- 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.
- Twenty years of marine systematic conservation planning: a global scoping review for good practicesPublication . Fabbrizzi, Erika; Giakoumi, Sylvaine; Petza, Dimitra; Álvarez-Romero, Jorge; Beher, Jutta; Katsanevakis, Stelios; Lamine, Emna Ben; Colloca, Francesco; Domínguez Crisóstomo, Esther; Elliott, Michael; Flannery, Wesley; Galparsoro, Ibon; Kruse, Maren; McAteer, Ben; McIntosh, Emma; Resaikos, Vasilis; Stelzenmüller, Vanessa; Fraschetti, SimonettaHuman activities are exerting increasing pressure on the ocean, threatening marine biodiversity and the many benefits it provides to people. Allocating adequate space to enable the sustainable and equitable use of the ocean resources, while ensuring cost-effective conservation and restoration of marine ecosystem is particularly challenging in light of ambitious global, regional, and national commitments, such as those established by the Global Biodiversity Framework. In this context, Systematic Conservation Planning (SCP) offers a robust framework to prioritize conservation actions that safeguard biodiversity while minimizing costs and facilitating dialogue among maritime sectors. Methodology. The scoping review here assesses the challenges in SCP implementation and the obstacles preventing its adoption in guiding decision-making for the achievement of conservation objectives in harmony with human uses of marine resources. The 149 studies analysed, spanning from 2002 to early 2023, are distributed across all continents and encompass nine biogeographic realms.
- Unlocking the potential of other effective area-based conservation measures (OECMs) for achieving conservation targets: a global scoping reviewPublication . Petza, Dimitra; Amorim, Eva; Lamine, Emna Ben; Colloca, Francesco; Domínguez Crisóstomo, Esther; Fabbrizzi, Erika; Fraschetti, Simonetta; Galparsoro, Ibon; Giakoumi, Sylvaine; Kruse, Maren; Stelzenmüller, Vanessa; Katsanevakis, SteliosOther Effective Area-based Conservation Measures (OECMs), introduced by the Convention on Biological Diversity (CBD), refer to areas outside formal protected-area networks that deliver effective and enduring in situ biodiversity conservation. This scoping review systematically examined global approaches to identifying and evaluating potential OECMs. Analysing 99 studies covering 694 case studies and 237 000 potential sites, we found that potential OECMs are widespread, particularly in Asia and terrestrial environments, with most initiatives led by the environmental sector. Assessments relied largely on qualitative expert knowledge, with limited application of analytical methods. Although CBD criteria were commonly applied, contributions of related to ecosystem services and socio-cultural values were often overlooked. Effectiveness evaluations showed considerable uncertainty, with over one-third of case studies reporting inadequate evidence of conservation outcomes. The review emphasises the need for standardised assessment methodologies, improved decision-support tools, and socio-cultural integration to enhance OECM recognition, particularly under the 30 × 30 conservation biodiversity target.
