Ecologically and Biologically Significant Areas (EBSAs) as an enabling mechanism for transboundary marine spatial planning

As the new global biodiversity targets kick in, the signatories to the Convention of Biological Diversity (CBD) are searching for means to fulfil their obligations. Fortunately, more than a decade ago a long-neglected solution was created for the marine environment. The ecologically or biologically significant marine areas (EBSAs) provide a means for opening discussions around the management of large marine areas, ideally with conservation as a core priority. While the biological and ecological criteria for the selection of the EBSAs is clearly outlined, there is little clarity on the means to manage or govern these areas. The conservation and management measures are left as a matter to be resolved by those states which maintain some form of jurisdiction over regions within an EBSA. Of course, these measures must be in accordance with international law. Within the Mediterranean there are 15 EBSAs which have been identified and recognised by the parties of the UNEP regional seas programme. For the past four years, technical and scientific discussions have looked to move the EBSA recognition of the Southern Adriatic Ionian Straight (SAIS) forward and identify potential governance frameworks. This work has included a biodiversity threat analysis, a legal and governance review, and a preliminary spatial prioritization. We report on the processes undertaken, the policy implications for the SAIS-EBSA and the way forward. This work has implications not only for this region but for other regions within the Mediterranean and beyond.
