- Turning the tide on protection illusions: The underprotected MPAs of the ‘OSPAR Regional Sea Convention’Publication . Roessger, Julia; Claudet, Joachim; Horta E Costa, BarbaraContracting Parties of the Convention for the Protection of the Marine Environment of the North-East Atlantic (the 'OSPAR Convention') have agreed to establish an effective network of marine protected areas (MPAs). While the network is currently covering approximately 7% of the North-East Atlantic, the extent to which existing MPAs appropriately harbour protection remains unknown. Using the regulation-based classification system, we assessed the levels of protection of 946 zones belonging to 476 strictly marine OSPAR MPAs. We show that only 0.03% of the OSPAR MPA network is covered with full or high protection levels, which are the protection levels exhibiting significant conservation benefits. According to this study, more than 60% of MPAs are unprotected, leading to uncertainties about their potential to deliver positive conservation outcomes. MPA coverage alone should not be used as an indicator for MPA performance, but when presented with the actual protection levels, a light can be shed on MPA quality. To be able to reach the 2030 ocean targets agreed under the European Biodiversity Strategy, to which most OSPAR Contracting Parties are committed, substantial efforts are required not only to strategically enlarge the MPA network coverage to 30% but mostly to reach the EU sub-target of 10% of strict protection. Enhancing effective protection by increasing the coverage of fully and highly protected areas to safeguard marine ecosystems is urgently needed to sustainably support human well-being.
- A regulation-based classification system for marine protected areas: A response to Dudley et al. [9]Publication . Horta e Costa, Bárbara; Claudet, Joachim; Franco, Gustavo; Erzini, Karim; Caro, Anthony; Gonçalves, Emanuel J.Dudley et al. [9] commented on our paper [11], arguing that the current IUCN objective-based categorization of protected areas, which is also used in marine protected areas (MPAs), should not be abandoned and replaced by the new regulation-based classification system [11]. Here we clarify that we do not advocate replacing the current IUCN categories, but highlight the benefits of using both the objective-based IUCN categories and the new regulation-based classification when applied to MPAs. With an increasing number of MPA types being implemented, most of them multiple-use areas zoned for various purposes, assessing ecological and socio-economic benefits is key for advancing conservation targets and policy objectives. Although the IUCN categories can be used both in terrestrial and marine systems, they were not designed to follow a gradient of impacts and there is often a mismatch between stated objectives and implemented regulations. The new regulation-based classification system addresses these problems by linking impacts of activities in marine systems with MPA and zone classes in a simple and globally applicable way. Applying both the IUCN categories and the regulation based classes will increase transparency when assessing marine conservation goals.
- Guidance on marine protected area protection level assignments when faced with unknown regulatory informationPublication . Driedger, Alex; Sletten, Jennifer; Colegrove, Claire; Vincent, Timothé; Zetterlind, Virgil; Claudet, Joachim; Horta E Costa, BarbaraStrong human use regulations are an important precondition for marine protected area (MPA) effectiveness. Distinguishing MPAs based on their protection levels has shown advantages, but the availability of regulatory information about allowed activities is a major roadblock towards completing assessments at scale. Here, using a California case study, we explore assigning MPA protection levels following the regulation-based classification system (RBCS) under different scenarios of incomplete regulatory information. In the first group of scenarios (A), only readily available information was used, i.e., information contained in direct MPA implementing regulations and management plans. In the second group (B), information was limited to the activities in ProtectedSeas' Navigator that matched those in the RBCS. From group A, 99% and 100% correct classification of fully and highly protected areas, respectively, were obtained when treating unknown aquaculture, bottom exploitation, and bottom extraction as 'prohibited' and boating, anchoring, and fishing activities as 'allowed'. High classifi-cation accuracy was also obtained for moderately, poorly, and unprotected areas. From group B, 92% and 94% correct classification of fully and highly protected areas were obtained when using the same assumptions for non -fishing activities but using Navigator's Level of Fishing Protection (LFP) score to guide assumptions about un-known fishing activities. Correct classification rates were poorer with different assumptions. Regulation-based MPA evaluation systems can reliably identify fully and highly protected areas in the face of unknown infor-mation, when assumptions about unknown information are guided by contextual indicators such as generally regulated human activities and/or overall level of fishing restriction.
