The only inhabitants are British and United States military personnel, and associated contractors, who collectively number around 3,000 (2018 figures).[3] The forced removal of Chagossians from the Chagos Archipelago occurred between 1968 and 1973. The Chagossians, then numbering about 2,000 people, were expelled by the British government to Mauritius and Seychelles, even from the outlying islands far away from the military base on Diego Garcia. Today, the Chagossians are still trying to return, but the British government has repeatedly denied them the right of return despite calls from numerous human rights organisations to let them.[10][11] The islands are off-limits to Chagossians, tourists, and the media.
Maldivianmariners knew of the Chagos Islands, which were known as Fōlhavahi in the northern Maldives, and Hollhavai in the southern Maldives. Hollhavai also referred to other islands scattered throughout the Indian Ocean, such as the Seychelles. According to Southern Maldivian oral tradition, traders and fishermen were occasionally lost at sea and got stranded on one of the islands of the Chagos. Eventually they were rescued and brought back home. The coconut crabs of the islands may have inspired Maldivian folklore about giant hermit crabs. These islands were judged to be too far away from the seat of the Maldivian crown to be settled permanently by them. Thus, for many centuries the Chagos were ignored by their northern neighbours.[13]
Early settlement
The islands of Chagos Archipelago were charted by Vasco da Gama in the early 16th century, and then claimed in the 18th century by France as a possession of Mauritius. They were first settled in the 18th century by African slaves and Indian contractors brought by Franco-Mauritians to found coconut plantations.[14] At some point Diego Garcia hosted a leper colony for patients from Mauritius, who were treated with turtle oil.[15] In 1810, Mauritius was captured by the United Kingdom, and France subsequently ceded the territory in the Treaty of Paris in 1814.
The United Kingdom abolished slavery in 1833, although those on what would become the BIOT continued work as indentured labour. In 1883 the plantations were bought by the Société Huilière de Diego et Peros. As of 1900 there were 426 families on the islands, 60 percent descended from the original African-Malagasy slaves, and 40% descended from South Asians brought over as indentured labour. Chagossian creole developed as a common language.[16] The lives of the population remained effectively controlled by the company, a system which persisted until the 1960s.[17]: 62
An airstrip was built on Diego Garcia during the Second World War along with other military facilities. Military forces left once the war ended. In 1962 the plantations were bought by Chagos-Agalega Company, based in the Seychelles. At this time they covered 3,000 hectares (7,400 acres).[16]
Formation
The descendants of those brought to the islands to farm coconuts had developed into the Chagossian people.[16] There are no official population figures, but an estimate from 1968 found 866 inhabitants: 336 in Diego Garcia, 162 in the Salomon islands, and 168 in Peros Banhos. The vital statistics were likely similar to other Indian Ocean islands. The birth rate on the Chagos archipelago was probably around 48 in every 1000. The birth rate for the former Seychellois islands was nominally lower, likely due to inhabitants more easily able to travel to the Seychelles for medical needs. Mortality before the age of 1 was around 98 per 1,000 live births. The overall death rate probably averaged under 12 per 1,000 people. Housing was simple, mostly using local wood and coconut leaves, with some imported concrete and corrugated iron. Most water was captured from rain, although there were groundwater wells. The islands at this time produced not only copra from the plantations, but fish, and fruit in the case of the Chagos archipelago. Alcohol was produced for local consumption, from coconut, sugar cane, and other materials. It is likely there was some malnutrition.[15]
