E. auteur aut IRD text journalArticle eng text/pdf reformatted digital access The amount of ocean protected from fishing and other human impacts has often been used as a metric of conservation progress. However, protection efforts have highly variable outcomes that depend on local conditions, which makes it difficult to quantify what coral reef protection efforts to date have actually achieved at a global scale. Here, we develop a predictive model of how local conditions influence conservation outcomes on similar to 2,600 coral reef sites across 44 ecoregions, which we used to quantify how much more fish biomass there is on coral reefs compared to a modeled scenario with no protection. Under the assumptions of our model, our study reveals that without existing protection efforts there would be similar to 10% less fish biomass on coral reefs. Thus, we estimate that coral reef protection efforts have led to approximately 1 in every 10 kg of existing fish biomass. specialized marine conservation marine protected area coral reef fisheries social-ecological MONDE 036 040 082 020 Proceedings of the National Academy of Sciences of the United States of America 121 42 e2308605121 [9 p.] 2024 0027-8424 https://www.documentation.ird.fr/hor/fdi:010092095 10.1073/pnas.2308605121 0027-8424 [F B010092095] https://www.documentation.ird.fr/hor/fdi:010092095 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-12/010092095.pdf IRD - Base Horizon / Pleins textes 2024-12-04 2026-06-12 fdi:010092095 fre
