Co-design of restorative NBS evaluation criteria, constraints and opportunities NICHES project aims to advance knowledge on sustainable transformations of cities based on restorative nature-based solutions to enhance water retention capacities to mitigate impacts from floods and combined sewer overflows on aquatic ecosystems. This milestone corresponds to Task 3.1 Community vulnerability assessment (MS3.1) and aims to co-create evaluation criteria for nature-based solutions and identify constraints and opportunities in urban waterscape-wide rehabilitation plans through nature-based solutions. To reach these objectives, a survey and two workshops have been conducted in the Metropolitan Area of Barcelona. The survey and the first workshop asked participants about the importance they attribute to three dimensions for the evaluation criteria of nature-based solutions being vulnerability, multifunctionality and sustainability. A second workshop conducted identified stakeholders' views on the current state and the desired future of the urban water system of the Barcelona Metropolitan Area.
