Thirty Per Cent of an Ocean
Seychelles has 455 square kilometres of land and an exclusive economic zone of about 1.4 million. In 2016 it restructured US$21.6 million of sovereign debt owed to Paris Club creditors on the condition that it protect thirty per cent of that ocean, and in March 2020 it finished the job — ten years ahead of the deadline the rest of the world would later set itself.
The whole of Seychelles is 455 square kilometres of land — about four-fifths of the Isle of Man, spread across an archipelago that takes a week to cross by boat. The sea it governs is about 1.4 million square kilometres, which is roughly three thousand times as much water as ground. Nearly all of the country is ocean, and the ocean is most of what the country has to sell. Foreign fleets buy licences to fish it. The cannery on the edge of Victoria processes their catch and is the largest private employer in the islands. Port Victoria is one of the main tuna transhipment points in the Indian Ocean, and on a working morning the quay is stacked with brailer nets and refrigerated containers while, a kilometre inland, the market sells the reef fish that the domestic boats brought in.
By 2015 that ocean was almost entirely unprotected — something in the order of 0.04 per cent of the exclusive economic zone had any conservation designation at all. Five years later the figure was thirty per cent. What happened in between was not a donation, a treaty or an aid programme. It was a debt restructuring with a conservation clause in it, and the clause had a deadline.
What was actually swapped
In 2016, after several years of negotiation brokered by The Nature Conservancy, Seychelles bought back US$21.6 million of its sovereign debt owed to Paris Club creditors — principally Belgium, France, Italy and the United Kingdom — at a discount, financed by a mixture of impact capital and grant money raised by the Conservancy. South Africa's participation made it the first buyback of this kind in which a creditor from the global South took part. What made it a swap rather than a refinancing is where the repayments went: instead of leaving the country, a portion of the debt service was redirected in local currency into the Seychelles Conservation and Climate Adaptation Trust, a domestic public-private body set up in 2015 and known as SeyCCAT. In exchange the government committed to producing a marine spatial plan covering the entire exclusive economic zone and to designating thirty per cent of it as protected by 2020.
The first blue bond
Two years later the same machinery was used to raise new money. In October 2018 Seychelles issued the world's first sovereign blue bond: US$15 million, ten-year maturity, a 6.5 per cent coupon, placed with three American institutional investors — Calvert Impact Capital, Nuveen and Prudential Financial. On its own a small island state would not have been able to borrow at that price for that purpose. What made it work was credit enhancement from outside: a US$5 million partial guarantee from the World Bank and a US$5 million concessional loan from the Global Environment Facility to cover part of the interest, which between them brought the effective cost to the Seychelles treasury down to about 2.8 per cent. The proceeds were divided between a grants fund administered by SeyCCAT and an investment fund at the Development Bank of Seychelles lending into fisheries businesses.
Nothing here was given away. The debt was moved, the condition was written into the contract, and a country of not much more than a hundred thousand people took on the policing of an ocean about the size of Peru.
Thirty per cent, in two gazettes
The marine spatial planning process began in 2014 and ran over the whole 1.4 million square kilometres, which had never been mapped for anything other than fishing effort. Protection was gazetted in two phases. The first, in February 2018, covered the waters around the Aldabra group and a large block in the outer islands. The second, on 26 March 2020, completed the commitment and brought the total to roughly 410,000 square kilometres. It is not one uniform designation. Zone 1 — about 203,000 square kilometres, or fifteen per cent of the EEZ — is high-protection, no extractive use, and covers the Aldabra Group, Bird Island, D'Arros Atoll, the stretch from D'Arros to Poivre, and the southern Amirantes. Zone 2 is the same area again at medium protection, where fishing and other commercial activity continue under new rules. The Kunming-Montreal framework that committed the world to protecting thirty per cent of the ocean was agreed in December 2022. Seychelles had got there two years and nine months earlier.
The half that is not a no-take zone
It is worth being precise about what Zone 2 means, because thirty per cent is often quoted as though all of it were closed water. Half of the protected area explicitly leaves the working ocean working, and the working ocean here is industrial tuna. Purse seiners, mostly European-flagged, fish Seychelles waters under a partnership agreement with the EU that is renegotiated periodically and pays licence fees into the budget. Indian Ocean yellowfin has been assessed as overfished by the Indian Ocean Tuna Commission for over a decade, and the commission — a body of coastal states and distant-water fishing nations with very different interests — has repeatedly failed to agree a rebuilding plan that holds. None of that is inside Seychelles' gift to fix. A zone drawn on a chart does not change the stock assessment for a species that crosses the whole ocean, and a coastguard sized for a country of this population cannot watch 1.4 million square kilometres by eye. What the plan did buy was the legal standing to say where things may and may not happen, which is a precondition for enforcement rather than a substitute for it.
The gate, the boat and the warden
The older Seychellois conservation model is still doing most of the visible work, and it is much less abstract. The Vallée de Mai on Praslin charges SCR 450 to walk through nineteen hectares of palm forest, and half of every ticket is spent eleven hundred kilometres away on Aldabra — an atoll with about 100,000 giant tortoises on it, the largest population anywhere on earth, no paying visitors to speak of, and a research station that has to be supplied by ship. Both sites are run by the Seychelles Islands Foundation, a public trust created in 1979, and the arrangement is a straightforward cross-subsidy: the accessible World Heritage site pays for the inaccessible one. Cousin Island works the same way at smaller scale. It was bought outright in 1968, when the Seychelles warbler was down to twenty-six birds living on it and nowhere else; the coconut plantation was removed, the native vegetation came back, the warbler now numbers in the thousands across several islands, and the landing fee pays the wardens who walk you round.
The honest assessment of the financial engineering is that it worked and that it was small. Seychelles made every payment on schedule and delivered the designation ahead of the deadline, which is a better record than most conditional finance can show, and the template has since been scaled far beyond anything attempted here — Belize in 2021, Ecuador for the Galápagos in 2023, Gabon in the same year, each an order of magnitude larger. But US$21.6 million of restructured debt and a US$15 million bond do not fund the running of a marine protected area the size of a continental country. Designation is a one-off act; patrol vessels, satellite monitoring subscriptions, rangers and boat fuel recur every year, and the grant fund those deals created disburses a few million dollars annually against that. Seychelles solved the political problem of committing to protect its ocean by attaching it to a debt contract. It has not yet solved the ordinary problem of paying for it, which is why the gate money at a palm forest on Praslin still matters as much as the bond.