Beginning in February 1964, the UK and US began secret talks about a military base in Diego Garcia. The US wanted a territory with no local population, and the islands were lightly inhabited compared to other potential locations.[16] The initial option of Aldabra was dropped due to international interest in its ecosystem.[17]: 65 In 1965, the United Kingdom split the Chagos Archipelago from Mauritius and the islands of Aldabra, Farquhar and Desroches (Des Roches) from the Seychelles to form the British Indian Ocean Territory (BIOT). The purpose was to allow the construction of military facilities for the mutual benefit of the United Kingdom and the United States of America. The islands were formally established as an overseas territory of the United Kingdom on 8 November 1965.[18] While it initially sought for the base to be given on a lease, Mauritius was eventually paid £3 million to compensate for the territory's separation, under pressure due to then-ongoing independence negotiations.[16][17]: 67 (An additional £650,000 was given in 1972, for relocation costs.)[17]: 62
A few weeks after the decision to detach the Chagos Archipelago from Mauritius, the United Nations General Assembly passed Resolution 2066 on 16 December 1965, which stated that this detachment of part of the colonial territory of Mauritius was against customary international law as recorded earlier in the Declaration on the Granting of Independence to Colonial Countries and Peoples of 14 December 1960. This stated that "Any attempt aimed at the partial or total disruption of the national unity and the territorial integrity of a country is incompatible with the purposes and principles of the Charter of the United Nations".[19][20]
Mauritius became an independent Commonwealth realm in March 1968, and subsequently became a republic, also within the Commonwealth, in March 1992.[21]
In April 1967, the British government purchased the privately owned copra plantations for £600,000[16] and closed them. Over the next five years, the British authorities removed the entire population of about 2,000 people, known as Chagossians (or Ilois), from Diego Garcia and two other Chagos atolls, Peros Banhos and Salomon Islands, to Mauritius[22] and the Seychelles. The expulsion was carried out by preventing Chogossians who had left from returning from 1967, assisted by the Moulinie and Company (Seychelles), Limited company which the UK had set up to run the plantations. In 1968, when more workers were needed, non-Chagossian temporary workers were allowed in from the Seychelles. The remaining population was removed from Diego Garcia in January 1971, to meet a July 1971 deadline requested by the US. The populations of Peros Banhos and the Salomon Islands were removed starting from June 1972. The population as of 1965 was around 1,360 Chagossians, plus temporary workers from the Seychelles. Another few hundred Chagossians already lived outside of the islands. The UK informed the United Nations that BIOT had no indigenous population, meaning the UK would not have to send reports on the territory to the UN.[16]
In 1971, the United Kingdom and the United States signed a treaty, leasing the island of Diego Garcia to the US military for the purposes of building a large air and naval base on the island. The deal was important to the British government, as the United States granted it a substantial discount on the purchase of Polaris nuclear missiles in return for the use of the islands as a base.[23] The island was strategically located near oil shipping routes, and Iran.[17]: 66 It would counter any Soviet threat in the region.[24]
As of 1971, the population of Aldabra, Farquhar, and Desroches was 246. This dropped to 155 in 1975, likely reflecting uncertainty about these islands' future status.[15] On 23 June 1976, these islands were returned to the Seychelles, which became independent as a republic on 29 June 1976; the islands now form part of the Outer Islands district of the Seychelles. Subsequently, the territory has consisted only of the six main island groups comprising the Chagos Archipelago.
Work on the military base commenced in 1971, with a large airbase with several long range runways constructed, as well as a harbour suitable for large naval vessels. Although classed as a joint UK/US base, in practice it is primarily staffed by the US military, although the UK maintains a garrison at all times, and Royal Air Force (RAF) long-range patrol aircraft are deployed there.