- A regulation-based classification system for marine protected areas (MPAs)Publication . Horta e Costa, Bárbara; Claudet, Joachim; Franco, Gustavo; Erzini, Karim; Cara, Anthony; Gonçalves, Emanuel J.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. (C) 2016 The Authors. Published by Elsevier Ltd.
- Ocean protection quality is lagging behind quantity: Applying a scientific framework to assess real marine protected area progress against the 30 by 30 targetPublication . Pike, Elizabeth P.; MacCarthy, Jessica M. C.; Hameed, Sarah O.; Harasta, Nikki; Grorud‐Colvert, Kirsten; Sullivan‐Stack, Jenna; Claudet, Joachim; Horta E Costa, Barbara; Gonçalves, Emanuel J.; Villagomez, Angelo; Morgan, LanceThe international community set a global conservation target to protect at least 30% of the ocean by 2030 ("30 x 30") to reverse biodiversity loss, including through marine protected areas (MPAs). However, varied MPAs result in significantly different conservation outcomes, making MPA coverage alone an inadequate metric. We used The MPA Guide framework to assess the the world's largest 100 MPAs by area, representing nearly 90% of reported global MPA coverage and 7.3% of the global ocean area, and analyzed the distribution of MPA quality across political and ecological regions. A quarter of the assessed MPA coverage is not implemented, and one-third is incompatible with the conservation of nature. Two factors contribute to this outcome: (1) many reported MPAs lack regulations or management, and (2) some MPAs allow high-impact activities. Fully and highly protected MPAs account for one-third of the assessed area but are unevenly distributed across ecoregions in part because some nations have designated large, highly protected MPAs in their overseas or remote territories. Indicators of MPA quality, not only coverage, are needed to ensure a global network of MPAs that covers at least 30% of the ocean and effectively safeguards representative marine ecosystems from destructive human activities.
- Over 80% of the European Union’s marine protected area only marginally regulates human activitiesPublication . Gorjanc, Sašo; Sletten, Jennifer; Vincent, Timothé; Laznya, Anastasiya; Vaidianu, Natașa; Claudet, Joachim; Young, Juliette; Horta e Costa, Barbara; Aminian Biquet, JulietteTo address the ongoing deterioration of marine ecosystems and its consequences on livelihood, the European Union (EU) now aims to achieve 30% coverage of marine protected areas (MPAs), with 10% under strict protection per region. Here, we provide the first assessment of protection levels of EU MPAs, describing the level of legal restrictions of activities using the MPA Guide framework. While MPAs covered 11.4% of EU national waters in 2022, 0.2% were fully or highly protected. As much as 86% of MPA coverage showed low levels of protection or would not be considered compatible with conservation objectives, as they allow industrial activities. Most MPA coverage showed minimal protection across member states, sea regions, and legal types of MPAs. The EU MPA network likely provides limited ecological outcomes. Reaching the EU's 10% strict protection target will require radical changes to the regulation of activities in EU MPAs.
