Based on an extensive model intercomparison, we assessed trends in biodiversity and ecosystem services from historical reconstructions and future scenarios of land-use and climate change. During the 20th century, biodiversity declined globally by 2 to 11%, as estimated by a range of indicators. Provisioning ecosystem services increased several fold, and regulating services decreased moderately. Going forward, policies toward sustainability have the potential to slow biodiversity loss resulting from land-use change and the demand for provisioning services while reducing or reversing declines in regulating services.
Les scientifiques notent: "Compte tenu des effets négatifs potentiellement synergiques de l'utilisation des terres et du changement climatique sur la biodiversité, nos résultats suggèrent que les efforts de conservation et de restauration devraient être prioritaires à l'échelle mondiale en tant que solutions climatiques naturelles nécessaires. » DOI: 10.1126/science.adn3441