During the 1980s,[year needed] Mauritius asserted a claim to sovereignty for the territory, citing the 1965 separation as illegal under international law, despite their apparent agreement at the time. The UK did not agree with the legal argument, but agreed to cede the territory to Mauritius when it was no longer required for defence purposes.[25] According to the CIA World Factbook, the Seychelles also had a sovereignty claim on the islands.[26] In 1982, the UK and US agreed waste would be shipped away from the territory.[27]: 49 On 27 December 1984, Mauritius established an exclusive economic zone (EEZ) which included the waters around the BIOT, an action protested by the UK.[27]: 53–54
In 1990, the first BIOT flag was unfurled. This flag, which also contains the Union Jack, has depictions of the Indian Ocean, where the islands are located, in the form of white and blue wavy lines and also a palm tree rising above the British crown.[28] During the Gulf War, 20 nuclear-armed Boeing B-52 Stratofortress bombers were stationed at the base as a nuclear deterrent.[27]: 42 The base was also strategically positioned to support the 2001 War in Afganistan and the 2003 Iraq War.[17]: 66
On 1 October 1991, the UK created the "BIOT Fisheries Conservation and Management Zone (FCMZ)" covering the territorial seas of the BIOT.[27]: 55–56 On 4 December 1995, the UK signed the United Nations Fish Stocks Agreement on behalf of the BIOT, which was protested by Mauritius when it signed in 1997.[27]: 55 Both Mauritius and the United Kingdom agreed to the inclusion of the BIOT within the area covered by the Indian Ocean Tuna Commission, which was formed in 1996.[27]: 54 In 1996 the Mauritius Marine Conservation Society unsuccessfully sought to have the archipelago declared a World Heritage Site.[27]: 52 Mauritius explicitly extended its ratification of the Nairobi Convention to the Chagos archipelago in 2000, although this had limited practical impact.[27]: 53
The islanders, who now mainly reside in Mauritius and Seychelles, have continually asserted their right to return to Diego Garcia, winning important legal victories in the High Court of England and Wales in 2000, 2006, and 2007. In the High Court and Court of Appeal in 2003 and 2004, the islanders' application for further compensation on top of the £14.5 million value package of compensation they had already received was dismissed by the court.[29] Following the 2000 ruling the British government announced that Chagossians would be permitted to return to the archipelago, aside from Diego Garcia. This position was reversed in 2004, before any had moved. The United Kingdom offered citizenship to some Chagossians starting in 2002.[16]
On 17 September 2003, the UK created the "BIOT Environmental Protection and Conservation Zone (EPCZ)" covering the BIOT's EEZ. This was opposed by Mauritius, which on 5 August 2005 reasserted their declared EEZ surrounding the territory.[27]: 55–56
On 11 May 2006, the High Court ruled that a 2004 Order in Council preventing the Chagossians' resettlement of the islands was unlawful, and consequently that the Chagossians were entitled to return to the outer islands of the Chagos Archipelago.[30] On 23 May 2007, this was confirmed by the Court of Appeal.[31] In a visit sponsored by the British government, the islanders visited Diego Garcia and other islands on 3 April 2006 for humanitarian purposes, including the tending of the graves of their ancestors.[32] On 22 October 2008, the British government won an appeal to the House of Lords regarding the royal prerogative used to continue excluding the Chagossians from their homeland.[33][34]
In March 2007 Mauritian president Anerood Jugnauth declared a willingness to take the dispute to the ICJ, and for Mauritius to leave the Commonwealth. In November 2007 a line of communication was established between the Foreign & Commonwealth Office and the Mauritian High Commission for BIOT-related matters.[25]
The British government established the BIOT Marine Protected Area in April 2010, to mixed reactions from Chagossians. While the British Foreign and Commonwealth Office claimed that it was an environmental move as well as a necessary move to improve the coral populations off east Africa, and therefore sub-Saharan marine supplies, some Chagossians claimed that the reserve would prevent any resettlement due to the inability to fish in protected areas. The Chagossian UK-based Diego Garcian Society stated that it welcomed the marine reserve, noting that it was in the interest of Chagossians to have the area protected while they were exiled and that it could be renegotiated upon resettlement. The Foreign Office claimed the reserve was made "without prejudice to the outcome of proceedings before the European Court of Human Rights".[35] (That court's 2012 decision was not in favour of the Islanders anyway.)[36] The protected area covered the territory's EEZ, but not its territorial waters.[27]: 58
International opinion and rulings
