Defining and quantifying coral reef resilience now represents a critical management objective, but there is still little consensus on the approach and the indices to be used. In this study, we develop a multi-factor reef recovery index based on the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method to assess the vulnerability of several insular coral reefs in the South Western Indian Ocean (SWIO) from 2016 to 2018. We showed, that in the wake of a regional bleaching event in 2016, the most isolated reefs of Europa, which is characterized by low direct human impact had the highest recovery potential. On the contrary, islands that are more prone to direct human influence (i.e., La Reunion and Rodrigues) displayed the lowest recovery potential. specialized Coral reefs Resilience Indicators TOPSIS South Western Indian Ocean OCEAN INDIEN ILES REUNION RODRIGUES MAYOTTE 036 082 020 147 109952 [13 ] 2023 1470-160X https://www.documentation.ird.fr/hor/fdi:010087637 10.1016/j.ecolind.2023.109952 1470-160X [F B010087637] https://www.documentation.ird.fr/hor/fdi:010087637 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-06/010087637.pdf IRD - Base Horizon / Pleins textes 2023-06-30 2025-07-21 fdi:010087637 fre
