Abstract Progressing climate change significantly affects the quality of life in cities. The related changes rainfall structure lead to an increased frequency extreme hydrological phenomena such as droughts and floods. increasing intensity is a particular threat urbanised areas, where due high degree area sealing, increase runoff volumes peak flow rate observed. Storm water drainage systems are often not adapted accommodate rainwater flows, which leads so-called urban On other hand, prolonged periods without precipitation may, turn, periodic shortages. Cities must implement adaptation strategy. One solutions for rational management implementation Blue-Green Infrastructure. These facilities modern solution supporting sewage networks operation, retention, improving article presents literature review on current state knowledge about Infrastructure stage these world. Solutions that newly introduced, necessarily invented, many places around world described. was limited period 2018–2023 indicate most up-to-date strategies.