In 2009 Mauritius began negotiating with the Maldives to jointly settle the borders of EEZs in the area. These were unsuccessful, and in 2010 the Maldives submitted a claim that overlapped with both British and Mauritian claims. The Maldives contended that as much of the northern Chagos archipelago was uninhabited, they should not be included in the determination of EEZ baselines.[27]: 57 Arbitration between the UK and Mauritius relating to the creation of the marine protected area began in 2010.[27]: 36 This arbitration was cited by Mauritius to halt an attempt by a coalition of NGOs to have the archipelago declared a World Heritage site in 2012.[27]: 52 In 2015 an UNCLOS tribunal ruled that the creation of a marine protected area violated British obligations.[16] The idea to create a formal protected area was dropped.[17]: 68
The US-UK arrangement which established the territory for defence purposes initially was in place from 1966 to 2016, and has subsequently been renewed to continue until 2036. The announcement was accompanied by a pledge of £40 million in compensation to former residents.[37] The base was seen as important for managing growing Chinese influence in the region.[17]: 67
The formerly obscure sovereignty dispute gained more international recognition as Mauritius obtained the support of other African countries. Brexit deprived the United Kingdom of support from European allies.[38] In May 2017, Mauritius challenged the presence of the UK at a meeting of the Indian Ocean Tuna Commission.[27]: 55 On 22 June 2017 the United Nations General Assembly (UNGA) voted to refer the issue to the International Court of Justice (ICJ) by 94 to 15. There were 65 abstentions, including British allies such as Canada, France, and Germany.[39][40] In February 2019, the ICJ issued an advisory opinion by 13 votes to 1.[40] In its advisory opinion, the Court concluded that "the process of decolonisation of Mauritius was not lawfully completed when that country acceded to independence", and that "the United Kingdom is under an obligation to bring to an end its administration of the Chagos Archipelago as rapidly as possible".[41][42] On 22 May 2019, the UNGA adopted a resolution citing the ICJ advisory opinion, affirming that "the Chagos Archipelago forms an integral part of the territory of Mauritius".[43] The motion was approved by a majority vote with 116 member states voting for and 6 against.[43] Votes against included the neighbouring Maldives, possibly concerned about the loss of maritime security benefits that emerge from the military base. The Seychelles benefits similarly, but voted for the resolution in solidarity with the African Union.[44]
On 28 January 2021, the United Nation's International Tribunal for the Law of the Sea ruled, in a dispute between Mauritius and Maldives on their maritime boundary, that the United Kingdom has no sovereignty over the Chagos Archipelago, and that Mauritius is sovereign there. The United Kingdom disputes and does not recognise the tribunal's decision.[45][46] As with the ICJ decision, this decision had no legal compulsion, although both contributed to international pressure on the UK.[17]: 61 The Universal Postal Union (UPU), which has jurisdiction over international mail among treaty signatory states, voted in 2021 to ban the use of BIOT postage stamps on mail from BIOT, instead requiring Mauritian stamps to be used.[47]
In February 2022, exiled islanders made their first unsupervised visit to an island in the Chagos Archipelago.[48] The Permanent Representative of Mauritius to the United Nations, Jagdish Koonjul, raised the Mauritian flag on Peros Banhos.[49][50] The main purpose of the 15-day Mauritian expedition is to survey the unclaimed Blenheim Reef, to discover for a forthcoming International Tribunal for the Law of the Sea hearing if it is exposed at high tide so is claimable.[51][52] The chartered Bleu De Nîmes was shadowed by a British fisheries protection vessel.[53]
In October 2021 Sri Lankan Tamil asylum seekers landed on Diego Garcia, and submitted asylum claims. The Convention Relating to the Status of Refugees does not apply to the BIOT. Around 173 arrived in 2021 and 2022. Some were moved to Rwanda, with around 60 left as of January 2024.[16][54] In 2022, a dispute arising from American defence contractor KBR allegedly prohibiting holidays during a period of low flight demand during the COVID-19 pandemic led to 800 Overseas Filipino Workers being unable to leave Diego Garcia.[55]
Post-ICJ negotiations
Comparisons between the BIOT and occupied areas of Ukraine hindered British diplomatic efforts to obtain Ukrainian support following the Russian invasion of Ukraine. Further pressure grew regarding Africa's "last colony", and in September 2022 British prime minister Liz Truss met with Mauritian prime minister Pravind Jugnauth[56][17]: 60–61 On 3 November 2022, the British Foreign Secretary James Cleverly announced that the UK and Mauritius had decided to begin negotiations on sovereignty over the British Indian Ocean Territory, taking into account international legal proceedings. Both states had agreed to ensure the continued operation of the joint UK/US military base on Diego Garcia.[57][58] The Carnegie Endowment for International Peace has argued this change of approach is partly due to strategic shifts in US and UK foreign policies on Asia in response to China's growing power and influence, as disputes with former colonies encourage their deepening relationship with China.[59]
