Ecosystem based approaches to adaptation (EBA) are defined as “the use of biodiversity and ecosystem services as the part of an overall adaptation strategy against the adverse effects of climate change”. Although current adaptation strategies tend to focus on technical, structural, social and economic developments, ecosystems and biodiversity can play a significant role in societal adaptation to climate change. These measures promote nature-based solutions such as support of green infrastructure: green roofs - increasing the energy efficiency of buildings, green walls, and green public spaces and the use of blue Infrastructure: increasing water retention, permeability of the terrain in the cities, lakes and rivers in the city.
EBA has been proposed as a “natural” solution to adaptation to climate change and is supposed to enhance the adaptive capacity of human society through the sustainable management and restoration of ecosystem services, while providing multiple benefits to human society.
