正文(英文) | Also available in Español As is the case in many capitals in Latin America and around the world, the City of Buenos Aires used every square meter to house the growing number of people. In this process the many natural streams draining the area were invaded. Flood plains were used to construct buildings. Streams were replaced by canals and tunnels, limiting the natural connection between surface and groundwater bodies. Water bodies were used to dispose of litter and sewage and the water was seen as a nuisance. This has led to a number of challenges now exacerbated by climate change and the city is struck more often by serious flooding causing damage to assets and paralyzing urban transport with strong impact on the more vulnerable people. In recent years, the city started to adopt nature-based solutions, with support from the World Bank. With Green Infrastructure the city intends to bring back the value added of water and optimize the co-benefits is relation to recreation, mitigation of heat islands and value creation. Floods in the city have shown to cause not only asset damages but it paralyzes transport across the city, generating important negative impact on economic activities. People are not able to get to their jobs affecting in particular the more vulnerable depending on their daily income and do not have the economic resilience to cope with salary loss nor property damage. The Flood Risk Management Support Project for the City of Buenos Aires supports a series of structural and non-structural measures within the City. The Bank financed Project is the continuation of a collaboration story with the City of Buenos Aires that started in 2006, with the development of a Hydraulic Masterplan. Structural measures include large gray infrastructure to increase drainage capacity towards the Rio de la Plata. Additionally, As a result of the initial pilots, the city is adopting an improved planning process, and profits from the multiple co-benefits generated by these interventions. Aside from increased retention capacity these interventions provide space to recreate and complement the urban ecological corridors. Additionally,
