Estimating the social value of nature-based solutions in European cities.

By implementing nature-based solutions (NBS), cities generate value for their residents, such as health and wellbeing.

We offer a new metric to support investments for NBS by public and private actors for whom social value creation to residents is a core objective. [ABSTRACT FROM AUTHOR]
