Year: 2026
Type: article
Abstract: Uncontrolled urban growth has increased soil impermeability and floodplain occupation, making urban drainage insufficient and worsening flooding. Climate change is exacerbating this problem, requiring sustainable solutions such as Nature-based Solutions (NbS). Rain gardens, one of these NbS, help capture, retain, and infiltrate rainwater, reducing runoff and improving air and water quality. However, their implementation faces challenges such as lack of space, population resistance, and topographical difficulties. The research proposes using roundabouts to install rain gardens, taking advantage of their underutilized areas, low slope, and strategic position for water collection. The study analyzed the Uberabinha stream sub-basin in São Paulo and identified 25 roundabouts with a storage capacity of 255.03 m³ of water. Although the impact on overall drainage is modest, the proposal promotes natural processes and reinforces the connection between the city and nature. Pilot implementation in different urban contexts and integration of NBS are recommended to enhance environmental, social and economic benefits.
