Vast quantities of plastic waste and discarded fishing gear are accumulating on the beaches of the Seychelles, threatening the nation’s fragile ecosystems and key economic sectors, including tourism and fishing. A recent study conducted by researchers from the University of Oxford indicates that a significant portion of this pollution originates from vessels operating within or near the archipelago’s own waters.
The Aldabra Atoll, a UNESCO World Heritage site, is estimated to have accumulated more than 500 tonnes of plastic debris. Researchers project that clearing this waste would require approximately 18,000 hours of labor and cost roughly US$4.68 million. The study utilized satellite tracking data from 2018 to 2022 to simulate the drift of pollution, challenging previous assumptions that the majority of plastic debris originated from distant shores.
The findings suggest that much of the fishing gear found on Seychelles beaches originates from within the nation’s exclusive economic zone. The report highlights the role of European Union fishing vessels, which operate in the region under a long-standing agreement. A report presented to the Indian Ocean Tuna Commission noted that 76% of 214 drifting fish aggregating devices identified in the zone were linked to Spanish-owned vessels.
The Seychelles recently renewed its fishing agreement with the EU for the 2026-2030 period, with an annual payment of €5,750,000. Researchers argue that this financial arrangement is insufficient to cover the environmental and economic damages caused by the waste left behind by industrial fishing operations.
Regarding international shipping, the study identified five major lanes in the western Indian Ocean as the source of over 90% of plastic debris originating from commercial vessels. Researchers suggest that addressing this issue requires stricter enforcement of international anti-dumping regulations and improved bilateral cooperation with nations whose ships utilize these maritime routes. Proposed mitigation strategies include reducing the reliance on single-use plastic bottles on board vessels.
