In this document you can find a visual representation of the different types of ecosystems and most relevant societal challenges in the context of NBS, with the aim to simplify and communicate these concepts, while inspiring NBS good practices. || The European Commission defines Nature-based solutions (NBS) as “solutions that are inspired and supported by nature, which are cost-effective, simultaneously provide environmental, social and economic benefits and help build resilience”. NBS must benefit biodiversity and support the delivery or a range of ecosystem services. Such solutions bring more, and more diverse, nature and natural features and processes into cities, landscapes and seascapes, through locally adapted, resource-efficient and systemic interventions. This definition is aligned with the IUCN and the recently internationally adopted UNEA-5 definition.
