NBSINFRA supports the enhancement of the local urban critical infrastructures protection against natural and manmade hazards through the Nature-based solutions (NBS) co-design and co-creation for a climate change resilient society. NBSINFRA will demonstrate that the Nature-based solutions are: (a) technically viable for the protection of critical infrastructures against hazards, (b) socially acceptable and cost-effective at the local scale; and (c) efficiently capable to increase the empowerment of communities, through the increase of their ecological, social, and economic resilience. To achieve those goals, NBSINFRA will establish five (5) representative European regions with an equal number of “City Labs”. NBSINFRA City labs shall assess the cost-effectiveness of NBS in the protection of local infrastructure and shall maximize their impact based on solutions which will be citizen owned and co-created by end-users and managers and civil society. NBSINFRA will provide a toolkit that the different stakeholders and society can use to compare and choose the most effective NBS for local critical infrastructure protection, being the main goal the support for the enhancement of the local urban critical infrastructure protection against hazards through NBS co-design, co-monitoring, and co-creation for a sustainable and resilient society.
