The deep and distant waters of marine areas beyond national jurisdiction (ABNJ) cover nearly half of the Earth’s surface and host a significant portion of its biodiversity. Previously beyond the reach of human activities, recent scientific and technolog-ical advancements have enabled us to explore these areas, and a growing human population and its ever-increasing demand for resources is now driving the exploitation of their resources.

Shipping and fishing have intensified and expanded in recent decades. Seabed mining and bioprospecting are developing, and a range of novel activities may be on the horizon [1] (World Ocean Assessment, 2016; Merrie et al., 2014; Ramirez-Llodra et al., 2011). The impacts of these activities on marine ecosystems are being compounded by climate change and ocean acidification (Gattuso et al., 2015; Levin & Le Bris, 2015).

Cognisant of the growing threats to biodiversity in ABNJ and gaps in the current legal framework, an intergovernmental conference (IGC) has been convened to elaborate an interna-tional legally binding instrument (ILBI) for the conservation and sustainable use of marine biodiversity beyond national jurisdic-tion (BBNJ), under the auspices of the United Nations Conven-tion on the Law of the Sea (UNCLOS).

The negotiations focus on a ‘package deal’ of issues, comprising: marine genetic resources (MGRs); area-based management tools (ABMTs), including marine protected areas (MPAs); environmental impact assessments (EIAs); and capacity building and technology transfer. As the agreement is intended to adress conservation and sustainable use as a whole, this policy brief explores some potential avenues for strengthening the overall framework beyond the package deal elements.


I. Advancing the vision of UNCLOS 

The United Nations Convention on the Law of the Sea, the “Constitution for the Ocean” (Koh, 1982),[2] aimed to establish a “legal order for the seas and oceans [to] facilitate interna-tional communication, and… promote the peaceful uses of the seas and oceans, the equitable and efficient utilisation of their resources, the conservation of their living resources, and the study, protection and preservation of the marine environment”. [3]

The current negotiations provide a unique and timely oppor-tunity to advance the ambitious vision of UNCLOS by strength-ening the legal framework for high seas biodiversity. The new agreement should:

  • Be based on a set of best-practice governance principles, including the precautionary principle, ecosystem-based management and transparency;
  • Stimulate enhanced cooperation and coordination between States, intergovernmental organisations and stakeholders;
  • Operationalise existing conservation obligations, e.g. by clarifying and elaborating the duty to cooperate to adopt conservation measures and specifying a process for EIAs;
  • Build global ocean science capacity and advance the devel-opment and sharing of technologies;
  • Ensure fair access and ability to share the benefits of marine resources; and
  • Provide strong global oversight to ensure effective conser-vation and sustainable use of marine biodiversity.


II. Providing global oversight 

The governance framework for ABNJ is often characterised as fragmented, with a wide variety of international instruments and institutions addressing particular sectors or geographic regions. For example, shipping and seabed mining are managed at the global level through the International Maritime Organ-ization (IMO) and the International Seabed Authority (ISA) respectively, while fishing is managed regionally by a myriad of Regional Fisheries Management Organizations (RFMOs).

These bodies are not required to take into account the mandates and management measures of overlapping or neigh-bouring organizations and there is little cooperation and coor-dination between them (Wright et al., 2018). While there has been some success in advancing cooperation, the current frame-work makes it practically impossible to manage cumulative impacts and ensure ecosystem-based management (Wright and Rochette, 2018). [4] Furthermore, in some regions there are no competent organizations to regulate human activities or coordi-nate management (Freestone, 2018).

In order to address these challenges, strong international oversight is required through a treaty that will:

Empower a global body to make recommendations and take decisions based on a comprehensive, multi-sector, ecosystem view of the marine environment;

  • Provide decision-makers with the best available scientific information, for example through a dedicated scientific body and mechanisms for independent scientific review;
  • Facilitate the cooperation and coordination between management bodies, including by obliging States Parties to pursue management actions within relevant competent organizations and instruments;
  • Bring increased transparency to the governance of the high seas;
  • Improve the logistical and funding mechanisms for the collection, aggregation and dissemination of data and knowledge; and
  • Promote greater accountability through robust public reporting, compliance and dispute-resolution mechanisms.


