Along its vast coastline, India’s blue economy is expanding at speed—powered by ports, fisheries and technology, even as rising seas, storms and inequality threaten to undo it.
By Prof Ujjwal K Chowdhury | A Deep-Dive Feature on India's Coastal Economy
Before the sun lifts fully above the Bay of Bengal, the boats are already gone. In a cluster of mud-and-thatch homes at the edge of the Sundarbans — that vast, drowned forest where the Ganga surrenders itself to the sea — the women are already sorting yesterday's catch. The smell of salt and fish oil hangs over everything. A child runs barefoot across the bank. A mobile phone rings. The world has arrived, but the tide has not waited for it.
This is coastal India: ancient, adaptive, and increasingly imperilled. It is also the story of a nation trying to grow fast enough to survive what the sea is slowly taking back.
India's coastline stretches 7,516 kilometres if you count only the mainland, and considerably more once you fold in the 1,382 islands of the Andaman, Nicobar, and Lakshadweep archipelagos. Along this edge live roughly 250 million people — more than the entire population of Brazil — whose livelihoods are tied, in one way or another, to the water. They are fishermen, port workers, hotel staff, salt farmers, aquaculture entrepreneurs, mangrove honey collectors, and software engineers whose offices happen to face the sea. Together, they inhabit an economy that contributes approximately four per cent of India's GDP directly through fisheries, shipping, and tourism — and far more if you count the invisible supply chains that move through this littoral corridor every single day.
"India's coastal economy is not a sector. It is a civilisation — one that the country is only beginning to understand."
That economy is now at a turning point. Climate change, rapid industrialisation, a revolution in deep-sea technology, and a tectonic shift in global maritime trade routes are simultaneously reshaping what it means to live and work on India's shores. The story is not simple, and it is not the same on all three coasts. The west is a story of industrial muscle. The south is a story of human capital. The east is a story of painful reinvention. And threading through all three is a question that no government, no corporation, and no activist has yet fully answered: can you grow an economy and save the sea at the same time?
The Invisible Engine Running Beneath the Waves
Most Indians think of the coast as a holiday destination or, perhaps, a fishing village seen from a train window. The reality is considerably more complex. India is one of the world's top five fish-producing nations, with an annual output of roughly 195 lakh tonnes, a figure that makes seafood one of the country's most significant agricultural exports. The journey of a single prawn from a shrimp farm in coastal Andhra Pradesh to a dinner table in Tokyo is a sophisticated, multi-stage logistics operation involving feed suppliers, pond managers, processing plants, cold-chain trucks, customs agents, and container shipping lines. It is, in miniature, a portrait of what economists call a blue value chain — and India has hundreds of them running simultaneously.
Then there is the port economy. India has 12 major ports and more than 200 notified minor ones, and they handle over 95 per cent of the country's international trade by volume. When a garment made in Tiruppur reaches a wardrobe in Manchester, it has almost certainly passed through Chennai port. When an onion from Nashik reaches a kitchen in Singapore, Mundra or JNPT has handled it. The port is not merely infrastructure; it is the hinge on which India's $600 billion export ambition turns.
Beyond fish and freight, there is tourism — Goa's beach shacks and Kerala's houseboats, the diving reefs of the Andamans and the temple-towns of Tamil Nadu's Coromandel coast. India's coastal tourism industry is worth tens of thousands of crores annually. And then there is the emerging frontier: offshore wind energy, seabed mining for polymetallic nodules worth an estimated $110 billion, marine biotechnology, and ocean-based carbon capture. This is where the story of the coast is no longer about yesterday's economy, but tomorrow's life and livelihood.
Three Coasts, Three StoriesThe Western Wall: Ports, Petrochemicals, and the Price of Scale
If you wanted to understand the economic ambition of modern India, you would start on the western coast. Here, in Gujarat and Maharashtra, the coastline has been transformed over the past three decades from a fishing frontier into an industrial colossus. Gujarat alone accounts for 8.1 per cent of India's GDP, a share that has risen steadily from 6.4 per cent at the turn of the millennium. Its per capita income now sits at 160 per cent of the national average — higher even than Maharashtra's 150 per cent. The engine of this growth is not agriculture or IT services. It is the coast.
