The new BBNJ (biodiversity beyond national jurisdiction) marine conservation agreement is impressive in scope but has since been rebranded by some as the “high seas treaty,” which risks biasing its interpretation by emphasizing the historical, but outdated, freedoms enjoyed by seafaring (and largely Western) nations.

Elizabeth Mendenhall of the University of Rhode Island joins this episode to discuss the treaty with co-host Rachel Donald, detailing the fascinating and complicated nature of ocean governance beyond the jurisdiction of states. The BBNJ agreement was designed to resolve some of these governance issues, but the text contains ample gray area in how the principles of “common heritage,” the concept that something belongs to all of humanity, will apply to the protection and extraction of resources from the water column and seafloor.

“The treaty design that we ended up with [from] my perspective is not really suited to achieve what it is we say we want to do, which is to create a big network of marine protected areas that's effective in terms of protecting biodiversity,” Mendenhall says.

To learn more and find links to the treaty documents, see the commentary Mendenhall co-authored for Mongabay about the topic earlier this year, here.
