Around 2.4 billion people live within 100 km (62 mi.) of a shoreline, including roughly one billion within 10 km (6.2 mi.). This narrow band of land, about 5% of the inhabited world, generates an estimated [30–50%](https://www.weforum.org/publications/the-regenerative-blue-economy-pathways-to-prosperity/) of global GDP. It contains many of our fastest-growing cities, ports, energy systems, tourism economies, fisheries, and water infrastructure. In this small sliver of the planet, the foundations of a new blue economy are already being laid, once set, they will be difficult to change. We have a narrow window in which to decide what kind of economy will emerge from the ocean. More than three billion people depend on the ocean for their livelihoods. Yet the ocean economy, valued in the trillions, is steadily eroding the ecosystems that make this activity possible. Fish stocks are under pressure. Coral reefs are approaching catastrophic thresholds. Mangroves, seagrasses, and wetlands that protect communities from storms and rising seas continue to disappear. Without deliberate intervention, this blue economy will simply default to the familiar extractive model that has already depleted so much of the natural world. But we have an opportunity to take a different path, to shape it instead around a more resilient and equitable form of prosperity. The world must do more than simply slowing the depletion of our oceans. Instead, a net positive, regenerative, blue economy is needed. One that sets a higher standard: economic activity must give back more than it takes and help to rebuild the natural and social capital on which it depends. This requires a different model of growth. Established industries such as shipping, ports, and fisheries need managed transitions that reduce pollution, decarbonize operations, rebuild stocks, and redirect harmful subsidies. Expanding sectors—including offshore renewables, aquaculture, and coastal tourism—must integrate ecosystem health and community benefit into their business models. This shift can unlock a new generation of companies focused on restoration, blue biotechnology, and ocean data, which create value by improving the health and resilience of marine systems. The good news is that we already know that this approach pays. [Research suggests](https://www.undp.org/nature/blog/nature-hiring) that a nature-positive economy could create more than three times as many jobs as business as usual, while investment in ecosystem restoration can generate nearly four times as many jobs as investment in oil and gas. As populations grow and AI reshapes labor markets, we need to be far more deliberate about the kinds of economic activity we encourage. Regenerative businesses offer a rare triple dividend: creating jobs, restoring critical natural systems, and accelerating the climate transition. The opportunity is substantial, but regeneration will not emerge from thousands of disconnected projects and initiatives. Oceans function as systems, but our governance remains divided by ministries, sectors, permits, and political boundaries. We need to manage whole seascapes: connecting coastlines, watersheds, nearshore ecosystems and the people and industries that share them. Marine spatial planning can expose trade-offs, account for cumulative impacts and establish where development belongs, where restoration must take priority, and where activity should not proceed. This governance must place Indigenous Peoples and local communities at its center. They are often the most experienced stewards of coastal ecosystems yet remain excluded from the decisions and capital that shape them. The Bird’s Head Seascape in Indonesia shows what a better model can achieve. Across 225,000 sq. km (over 86,800 sq. mi.), traditional community rights over land and coastal waters have been embedded in conservation planning [since the early 2000s](https://reports.weforum.org/docs/WEF%5FThe%5FRegenerative%5FBlue%5FEconomy%5F2026.pdf). Local and government authority has been connected, and tourism revenues help finance conservation and ecosystem protection. A network of marine protected areas now covers more than 52,000 sq. km (over 20,000 sq. mi.). Community-led tourism has diversified incomes, while former “bomb fishers” have been trained as coral gardeners. Ecological recovery, livelihoods, and local authority reinforce one another because they were designed not as separate entities, but as a single interconnected system. We now need global financial and entrepreneurial architecture to step up to take such models to scale. Public and philanthropic capital can reduce early risks; blue bonds, blended finance, and debt-for-nature swaps can mobilize larger pools of investment. Dedicated financing windows, patient capital, technical assistance, and venture-building support can help coastal entrepreneurs and cooperatives grow viable businesses. Technology and AI can lower the cost of monitoring, verification, and coordination, provided they strengthen good governance rather than substitute for it. The next chapter of the blue economy will be judged by more than the wealth extracted from the ocean. Its true measure will be the fish stocks rebuilt, coastlines protected, jobs created, communities strengthened, and natural systems restored. The future of our societies is increasingly tied to the sea, and our prosperity will depend on learning to give back more than we take.
