Este trabalho discute a vulnerabilidade do sistema de drenagem urbana da cidade do Recife sob o aspecto urbanístico e climático (precipitações intensas e oscilações de maré). Realizou-se uma pesquisa bibliográfica, apresentando um diagnóstico expedito sobre as peculiaridades da drenagem urbana da cidade, discutindo as intervenções estruturais realizadas no sistema e as medidas implementadas para o enfrentamento das mudanças climáticas. Verificou-se que as ações e medidas que propiciem uma melhor adaptação para a adequação do sistema de drenagem na região, diante da influência das alterações climáticas, ainda são muito tímidas. De uma maneira geral, conclui-se pela necessária gestão integrada do saneamento, a efetiva aplicação das medidas não estruturais, e a utilização combinada de técnicas compensatórias e estruturais que vise à sustentabilidade do sistema, considerando também, os efeitos das alterações climáticas.

This paper discusses the vulnerability of urban drainage system of the city of Recife considering the urban and climate aspect (intense rainfall and tide oscillations). It presents an expeditious diagnosis on the urban drainage peculiarities of the city, discussing the structural interventions carried out in the system and the measures implemented for coping with climate change, considering the aspect of the urban drainage. It was verified that the actions and measures that allow a better adaptation to the adequacy of the drainage system in the region, given the influence of climate change, are still very timid. It is concluded, in general, in favor of the necessary integrated management of sanitation, the effective implementation of non-structural measures, and the combined use of compensatory and structural techniques aiming at the sustainability of the system, considering the effects of climate change as well.
Keywords: Urban planning; climate change; urban drainage.
