Hence, conservation measures of these ecosystems are urgently needed and should be combined with their sustainable uses. To address these issues, new research avenues for decision support systems have emphasized the role of the assessment of ecosystem services for establishing conservation priorities by avoiding monetarization approaches. These approaches, because they flatten the various values of nature by projecting them on the single monetary dimension, are often rejected by the stakeholders. We undertake a Q analysis to identify levels of consensus and divergence among stakeholders on the prioritization of ecosystem services provided by two French Mediterranean coastal lagoons areas. The results highlighted that there is a strong consensus among categories of stakeholders in the study sites about the paramount importance of regulation and maintenance services. Three groups of stakeholders, each sharing the same points of view regarding ecosystem services conservation, were identified for each study site. As a non-monetary valuation, Q methodology is very instrumental for the new pluralistic approach of decision support by capturing the values expressed by the stakeholders, without triggering a rejection reflex due to the monetarization. specialized Decision Making Value Plurality Non-monetary Valuation Q Methodology Coastal Lagoons Ecosystem Services FRANCE MEDITERRANNEE CORSE PALAVAS LAGON BIGUGLIA LAGON 036 020 040 154 1-13 2018 0921-8009 https://www.documentation.ird.fr/hor/fdi:010074081 10.1016/j.ecolecon.2018.07.018 0921-8009 [F B010074081] https://www.documentation.ird.fr/hor/fdi:010074081 https://www.documentation.ird.fr/intranet/publi/2018/10/010074081.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-11-07 2023-07-11 fdi:010074081 fre
