Blue Economy Rising: The Caribbean Is Finally Building an Ocean Economy It Owns
The Caribbean Sea produces up to a quarter of the world's ocean economy from one per cent of its surface. A run of new institutions, finance vehicles, and research partnerships across 2025 and 2026 is starting to build what the region needs to capture it.
Key Points
- ✓ The Caribbean Sea generates 14 to 27 per cent of the global ocean economy from one per cent of the world's ocean surface. Most of that value goes uncaptured because the blue economy was never treated as a formal economic driver, so the skills, data, and finance to build on it were never developed.
- ✓ The Caribbean Development Bank approved US$226.7 million for climate action in 2025, more than double its 2024 figure, and is finalising a US$200 million regional blue economy programme for 2026 to fund ocean ventures and create marine-sector jobs.
- ✓ The University of Guyana's marine institute will produce around 500 marine professionals over four years, from marine biologists to port engineers and maritime lawyers, building the specialist workforce the region's ocean industries require.
- ✓ Working projects already show the model: a UWI spin-off fuelling cars on sargassum in Barbados, a Bahamas farm growing coral 50 times faster than the ocean, and a Grenada coastal master plan mapping blue growth across fisheries, aquaculture, and blue biotechnology.
No comparable body of water on the planet is so economically dense. The Commonwealth estimates that between 14 and 27 per cent of the global ocean economy originates from the Caribbean Sea, which covers roughly one per cent of the world's ocean surface. Fisheries, coastal tourism, marine transport, and a growing marine renewable and biotechnology sector all draw on that water. Most of it has never been measured, financed, or governed by the region that depends on it.
That is starting to change. Across 2025 and 2026, Caribbean governments, universities, and development banks have moved on the blue economy with a coordination the region has not shown before. The Caribbean Development Bank more than doubled its annual climate finance and is building a US$200 million programme aimed squarely at ocean projects. The University of Guyana opened the region's most ambitious marine training institute. Barbados assembled a finance stack built specifically to fund ocean ventures. Grenada wrote a master plan for blue growth across its entire coastline.
The scale still sits well below the region's potential, and the reason is structural. For decades the blue economy was not formally recognised as an economic driver in most Caribbean states, so the skills pipelines, the seabed data, and the dedicated finance that any ocean industry runs on were never built. Those are the three foundations now going in. None works without the others, and the projects already running show what they unlock once they are in place.
Why the Caribbean has captured so little of its ocean wealth
The blue economy covers any economic activity that takes place in the ocean or draws on its resources: fishing and aquaculture, coastal and marine tourism, marine renewable energy, and marine transport. A joint paper from the Caribbean Development Bank and the United Nations Development Programme named those four as the industries most suitable for targeted investment in the region. The analytical case has existed for years. What stopped it translating into industry was that most Caribbean governments never classified the ocean as a sector worth building institutions around.
The cost of that omission runs through the region's economy. Caribbean island states pay around US$0.30 per kilowatt-hour for electricity, among the highest rates in the hemisphere, largely because they burn imported diesel that the surrounding ocean could help displace. Fish stocks are managed from data sets that sit in separate silos. Coastlines that carry the tourism economy are eroding without the mapping needed to defend them. Each is an ocean problem with an ocean solution, and each solution needs trained specialists, reliable data, and capital structured for projects that take years to pay back.
Those three foundations, skills, data, and finance, are what the past two years have begun to supply across Guyana, Barbados, Grenada, and the wider OECS. The projects already operating show what they unlock.
Guyana is building the region's marine workforce
An ocean economy runs on people who can do the work, and the Caribbean has never trained enough of them. The University of Guyana is closing that gap directly. Its Institute for Marine and Riverine Ecologies and Economies, launched at the Berbice campus, studies marine and freshwater systems together, a fit for a country that calls itself the Land of Many Waters.
Vice Chancellor Professor Paloma Mohamed Martin set the institute's target at around 500 graduates over four years across marine biology, maritime law, port management, marine engineering, port security, and aqua-biotechnology. The same surveys she cited put the workforce gap in Guyana's marine and maritime industries at between 2,000 and 6,000 people, so the institute is a start rather than a complete answer. The curriculum, running from the 2024 to 2025 academic year, staffs every role an ocean economy needs rather than the one or two a single department might pick.
