Imagine waking up one morning to find that the lungs of the Earth have been appropriated for business. That the vast, ancient, breathing wilderness covering more than 70% of the planet’s surface – the source of every second breath we take, the regulator of our climate, the cradle of our food – has been carved up, zoned, auctioned and branded as an ‘economy.’ Let us not get shocked. It is already happening. It is being called the ‘blue economy.’ And on this World Ocean Day, as the United Nations invites us to “Reimagine: Beyond the World We Know, A New Relationship with Our Ocean,” we must face a disturbing truth. The loudest voices reimagining the ocean are investment bankers, port developers and government planners with trillion-dollar ambitions. Sustainability wrapped in blueThe blue economy, as conceptualised by the United Nations and multilateral institutions initially, was born of genuine concern. The World Bank and United Nations, in their foundational 2017 report The Potential of the Blue Economy, argued that oceans – carrying about 80% of global trade by volume, producing oxygen for billions, feeding hundreds of millions – must be managed as natural capital rather than exploited as a free common. They warned that around 31.4% of global fish stocks were already overfished, that illegal fishing was draining US$10–22 billion annually from the global economy, and that climate change, ocean acidification and sea-level rise were degrading the very ecosystems on which human welfare depends. UNEP articulated a similar vision – a blue economy that integrates economic growth, social equity and environmental sustainability within ecological limits, generating an estimated US$2.5 trillion annually, equivalent to the world’s seventh-largest economy while protecting the ecosystems that make this wealth possible. The UN’s Sustainable Development Goal 14, ‘Life Below Water’ gave this vision a legal and moral weight. However, these were documents that acknowledged hard truths. They spoke of the rights of small-scale fishers, Indigenous communities and coastal peoples. They demanded stronger governance, marine protected areas, and what researchers now call “safe and just” ecological limits for ocean use. But good frameworks, once released into the world, are quickly colonised by those with the most capital and the loudest lobbying voices.When ‘blue’ becomes a licence to plunderAccording to studies, the global ocean economy is projected to reach US$3 trillion by 2030, growing faster than the world economy itself. Coastal and marine tourism alone contributes about US$4.6 trillion annually, equivalent to 5.2% of global GDP. Offshore wind capacity reached 59,009 MW globally in 2023. The marine biotechnology market could expand from US$5.8 billion to US$11.7 billion by 2032. Aquaculture is projected to grow at 2% annually through 2030. Behind every one of these figures is a race for ocean space. Around 90% of global fish catches and 97% of offshore oil and gas production already occur within Exclusive Economic Zones. Shipping routes, offshore wind farms, aquaculture zones, tourism infrastructure and deep seabed mining areas compete viciously for the same stretches of sea.Also read: Commercial Shipping Project to Strategic Asset: Report Details How Great Nicobar Project Was RecastThe result, as researchers Sumaila and Villasante warn, is an “increasingly crowded ocean” where overlapping claims generate conflicts – between industrial and artisanal fishers, between conservation zones and commercial projects, between the needs of coastal communities and the appetites of corporations.Nigerian environmental thinker Nnimmo Bassey describes the outcome bluntly as ‘bluewashing’ – the deployment of sustainability language to mask what is, in practice, the extraction, privatisation and industrialisation of marine ecosystems. The absence of a universally accepted definition of the blue economy, he argues, allows governments and corporations to use the concept in ways that prioritise profit over ecological survival, displacing artisanal fishers, Indigenous peoples and coastal communities in the process. Fishing rights concentrated under corporate quota systems. Nutritious fish species diverted into fishmeal production for global aquaculture industries. Traditional livelihoods extinguished in the name of ‘sustainable development.’ It is the lived reality of millions of people on coastlines from West Africa to South Asia.The financial risks of this pattern are equally severe. A WWF–Metabolic study estimates the global ocean’s assets at a minimum of US$24 trillion – yet they are being systematically degraded. Its Baltic Sea case study found that fisheries alone could face a Value at Risk of 73%, equivalent to €1.32 billion, over fifteen years as fish stocks decline. More than US$8 trillion worth of assets worldwide are exposed to climate-related threats such as sea-level rise, extreme weather and ecosystem collapse. The blue economy, in other words, is already eating its own foundations.Blue destructionThe gap between blue economy rhetoric and reality is noticeable in some of the most consequential development projects of our time. Perhaps nowhere is the tension more plainly discernible than in India’s Great Nicobar Island. The Union government’s mega infrastructure project – estimated to cost between Rs 81,000 crore and Rs 1 lakh crore – envisions transforming this remote island in the Andaman and Nicobar archipelago into a transshipment port, international airport, township of 3.5 lakh people, and