India’s maritime legacy dates back to the Indus Valley civilisation, when its ports connected the subcontinent to the wider world. Today, as India charts its rise as a global economic power, the seas remain central to that journey. The government’s Maritime India Vision 2047 seeks to mobilise ₹80 lakh crore in investments and create 1.5 crore jobs over the next two decades. Union minister Sarbananda Sonowal, speaking at the India Maritime Week 2025, described it as a plan to transform ports, shipping, and inland waterways into a world-class ecosystem aligned with the goal of Viksit Bharat.
Control over ports and sea lanes has long shaped the balance of global power, and India’s maritime future must be viewed in that light. Nearly 95% of India’s trade by volume moves through the seas, making its ports not just gateways of commerce but pillars of economic and strategic security. As the world’s trade routes shift towards the Indo-Pacific, India’s vast 7,500 km coastline and growing port network give it a natural advantage — if it can harness them efficiently. The challenge lies in translating geography into competitiveness: modernising ports, strengthening last-mile connectivity, and integrating them into global supply chains. In an era when logistics defines growth, India’s maritime ambition is both an economic necessity and a geopolitical imperative.

Shifting balance in Indo-Pacific
India’s maritime push cannot be viewed in isolation from the shifting geopolitics of the Indo-Pacific. The seas that carry its trade are also arenas of strategic competition. Initiatives such as the Security and Growth for All in the Region (SAGAR) doctrine, partnerships through the QUAD, and India’s growing engagement with the Indian Ocean Rim Association (IORA) highlight the effort to balance China’s expanding influence through its Belt and Road ports network.
From Chabahar in Iran to Sabang in Indonesia, India’s ‘blue diplomacy’ is aimed at securing sea lanes, diversifying energy routes, and building coalitions that preserve freedom of navigation. A credible maritime policy must therefore blend infrastructure with strategy — combining economic integration with regional influence.
Integrating ports with national logistics grid
The government’s strategy is to integrate ports into a unified National Logistics Grid, linking maritime infrastructure to industrial corridors, freight rail networks, and highways. This coordinated approach could reduce logistics costs, which remain among the highest in Asia. Analysts note that such integration — if executed well — can bring down India’s logistics costs from 14% of GDP to single digits, making exports more competitive.
Technology will be the backbone of India’s logistics integration. Digital platforms like the National Logistics Data Bank (NLDB) and Port Community System 2.0 are gradually transforming port operations through better cargo visibility, faster clearance, and predictive analytics. Automation, drone-assisted inspection, and smart cargo tracking are reducing dwell times and improving competitiveness. Yet, adoption remains uneven across ports, with smaller facilities struggling to match the efficiency of private terminals such as Mundra or Krishnapatnam. As India builds its maritime grid, data-driven coordination must become a policy priority — linking ports, customs, and logistics players into a seamless digital ecosystem.
However, infrastructure spending is already stretched across competing priorities — highways, airports, and high-speed rail. Limited fiscal space will compel policymakers to prioritise among ports and projects. The next wave of investment is likely to deepen major ports such as Mundra, Jawaharlal Nehru Port, and Paradip, while developing greenfield deep-water facilities like Vadhavan and Great Nicobar. The task is to balance economic returns with strategic significance.
Reforming maritime governance
India’s port governance is undergoing its most significant overhaul in a century. The Indian Ports Bill, 2025 — replacing the colonial-era 1908 law — seeks to modernise management, strengthen coordination between the Centre and states, and update safety and environmental standards. Complementary reforms under the Merchant Shipping Act, 2025 and the Carriage of Goods by Sea Act, 2025 are designed to align India’s framework with global best practices.
The challenge, however, lies in institutional capacity. Past experience suggests that even the best-intentioned reforms can stumble amid bureaucratic overlaps and weak enforcement.
Execution on the ground depends as much on coastal states as on the Centre. States such as Gujarat and Tamil Nadu have built strong maritime ecosystems through proactive industrial policies and efficient maritime boards, while others lag due to weak institutional capacity and political friction. The new Indian Ports Bill rightly seeks to harmonise port regulation, but maritime governance remains fragmented across jurisdictions. Environmental clearances, land acquisition, and rehabilitation fall within state purview, often slowing project timelines. Achieving the goals of Maritime India Vision 2047 will require not just reform at the top but greater alignment with state-level planning and coastal zone management.
Financing the blue economy
Funding remains the biggest hurdle. Public capital alone cannot sustain ₹80 lakh crore worth of projects. The government hopes to mobilise private capital through public–private partnerships (PPPs), infrastructure funds, and vehicles like the Sagarmala Finance Corporation. A proposed Maritime Development Fund of ₹25,000 crore aims to spur investment in shipbuilding and port modernisation.
Yet, India’s track record with PPPs in the maritime sector has been uneven. Investors often cite traffic risks, tariff uncertainties, and regulatory unpredictability. Unless these structural bottlenecks are addressed, private participation will remain tepid—limiting the blue economy’s potential.
Ports are only as competitive as the ships they serve. India’s merchant fleet accounts for less than 1% of global tonnage, forcing the country to rely heavily on foreign carriers for trade transport. This dependence raises freight costs and exposes India to supply chain shocks. A vibrant shipping industry—supported by domestic shipbuilding, repair facilities, and coastal shipping incentives—is essential to leverage port modernisation. Policies such as the Shipbuilding Financial Assistance Policy (2016–2026) and incentives under the Maritime India Vision need faster execution and stronger integration with defence and commercial shipping needs. Building maritime muscle means nurturing industrial capacity, not just constructing ports.
Towards a green maritime future
Sustainability has become a defining benchmark for port development. All 12 major ports are expected to achieve carbon neutrality by 2047, with intermediate green energy goals by 2035. Ports like Kandla, Paradip, and Tuticorin have been identified as green hydrogen hubs. These align with global climate goals, but require technological readiness and supply-chain innovation.
India’s capacity in green propulsion systems, hydrogen storage, and clean bunkering is still nascent. Without targeted R&D investments and international partnerships, the transition could lag behind the ambition.
The sustainability challenge extends beyond carbon neutrality. Coastal ecosystems are under strain from dredging, land reclamation, and erosion caused by aggressive port expansion. Fishing communities—vital to the coastal economy — often bear the brunt of displacement and livelihood loss. Projects such as Vizhinjam in Kerala and Dhamra in Odisha have triggered debates about the cost of progress. A truly green maritime vision must incorporate coastal resilience, mangrove restoration, and community participation in planning. The government’s blue economy ambitions will ring hollow if ecological integrity and social consent are treated as afterthoughts.
History shows that grand visions often collapse under weak coordination. The ₹5.5 lakh crore worth of Sagarmala projects currently under implementation will test the government’s ability to deliver. Unless central ministries, state maritime boards, and private operators work in sync, India’s maritime expansion may remain a patchwork of disconnected projects rather than an integrated network.
From the ancient trade routes linking Rome and Southeast Asia to the colonial exploitation of its coasts, the seas have always shaped India’s destiny. The Maritime India Vision 2047 offers a rare chance to steer that legacy toward prosperity and self-reliance — provided the vision is matched by execution discipline.
