VICTORIA, Seychelles, February 3 (IPS) - The world is entering a decisive period for the future of the ocean. With the High Seas Treaty coming into force and meaningful progress being made on the World Trade Organization Agreement on Fisheries Subsidies, global momentum for stronger marine governance is building. Yet, new pressures linked to the push for deep-sea mining — the extraction of minerals from seabed thousands of meters below the ocean surface — threaten to undermine these gains. To safeguard progress, global decision-making will have to keep pace with such emerging risks. In this context, Africa will host several global discussions in 2026, including those that will shape the ocean’s future, with a series of opportunities for leadership starting with the African Union Summit in February to the Our Ocean Conference in Mombasa, Kenya in June.

As two long-standing friends of the ocean who have witnessed both its fragility and its generosity, we view the ongoing discussions on deep-sea mining as a moment that calls for careful, science-based and inclusive reflection. This is especially true in a region of the world where people depend on a healthy ocean for livelihoods, culture, spirituality and climate resilience, and where more than 30 per cent of Africans, roughly 200 million people, rely on fish as their main source of animal protein.

These concerns are particularly relevant to the Western Indian Ocean (WIO), one of the most biodiverse marine regions in the world, with endemism as high as 22 per cent yet at the convergence of multiple environmental stresses. Coral reefs and mangrove forests are deteriorating, while illegal, unreported and unregulated fishing, and sand mining put additional pressure on already fragile ecosystems. The lasting impacts of the 2020 Wakashio oil spill in Mauritius show how quickly harm to the ocean can ripple across communities. In such a fragile setting, the introduction of a new extractive industry demands the highest level of scrutiny.

In the face of these emerging challenges, Seychelles has an important role to play. For decades, it has demonstrated leadership in championing the blue economy and protecting marine ecosystems. Early ratification of the BBNJ Treaty, along with advocacy for High Seas marine protected areas such as the Saya de Malha Bank, has positioned the country as a respected voice for responsible ocean governance. If deep-sea mining begins in the Pacific, the Indian Ocean is likely to follow, including on the mid-Indian Ridge east of Seychelles’ EEZ and within the Southern Indian Ocean Fisheries agreement region. Catalyzing a new wave of continental leadership on deep-sea protection would advance a vision of ocean stewardship grounded in equity and sustainability. A precautionary pause on deep-sea mining would give concrete expression to that vision.

Scientific research continues to underline this need for caution. Deep-sea mining would have an irreversible impact on seabed ecosystems and species. And recent studies of the midwater zone, where waste plumes from deep-sea mining would spread, show that mining particles could reduce the nutritional quality of the natural food supply for zooplankton by up to ten times. This would decrease food quality and trigger effects that move through the food web, ultimately affecting larger species and the overall health of the ocean millions of people rely on. In an environment where more than 99.99 percent of the deep ocean floor has yet to be explored or directly observed, introducing large scale industrial activity could cause damage that cannot be undone.

The economic risks for the region are equally significant. The Western Indian Ocean’s natural assets have been conservatively valued at 333.8 billion dollars, making the ocean one of the region’s most important sources of long-term wealth. Within this, fisheries represent the single largest asset and a cornerstone of economic resilience. The region generates about 4.8 percent of the global fish catch, roughly 4.5 million tonnes each year, underscoring how many economies and communities depend on healthy stocks. In Seychelles and across the region, tuna fisheries in particular underpin national revenue, employment and food security. Undermining the sustainability of fisheries could therefore not only threaten livelihoods but also diminish long-term economic opportunity.

The accelerating push for deep-sea mining activities also raises concerns about repeating historic patterns seen in other extractive sectors across Africa. The uneven distribution of benefits from land-based resource exploitation has shown how easily local communities can be left with environmental impacts while external actors capture most of the value. Without strong governance frameworks that ensure fair participation and transparent decision-making, current deep-sea mining models risk following a similar trajectory, privileging short-term economic gain for multinational corporations over regional priorities.

Finally, the argument that deep-sea mining is necessary for the renewable energy transition is also increasingly at odds with current evidence. Rapid advances in recycling technologies, circular economy approaches, and alternative materials are already reducing the projected demand for minerals from new extractions. These pathways can support the global transition without the need to industrialize one of the least understood parts of the planet. The United Nations Environment Programme has also made clear in their 2022 report that “there is currently no foreseeable way in which investment into deep-sea mining activities can be viewed as consistent with the Sustainable Blue Economy Finance Principles”.

In parallel, African-led nature-positive initiatives are demonstrating how ocean resources can be managed in ways that support both people and the environment. Initiatives such as the Great Blue Wall aim to create connected networks of protected and restored marine areas that strengthen biodiversity, climate resilience and community wellbeing across the WIO region. These efforts demonstrate what a regenerative blue economy can look like in practice. Preserving these gains requires ensuring that new activities do not compromise the progress already made.

Across the continent, young leaders, civil society and scientific institutions are calling for greater accountability in decisions that shape our collective future. Their message is clear: long-term wellbeing for everyone must come before short-term gains for a select few. This call also echoes a growing movement worldwide, with more than 40 countries now supporting a pause on deep-sea mining, including France, Fiji, Chile and Mexico. A precautionary pause on deep-sea mining is not a rejection of economic progress, but a commitment to sound science, inclusive dialogue and responsible stewardship. We are hopeful that countries in Africa and elsewhere in the world will hear this call and secure the future of the ocean for generations to come.
