Résumé : International audience
Dudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization ofprotected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced bythe new regulation-based classification system [11]. Here we clarify that we do not advocate replacing thecurrent IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and thenew regulation-based classification when applied to MPAs. With an increasing number of MPA types beingimplemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socioeconomicbenefits is key for advancing conservation targets and policy objectives. Although the IUCN categoriescan be used both in terrestrial and marine systems, they were not designed to follow a gradient of impacts andthere is often a mismatch between stated objectives and implemented regulations. The new regulation-basedclassification system addresses these problems by linking impacts of activities in marine systems with MPA andzone classes in a simple and globally applicable way. Applying both the IUCN categories and the regulationbasedclasses will increase transparency when assessing marine conservation goals.

Résumé : International audience
Marine protected areas (MPAs) are a global conservation and management tool to enhance the resilience of linked social-ecological systems with the aim of conserving biodiversity and providing ecosystem services for sustainable use. However, MPAs implemented worldwide include a large variety of zoning and management schemes from single to multiple-zoning and from no-take to multiple-use areas. The current IUCN categorisation of MPAs is based on management objectives which many times have a significant mismatch to regulations causing a strong uncertainty when evaluating global MPAs effectiveness. A novel global classification system for MPAs based on regulations of uses as an alternative or complementing the current IUCN system of categories is presented. Scores for uses weighted by their potential impact on biodiversity were built. Each zone within a MPA was scored and an MPA index integrates the zone scores. This system classifies MPAs as well as each MPA zone individually, is globally applicable and unambiguously discriminates the impacts of uses.
