The set of agreements built on the 1959 Antarctic Treaty that reserves the continent south of 60 degrees South for peace and science and freezes all territorial claims.
The Antarctic Treaty System is the body of international agreements that governs Antarctica. Its foundation is the Antarctic Treaty, signed in Washington DC on 1 December 1959 by 12 countries active in the International Geophysical Year and in force from 23 June 1961. The treaty applies to the area south of 60 degrees South latitude, reserves it exclusively for peaceful purposes, guarantees freedom of scientific research and cooperation, and - crucially - freezes all territorial claims without either recognising or denying them. Around this core sit three further instruments: the Convention for the Conservation of Antarctic Seals (1972), the Convention on the Conservation of Antarctic Marine Living Resources or CCAMLR (1980), and the Protocol on Environmental Protection, known as the Madrid Protocol (1991). As of 2026 there are 58 parties, of which 29 hold consultative status with the right to take part in decisions at the annual Antarctic Treaty Consultative Meeting. India is one of them.
Type: TreatyPeaceful purposes only (Article I) - all military measures are banned, including bases, manoeuvres and weapons testing, though military personnel and equipment may be used for scientific or other peaceful support.
Freedom of scientific investigation and cooperation (Articles II and III) - plans, observations and results must be exchanged freely, and scientists exchanged between expeditions.
Territorial claims frozen (Article IV) - existing claims are neither recognised nor renounced, no new or enlarged claim may be asserted while the treaty is in force, and no activity creates a basis for a claim.
Nuclear-free (Article V) - nuclear explosions and the disposal of radioactive waste in Antarctica are prohibited, making Antarctica the world's first nuclear-weapon-free zone.
Area of application (Article VI) - everything south of 60 degrees South, ice shelves included, while leaving high-seas rights under international law untouched.
Open inspection (Article VII) - any consultative party may designate observers with complete freedom of access at any time to any station, installation, ship or aircraft.
Two classes of party - consultative parties, which conduct substantial research activity and take decisions by consensus, and non-consultative acceding parties, which may attend but not decide.
Frequency: A steady UPSC Prelims topic in environment and international relations; questions have appeared on the treaty's provisions, on CCAMLR and on India's polar stations, with salience rising after India hosted the ATCM in 2024.
The treaty grew directly out of the International Geophysical Year of 1957-58, when twelve nations ran coordinated scientific programmes in Antarctica and found that cooperation worked better than the competing territorial claims of the preceding decades. Rather than resolve those claims - an impossible task, since several overlapped - the negotiators set them aside. The system then grew outward as new pressures appeared: sealing in the 1970s, krill fishing in the 1980s, and mineral prospecting, which produced a minerals convention (CRAMRA) in 1988 that was abandoned after Australia and France refused to ratify it, and was replaced by the far stronger Madrid Protocol in 1991.

Indian Antarctic Act, 2022
Antarctica holds the overwhelming bulk of the world's ice and is central to sea-level rise, ocean circulation and the palaeoclimate record locked in its ice cores - which is why access to it is a scientific interest, not merely a diplomatic one. The treaty is also the rare case of a whole continent demilitarised and de-nationalised by agreement, achieved at the height of the Cold War with both the United States and the Soviet Union among the original signatories. For India, consultative status buys a say in how the continent is governed and a seat at decisions about krill fishing, tourism regulation and any future move on minerals - an interest that grows as the 2048 review date for the mining ban approaches.
Antarctic Treaty signed 1 December 1959 at Washington DC by 12 nations; in force 23 June 1961.
Applies south of 60 degrees South; peaceful use only; territorial claims frozen under Article IV; nuclear explosions and radioactive waste banned.
58 parties in 2026; 29 consultative parties decide by consensus at the annual ATCM.
The ATS comprises the Treaty plus CCAS (1972), CCAMLR (1980, HQ Hobart) and the Madrid Protocol (1991, in force 1998).
The Madrid Protocol makes Antarctica a natural reserve devoted to peace and science and bans mineral activity; reviewable from 2048.
Secretariat at Buenos Aires since 2004; scientific advice from SCAR.
India acceded in August 1983 and became consultative in September 1983; stations Dakshin Gangotri (1983), Maitri (1989), Bharati (2012); Maitri-II due January 2029.
The Indian Antarctic Act, 2022 domesticates the treaty with a permit system and a governance committee; NCPOR in Goa runs the programme.
As of 2026 there are 58 parties. Of these, 29 hold consultative status, meaning they conduct substantial scientific research in Antarctica and take part in decisions at Consultative Meetings.
No. Article IV freezes the position - existing claims are neither recognised nor given up, no new or enlarged claim may be made while the treaty is in force, and no activity in Antarctica creates a basis for a claim.
India operates Maitri, commissioned in 1989 at Schirmacher Oasis, and Bharati, operational since 2012 in the Larsemann Hills. Its first station, Dakshin Gangotri (1983), was later decommissioned after being buried in ice. A new station, Maitri-II, is expected to be operational by January 2029.
No. The Madrid Protocol of 1991 prohibits any activity relating to mineral resources except scientific research. The prohibition can be reviewed from 2048, fifty years after the Protocol entered into force.
Consultative parties conduct substantial research activity in Antarctica and take part in decision-making by consensus at the ATCM. Non-consultative acceding parties are bound by the treaty and may attend meetings, but do not take part in decisions.