III. Strengthening sectoral and regional governance 

Strong regional and sectoral management organisations and cooperative mechanisms could underpin global standards and play a key role in implementation of the new treaty. Many sectoral organisations have developed specialised knowledge and management practices, while regional-level cooperation has long been a cornerstone of international environmental law, allowing parties to account for local circumstances, challenges and needs.


These efforts can offer lessons learned, platforms for scientific data and knowledge exchange, and mechanisms forconvening States and stakeholders. There is however both a need and opportunity to increase the interplay between the regional, sectoral and global levels of ocean governance. A new treaty could facilitate successful cross-sectoral cooperation by (Gjerde et al., 2018) :

  • Providing common principles and objectives to help ensure that all organisations with a role in ABNJ are working toward the same overall goals;
  • Supporting the efforts of existing institutions, e.g. by enhancing cooperation and coordination, providing advice, collating and communicating information, and formulating recommendations;
  • Placing obligations upon parties to implement the treaty both directly and via their participation in competent inter-national organisations; and
  • Stimulating renewed political and financial commitment to strengthen existing efforts.


IV. Adressing climate change 

At the Paris climate conference in 2015, world leaders agreed to strengthen the global response to climate change, including by “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5°C”.

Some States have included marine components as part of their “nationally determined contributions” (NDCs) to the climate mitigation effort (Gallo et al., 2017), but climate change is a complex problem that demands an urgent and comprehen-sive response through all governance regimes and at all levels.

It is therefore imperative that climate change is integrated into the treaty through the preamble and guiding principles, as well as throughout the package, e.g.:

  • ABMTs: Recognizing the role the ocean plays as a carbon sink and protecting this function; using management tools to build resilience and protect species and ecosystems that are particularly vulnerable to climate impacts; taking into account changes in the vertical and horizontal distribu-tion of biodiversity in the design and adaptation stages of ABMTs; and pursuing management measures that account for future climate change.
  • EIAs: Requiring cumulative impacts to be taken into account, including those from climate change, deoxygenation and ocean acidification; requiring assessments to consider alter-natives to the proposed activity; providing stronger stand-ards for particularly sensitive areas.
  • Capacity building and technology transfer: Recognizing the need to build global scientific capacity to monitor climate change and ocean acidification and institutional capacity to respond in a timely way to its effects.


V. Building a fair and equitable treaty

Distribution of the benefits and externalities from activities in ABNJ is highly uneven. Ten developed countries account for 71% of high seas fishing catches (Sumaila et al., 2015) and 98% of the patents on MGRs (Blasiak et al., 2018). At the same time, the interconnected nature of the ocean means that even coun-tries remote from the high seas feel the effects of exploitation (Popova et al., 2019). This is especially concerning for devel-oping countries, whose large coastal populations often depend heavily on healthy marine ecosystems for nutrition, livelihoods and government revenues.

In drafting the treaty, the special requirements of developing countries, including Least Developed Countries (LDCs) and Small Island Developing States (SIDS), should be fully considered, in particular by:

  • Clearly linking resource access to technology transfer obligations;
  • Setting up a clearing house mechanism to facilitate coop-erative and inclusive multi-stakeholder partnerships and broker technology transfer and capacity building;
  • Taking into account the position of the majority of States who support the application of the principle of “common heritage of mankind” to MGRs and establishing effective mechanisms for benefit sharing; and
  • Providing for the designation of networks of MPAs and other ABMTs that protect biodiversity, are ecologically represent-ative, take into account the connectivity of ocean ecosys-tems, and safeguard the ecosystem services that support coastal livelihoods.