Mundra Port, operated by Adani Ports and Special Economic Zone, is now the country's largest commercial port by cargo volume. A few hours north, Kandla — officially renamed Deendayal Port — handles the bulk cargo that feeds India's oil refineries and fertiliser plants. The Jamnagar refinery complex, the world's largest single-location refinery, draws its crude through dedicated marine terminals and exports refined products from the same. In economic terms, the western coast is a fully integrated industrial ecosystem, where petroleum, chemicals, automobiles, and textiles move through purpose-built port infrastructure with a precision that rivals Rotterdam or Singapore.
Maharashtra adds financial depth to this industrial foundation. Mumbai remains India's commercial capital, and its historic port — now being reimagined as a mixed-use waterfront development — is the symbolic centre of a city whose entire identity is coastal. Jawaharlal Nehru Port, across the harbour, is the country's primary container port. And further south, the Konkan coast, with its dramatic cliffs and protected bays, is being steadily developed for tourism and fisheries.
Yet growth here has come with visible costs. The fishing communities of Gujarat's coastline — the Kharwas, the Machhis, the Vadvals — have been squeezed between industrial expansion and a regulatory system that has often prioritised cargo over community. Coastal erosion near industrial zones is measurable and documented. The creek systems around Mumbai, once among the most biodiverse in the subcontinent, have been severely degraded by decades of untreated effluents. In Ratnagiri, Maharashtra, thousands of fishermen and farmers mounted sustained protests against the proposed Nanar oil refinery, succeeding eventually in stalling it. The western coast teaches a clear lesson: scale without ecological accounting is not growth. It is borrowing from the future.
"The shrimp on your plate may have been farmed, frozen, packed, and shipped from coastal Andhra to Tokyo in less time than it took you to plan your dinner."
The Southern Mind: Brains, Backwaters, and Biodiversity
The five southern states — Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, and Telangana — together account for 30 per cent of India's GDP, and their coastlines are among the most economically and ecologically complex in Asia. This is the coast of paradoxes: some of India's most-educated fishing communities live here, alongside some of its most severe coastal erosion. The region hosts world-class ports and ancient temple-towns. It is where traditional catamaran builders and satellite engineers both call themselves children of the sea.
Kerala is perhaps the most studied coastal economy in India, not because it is the largest, but because it is the most instructive. With a literacy rate of 96.2 per cent — the highest in the country — and a fishing sector deeply integrated into local culture and cooperative economics, Kerala has built a coastal livelihood model that other states regularly send delegations to study. The backwaters of Alleppey and Kumarakom are not just tourist attractions; they are working waterways that support inland navigation, paddy farming on reclaimed polders, and a freshwater fishery that has its own distinct economy. The Vizhinjam deep-sea transshipment port, currently under construction south of Thiruvananthapuram, promises to be a game-changer — a facility deep enough to handle the world's largest container vessels, potentially pulling trans-oceanic traffic that currently bypasses India for Colombo.
Tamil Nadu's Chennai is already a major port, but the state's coastal economy extends far beyond it. The Gulf of Mannar, separating Tamil Nadu from Sri Lanka, hosts one of India's richest marine biospheres — a chain of coral reefs, seagrass meadows, and mangrove patches that support both artisanal fisheries and a growing marine tourism economy. Thoothukudi is a major industrial port, while Nagapattinam and Karaikal are fishing hubs with deep cultural identities shaped by the 2004 Indian Ocean tsunami, which killed over 10,000 people in Tamil Nadu alone.
The 2004 tsunami remains the south's defining coastal trauma. It arrived without warning at dawn on December 26, erasing villages in minutes. The reconstruction period that followed revealed something important: communities with higher social capital — better education, stronger women's self-help groups, more responsive local governance — recovered faster and more completely. This lesson has since been absorbed into disaster risk frameworks, and Tamil Nadu and Kerala now have some of India's most sophisticated coastal disaster management systems.
Andhra Pradesh contributes enormously to India's seafood exports through its massive shrimp aquaculture industry, particularly in the Krishna and Godavari delta districts. Visakhapatnam is a steel and petroleum port, but it also handles pharmaceutical exports from the Hyderabad hinterland. The coast here is industrial but not entirely so — the Coringa Wildlife Sanctuary near Kakinada protects one of India's largest mangrove forests, a natural buffer between cyclone-prone sea and densely-populated deltaic farmland.