The training is built with industry rather than in isolation. The university is developing the programmes alongside Maersk and other maritime and environmental partners, designed to feed real jobs in shipping, logistics, marine engineering, and coastal management. The institute is one node in a wider build-out at the University of Guyana, which has stood up research institutes across climate, food security, and coastal monitoring as oil revenue reshapes the country. If the model holds, it becomes a template that Barbados, Trinidad, and others can adapt to grow their own pipelines.
Seabed and fisheries data: the layer that makes projects bankable
Trained people still cannot site a marine energy project on a seabed no one has mapped, or finance a fishery no one can measure. Data is the foundation that turns skills and capital into projects, and the Caribbean has had the least of it.
Several initiatives are now filling specific gaps. The European Marine Observation and Data Network ran a three-day seabed-mapping workshop in Anguilla in April 2026 to bring regional actors into shared mapping standards. The Seabed 2030 project has incorporated new datasets that strengthen Caribbean coverage. On the fisheries side, the Food and Agriculture Organization held a 2025 session on using GIS mapping, satellite remote sensing, and artificial intelligence to make Caribbean fisheries more sustainable. Each fills a different blind spot: where the seabed lies, what shape it takes, and what is being caught above it.
The gap they are closing is wide. The Caribbean Fishery Management Council oversees more commercial and recreational species than any other council in the United States, yet the data needed to assess those stocks comes from sources siloed from one another. Shared data standards and AI-assisted stock assessment are now treated by policymakers as a precondition for any credible blue economy strategy, building the informational floor that ocean governance has never stood on.
Barbados is engineering the finance that ocean projects need
Ocean ventures carry long payback periods and environmental uncertainty that commercial lenders price as too risky to touch, which is why dedicated finance is the third foundation. Barbados has built more of it than anywhere else in the region. The island created a Ministry of Maritime Affairs and the Blue Economy in 2018, joining the Seychelles as one of the only countries in the world with a ministry dedicated to the ocean economy. Its exclusive economic zone is 430 times the size of the island itself, which is why its government calls Barbados a large ocean state.
The finance came in layers. In September 2022, the Government of Barbados, The Nature Conservancy, and the Inter-American Development Bank completed a US$150 million debt conversion that cut the country's debt burden and generated US$50 million for marine conservation over 15 years, channelled through an independent trust. The associated marine spatial plan commits Barbados to protecting up to 30 per cent of its ocean space, roughly 55,000 square kilometres. A debt-for-nature swap turns the cost of conservation into a saving on debt servicing, which is how a heavily indebted small state finances ocean protection it could not otherwise afford.
The newest layer is the Blue Green Bank, capitalised through the Green Climate Fund, USAID, and the Government of Barbados, with structural support from the Rockefeller Foundation. Barbados estimates that achieving climate resilience will cost around US$2 billion, equivalent to 40 per cent of its GDP, and the bank exists to keep that finance flowing to local projects. At the regional level, the Caribbean Development Bank's US$226.7 million in 2025 climate approvals, more than double its 2024 total, and its forthcoming US$200 million blue economy programme provide the macro-finance backdrop against which national vehicles operate. The same logic, that an island short on capital can engineer ocean finance from debt restructuring and multilateral funds, recurs in the wider question of who pays for coastal resilience once the engineering is proven.
What the foundations already unlock
The clearest argument for building skills, data, and finance is what happens where they already exist. In Barbados, a University of the West Indies spin-off is running cars on sargassum, converting the seaweed that fouls Caribbean beaches, together with rum distillery wastewater, into compressed biogas fuel. It is a marine waste stream turned into transport energy by trained researchers working from a university base, exactly the combination the three foundations are meant to produce.
In the Bahamas, a land-based farm is growing coral 50 times faster than the ocean using microfragmentation and assisted evolution, and it raised the first Series A investment ever made in coral restoration. That deal is a signal that ocean restoration can attract commercial capital once the science and the finance structures line up. Both projects depend on the same inputs: specialist skills, measurable results, and investors willing to back a marine venture.
