As climate change is further threatening our planet and society, nature-based solutions (NbS) are increasingly recognized as impactful measures to address such problems and enhance urban resilience, biodiversity, and human well-being. Yet, their adoption often remains overlooked and misjudged, due to their complexity and sometimes not quite complete understanding of their potential, when dealing with important challenges. Therefore, this research seeks to facilitate the implementation of NbS across different European cities, helping decision-makers and communities take informed decisions and navigate the vast information that has been produced on the topic, eventually improving the environmental and social conditions of specific urban spaces at a time, and avoiding major risks of maladaptation or dissatisfaction with the project.