The Eastern Comeback: Corridors, Cyclones, and Careful Optimism
The eastern coast tells the most complicated story. From the Sundarbans of West Bengal, sweeping south through Odisha and Andhra Pradesh to the northern tip of Tamil Nadu, this is the coastline most battered by cyclones, most challenged by poverty, and most in need of both investment and protection. It is also the coast with perhaps the greatest unrealised potential.
West Bengal was once India's industrial heartland. In 1960-61, it accounted for 10.5 per cent of national GDP. By 2023-24, that figure had fallen to 5.6 per cent — a relative decline that mirrors the broader deindustrialisation of the state after the 1970s. Kolkata, once the second city of the British Empire, is no longer a port of global consequence. The Haldia dock complex handles some petroleum and fertiliser traffic, but it is a pale shadow of what this coast once was.
The Sundarbans, however, are a world unto themselves. This 10,000-square-kilometre tidal mangrove delta — split between India and Bangladesh — is a UNESCO World Heritage Site, home to the Bengal tiger, the Irrawaddy dolphin, and roughly four million people who make their living from fishing, crab collection, and honey harvesting from the world's most dangerous forest. Cyclone Amphan in 2020 caused losses exceeding Rs 1 lakh crore in West Bengal alone, and much of the damage fell on these delta communities. The Sundarbans are sinking — literally. Ghoramara Island has lost more than half its land area to the sea in the last four decades. Sagar Island, where hundreds of thousands of pilgrims gather each January for Makar Sankranti, is measurably shrinking.
Odisha has reversed its decline through mineral wealth and ambitious infrastructure. Its per capita income has climbed from 55.8 per cent of the national average in 2000-01 to 88.5 per cent today. Paradip Port, handling iron ore, coal, and fertilisers, is growing rapidly. The state has also dramatically improved its cyclone resilience: in 1999, the super-cyclone killed nearly 10,000 people. When Cyclone Fani, equally powerful, struck in 2019, fewer than 100 lives were lost — a testament to evacuation systems, improved housing codes, and community preparedness that the world took notice of.
The most ambitious plan for the eastern coast is the East Coast Economic Corridor, India's first coastal economic corridor, stretching 2,500 kilometres from Kolkata to Kanyakumari. Its first phase, the Visakhapatnam-Chennai Industrial Corridor, is backed by $500 million from the Asian Development Bank and aims to link mineral-rich Odisha and Andhra Pradesh with Tamil Nadu's manufacturing base. The goal is not just to attract industry but to reduce India's notoriously high logistics costs — currently 13-14 per cent of GDP, against a global average closer to 8 per cent. Cheaper, faster movement of goods through this corridor could make India's exports significantly more competitive.
"The Sundarbans are sinking. Ghoramara Island has lost half its land in four decades. This is not a forecast. It is already happening."
Neighbours in the Same WaterBangladesh: Resilience Carved from Catastrophe
Any serious account of India's eastern coast must cross the border into Bangladesh. The two countries share the Sundarbans, the Bay of Bengal's cyclone belt, and a fisheries ecology that does not respect national boundaries. Bangladesh's ocean economy contributes approximately 3.33 per cent of its GDP — a figure that understates the sector's social importance given that fisheries alone provide 60 per cent of the country's animal protein intake and the sector supports the livelihoods of roughly 30 million people.
Chittagong Port, renamed Chattogram, is the country's economic lifeline — handling 92 per cent of import-export cargo and 98 per cent of containerised trade. In 2025, it achieved a historic throughput of 3.4 million TEUs, driven largely by the garment sector, which accounts for 84 per cent of Bangladesh's export earnings. The ready-made garment industry is coastal in a peculiar sense: its goods move through a single port chokepoint, making the country extraordinarily vulnerable to any disruption at that gateway.
Bangladesh's disaster risk management is among the most celebrated in the world. In 1970, Cyclone Bhola killed an estimated 500,000 people — one of the deadliest natural disasters in recorded history. Today, Bangladesh's network of cyclone shelters, early warning systems, and trained community volunteers has reduced cyclone mortality by more than 99 per cent relative to those devastating mid-century events. The country has done this on a fraction of the budget that rich nations spend on comparable protections. It is a model that India's eastern coast should study closely.
