The management of bottom fisheries and the protection of ecosystems in the high seas have received increased attention at the international level during the last decade, and in particular subsequent to the passing of UNGA Res. 61/105 that called for actions by Regional Fisheries Management Organizations or Arrangements (RFMO/As) with the competence to regulate bottom fisheries to take actions by the end of 2008 to address issues relating deep-sea fisheries and vulnerable marine ecosystems. FAO developed, through a consultative process, the “International Guidelines for the Management of Deep-Sea Fisheries in the High Seas” that were adopted in 2008. These assisted States and RFMO/As to undertake the actions called for by the UNGA. The present publications provide an overview of how States and RFMOs to date have tried to implement the above resolution and applying the techncial guideance contained in the FAO DSF Guidelines with respect to Vulnerable Marine Ecosystems. It details VME processes undertaken globally in ABNJ. The publication is composed of regional chapters, decsribing the processes and measures adopted in the different ocean regions, pulling these together in a global overview. This will form a sister volume to the “Worldwide review of bottom fisheries in the high seas” (WWR) that was first published by FAO in 2009.
