New report - Methodology for scaling mitigation and compensatory measures in tropical marine ecosystems

Since 2015, the French Coral Reef Initiative (IFRECOR) has been developing MERCI-Cor a method to assess the significance of an ecological impact, to ensure better Avoidance and Reduction of ecological losses in the mitigation hierarchy, and sizing compensatory measures, to offset last residual losses. This project involve scientific parties (University Montpellier 3, Lab. CEFE and CRIOBE), NGO (Blue finance), consulting company and public regulators (Florida Dept of Env. Protection, French Dept fo Env Protection Agencies – Guadeloupe, Réunion Island and New Caledonia, French Ministry of the Env. and Barbados Env. Protec. Agency). The method is affordable for consultants, construction companies as well as and public parties, regulators or NGO involved in marine and corals EIS. In order to assimilate the method, the Handbook 2 includes a general explanation of the MERCI-Cor method and an “in the field” example. The chapters describe specifically hierarchical phases of ecological compensatory mitigation:
  1. Method to assess losses and gains,
  2. Sizing ecological offset,
  3. Choice of compensation site and environmental engineering techniques,
  4. Implementation and monitoring of ecological performances.