Sri Lanka: Lessons from a Hub that Nearly Sank
Sri Lanka's relationship with the sea is total — it is an island, surrounded on all sides. The Port of Colombo is one of the Indian Ocean's great transshipment hubs, a place where container ships from Europe, East Africa, and East Asia cross paths. In 2024, Sri Lanka attracted 2.05 million tourist arrivals — a 38 per cent increase over the previous year — with India remaining the single largest source market, accounting for over 20 per cent of visitors. Tourism earnings exceeded $3 billion, a figure critical to the country's recovery from its 2022 economic meltdown, when foreign reserves fell to a catastrophic $50 million and fuel queues stretched for kilometres.
The Sri Lankan crisis — driven by unsustainable debt, a sudden ban on chemical fertilisers that devastated agriculture, and the catastrophic loss of tourism revenue during the pandemic — is a cautionary tale about the fragility of coastal economies over-dependent on a few sectors. The country's recovery has been managed through an IMF programme worth $3 billion and a historic restructuring of $17 billion in external debt. The new government has prioritised anti-corruption reforms and targeted investment in port modernisation and marine tourism. Sri Lanka's eight UNESCO World Heritage Sites and extraordinary marine biodiversity — from the blue whales of Mirissa to the reefs of Pigeon Island — remain assets that, if managed wisely, can sustain the economy for generations.
The Laws That Protect — and the Loopholes That Don'tUNCLOS, the Paris Agreement, and India's Shifting CRZ
The ocean has a constitution. It is called UNCLOS — the United Nations Convention on the Law of the Sea — and it was adopted in 1982 after nine years of negotiation. UNCLOS divides the sea into zones: the territorial sea (12 nautical miles from shore, under sovereign control), the contiguous zone, and the Exclusive Economic Zone or EEZ (200 nautical miles, where the coastal state has sovereign rights over resources). For India, the EEZ covers 2.3 million square kilometres — an enormous maritime territory rich in fish, minerals, and as-yet-unexploited energy resources.
UNCLOS does not directly address climate change, but its provisions requiring the protection and preservation of the marine environment are increasingly being interpreted to cover ocean warming and acidification. The Paris Agreement, meanwhile, obligates signatory nations — including India — to limit greenhouse gas emissions in ways that will reduce sea level rise and cyclone intensity. India has committed to net-zero emissions by 2070 and has pledged that 50 per cent of its electricity will come from renewable sources by 2030. For coastal communities, the pace of this transition is not an abstract policy question. It is an existential one.
Domestically, the most contested piece of coastal law is the Coastal Regulation Zone notification. The CRZ rules govern what can be built, farmed, or mined within specified distances from the high-tide line. The 2011 notification established a No Development Zone of 200 metres in rural coastal areas and froze urban construction density at 1991 levels, prioritising conservation. The 2019 notification reversed much of this, reducing the NDZ to 50 metres in densely populated rural areas and unlocking floor space index norms in urban coastal areas. Developers celebrated. Environmentalists called it a systematic dismantling of protection.
Crucially, the 2019 rules removed the 'Hazard Line' — a demarcation based on predicted sea-level rise and tidal ingress — from regulatory planning, relegating it to an informative tool rather than a planning constraint. This means that hotels, roads, and residential buildings can be constructed in areas that hydrological models identify as likely to be submerged within decades. Critics argue this is not development; it is the subsidisation of future disaster.
India also has the Environment Protection Act of 1986 and the Wildlife Protection Act of 1972, both of which have provisions relevant to coastal ecosystems. The Forest Rights Act of 2006 has been used by coastal communities to assert rights over mangrove areas and traditional fishing grounds. But the gap between law on paper and enforcement on the ground remains wide enough to drive a trawler through. Illegal sand mining along Kerala's beaches has caused severe erosion. Industrial effluents continue to reach the sea in violation of the Water Prevention and Control of Pollution Act. The problem is rarely the absence of law. It is the presence of indifference.
Technology at the Water's EdgeFrom GPS Buoys to Deep-Sea Submarines: The Digital Transformation
The fisherman from Dakhinpara who once read the sky to predict weather now gets a satellite forecast on his mobile phone. This is not a small change. It is the difference between a boat that sets out into a cyclone and one that stays safely at home. The Indian National Centre for Ocean Information Services disseminates Potential Fishing Zone advisories via SMS and satellite, telling fishermen exactly where ocean temperatures and currents suggest fish are most likely to be concentrated. The result is less fuel burned, fewer empty nets, and more time at home with family.
