A major new report released at the 11th Our Ocean Conference in Mombasa is warning that the global push to protect 30 per cent of the ocean by 2030 risks stalling unless governments and funders move quickly to invest in the workforce, governance systems, and local partnerships needed to make marine protection function in practice, not just on paper.

The report, Closing the Implementation Gap: Capacity Development for Effective Marine 30×30, was produced by the Adrienne Arsht Community-Based Resilience Solutions Initiative at the Smithsonian Tropical Research Institute and released on 16 June 2026. It offers what its authors describe as a comprehensive global assessment of the human, institutional, financial, and technological systems required to make marine protected areas (MPAs) and other area-based conservation measures actually deliver lasting outcomes, rather than existing only as designations on a map.

Designation Is Not Delivery

The report’s central finding cuts against a common assumption in ocean conservation circles: that announcing new protected areas is itself a marker of progress. Instead, the authors find that while countries continue to designate new MPAs at a steady pace, many still lack the workforce, governance structures, long-term financing, and local coordination required to make those protections meaningful.

Dr. Vanessa Constant, Associate Director for the Arsht Resilience Initiative at the Smithsonian Tropical Research Institute, frames the shift in thinking the report is calling for: “It is insufficient for marine 30×30 to just be a designation challenge. It has to become an implementation challenge, backed by complementary investment in people, institutions, and long-term stewardship so that protected areas become more than lines on a map.”

The numbers underline the urgency. Nations committed to protecting 30 per cent of the world’s oceans by 2030 under the Kunming-Montreal Global Biodiversity Framework, agreed in December 2022. Since then, marine protection has expanded steadily: designated MPAs now cover 9.8 per cent of the global ocean as of April 2026, up from 8.4 per cent in 2024. But a full 20 per cent of ocean area still needs protection to hit the spatial target, and the report’s authors stress that protection alone will not be enough. At least half of existing MPAs remain unimplemented or operationally ineffective, a gap the report calls the defining challenge of the next four years.

Two Foundations: Local Context and Coordination

The report’s findings draw on stakeholder engagement conducted between April and October 2025 with governments, scientists, Indigenous Peoples, local communities, NGOs, and financial actors across three regions: Southeast Asia, Latin America and the Caribbean, and the Western Indian Ocean.

From that process, the authors identify two foundational requirements for closing the implementation gap: regional contextualisation and effective coordination. Marine conservation, the report argues, cannot rely on one-size-fits-all approaches. Each region needs governance models grounded in local realities, supported by long-term partnerships, cross-sector collaboration, and structured peer-to-peer learning between regions facing similar challenges.

Building on that foundation, the report identifies six further priority areas requiring urgent investment: governance and policy continuity, long-term and locally accessible funding, inclusive stakeholder engagement, data and technology accessibility, socio-ecological integration, and public communication and storytelling.

The Technology Gap on the Ground

One of the report’s sharper warnings concerns a widening mismatch between the pace of marine technology development and the operational realities facing the people meant to use it. Satellite monitoring and AI-driven analytics are advancing rapidly, but many coastal regions still lack the basic technical training, digital literacy, or access to actionable data systems needed to put those tools to work. Without addressing that gap, the report suggests, technological progress in monitoring could end up widening rather than narrowing the implementation divide.

The report also pushes for a shift in how MPAs are talked about publicly, away from framing them as restrictions on activity and toward presenting them as a shared economic, cultural, and environmental value proposition tied directly to livelihoods, food security, and long-term prosperity.

A Systems Problem, Not Just a Funding Problem

Rocky Sanchez Tirona, Managing Director of Regional Programs at Rare, situates the findings within a broader framing: “This is ultimately a systems challenge. Effectively protecting 30% of the ocean will depend not only on political will, but on sustained investment in the people, institutions, relationships, and regional and local leadership needed to make conservation endure.”

That framing positions the report as a counterpoint to conservation narratives that measure success primarily through percentage-of-ocean-protected figures. The report’s authors argue that the real measure of progress is whether protections are genuinely enforced and effective at sustaining marine biodiversity, not simply whether a designation has been filed.

Released at a Symbolic Moment

The timing of the report’s release is deliberate. It lands during the 11th Our Ocean Conference in Mombasa, the first edition of the conference held on African soil, where governments, scientists, civil society organisations, and investors have gathered specifically to push ocean commitments from rhetoric toward delivery.

The report points to examples already emerging across multiple regions, where local organisations, Indigenous leaders, and innovative funding partnerships are demonstrating what effective capacity development for marine conservation looks like in practice. The challenge now, the authors note, is scaling those examples fast enough to keep pace with the scale of global ambition.
