To improve conservation planning measures in an ecosystem-based management context, we need to explore how the effects of these activities interact with different biodiversity components. In this study, we used a semi-quantitative method to assess the cumulative impacts of human activities on three biodiversity components (species richness, phylogenetic diversity, and functional diversity) in Tunisia's exclusive economic zone. For each of the nine activities considered, we developed an understanding of their effects from local studies and the expert opinion of stakeholders with country-speciic experience. We mapped the cumulative effects and the three biodiversity components and then assessed the degree to which these elements overlapped using an overlap index. This is the first time such an assessment has been made for Tunisia's marine ecosystems and our assessment highlight the inappropriateness of current conservation measures. The results of this study have specific application for the prioritization of future management actions. specialized Anthropogenic impacts species richness phylogenetic diversity functional diversity conservation planning TUNISIE MEDITERRANEE GABES GOLFE 036 038 040 021 17 1 190-201 2016 1108-393X https://www.documentation.ird.fr/hor/fdi:010066808 1108-393X [F B010066808] https://www.documentation.ird.fr/hor/fdi:010066808 https://www.documentation.ird.fr/intranet/publi/2016/05/010066808.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-06-02 2017-08-23 fdi:010066808 fre
