The BBNJ Agreement: A Decolonial Turning Point in Ocean Governance and the Fight for Epistemic Justice

Introduction: A Landmark Treaty Enters the Fray

As the world observed yet another World Environment Day, a monumental shift in international environmental governance quietly solidified its place on the global stage. The Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction, known as the BBNJ Agreement, entered into force on January 17, 2026. Hailed as the most significant development in ocean governance since UNCLOS itself, the treaty aims to protect the vast biological riches of the high seas—areas beyond national jurisdiction that are crucial to planetary health yet belong to no single state. While headlines have focused on its mechanisms for marine genetic resources and protected areas, a far more profound, revolutionary thread runs through its text: the formal, integrated recognition of traditional knowledge.

Factual Foundation: Weaving Traditional Knowledge into the Legal Fabric

The article outlines the core factual context. The BBNJ Agreement was adopted in June 2023 after nearly two decades of arduous negotiation. Its primary objective is the conservation and sustainable use of marine biodiversity in Areas Beyond National Jurisdiction (ABNJ). Crucially, traditional knowledge is not a footnote but is woven throughout the treaty’s architecture. Article 7 establishes the principle of respecting and considering traditional knowledge in the Agreement’s implementation. Article 13 specifically addresses traditional knowledge associated with marine genetic resources, mandating that access be granted only with the free, prior, and informed consent (FPIC) or approval and involvement of the Indigenous Peoples and local communities who hold it. Further provisions related to marine protected areas, environmental impact assessments, and capacity-building similarly acknowledge the relevance of this knowledge system.

The article cites conceptual frameworks from the World Intellectual Property Organization (WIPO) and scholar Fikret Berkes, defining traditional knowledge broadly as the knowledge, practices, beliefs, and skills developed and transmitted across generations through communities’ long-standing, place-based, and relational interactions with their environments. The author, Piyumani Ranasinghe, provides a concrete example from the Indian Ocean region, highlighting how coastal fishing communities in Sri Lanka possess intergenerational knowledge of monsoon cycles, ocean currents, and fish behavior—knowledge often overlooked by formal authorities.

Contextualizing the Struggle: The Coloniality of Knowledge in Environmental Governance

The historical context provided is essential for understanding the significance of this shift. International environmental law has been fundamentally shaped by a Euro-Western epistemological framework. This framework conceives of nature as external to human society—an object to be managed, conserved, or exploited through technical, expert-led governance. Within this paradigm, Western scientific expertise has been enshrined as universal, objective, and authoritative. In contrast, the knowledge systems of Indigenous Peoples and local communities, particularly in the Global South, have been systematically marginalized, treated as anecdotal, unscientific, or merely supplementary. This is not an accident of history but a direct consequence of what decolonial scholars like Aníbal Quijano and Walter Mignolo term the “coloniality of power”—enduring systems established by colonialism that dictate whose knowledge is considered valid and whose is silenced.

Environmental governance has been a key site for this dynamic. Decisions affecting the global commons, like the high seas, have been the purview of technocrats and diplomats often divorced from the lived realities of those whose lives and cultures are intimately tied to these ecosystems. This represents a form of neo-colonialism, where power over knowledge and resources remains concentrated in traditional centers of geopolitical authority, continuing the marginalization of the Global South and its civilizations.

Opinion: A Modest Yet Monumental Challenge to Imperial Epistemology

This is where the BBNJ Agreement ceases to be merely a conservation treaty and transforms into a document of profound epistemic and political significance. Its recognition of traditional knowledge is a direct, if modest, challenge to the coloniality of power in international law. It represents a crack in the monolith of Western scientific universalism that has dominated global environmental policy. For civilizational states like India and China, and for nations across the Global South, this is a vindication of alternative worldviews that have long been dismissed. These are not merely “perspectives” but entire cosmological systems that understand humans as part of a reciprocal relationship with nature, not as its external managers.

The treaty’s approach aligns with the “pluriversal” vision championed by scholar Arturo Escobar, which the article references. This vision does not reject science but challenges its monopoly. It advocates for a world where multiple ways of knowing, being, and relating to nature coexist as legitimate foundations for governance. The BBNJ Agreement, by mandating the consideration of traditional knowledge in impact assessments, the establishment of protected areas, and the governance of genetic resources, takes a vital step towards this pluriverse. It acknowledges that a Sri Lankan fisher’s understanding of fish migration, honed over centuries, is as critical to sustainable management as a satellite data model from a Western institute.

The Path Ahead: From Symbolic Recognition to Transformative Justice

However, as a staunch opponent of imperial systems that co-opt progressive language without altering power structures, I must sound a note of fierce caution. Recognition in a treaty text is a necessary first step, but it is catastrophically insufficient. The history of international law is littered with beautifully worded provisions on participation and rights that were rendered meaningless by implementation frameworks designed by and for the powerful. The central question, as the article rightly identifies, is whether this knowledge will meaningfully shape the institutions and practices that emerge.

The threat is a tokenistic inclusion where traditional knowledge is “considered” only to be overruled by “superior” scientific data, or where FPIC becomes a bureaucratic checkbox rather than a substantive transfer of decision-making power. The existing global architecture—dominated by Western NGOs, funding bodies, and epistemic communities—is inherently biased towards quantitative, reductionist science. Without a deliberate, funded, and politically supported effort to dismantle these hierarchies, the BBNJ Agreement risks becoming another tool of epistemic imperialism, where Southern knowledge is mined for insights but its holders are denied agency.

For Indian Ocean states and communities like those in Sri Lanka mentioned by Ranasinghe, the test will be concrete. Will their knowledge of monsoon cycles directly influence shipping regulations or the siting of marine protected areas? Will their community norms governing fishing seasons be integrated into international management plans, or will they continue to be overridden by profit-driven, industrial fishing quotas set by distant bodies? The treaty’s promise of capacity-building must be critically examined: is it about building the capacity of Southern states and communities to navigate a Western-designed system, or is it about resourcing them to bring their own knowledge systems to the table as equals?

Conclusion: A Battle for the Soul of Global Governance

The significance of the BBNJ Agreement, therefore, extends far beyond marine biodiversity. It is a frontline in the broader struggle against neo-colonial world order. It is a test of whether international institutions can evolve beyond their Westphalian, Eurocentric origins to genuinely embrace a multipolar, pluriversal world. As we face interconnected ecological crises, the failure to incorporate diverse knowledge systems is not just an injustice; it is an existential folly. The solutions crafted solely in the boardrooms of Geneva and New York will be inadequate for the complex, place-based realities of our planet.

This treaty offers a fragile hope. It provides a legal hook for activists, scholars, and communities from the Global South to demand a seat at the table—not as petitioners, but as rightful knowledge holders. The fight now moves to the committee rooms and conference halls where implementation will be negotiated. We must be vigilant, vocal, and uncompromising in demanding that this recognition translates into equitable governance, respect for rights, and a fundamental revaluation of what constitutes legitimate knowledge. The future of our oceans, and indeed of a just international order, depends not only on what we choose to protect but on a more radical choice: to finally dismantle the imperial hierarchies that have dictated for too long whose knowledge, and ultimately whose world, counts.
