Webinar #32: Integrating ecosystem services in cost-benefit analysis for freshwater restoration

Nicolas Grondard (WUR), Sien Kok (WUR, Deltares), Isabell Lenz (BfG): Topic of this webinar: Across Europe, economic cost benefit analysis (CBA) is widely used to justify public investments and prioritize projects. Many EU member states have embedded CBA´s or similar instruments in their infrastructure planning processes. While some countries provide guidance on whether and how to execute CBA´s in specific contexts, there is little guidance on how to value Nature-based Solutions (NbS) or ecological restoration in a freshwater context specifically. In this webinar, we introduce an integrated approach that combines the hydrological model SWAT+ with ecosystem services monetary valuation to facilitate evaluation efforts. We demonstrate the impact of embedding a wide array of ecosystem services in an extended CBA rehabilitated river – and floodplain management strategies of the Rhine in the Netherlands, and finally demonstrate potential applications of such extended CBAs in waterways investment planning in Germany.