industrial hub. Located only about 40 nautical miles from the East–West international shipping route, the project is designed in the language of strategic necessity and port-led development. What it would actually destroy is staggering. According to critics, around 130 square kilometres of old-growth tropical rainforest – part of a UNESCO-recognised Biosphere Reserve – would be cleared. While official estimates suggest around 9.64 lakh trees may be felled, independent scientists estimate the figure could range between 32 lakh and 58 lakh, potentially exceeding 10 million trees if the full project footprint is considered. Galathea Bay, where the port is planned, is the most important nesting site for the Giant Leatherback Turtle in the entire northern Indian Ocean. The Nicobar megapode and saltwater crocodile face habitat annihilation. And the Shompen – one of India’s most isolated and vulnerable tribal communities, numbering only about 237 people – face effective dispossession of their ancestral land and forest, even as the government insists they will not be ‘displaced.’ The NITI Aayog’s own blue economy strategy identifies the Andaman and Nicobar waters as among India’s richest offshore fishing grounds, with significant tuna, billfish and deep-sea shrimp resources. But the same strategy emphasises ecosystem-based management, biodiversity conservation and precautionary harvesting. The contradiction between that policy philosophy and the scale of destruction proposed in the Great Nicobar project is one that official India has yet to honestly address.In the Baltic Sea, decades of over-fertilisation, overfishing and industrial expansion have pushed once-thriving cod and herring stocks to near-collapse, with cascading effects on fishing communities that have depended on these waters for generations. The WWF–Metabolic study uses this as its case study precisely because it demonstrates how environmental degradation translates, inexorably, into financial ruin, within a single planning cycle. Kerala’s ambitions and the fishworkers’ warningCloser to home, Kerala chief minister V.D. Satheesan, marking World Ocean Day this year, declared that Kerala has the potential to emerge as India’s maritime gateway and a major centre of the blue economy. With nearly 600 kilometres of coastline, the new Vizhinjam International Seaport, inland waterways and fishing harbours, the chief minister articulated a vision of port-led growth, coastal shipping, aquaculture, shipbuilding and cruise tourism – a vision of “sustainable ocean governance,” he said, that protects the ocean while generating large-scale employment. Vizhinjam is already a significant maritime investment. Kerala’s coastal economy is real and substantial. The aspiration to create dignified livelihoods from the sea is entirely legitimate. And, yet, the fishworkers’ leaders of Kerala – representing hundreds of thousands of artisanal fishing families who have worked these waters for generations – have raised urgent concerns. Their anxiety is not unfounded. Globally, blue economy projects have repeatedly prioritised industrial and corporate actors while marginalising small-scale fishers, through displacement for port development, through the loss of traditional fishing grounds to aquaculture operations, through quota systems that concentrate fishing rights under corporate control. The concentration of ocean governance in the hands of large investors, however well-intentioned, has a consistent history of eroding the food security and livelihoods of the most vulnerable coastal communities. Kerala’s blue economy ambitions must reckon seriously with this history, and with the voices of those whose lives depend on the health of the sea, not merely its profitability.The ocean we cannot afford to loseStudies say that nearly 90% of large fish populations have been depleted. About half of the world’s coral reefs have already been lost. The ocean, which produces at least half the planet’s oxygen and absorbs 30% of global CO₂ emissions, is warming, acidifying and losing biodiversity at rates without precedent in human history. Marine Protected Areas cover only about 7.5% of the world’s oceans, far below the 30% target for 2030 – a target that itself risks becoming a new arena for corporate enclosure, displacing small-scale fishers and Indigenous peoples in the name of conservation.

The fisherfolk of Kerala, the artisanal communities of West Africa, the island peoples of the Pacific, the tribal inhabitants of Great Nicobar – they are not mere stakeholders to be ‘consulted’ in blue economy planning. They are its primary custodians, and they are the first to suffer when the ocean is treated as a commodity. By 2030, ocean-based industries are expected to employ around 40 million people worldwide. That statistic, cited by the United Nations, carries a warning embedded within it – those 40 million people, and the billions who depend indirectly on the ocean, are entirely exposed to the consequences of getting this wrong.Marine spatial planning must centre the rights of small-scale fishers, women, youth and Indigenous communities. Deep seabed mining – perhaps the most reckless frontier of blue extraction – must face a moratorium until studies can seriously assess its consequences. Projects like the Great Nicobar mega-development must be subjected to genuine, independent environmental scrutiny rather than the performance of compliance. The World Ocean Day calls for serious introspection, beyond our short-term payoffs from the blue economy business. K.M.
