What the BBNJ negotiations might imply for the ocean’s ‘twilight zone’


Vrinda Suresh, Julia Mason and Doug Rader 

Over the past two weeks of August 2022, delegates from throughout the globe gathered in New York Metropolis for the Fifth Session of the Intergovernmental Convention, or IGC5, to develop a brand new treaty to guard biodiversity in offshore waters, known as the Biodiversity Past Nationwide Jurisdiction Settlement, or BBNJ Settlement. The BBNJ Settlement particularly addresses excessive seas waters, which embody all areas greater than 200 nautical miles from coastlines and fall outdoors the administration authority of particular person nations. The excessive seas make up almost 60% of Earth’s oceans.  

Teeming with life and woefully understudied, the excessive seas are more and more weak to impacts from human actions and stay below protected on account of gaps in worldwide governance. The rising recognition that oceans are shared and interconnected—that ocean processes and impacts have penalties for the complete globe—highlights the want for stronger cross boundary governance. Whether or not or how consensus is reached on the BBNJ Settlement could have lasting implications for a way we handle the intersecting problems with biodiversity safety, local weather change and fairness for our oceans. 

What’s the BBNJ Settlement? 

The BBNJ Settlement has been a few years within the making. In 2004, a U.N. Common Meeting decision first established a working group to check problems with biodiversity, conservation, and sustainability on the excessive seas. The working group really helpful a treaty on BBNJ in 2015 and the First Session of the Intergovernmental Convention was lastly held in 2018, with subsequent periods in 2019 and 2022. 

If consensus is reached, the BBNJ Settlement could be the primary legally binding treaty to preserve and promote sustainable use of marine biodiversity within the excessive seas. The settlement focuses on 4 areas: marine genetic assets, area-based administration instruments like marine protected areas, environmental affect assessments and capability constructing and switch of marine know-how. 

Outcomes of IGC5 

At IGC5, important progress was made on all 4 areas of the treaty bundle, however delegates failed to achieve a consensus on the treaty textual content and determined to droop the session and resume negotiations in early 2023.  

A number of the details of rivalry from previous negotiations carried over to IGC5, together with the connection of the BBNJ Settlement to present worldwide our bodies that govern ocean assets, a few of which already handle components of biodiversity. Many points additionally broke down alongside growing/developed nation traces, together with how advantages from excessive seas assets will be accessed and shared. These can be precedence points within the subsequent spherical of negotiations to safe ratifications and guarantee efficient and equitable implementation of the treaty. 

Inventive downside fixing can be essential to safe a robust excessive seas treaty, and lots of stay optimistic in regards to the prospect of reaching a consensus when negotiations resume. 

The excessive seas and local weather change 

Although local weather change is just not talked about a lot within the present treaty textual content, the BBNJ Settlement has the potential to enhance marine biodiversity conservation and leverage alternatives to battle local weather change.  

The oceans retailer extra carbon than all forests and soils mixed, however local weather change and different stressors have degraded pathways to naturally retailer carbon in our oceans. By restoring pure pathways and defending present pathways, we are able to retailer extra carbon in our oceans to be able to mitigate local weather change. Species dwelling within the oceans’ “Twilight Zone,” or mesopelagic zone, could also be important to ocean carbon storage processes and local weather change mitigation. The BBNJ Settlement might assist to fill gaps in safety for these species. 

Filling the governance hole within the Twilight Zone 

Though business fishing within the Twilight Zone is just not nicely established, there may be rising curiosity in exploiting mesopelagic species. Some nations have already commenced exploratory mesopelagic fishing, which raises issues in regards to the lack of rules in place for overseeing excessive seas mesopelagic fisheries and our lack of information about how fishing would possibly disturb Twilight Zone ecosystems. 

The Settlement’s provisions on environmental affect assessments and area-based administration instruments might be necessary routes for serving to to guard mesopelagic life and its local weather change-mitigating potentialthough bigger scale safety could also be wanted to maintain carbon sequestration providers. Moreover, worldwide governance of excessive seas assets might assist make sure that business and dietary advantages of any mesopelagic fishing are distributed throughout nations fairly than completely accruing to greater earnings nations with the technological capability required to reap these species. 

How the BBNJ Settlement can assist 

Regional fishery administration organizations already handle sure excessive seas species however most focus largely or completely on commercially necessary and globally traded tunas and “tuna-like” species. Solely about 4.8% of fish species which have been noticed in areas past nationwide jurisdiction are formally assessed and successfully managed by these organizations. Nonetheless, the South Pacific Regional Fisheries Administration Group has a considerably broader mission that features extensively distributed jack mackerel and jumbo flying squid, in addition to some deep sea related species that might enable mesopelagic conservation. As well as, two polar conservation establishments, the Fee for the Conservation of Antarctic Residing Marine Assets and the Arctic Council even have broader missions that might enable mesopelagic conservation. For instance, the Fee for the Conservation of Antarctic Residing Marine Assets already regulates fisheries focusing on vertically migrating krill. 

By its environmental affect evaluation provisions, the BBNJ Settlement might help assessments of mesopelagic ecosystems, together with their capacity to maintain fisheries with out impairing their important carbon processing features. Whereas regional fishery administration organizations do conduct affect assessments, they have an inclination to concentrate on particular shares fairly than broader ecosystem processes and impacts, partially on account of a scarcity of capability. The BBNJ Settlement might standardize and improve the standard of those assessments by setting minimal worldwide pointers and offering for bigger scale strategic environmental assessments. This might be helpful in figuring out areas or species which can be notably necessary to guard for his or her carbon storage capability. 

The treaty’s area-based administration provisions might additionally probably assist with the conservation of mesopelagic fish. Underneath the draft Settlement, areas requiring safety are to be recognized primarily based on the perfect accessible science and conventional data, taking into account precautionary and ecosystem approaches. Standards for identification of areas to guard embody their “ecological connectivity” and “necessary ecological processes occurring therein,” which might be relevant to the mesopelagic zone. The problem can be to adapt this software, which up to now has targeted totally on greater stage protections for a lot smaller areas, fairly than area-wide conservation for extra broadly distributed species. The problem can be to adapt this governance software for ecosystem extensive conservation for broadly distributed species fairly than excessive stage protections for smaller areas.  

Wanting Forward 

BBNJ Settlement might present a framework to assist help assessments and conservation of mesopelagic ecosystems, establish areas or species of explicit significance to the mesopelagic meals net and carbon storage processes and maybe information sustainable administration of rising mesopelagic fisheries. If carried out nicely, it has the potential to help regional fishery administration organizations and different excessive seas regulatory our bodies whereas serving to to address pressing gaps in worldwide ocean governance. Though delegations proceed to disagree about sure factors in the Settlement, many are optimistic about reaching a consensus on the resumed IGC5 negotiations. Securing a robust excessive seas treaty would assist preserve marine life and pure assets, set up devices to handle rising threats to our oceans and create important local weather co-benefits.
