In view of the importance of other effective area-based conservation measures (OECMs) for biodiversity, and the need to improve individual countries’ capacity to report fisheries-related OECMs and understand how the fisheries sector contributes to current and future area-based biodiversity conservation objectives, FAO has been carrying out a series of activities to support countries to identify and implement OECMs. [Author] These activities include the organization of workshops and the development of practical guidance, as requested by FAO’s Committee on Fisheries (COFI). [Author] With the support of the Organización del Sector Pesquero y Acuícola del Istmo Centroamericano (Organization of the Fisheries and Aquaculture Sector of the Central American Isthmus [OSPECA]), FAO organized the workshop on other effective area-based conservation measures in fisheries-related areas in Latin America and the Caribbean. [Author] The workshop was held on 27–28 March 2023 in the city of San José, Costa Rica. [Author] This workshop supported Member Countries of the Commission for Small-scale and Artisanal Fisheries and Aquaculture of Latin America and the Caribbean (COPPESAALC), as well as regional and national fisheries-related organizations in the Latin American and Caribbean regions to: (i) apply CBD criteria for the identification of OECMs; (ii) understand the challenges, opportunities and needs that arise in the identification of fisheries‑related OECMs; and (iii) synthesize lessons learned and obtain recommendations. [Author] To achieve these objectives, topics discussed included: concepts and criteria for the identification, evaluation and reporting of OECMs; examples of OECMs in the world; conservation strategies in Latin America and the potential contribution of OECMs to these; the framework for fisheries governance and area-based management in Latin America; Argentina’s progress in recognizing OECMs; and the presentation of four case studies carried out in Chile, Costa Rica, Guatemala, and Mexico. [Author] The workshop enabled extensive exchanges on the difficulties of interpreting the concepts and criteria for the identification, evaluation, and reporting of OECMs, as well as the key points, challenges, and difficulties in analysing and considering potential OECMs. [Author]
