| contents | Unlocking the potential of other effective area-based conservation measures (OECMs) for achieving conservation targets: A global scoping review. Petza, Dimitra Amorim, Eva Lamine, Emna Ben Colloca, Francesco Dominguez Crisóstomo, Esther Fabbrizzi, Erika Fraschetti, Simonetta Galparsoro, Ibon Giakoumi, Sylvaine Kruse, Maren Stelzenmüller, Vanessa Katsanevakis, Stelios Conservation of Natural Resources Biodiversity Ecosystem Other 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. |
