RB-IOS 2026: Deep-Sea Mining, Ocean Governance, and India's Blue Economy

🗞️ Why in News The Responsible Business for Inclusive Oceans Symposium (RB-IOS 2026) opened in Chennai on January 18, 2026, co-organised by the International Seabed Authority (ISA) and India’s Ministry of Earth Sciences, focusing on equitable governance of deep-sea mineral resources and the integration of developing nations into ocean economy decision-making.

The Ocean as a Resource Frontier

The Earth’s oceans cover 71% of the planet’s surface and contain resources that are increasingly critical to 21st-century technology:

• Polymetallic nodules: potato-sized rocks on the deep ocean floor, rich in manganese, nickel, copper, and cobalt — metals essential for electric vehicle batteries and electronics
• Seafloor massive sulphides (SMS): mineral deposits around hydrothermal vents containing copper, zinc, gold, and silver
• Cobalt-rich ferromanganese crusts: on the flanks of seamounts; high cobalt concentrations critical for battery cathodes
• Rare Earth Elements (REE): found in deep-sea muds in the Pacific; crucial for permanent magnets in wind turbines and electric motors

The surge in demand for these critical minerals — driven by the energy transition — has made the deep ocean economically attractive. Deep-sea mining (DSM) is the extraction of these resources from depths of 200–6,000 metres.

International Seabed Authority (ISA)

Legal Basis

The International Seabed Authority was established under Part XI and Annex VI of UNCLOS (United Nations Convention on the Law of the Sea), which was adopted in 1982 and entered into force in 1994. UNCLOS divides the ocean into zones:

The Area — the seabed, ocean floor, and subsoil beyond national jurisdiction — is designated as the “Common Heritage of Mankind” under UNCLOS Article 136. This means no state or individual can claim sovereignty over it; its resources must be exploited for the benefit of all humanity, with particular attention to the needs of developing countries.

ISA’s Role and Structure

ISA regulates all mineral-related activities in the Area through:

• Exploration contracts: allowing states and private companies to explore (but not yet exploit) mineral deposits
• Mining Code: the regulatory framework governing extraction (currently being finalised)
• Enterprise: ISA’s own commercial arm (not yet operational), intended to conduct mining on behalf of developing countries

Headquarters: Kingston, Jamaica Members: 168 member states + the European Union India’s relationship: India was one of the first countries to receive an ISA exploration licence in 1987 — one of the “Pioneer Investors”

The “Two-Year Rule” Trigger

In 2021, Nauru (a Pacific small island state) triggered the UNCLOS “two-year rule” on behalf of a sponsored company (The Metals Company, TMC) — notifying ISA that it would submit a plan of work for exploitation within two years. This obligated ISA to complete the Mining Code by July 2023, whether ready or not. The deadline was missed, and the legal status of exploitation requests remains contested — a major controversy at RB-IOS 2026.

India’s Deep-Sea Interests

Exploration Licences

India holds ISA exploration contracts through the Ministry of Earth Sciences (MoES) for:

1. Central Indian Ocean Basin (CIOB) — Polymetallic Nodules:

   • First-ever ISA exploration licence: 1987 (Pioneer Investor)
   • Area: ~150,000 km² in the CIOB
   • Resources: polymetallic nodules (manganese, nickel, cobalt, copper)
   • Indian operator: National Institute of Ocean Technology (NIOT) and India

2. Indian Ocean — Polymetallic Sulphides (Hydrothermal Vents):

   • Exploration area: Carlsberg Ridge and Rodrigues Triple Junction
   • Resources: copper, zinc, silver, gold from seafloor sulphide deposits

Deep Ocean Mission

Deep Ocean Mission (DOM) — launched 2021 by MoES — is India’s Rs 4,077 crore initiative to develop:

• Matsya 6000: a crewed deep-sea submersible capable of diving to 6,000 m (National Institute of Ocean Technology, NIOT, Chennai)
• Technologies for deep-sea mining and exploration
• Marine biodiversity documentation at depth
• Seabed mapping and resource assessment

Key Issues at RB-IOS 2026

1. Environmental Governance Gap

Deep-sea ecosystems are among the least understood on Earth. Hydrothermal vents host chemosynthesis-based food chains (not dependent on sunlight) with entirely unique species — some found nowhere else. Polymetallic nodule fields are habitats for slow-growing fauna; disturbing them generates sediment plumes that can travel hundreds of kilometres.

Key concern: ISA’s environmental regulations are being developed in parallel with exploitation pressure — the precautionary principle has not been formally adopted into the Mining Code.

2. Benefit-Sharing for Developing Countries

UNCLOS mandates that the exploitation of the Area’s resources must benefit all humanity — but especially developing countries. The Enterprise (ISA’s commercial arm) was designed to ensure this, but has never become operational. Sponsoring states (like Nauru, Tonga) are being used by multinational companies to access ISA licences without genuine benefit flowing to the island states.

India at RB-IOS 2026 advocated for:

• Operationalising the Enterprise
• Mandatory technology transfer to developing country operators
• Transparent and fair royalty and revenue-sharing structures

3. Moratorium Debate

Multiple Pacific island states, environmental NGOs (led by the Deep Sea Conservation Coalition), and some European governments have called for a moratorium on DSM until environmental baselines are established and robust regulations are in place. The International Union for Conservation of Nature (IUCN) passed a moratorium resolution in 2021.

Proponents of mining (particularly sponsoring states and mining companies) argue that land-based mining of the same critical minerals (cobalt from Congo, nickel from Indonesia) causes far greater environmental and social damage.

India’s Blue Economy Vision

The term “Blue Economy” encompasses the sustainable use of ocean resources for economic growth, improved livelihoods, and ocean ecosystem health. Key components for India:

India aims for the Blue Economy to contribute $1 trillion to GDP by 2030 — roughly 10× the current contribution.
