The NATURVATION project has produced 775 European Assessment Maps as well as a set of City-scale Assessment Maps on Malmö, Barcelona and Utrecht. The European maps show the potential of nature-based solutions to address climate change adaptation and mitigation across 775 European cities. A set of tools using open-source GIS-based modelling was used to quantify two benefits of urban nature-based solutions (i.e. heat mitigation and carbon storage) under three different scenarios (i.e. reference, green and grey), that differ in the amount and location of nature-based solutions within the cities. The City-scale maps show the potential of nature-based solutions to address climate change adaptation and mitigation in more-fine grained city-scale assessment, including three selected cities (Malmö, Barcelona, Utrecht), and quantify benefits of urban nature-based solutions under six different scenarios and six different indicators.