VI. Protecting marine ecosystems 

The international community has set a number of targets for marine conservation and MPA coverage [5] and protection of waters under national jurisdiction is increasing. [6]. A range of priority areas for management and protection have already been identified in ABNJ[7] but there is currently no global mechanism for the designation of MPAs or other cross-sectoral ABMTs. Several international organisations have a mandate to imple-ment sector-specific ABMTs, though they have made limited use of these tools to date. In any case, such sector-specific ABMTs cannot provide for comprehensive and coherent protection of marine ecosystems.

The new treaty can require States Parties to promote the full use of ABMTs available in existing agreements and enable the designation and implementation of cross-sectoral ABMTs at the global level. This should include fully protected marine reserves that are designed to build resilience and allow threatened marine ecosystems and species to recover. The treaty could also support broader marine spatial planning (MSP) by providing an appro-priate framework for gathering scientific knowledge and setting out the basic elements for an MSP process (Wright et al., 2018).The treaty could provide:

  • A clearly identifiable overarching mechanism for integrated policy development and coordination;
  • An obligation to establish ABMTs, including MPAs, to achieve the conservation and sustainable use of marine biological diversity in ABNJ;
  • A framework for MSP, including defining the triggers for initiating an MSP process, establishing a mandate for cooperation and coordination, and providing oversight and review;
  • Mechanisms to ensure that critical scientific knowledge is effectively and systematically communicated and integrated into policy and management decisions across sectors and geographic regions;
  • A shared set of core obligations and principles, e.g. conser-vation and sustainable use, the precautionary principle, and ecosystem-based management; and
  • Operational principles that are essential for good gover-nance, such as transparency, accountability, participation, and efficiency to enable informed decision-making.


VII. Supporting effective management of high seas fisheries 

High seas fishing can cause significant environmental impacts, not only on target species, but also on non-target species and ecosystems, in both open ocean and deep-sea environments (Clark et al., 2016; Crespo & Dunn, 2017). Fishing activities can also reduce the resilience of these systems to other stressors such as climate change. Fishing effort is growing faster on the high seas than within national jurisdictions and approximately 45% of highly migratory fish stocks are unsustainably fished (compared to 33% globally) (FAO, 2018).

The UN Fish Stocks Agreement (UNFSA) places responsibility for the management of high seas fisheries primarily with RFMOs —consensus-based organizations comprising fishing States.


The UNFSA calls for management of target stocks, associated or dependent species and species belonging to the same ecosystem. However, RFMOs have focussed almost exclusively on manage-ment of target stocks (Crespo et al., 2019) and there has been limited implementation of ecosystem-based approaches (Juan-Jordá et al., 2018). Implementation of UN General Assembly resolutions requiring protection of vulnerable marine ecosystems (VMEs) from the impacts of bottom fishing has also been slow and uneven (Gianni et al., 2016; Wright et al., 2015).

The management of high seas fisheries is a significant chal-lenge due to geographic and taxonomic gaps, lack of moni-toring, control, surveillance (MCS) and enforcement capabilities, limited data and understanding of the composition and trophic interactions in open ocean and deep-sea ecosystems, and the vertical and horizontal connectivity between them (Ban et al., 2014). All of these factors limit the ability of RFMOs and their member States to implement an ecosystem approach to fish-eries management in ABNJ. A new treaty could:

  • Provide mechanisms for increased monitoring and manage-ment of non-target species (e.g. bycatch quotas);
  • Protect important habitats for commercial fish stocks and associated ecosystems from pollution or other forms of degradation;
  • Promote the application of expansion of ABMTs for fish-eries, including dynamic management measures;
  • Improve the science for ecosystem-based approaches, including by studying the broader biological communities within which target species are found; and
  • Strengthen monitoring of vessels in the high seas, including by calling for the use of vessel tracking systems.

