Coral reef ecosystem services economic valuation experiences from the South Pacific
Economic approaches through ecosystem services (ES) valuation are increasingly recommended by conservation organisations to face main market externalities affecting biodiversity in general and coral reef ecosystems. In this dissertation, we will analyse the experience of two economic valuations of coral reef ecosystems in the Pacific focusing on two aspects. The first is to evaluate if current methods of Coral Reef Ecosystem Services Valuation (CRESV) permits to transmit a correct signal about ES and the second is to assess the impacts of results on policy-making and market externalities. The first study is the economic valuation of the coral reef ecosystems of New Caledonia. Financed by French Ministries of Environment and Oversea Territories, the main objective was to make visible the value of this ecosystem in the economy of the territory. The second one is a cost-benefit analysis of Marine Protected Areas in Vanuatu. Required by the French Development Bank, the aim was to realize an ex-post valuation of the impacts of marine biodiversity conservation on the economic development of the implicated villages and other stakeholders. More precisely, MPA impacts on the ES were quantified, total costs linked to each MPA were calculated and the C-B (Cost-Benefit) ratio and RoI (Return-on-Investment) were computed. More than 10 ecosystem services have been analysed with methods mainly based on financial values through producer surplus and avoided damage costs. Applied methods are classic ones with some improvements and originality such as the use of protein content equivalent for subsistence fishery, the larval stomach content to quantify links between reef ecosystem and pelagic fisheries, the application of the Advertising Image Analysis to tune the role of CR in the tourism motivation, the setup of experimental fishery to determine precise improvements in fishery productivity and the adaptation of a bio-physical model for coastal protection ES. Results in New Caledonia have permitted to make visible a contribution ...
