This handbook for identifying, evaluating and reporting other effective area-based conservation measures in marine fisheries builds on a wealth of FAO fisheries guidance, including the FAO Technical Guidelines on Fisheries Management (FAO, 1997) and the various FAO Technical Guidelines for Responsible Fisheries (FAO, 2003; FAO, 2009a; FAO 2009b; FAO, 2011). The present document also draws on FAO’s experiences and lessons learned from workshops held in the Baltic, Mediterranean and Caribbean seas, as well as OECM discussions in Latin America and North Africa, inter alia.