But this is just the visible surface of a deeper technological revolution. At the institutional level, the National Fisheries Digital Platform has created digital identities for over 26 lakh coastal stakeholders, linking them to formal credit, crop insurance, and government schemes. The platform acts as a single window through which a fisherman in Mangaluru can apply for a loan, register his boat, and claim disaster relief — services that once required days of travel to government offices. Simultaneously, 'Blue Port' pilots are being developed in collaboration with the UN Food and Agriculture Organisation at Vanakbara in Diu, Jakhau in Gujarat, and Karaikal in Puducherry, deploying IoT sensors, 5G connectivity, and solar-powered cold chains to transform old fishing harbours into smart, export-ready hubs.
For the high seas, India has placed a significant bet on its Deep Ocean Mission — a Rs 4,077 crore programme that is simultaneously the country's most ambitious scientific expedition and its most strategic economic play. The mission's centrepiece is MATSYA 6000, a manned submersible designed to dive 6,000 metres beneath the surface. Its pressure vessel is a sphere of titanium alloy with 80-millimetre walls, built to withstand 600 times atmospheric pressure, welded using electron beam technology developed by ISRO after 700 trials. In 2025, MATSYA successfully dove to 5,000 metres in the Andaman Sea and returned with cobalt-rich polymetallic nodules — early proof of a seabed that India's ocean scientists believe holds 380 million metric tonnes of mineral wealth, including copper, nickel, cobalt, and manganese critical to green energy technologies.
In the private sector, a new generation of startups is rewriting the economics of aquaculture. NatureDots uses AI and satellite imagery to monitor coastal pond conditions in real time, detecting early signs of disease outbreaks that can destroy entire shrimp crops. Aquaconnect provides precision feeding and health analytics that reduce the cost and environmental footprint of aquaculture operations. GreenGrahi converts food waste into insect-based protein for fish feed, reducing the industry's dependence on wild-caught fish meal — a practice that depletes the very ocean stocks that coastal communities depend on. These companies are small now. But they represent the direction of travel.
"MATSYA 6000 dove to 5,000 metres and returned with mineral nodules worth billions. India's next economic frontier may lie two kilometres below the sea."
The Unfinished Story of Coastal JusticeWomen, Work, and the Economy Nobody Counts
Walk into any fish market on any Indian coast and you will find women. They sort the catch, set the prices, manage the credit, and run the micro-enterprises that convert raw fish into packaged product. Studies across coastal states consistently find that women control between 60 and 80 per cent of post-harvest fisheries activity. Yet they are counted in almost no official economic data. They do not own the boats. They rarely own the land. Their labour is invisible to GDP calculators and ignored by most credit systems.
This is a social injustice, but it is also an economic mistake. Self-help groups of coastal women in Kerala and Tamil Nadu have demonstrated that when women are given access to revolving credit funds and collective marketing channels, the productivity of entire fishing communities rises. In Odisha, women trained in mangrove afforestation through state and NGO programmes have become the primary guardians of coastal forests that protect their own villages from storms. In Bangladesh, women's early warning networks have been instrumental in saving lives during cyclones. The evidence is overwhelming: investing in coastal women is one of the highest-return strategies available to any coastal economy.
What Activists, Citizens, Government, and Business Must Do
The future of India's coast is not predetermined. It will be shaped by choices made now — by governments, corporations, communities, and individuals. What is required is not a single grand plan but a coordinated set of actions, sustained over decades, that treat the coast as what it actually is: a living system that produces enormous value precisely because it is alive.
For governments, the most urgent task is to restore the Hazard Line to regulatory planning — not as bureaucratic obstruction but as common sense protection for the people who live in flood-prone areas. The Sagarmala programme has rightly focused on port-led development, but it needs a parallel ecological accounting system that measures what is lost when a mangrove is cleared or a creek is filled. The MISHTI scheme — India's mangrove restoration programme — must be funded at scale and monitored rigorously, with a mandatory 3:1 replanting ratio enforced when coastal development displaces natural vegetation. State coastal zone management authorities, many of which exist largely on paper, need real budgets, real staff, and real enforcement powers.
