Abstract
Every year the world's population moves more and more to cities. Today 56% of all people live in cities, the forecast for 2050 suggests an increase in this figure to 60%. Sustainability for urban development is critical, as it addresses such issues as water and air pollution, waste management and resource consumption. Green cities use environmentally friendly practices to promote the health of the urban environment and, as a result, improve the quality of life. Nature-based solutions represent an interdisciplinary issue, including the competencies of urban planners, landscape designers, engineers, hydrologists, ecologists, economists, etc. and are critically needed for climate change adaptation. The paper is focused on the role of blue-green infrastructure as key adaptation strategy for climate change. Innovative approaches and technologies as examples of the best urban management strategies promoting a more sustainable urban environment resistant to climate change will be presented and discussed.
