New deliverable: Methodologies to assess ecosystem services provided by diadromous species
Quantifying the Total Economic Value (TEV) of ES is a complex task due to challenges encountered when trying to operationalise a common monetary assessment of the ES and obtain appropriate data. Therefore, the valuation of the ecosystem services associated with diadromous species implies using a range of methods with which an explicit monetary assessment can be provided. The methods exposed in this deliverable document are not new, but the novelty relies on their application to the diadromous species in the AA. The use of statement-based valuation techniques can complement the most traditional market-based valuation, but the quality of the valuation is highly dependent on the elicitation procedure.
Moreover, another improvement is linked to stakeholder involvement. Respondents’ statements from surveys are combined with group statements thanks to the engagement of DiadES stakeholders across the whole research.The methodological approach followed here has contributed to the development of a more participatory approach, which engages stakeholders (both internal and external of the project partnership) from the beginning of the study.
