NATURVATION is developing a comprehensive approach to assessing the value of nature-based solutions.

A first step in our approach has been to compile a Financial and Economic Values Database that records the values that have been calculated for nature-based solutions. Developed by Utrecht University, our database currently includes 205 values assigned to nature-based solutions from 105 studies drawn from the academic work published on the economic valuation of environmental services over the past 40 years. It covers both revealed preference (RP) and stated preference (SP) methods, and include values elicited by means of contingent valuation and choice modelling (SP), as well as hedonic pricing and benefit transfer methods (RP).
