![]() ![]() Although abundance and richness of species are important parameters in determining whether a NBS is biodiverse, they should not be the only factors. ![]() ![]() In fact, biodiversity is part of the EU’s official definition of NBS, which states that nature-based solutions “must benefit biodiversity and support the delivery of a range of ecosystem services”.īut how can cities ensure biodiversity lies at the heart of their NBS? And what are the must-have characteristics of an NBS rich in biodiversity?Įnhancing biodiversity is not only about enabling different plant and animal species to thrive. With its multi-pronged approach to societal challenges, NBS offer cities an effective way of mainstreaming biodiversity as part of other policy objectives, such as increasing urban resilience, creating economic opportunities and healthier places to live. Important parameters in measuring biodiversity were discussed, and potential benefits being reaped from biodiversity-driven NBS were highlighted, with a particular focus on the contexts of the CLEVER Cities, proGIreg, Connecting Nature and REGREEN projects. However, further commitment is required to effectively implement them, mainstream the conservation and sustainable use of biodiversity into all sectoral policies, and increase participation and stakeholder involvement.Īt ICLEI’s 9th Conference on Sustainable Cities and Towns ( Mannheim2020), the session “Biodiversity in Nature-based Solutions” debated concrete opportunities to bend the curve of biodiversity loss and ecosystem degradation in European cities via Nature-based Solutions (NBS). In Europe, several policies and governance options to enhance ecosystem protection, such as the new EU Biodiversity Strategy for 2030, are already available. The IPBES Global Assessment Report on Biodiversity and Ecosystem Services leaves no doubts regarding the severity of the biodiversity crisis: approximately 25 percent of species in Europe and Central Asia are already threatened with extinction in most of the plant and animal groups studied. Is biodiversity a necessity in nature-based urban interventions, or only a nice-to-have? ![]()
