ENABLE employs a range of methods to identify, assess and facilitate a cost-effective implementation of green and blue infrastructure (GBI) for an optimized distribution of benefits and wider uptake. This project will provide further evidence for the multifunctionality of GBI solutions, adding to the growing evidence body for healthy ecosystems enhancing not only economic vitality and serving as effective climate change mitigation and adaptation tools, but also for improving human health and societal well-being. The framing of GBI as a multifunctional tool and the development of a robust evidence base supporting these claims will serve to increase the support of GBI by decision-makers and attract wider public and private cross-sectorial investment support. The project framework will enable the identification of (1) the environmental, social and economic benefits provided by GBI, (2) the societal demands, preferences and values attached to GBI and biodiversity, and (3) pathways for cities to align these considerations via the targeted provisioning of GBI. Significant stakeholder involvement underlies this approach, with the participation of local communities, practitioners and policy-makers playing a central role via the selected city case studies of Halle, Barcelona Metropolitan Region, Lodz, Stockholm, Oslo and New York.
