- Broad-scale mapping of seafloor habitats in the north-east Atlantic using existing environmental dataPublication . Vasquez, Mickaël; Mata Chacón, D.; Tempera, Fernando; O'Keeffe, Eimear; Galparsoro, Ibon; Sanz Alonso, J. L.; Gonçalves, J. M. S.; Bentes, L.; Amorim, Patrícia; Henriques, Victor; McGrath, Fergal; Monteiro, Pedro; Mendes, Beatriz; Freitas, Rosa; Martins, Roberto; Populus, JacquesIf marine management policies and actions are to achieve long-term sustainable use and management of the marine environment and its resources, they need to be informed by data giving the spatial distribution of seafloor habitats over large areas. Broad-scale seafloor habitat mapping is an approachwhich has the benefit of producing maps covering large extents at a reasonable cost. This approach was first investigated by Roff et al. (2003), who, acknowledging that benthic communities are strongly influenced by the physical characteristics of the seafloor, proposed overlaying mapped physical variables using a geographic information system (GIS) to produce an integrated map of the physical characteristics of the seafloor. In Europe the method was adapted to the marine section of the EUNIS (European Nature Information System) classification of habitat types under the MESH project, andwas applied at an operational level in 2011 under the EUSeaMap project. The present study compiled GIS layers for fundamental physical parameters in the northeast Atlantic, including (i) bathymetry, (ii) substrate type, (iii) light penetration depth and (iv) exposure to near-seafloor currents andwave action. Based on analyses of biological occurrences, significant thresholds were fine-tuned for each of the abiotic layers and later used in multi-criteria raster algebra for the integration of the layers into a seafloor habitat map. The final result was a harmonised broad-scale seafloor habitat map with a 250 m pixel size covering four extensive areas, i.e. Ireland, the Bay of Biscay, the Iberian Peninsula and the Azores. The map provided the first comprehensive perception of habitat spatial distribution for the Iberian Peninsula and the Azores, and fed into the initiative for a pan- European map initiated by the EUSeaMap project for Baltic, North, Celtic and Mediterranean seas.
- 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.
