Global policy, local authority: Why the ocean’s future will be decided beyond the project level

This is part of a 6-article series. You’re reading Part 5. Here, you can find Part 4.

Over the past four articles, this series has moved from principle to practice: from Indigenous stewardship as a foundation for ocean governance, to the evolution of blue finance, to the governance systems that shape authority, and finally to place-based case studies across five very different ocean and river systems.

Across those cases, a consistent pattern emerged. Where Indigenous or customary governance institutions are recognized as authorities rather than stakeholders, ocean interventions endure. Where they are sidelined, even well-funded initiatives remain fragile.

This raises a final, unavoidable question: what happens when local governance realities collide with global policy frameworks?

Because while oceans are lived, stewarded, and governed locally, the rules that increasingly shape them are being negotiated elsewhere — through multilateral treaties, global conferences, and international institutions whose decisions reverberate across coastlines and river basins worldwide.

Why global policy now matters more than ever

The scale and urgency of ocean degradation have pushed governance upward. Plastics pollution, climate impacts, biodiversity loss, and high-seas exploitation do not respect borders. As a result, global policy processes now play a decisive role in setting norms, allocating authority, and shaping financial flows.

Yet global frameworks face a persistent tension: they are designed to be universal, while ocean stewardship is inherently place-based.

Too often, global agreements assume that implementation will occur through state-centric systems that inadequately recognize Indigenous authority, customary governance, and community stewardship. This creates a structural disconnect between global ambition and local legitimacy.

If left unaddressed, this disconnect risks scaling governance failures rather than solutions.

The INC Plastics Treaty: A test case for inclusive ocean governance

The negotiations toward a global plastics treaty represent one of the most consequential ocean governance processes of the decade. For the first time, the international community is attempting to address plastic pollution across the full lifecycle — from production to disposal — through a binding global instrument.

The treaty’s ambition is notable, but its governance architecture remains unsettled and its ultimate conclusion uncertain.  

At stake is not only how plastics are regulated, but who has authority to define solutions.

Many Indigenous and riverine communities live at the frontlines of plastic pollution, yet their roles in treaty design have often been peripheral. Technical discussions around polymers, waste streams, and extended producer responsibility risk crowding out questions of stewardship, livelihoods, and local governance.

If the plastics treaty is to succeed, it must move beyond a purely technocratic model and:

• Recognize Indigenous communities as rights-holders, not merely implementation partners
• Embed consent and participation into national action plans
• Protect Indigenous data sovereignty in monitoring and reporting systems
• Ensure that financing mechanisms flow to stewardship institutions, not only national agencies

Otherwise, the treaty may reproduce a familiar pattern: ambitious global rules with weak local traction.

The UN Ocean Conference and COP processes: Visibility without authority?

Global ocean governance increasingly unfolds through high-profile convenings — the UN Ocean Conference, climate COPs, biodiversity summits — where commitments are announced, coalitions formed, and funding pledged.

These spaces are valuable for agenda-setting. They are far less effective at redistributing authority.

Indigenous participation has increased in visibility, but visibility does not equal power. Too often, Indigenous knowledge is showcased while decision-making remains centralized within states, development banks, and international organizations.

The risk is performative inclusion: Indigenous voices present in panels but absent from rule-making.

For global conferences to translate into durable ocean outcomes, they must move beyond pledges and toward governance reform, including:

• Institutionalized Indigenous representation in negotiation processes
• Recognition of customary governance in national implementation pathways
• Safeguards ensuring FPIC applies to globally driven initiatives
• Financing commitments tied to governance outcomes, not just project outputs

Without these shifts, global conferences risk becoming echo chambers of ambition disconnected from local authority.

High-seas governance: The limits of state-centric models

The high seas present perhaps the starkest governance challenge. By definition, they lie beyond national jurisdiction, yet they are increasingly targeted for conservation, carbon sequestration, and resource use.

The emerging high-seas governance regime remains largely state-centric, negotiated among governments with limited pathways for Indigenous or community participation.

This creates a paradox. Many Indigenous Nations possess ocean-going knowledge systems, migratory species relationships, and cosmologies that extend far beyond modern borders. Yet their governance roles are largely absent from high-seas decision-making.

As conservation and finance move into these spaces, the absence of Indigenous authority risks repeating past mistakes at planetary scale.

A more legitimate approach would:

• Recognize Indigenous knowledge as relevant beyond territorial waters
• Integrate Indigenous governance into scientific and advisory structures
• Ensure benefit-sharing reflects historical stewardship, not legal proximity alone
• Avoid treating the high seas as an empty governance space

Without such reforms, high-seas governance may achieve legal order without ecological or social legitimacy.

Global rules, local consequences

Across these policy arenas, a common pattern is visible.

Global frameworks tend to prioritize efficiency, scalability, and legal uniformity—often at the expense of Indigenous governance systems grounded in relational accountability and stewardship. Indigenous governance systems prioritize legitimacy and long-term stewardship.

These approaches are not incompatible — but they are rarely aligned by default.

When global policy fails to account for Indigenous authority, the consequences are predictable:

• Resistance during implementation
• Governance fragmentation
• Loss of trust
• Weakened ecological outcomes

Conversely, when global rules create space for Indigenous governance, they gain durability — not despite complexity, but because of it.

From global commitments to grounded governance

The next phase of ocean governance will be defined less by new treaties than by how existing ones are implemented.

This requires a shift in mindset from:

• Consultation to shared authority
• Project delivery to governance reform
• Symbolic inclusion to institutionalized power

For policymakers, financiers, and multilateral institutions, the question is no longer whether Indigenous stewardship matters.

It is whether global frameworks are willing to change in order to reflect it.

A final turn toward measurement and meaning

This brings the series to its final analytical frontier.

If global policy frameworks set the rules, and governance determines legitimacy, then measurement determines meaning.

What we choose to measure — and who defines those metrics — shapes how success is understood, rewarded, and replicated.

The final article in this series will explore that nexus directly: how science, data systems, monitoring frameworks, and Indigenous knowledge interact to guide ocean decision-making — and how misalignment at this level can undermine even the most ambitious policy and finance efforts.

Because in the end, the future of the ocean will be shaped not only by what we promise globally, but by what we choose to count, value, and govern together.
