Estratégias de adaptação e mitigação aos impactos decorrentes da mudança do clima no bairro COHAB, Recife - PE

Abstract

The challenges faced by Brazilian coastal metropolitan regions in preparing for future climate hazard scenarios are already evident in statistics on the state of these metropolises. Climate change poses a growing threat to urban areas, intensifying extreme weather events such as heavy rainfall and heat waves. Urban risk environments are preferentially linked to geomorphological occurrences related to hydrological events, the absence of natural habitats, and extensive urbanization. These phenomena especially affect neighborhoods located on hills and slopes, where housing often faces high risks. This study is based on a comprehensive review of the literature on climate change, its urban impacts and available adaptation and mitigation strategies. In addition, risk areas for landslides and floods caused by heavy rains are verified in order to understand the vulnerability of the neighborhood in question. Georeferencing data is also used to assess the risk and susceptibility of hill and slope areas. In the context of adaptation, strategies are proposed that include the strengthening of drainage infrastructure, the implementation of early warning systems and adequate land use planning. For mitigation, the expansion of urban trees takes the lead as a strategy for reducing greenhouse gas emissions at the local level. Through this study, it is expected to provide a practical roadmap and valuable guidelines for environmental management and urban planning in neighborhoods susceptible to landslides and floods due to intense rains, thus contributing to the construction of safer and more resilient communities in a scenario of continuous climate change.
