The Blue Economy: An Untapped Engine of Growth and Where southern Mediterranean Stands

For decades, the world's oceans and seas were treated largely as backdrops to economic activity useful for shipping goods and catching fish, but rarely recognized as an economic sector in their own right. That thinking has shifted decisively. Today, the "blue economy", encompassing everything from fisheries and aquaculture to shipping, coastal tourism, offshore energy, and marine biotechnology is increasingly viewed as one of the most promising frontiers for sustainable growth, particularly for coastal nations seeking to diversify beyond traditional industries.

The numbers help explain why. Across Africa alone, ocean-linked industries already support nearly 50 million jobs and contribute an estimated $300 billion annually to the continent's economy, with vastly more potential still untapped. Africa's blue-economy footprint is staggering: more than 38 of its 54 nations hold sovereign rights over adjacent ocean territory, and the continent's exclusive economic zones span over 13 million square kilometres, backed by roughly 47,000 kilometres of coastline. Given the demographic profile of Africa's median age compared with Europe, labour-intensive blue sectors such as fisheries, maritime transport, and shipping could become major sources of youth employment in the coming years.

Why the Blue Economy Matters Now

Several factors have propelled this sector from a niche talking point to a mainstream policy priority. First, food security: fisheries and aquaculture remain a primary protein source for hundreds of millions of coastal inhabitants, and demand continues to climb alongside population growth. Second, climate resilience: healthy marine ecosystems, including mangroves, seagrass beds, and coral reefs absorb carbon, buffer coastlines against storms, and support biodiversity, making their protection both an economic and an environmental imperative. Third, economic diversification: countries over-reliant on oil, gas, or monocrop agriculture are increasingly turning to ports, shipping, marine tourism, and renewable ocean energy to build more resilient economies. Finally, geopolitics: control over maritime trade routes, undersea data cables, and offshore resources has become a strategic consideration for governments worldwide, not merely an economic one.

None of this is automatic, however. Realizing the blue economy's potential demands governance, financing, and infrastructure resources that many countries, including several in Africa, are still working to build. A recent investigation into Nigeria's dedicated Blue Economy Ministry, for instance, found it operating with only a small fraction of the funding needed to address the sector's estimated 72-trillion-naira financing gap (about $45–$50 billion US), a stark illustration of how far ambition can outpace on-the-ground investment.

The situation in southern Mediterranean

The region flanks the Mediterranean, one of the world's busiest and most ecologically significant seas, while Morocco and Mauritania also open onto the Atlantic. Egypt alone controls the Suez Canal, arguably the single most important maritime chokepoint for global trade. This geography alone grants the region outsized relevance in any discussion of ocean-based economic growth.

Morocco has emerged as one of the region's more active players, advancing the WestMED initiative, a Mediterranean-wide effort launched in 2017 that brings together five EU countries and five North African partner states (Algeria, Libya, Mauritania, Morocco, and Tunisia) to coordinate sustainable blue-growth strategies. Morocco was also notably the country whose ratification pushed the UN's High Seas Treaty (the Biodiversity Beyond National Jurisdiction Agreement) past the threshold required for it to enter into force, a milestone reached in January 2026. Rabat has also invested heavily in expanding its fishing and aquaculture sectors along both its Mediterranean and Atlantic coasts.

Tunisia has directed significant attention toward sustainable fisheries management through programs such as MEDFISHTUN, an EU-backed initiative that promotes sustainable governance of the country's fish and aquaculture resources. Given the centrality of small-scale fishing communities to Tunisia's coastal economy, this support directly affects livelihoods, not merely macroeconomic aggregates.

Algeria has likewise received EU support aimed specifically at strengthening its fisheries and aquaculture sectors, as part of a broader regional push to modernize marine-resource management through joint action rather than isolated efforts.

Beyond the Suez Canal's outsized role in its blue economy, Egypt has been partnering internationally on multi-year programs (extending through 2027) aimed at strengthening nature conservation and sustainable resource management along its coastlines. This accompanies continued investment in its fisheries sector and Red Sea tourism, one of the country's most valuable and most climate-exposed economic assets.

Libya, despite years of political instability, remains a participant in regional frameworks such as WestMED and continues at least on paper to be part of Mediterranean-wide fisheries and marine governance efforts, though its enforcement and implementation capacity lags well behind its neighbours.

The Challenges Ahead

For all its momentum, North Africa's blue economy faces significant structural headwinds. Overfishing and illegal, unreported, and unregulated (IUU) fishing continues to strain Mediterranean fish stocks, a concern so serious that the UN's Food and Agriculture Organization has made ecosystem-based fisheries management a central regional priority through its Blue Transformation Roadmap, which runs to 2030. Marine pollution, coastal urbanization, and the pressures of climate change, including coastal subsidence increasingly documented in cities such as Alexandria add further complexity. Financing remains another persistent bottleneck: across the continent, blue economy ministries and agencies are frequently tasked with delivering ambitious national strategies without commensurate budgets, a mismatch that underscores just how underfunded even dedicated government bodies can be relative to the scale of the opportunity.

Looking Forward with Clear Eyes on What Still Stands in the Way

The momentum is real, but it would be a mistake to read it as evidence that the hard problems are close to being solved. Regional platforms such as the Union for the Mediterranean's Sustainable Blue Economy initiative, EU-backed programs like BlueInvest Africa, whose 2026 edition featured startups from Egypt, Morocco, and Tunisia pitching to international investors, and continent-wide efforts like the Great Blue Wall Initiative all signal a growing recognition that the sea is not merely a resource to extract, but a system that requires active stewardship if it is to keep yielding economic dividends. Recognition, however, is not the same as delivery.

Most of these platforms remain heavier on dialogue, pilot projects, and matchmaking events than on the large-scale, long-term financing the sector actually needs. Startup pitch competitions and stakeholder forums are useful for building networks and surfacing ideas, but they rarely close the gap between a national blue economy strategy on paper and the infrastructure, monitoring systems, and enforcement capacity required to make it real. That gap shows up starkly elsewhere on the continent, Nigeria's dedicated blue economy ministry, for instance, has been funded at a small fraction of what officials themselves say is required, and there is little reason to assume North African institutions are immune to the same mismatch between ambition and budget.

There are also harder structural constraints that no summit or investment forum can resolve on its own. Political instability continues to limit what countries like Libya can realistically implement, regardless of which regional frameworks they formally join. Overfishing and illegal fishing pressures in the Mediterranean are the product of decades of weak enforcement across multiple jurisdictions, not something a single initiative can reverse quickly. Coastal cities such as Alexandria face physical, slow-moving threats like land subsidence that sit largely outside the scope of blue economy programming altogether, yet directly undermine the coastal infrastructure that sector depends on. And regional cooperation, while improving, still runs up against differing national priorities, uneven administrative capacity, and financing structures that favor short project cycles over the sustained investment that ecosystem restoration and fisheries management actually require.

None of this erases the genuine progress underway, but it does mean the path forward is narrower and more uncertain than the language of summits and partnerships sometimes suggests. For North Africa with its Mediterranean and Atlantic coastlines, a critical global shipping chokepoint in the Suez Canal, and coastal populations whose livelihoods depend directly on marine health getting the balance right is not optional; it is fundamental to the region's long-term economic future. But getting there will likely depend less on the next platform or pledge, and more on whether governments can turn existing commitments into sustained funding, consistent enforcement, and institutions capable of outlasting the political cycles that have undermined similar efforts elsewhere on the continent.