For the private sector, the model to emulate is not the extractive one but the regenerative one. The Godrej Group voluntarily protected 750 hectares of mangroves in Mumbai decades before any law required it — and that forest now provides measurable flood protection to millions of residents. The port industry needs to accelerate the transition to Green Port standards: electric handling equipment, zero-discharge wastewater systems, and marine litter monitoring programmes. For businesses in fisheries and aquaculture, investing in blockchain-based traceability systems is not just an ethical choice; it is a commercial necessity, as the European Union and US are moving toward mandatory seafood traceability requirements that will exclude non-compliant suppliers.
For activists and civil society, the role is to ensure that the voices of coastal communities are present in the rooms where decisions are made. The protests against the Sterlite copper plant in Thoothukudi, which led to its eventual shutdown after 13 people were killed by police fire in 2018, demonstrated both the courage of coastal communities and the extreme price they sometimes pay for that courage. More recently, fisherfolk protests over the construction of Vizhinjam port in Kerala raised legitimate concerns about displacement and compensation that were only partially addressed. Documenting violations, filing environmental impact complaints, litigating in the National Green Tribunal, and building coalitions across caste and community lines: these are the tools of coastal activism, and they have proven effective.
For citizens living far from the coast, the connection is closer than it feels. Every piece of single-use plastic discarded in a city eventually reaches a river, and every river reaches the sea. Consumer choices — buying sustainably certified seafood, refusing microplastic-heavy cosmetics, supporting ecotourism operators with genuine community benefit-sharing — transmit real signals to coastal economies. The Versova beach cleanup in Mumbai, led by lawyer Afroz Shah, mobilised over 1,000 volunteers over 85 weeks and removed more than 20 million kilograms of plastic, earning a United Nations Champions of the Earth award. It began with one person who was offended by the state of a beach he loved. That is a model for citizenship, not just environmentalism.
The Tide That Does Not Wait
There is a word in Bengali — 'nadibandhu' — that means 'friend of the river'. On the Sundarbans islands, fishermen use it to describe someone who truly understands the water: its moods, its generosity, its violence. India needs to become a nadibandhu to its coast — not exploiting it or romanticising it, but genuinely understanding it and taking responsibility for it.
The numbers support urgency. Sea levels along India's coast are rising at between 1.3 and 3.2 millimetres per year, with some segments rising faster. Cyclone frequency in the Bay of Bengal has increased, and cyclone intensity — the category of storms — has risen sharply in the Arabian Sea, which historically produced fewer severe storms. Fish catch volumes in inshore waters are declining as overfishing and ocean warming displace fish populations into deeper, cooler waters. Groundwater in coastal districts of Gujarat, Andhra Pradesh, and Tamil Nadu is becoming increasingly saline as sea intrusion advances.
Against this, India has genuine assets. Its scientific institutions — the National Institute of Oceanography, the Centre for Marine Living Resources and Ecology, the Indian National Centre for Ocean Information Services — are world-class. Its fisheries cooperatives in Kerala are models studied internationally. Its disaster management systems, built painstakingly after the tragedies of 1999 and 2004, have saved hundreds of thousands of lives. Its blue economy startups are innovating at pace. Its diaspora of coastal engineers, marine biologists, and maritime lawyers brings global knowledge back to Indian shores.
The question is whether these assets can be mobilised fast enough, and in coordination with each other, to build a coastal economy that is genuinely sustainable — one that feeds its people, trades with the world, explores the deep sea, and still leaves the mangroves standing.
India's target of becoming a $5 trillion economy by the late 2020s will not be met from the hinterland alone. The ports must work. The fisheries must thrive. The tourism coasts must be clean enough to attract visitors and honest enough to share the benefits with the communities that live there. The offshore wind turbines must spin. The MATSYA submersible must return from the deep with knowledge and resources that belong to all Indians, not just the few.
"Every river reaches the sea. Every coastal decision eventually comes back to the citizen who made it — or failed to."
As the boats return at evening to harbours from Saurashtra to the Sundarbans, carrying the day's catch and the day's stories, the sea behind them holds its counsel. It does not care about GDP targets or election cycles or corporate quarterly results. It cares only about balance. And it will enforce that balance, one way or another — by storm or by surrender, by crisis or by wisdom.
India still has the chance to choose wisdom. The tide is not yet fully in. But it is coming.
