Peros Banhos is an atoll in the Indian Ocean located within the Chagos Archipelago and administered as part of the British Indian Ocean Territory. The atoll has been the focus of territorial claims by Mauritius and has featured in litigation at the International Court of Justice and proceedings at the Permanent Court of Arbitration. Historically inhabited by Chagossians, the atoll became depopulated following actions taken by the United Kingdom and United States during the Cold War era associated with the establishment of military facilities on Diego Garcia.

Geography

Peros Banhos is one of the central atolls of the Chagos Archipelago in the Indian Ocean and lies north of Diego Garcia, south of Seychelles, and east of Madagascar. The atoll comprises numerous islets including Île Fouquet, Île Lampart, Île Mapou, and Île du Coin and encloses a shallow lagoon with channels used historically for small craft associated with coconut plantations linked to plantation economy structures such as those operated under British Empire colonial administration. The reef system supports coral structures comparable to those studied near Aldabra Atoll and Maldives formations, and its geomorphology has been mapped by hydrographic surveys from institutions like the Royal Navy and the United States Geological Survey.

History

Peros Banhos was frequented by seafarers from the Arab world, Portuguese Empire, and later visited by ships of the Dutch East India Company and the British East India Company during the era of Indian Ocean trade. In the 18th and 19th centuries, the atoll was incorporated into colonial frameworks under the French colonial empire and later the British Empire, with plantation labor sourced via indenture patterns tied to Mauritius and the wider Indian Ocean slave trade legacy. In the 20th century, the islands were inhabited by Chagossians until depopulation occurred in the 1960s and 1970s when the United Kingdom entered agreements with the United States related to strategic facilities on Diego Garcia, precipitating legal disputes taken to the European Court of Human Rights, the International Court of Justice, and arbitration under the United Nations Convention on the Law of the Sea frameworks. Sovereignty claims by Mauritius culminated in advisory opinions and resolutions at the United Nations General Assembly, and diplomatic discussions have involved states including the United Kingdom, United States, and regional actors such as the African Union.

Flora and Fauna

The atoll’s terrestrial vegetation historically featured coconut plantations and native species, with flora comparable to that catalogued at Aldabra and within Seychelles biodiversity surveys, and botanists from institutions like the Royal Botanic Gardens, Kew have documented species present. Avifauna includes seabird colonies with affinities to species recorded on Christmas Island (Indian Ocean), Cocos (Keeling) Islands, and Ile aux Aigrettes, and islets serve as nesting habitat for sooty tern, masked booby, and other pelagic birds studied by ornithologists from the British Ornithologists' Union and BirdLife International. Marine biodiversity features coral communities and reef fish assemblages subject to comparative studies by researchers at Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, and regional marine science programs under the Indian Ocean Commission.

Economy and Infrastructure

Prior to depopulation, the atoll’s economy centered on coconut production, copra processing, and small-scale reef fishing linked to trade routes connecting Mauritius, Réunion, and Seychelles. Infrastructure historically included plantation housing, jetty works, and coconut processing facilities influenced by colonial-era investments from firms associated with British commercial interests and shipping links to ports such as Port Louis. Since depopulation, permanent civilian infrastructure has been minimal, with periodic visits and logistical operations carried out by vessels and organizations including the British Indian Ocean Territory administration and scientific teams from universities such as University of Oxford and University of Cambridge.

Conservation and Environmental Issues

Peros Banhos has been central to regional conservation initiatives led by organizations such as Chagos Conservation Trust, BirdLife International, and intergovernmental programs under the United Nations Environment Programme and Indian Ocean Commission. Environmental concerns include coral bleaching linked to climate change, plastic pollution documented in studies by National Oceanic and Atmospheric Administration and Greenpeace, and invasive species impacts similar to those addressed in eradication projects on Aldabra and Ile aux Aigrettes. Proposals for marine protected areas and no-take zones have involved input from the International Union for Conservation of Nature and have been subject to policy debate among the United Kingdom, Mauritius, and international bodies such as the United Nations General Assembly.

Administration and Demographics

Administratively, the atoll falls under the British Indian Ocean Territory claimed in parallel by Mauritius; governance questions have been the subject of rulings at the International Court of Justice and resolutions in the United Nations General Assembly. Demographically the atoll is uninhabited following the displacement of Chagossians whose resettlement claims have been litigated in the European Court of Human Rights, domestic courts of the United Kingdom, and tribunals under the Mauritius–United Kingdom diplomacy. The status of the atoll continues to feature in bilateral discussions involving the Foreign and Commonwealth Office and diplomatic engagements with actors such as the African Union and regional organizations including the Commonwealth of Nations.