Grenada shows the planning end of the same shift. Its Blue Growth Coastal Master Plan, developed with the World Bank, is an integrated spatial plan that identifies blue growth opportunities across fisheries and aquaculture, aquaponics, blue biotechnology, and marine research. Within the OECS, that work sits alongside the Caribbean Regional Oceanscape Project, a collaboration between the OECS Commission and the World Bank focused on strengthening the resilience of coastal and marine resources and putting regional blue-growth policy into practice. Grenada, a country that brands itself the Spice of the Caribbean on the strength of its nutmeg exports, is mapping a future in which its ocean carries comparable economic weight.
What the Caribbean blue economy could look like
Put the foundations together and the shape of a mature regional ocean economy comes into view. Marine graduates trained in Guyana and, in time, in their own national institutions staff ports, fisheries agencies, and marine ventures across the region. Seabed maps and shared fisheries data let those ventures raise capital on measured results rather than promises. Dedicated finance from vehicles like the Blue Green Bank and the CDB's blue economy programme closes deals that commercial lenders would not have touched a decade earlier. Ocean thermal energy, which Caribbean researchers have mapped as viable across multiple islands with cold deep water close to shore, offers a path off the imported diesel that keeps regional electricity prices among the world's highest.
The most concrete sign of where this is heading came in June 2026, when Barbados Prime Minister Mia Mottley concluded talks in Toronto with Canadian Prime Minister Mark Carney and proposed a joint Canada-Barbados maritime research hub linking universities in both countries. The proposal pairs Canada's coastline expertise with Barbados's status as a large ocean state, and signals a region that intends to do ocean science in partnership, on its own terms. The asset has always been there. For the first time, the region is building the skills, the data, and the finance to turn it into an industry it owns.

Frequently Asked Questions
What is the blue economy in the Caribbean?
The blue economy refers to economic activity that takes place in the ocean or relies on its resources, including fisheries and aquaculture, coastal and marine tourism, marine renewable energy, and marine transport. In the Caribbean it carries unusual weight: the Commonwealth estimates that 14 to 27 per cent of the global ocean economy originates from the Caribbean Sea, even though the sea covers only about one per cent of the world's ocean surface.
Why has the Caribbean captured so little value from its ocean?
For decades the blue economy was not formally recognised as an economic driver in most Caribbean states, so the specialist workforce, seabed and fisheries data, and dedicated finance that any ocean industry depends on were never built. Recent initiatives across Guyana, Barbados, Grenada, and the wider OECS are now putting those foundations in place, which is what allows ocean projects to move from concept to investment.
How much is the Caribbean Development Bank investing in the blue economy?
The Caribbean Development Bank approved US$226.7 million for climate action in 2025, its highest annual climate total and more than double the US$101.5 million committed in 2024. For 2026 the bank is finalising a separate US$200 million regional blue economy programme aimed at protecting ocean resources and creating marine-sector jobs.
What is the University of Guyana's marine institute?
The University of Guyana's Institute for Marine and Riverine Ecologies and Economies, based at the Berbice campus, is a training and research institution covering marine and freshwater systems together. It offers degrees spanning marine biology, port management, marine engineering, maritime law, and aqua-biotechnology, and aims to produce around 500 marine professionals within four years to help close a national workforce gap estimated at 2,000 to 6,000 people.
What is a debt-for-nature swap and how has Barbados used one?
A debt-for-nature swap restructures a country's debt in exchange for a commitment to fund conservation, turning debt relief into protected-area financing. In 2022, Barbados, The Nature Conservancy, and the Inter-American Development Bank completed a US$150 million debt conversion that reduced the country's debt burden and generated US$50 million for marine conservation over 15 years, supporting a plan to protect up to 30 per cent of its ocean space.
What is Grenada's Blue Growth Coastal Master Plan?
Grenada's Blue Growth Coastal Master Plan, developed with the World Bank, is an integrated spatial plan for the island's marine and coastal environments and the economic activities they can sustainably support. It identifies blue growth opportunities across fisheries and aquaculture, aquaponics, blue biotechnology, and marine research, and forms part of wider OECS efforts including the Caribbean Regional Oceanscape Project.