VIII. Reinforcing capacity and sharing marine technology

Capacity building and technology transfer play a key role in enabling developing countries to conserve and sustainably use marine resources, meaningfully participate in international fora dealing with ocean affairs, and meet their international obliga-tions to protect the marine environment.The new treaty could provide an enabling environment for capacity building and technology transfer by:

  • Clarifying and strengthening existing standards and obligations;
  • Establishing a clearing house mechanism (including, but not limited to, a web-based platform) with clear guiding principles that can catalyse capacity building, technology transfer, and cooperation between different actors;
  • Enabling the generation and exchange of information regarding existing capacity, capacity needs and priorities (e.g. through technology needs assessments), and available opportunities (including those offered by global, national, regional and sectoral organisations, as well as non-govern-mental organisations); and
  • Identifying clear institutional responsibilities, including for: assembling information on current needs; undertaking a gap analysis to identify opportunities for enhanced capacity building and technology transfer; promoting international collaboration; and developing financial mechanisms to support capacity development


IX. Putting Science at the heart of Conservation and management 

Management of natural resources relies on the collection, anal-ysis and operationalization of data as actionable and acces-sible scientific knowledge. This workflow, from data collection to knowledge transfer across the science-policy interface, determines what the “best available science” is for any given management or policy decision. Yet our knowledge of ABNJ is limited due to the high cost of sampling such diverse envi-ronments and variables at great distances from shore under extreme conditions.[8]


Conservation and sustainable use of marine biodiversity in ABNJ cannot be achieved without better structural support for science (including scientific databases), new avenues of data collection, and improved access to data and usable knowl-edge. A variety of actors already contribute to this scientific effort (Crespo et al., 2019), and there are huge opportunities for industry to play a more prominent role in data collection and sampling.

Options for improving data availability include:

  • Cross-sectoral standards for transparency that increase access to critical data streams (e.g. fisheries observer program data and vessel tracking systems);
  • Requirements to submit data to the Ocean Biogeographic Information System (OBIS), e.g. data generated during the EIA process;
  • Development of partnerships to deliver more opportunities for ocean observing; and
  • Interaction or integration of the Global Ocean Observing System’s Regional Alliances and Regional Seas organizations.

To be useful in management and policy arenas, data must not only be readily available, but it must also be comparable and interoperable. This requires the application of harmonised standards to data collection, storage and analysis. Existing inter-national institutions that address data standards[9]and provide data exchange mechanisms (e.g. OBIS) should be strengthened and supported. Any scientific body established under a new treaty could provide guidance regarding opportunities and gaps in the framework for delivering “best available science” and facil-itate coordination across regional and sectoral bodies.


X. Keeping and eye on the High Seas 

Effective monitoring, control and surveillance (MCS) is crit-ical for the success of marine conservation and management. In addition to traditional MCS mechanisms, such as on-board observers and logbooks, innovative technological tools and monitoring systems are now being developed that are set to revolutionise the way the marine environment is monitored.

Initiatives like Global Fishing Watch are utilising advanced computing techniques and public data sources, such as signals from vessels’ Automatic Identification Systems (AIS), to track fishing activity in near real-time. Many States are now contrib-uting proprietary Vessel Monitoring System (VMS) data in an effort to increase transparency and better understand and manage their fisheries resources.[10]

The negotiations provide an opportunity to facilitate the development of a more efficient and harmonised system of MCS and raise both the capacity and ambition of States. In particular, the treaty could (Cremers et al., 2019):

  • Consolidate and reinforce key MCS principles, such as trans-parency, cooperation and coordination, and reporting;
  • Provide a clearing-house mechanism with a mandate to strengthen MCS, specifying that it shall serve as a platform to share best MCS practices, exchange data on MCS activi-ties, and match capacity-building needs in relation to MCS tools;
  • Standardise the application of MCS rules and reporting across RFMOs in order to ensure best practice; and
  • Require inclusion of an MCS strategy in ABMT proposals, thereby encouraging consideration of the available techno-logical tools and institutional frameworks that can support effective implementation and compliance.