- Assessments of expected MPA outcomes can inform and improve biodiversity conservation: case studies using the MPA guidePublication . Sullivan-Stack; Jenna; Ahmadia, Gabby N.; Andradi-Brown, Dominic A.; Barron, Alexandra; Brooks, Cassandra M.; Claudet, Joachim; Field, Laurel C.; Giakoumi, Sylvaine; Gonçalves, Emanuel; Groulx, Natalie; Harris, Jean; Jessen, Sabine; Johnson, Steven Mana'oakamai; MacCarthy, Jessica M.C.; Maricato, Guilherme; Morgan, Lance; Nalven, Katharine Bear; Nocito, Emily S.; Pike, Elizabeth P.; Sala, Enric; Tardin, Rodrigo; Villagomez, Angelo; Wright, Kendyl; Grorud-Colvert, Kirsten; Horta e Costa, BarbaraGlobal, regional, and national targets have been set to protect and conserve at least 30 % of the ocean by 2030, in recognition of the important benefits of healthy ocean ecosystems, including for human well-being. Many of these targets recognize the importance of the quality, not just quantity, of areas that are included in the 30 %, such as marine protected areas (MPAs). For example, the Convention on Biological Diversity's Global Biodiversity Framework Target 3 calls for areas to be effectively conserved and managed, ecologically representative, well-connected, and equitably governed. Protecting a percent area is not the sole goal - protection must be effective and equitable. To better understand the quality of biodiversity conservation afforded, in addition to the quantity of area protected, we looked at MPAs across 13 studies that used The MPA Guide and related tools to track Stage of Establishment and Level of Protection as measures of expected biodiversity conservation outcomes across diverse locations, scales, and cultural, political, and conservation contexts. We show that standardized assessments of MPA quality can help to (1) evaluate and improve existing MPAs; (2) plan new MPAs; (3) compare the quality of MPA protection across various scales; (4) track MPA quality, including progress towards coverage targets; (5) enable clear communication and collaboration, and (6) inform actions needed to achieve policy targets and their underlying environmental and social goals, among others. We share common opportunities, challenges, and recommendations for tracking MPA quality at various scales, and using these quality assessments to measure progress towards global targets.
- Regulations of activities and protection levels in marine protected areas of the European Union: a dataset compiled from multiple data sourcesPublication . Aminian Biquet, Juliette; Colegrove, Claire; Driedger, Alex; Raudsepp, Nicole; Sletten, Jennifer; Vincent, Timothé; Zetterlind, Virgil; Roessger, Julia; Laznya, Anastasiya; Vaidianu, Natașa; Claudet, Joachim; Young, Juliette; Horta e Costa, BarbaraThe dataset gathers available regulations of human activities and protection levels of Marine Protected Areas (MPAs) of the European Union (EU). The MPA list and polygons were extracted from the MPA database of the European Environment Agency (EEA) and completed with available zoning systems (all were filtered for their marine area reported under the Marine Strategy Framework Directive). Fully-overlapping MPAs were merged. In the resulting dataset, MPA features are provided (gathered from EEA, WDPA, ProtectedSeas), including the year of designation, designation types (e.g., national, Natura 2000) and subtypes (e.g., reserves, national parks), database identifiers (WDPA, Natura 2000, OSPAR, etc.), IUCN categories, and main protection focus. We provide summarized data on maritime activities that overlap with MPA polygons from two types of datasets: activities-focused datasets (national marine spatial plans, and additional European and regional databases, like EMODnet) and MPA-focused datasets gathering data from management plans (ProtectedSeas, expert-based assessments about OSPAR and Portuguese MPAs). This dataset therefore compiles data that could be gathered from accessible legal frameworks regarding aquaculture, fisheries, anchoring, infrastructures (including harbors and renewable energy), mining, transport, coastal land-based uses (desalinization, sewage plants) and other non-extractive uses (e.g., recreational), making them readily accessible. Using the MPA Guide classification system, we computed two scenarios of potential impact for each activity, which were used to assess two scenarios of protection levels per MPA. Some MPAs could not be associated with any MPA features, regulations, or protection levels. Finally, we detail the protocol to match information from multiple databases (e.g., with MPA polygons formatted differently) and provide a quality check by comparing this dataset to previous assessments. This dataset was used to analyze MPAs' protection levels across countries, regions and MPA features (e.g., IUCN categories, designations). It was also used to investigate the sources of information available and the levels of regulations for each maritime activity in EU MPAs. This dataset can therefore be used for further analyses on the use of EU MPAS to regulate activities and to compare with future assessments or with additional data we did not have access to (e.g., gathered at national scale). Such research is crucial to plan and monitor the implementation of the EU 2030 Biodiversity Strategy, targeting 10% of strictly protected MPAs in each sea region.
