Biodiversité

Le changement climatique impacte la nature, y compris dans les espaces naturels protégés. Sur le littoral, l’augmentation de la température, l’élévation du niveau des océans ou la diminution du pH de l’eau de mer entraînent des modifications des écosystèmes. Les gestionnaires sont donc confrontés à la nécessité d’adapter leurs pratiques. Le projet Natur’Adapt, porté par Réserves Naturelles de France, a été développé pour les accompagner dans cette démarche.

The International Union for the Conservation of Nature, a global environmental organization, lists approximately 1,200 marine species worldwide that are considered vulnerable, threatened, or at-risk of extinction. Many are provided legal protection through national laws requiring research and management measures aimed at recovering and maintaining the species at a sustainable population level. Integral to the policy decision process involving the management and recovery of marine species is the consideration of trade-offs between the economic and ecological costs and benefits of protection. This suggests that economics, at its core the study of trade-offs, has a significant role. In the U.S. a somewhat traditional use of economics in protected species research and management has involved cost minimization or cost-effectiveness analyses to help select or prioritize conservation actions.