On 3 November 2022, Patrick Wintour of the Guardian reported that the UK and Mauritius had begun negotiations on sovereignty over the British Indian Ocean Territory, taking into account the international legal proceedings.[57] In December 2023, Tony Diver of the Daily Telegraph reported that the British government was planning to discontinue the talks.[60] These negotiations ceased in late 2023 after the UK Defence Secretary blocked the agreement that had been negotiated by the Foreign Office.[60]
On 3 October 2024, British prime minister Keir Starmer and Mauritian prime minister Pravind Jugnauth jointly announced that an agreement had been reached under which the UK would cede sovereignty over the territory. Under the deal, Diego Garcia will be excluded from any resettlement, and the UK will continue to administer the island for at least 99 years.[38][12] Chagos Islanders would be allowed to return to the other islands and a fund will be established to support resettlement.[61]
No debate on the deal had taken place in the Parliament of the United Kingdom due to it being in recess, and the deal attracted criticism from opposition politicians such as James Cleverly,[62] who, as foreign secretary, had initiated the negotiations that took place from November 2022 until December 2023.[60] The announcement was also criticised by the Speaker of the House of Commons, Sir Lindsay Hoyle, who criticised the government for ignoring the constitutional convention that important matters should be announced in the House of Commons first.[63] Some Chagossians have also criticised the deal for not having included the Chagossian community in the decision-making process.[64]
Government
King Charles III is the head of state of the British Indian Ocean Territory.
The head of government is the Commissioner, most recently Paul Candler until August 2024; the Deputy Commissioner is Nishi Dholakia, and the Administrator is Emily Ager, and all senior officials reside in the United Kingdom.[65] The Commissioner's Representative in the territory is the officer commanding the detachment of British forces.[66]
The laws of the territory are based on the constitution, currently set out in the British Indian Ocean Territory (Constitution) Order 2004, which gives the Commissioner power to make laws for the peace, order and good government of the territory.[67][66][68] If the Commissioner has not made a law on a particular topic then, in most circumstances, the laws that apply in the territory are the same as those that apply in England and Wales under the terms of the Courts Ordinance 1983.[69] There is no legislature (and no elections) as there are no permanent inhabitants, although a small legal system has been established for the jurisdiction. As almost all residents of the BIOT are members of the United States military, in practice, crimes are more commonly charged under United States military law.
Applicable treaties between the United Kingdom and the United States govern the use of the military base. The first exchange of notes, signed on 30 December 1966, constituted an agreement concerning the availability for defence purposes of the British Indian Ocean Territory.[70] This was followed by agreements on the construction of a communications facility (1972), naval support facility (1976), construction contracts[permanent dead link] (1987), and a monitoring facility (1999). The United States is reportedly required to ask permission[citation needed] of the United Kingdom to use the base for offensive military action.
As the BIOT forms a separate legal jurisdiction to the United Kingdom under British law, many international conventions signed by the United Kingdom were not extended to the BIOT.[27]: 39, 46 These include humanitarian treaties, including the 1951 Refugee Convention and the International Covenant on Civil and Political Rights, which makes the legal situation difficult.[71][72] While the UK has joint jurisdiction over the military base, the British government contends that US warships around the base are responsible solely to the US, and thus do not need to meet British treaty obligations.[27]: 43
Naval Party 1002 and MV Grampian Frontier
Naval Party 1002 (NP 1002) is directly present in the territory, and is composed of both Royal Navy and Royal Marine personnel. NP 1002 is responsible for civil administration and enforcement. Its members are tasked with policing and carrying out customs duties. Royal Marines in the territory also reportedly form a security detachment.[73]
Prior to 2017, the BIOT patrol vessel, MV Pacific Marlin, was based in Diego Garcia. It was operated by the Swire Pacific Offshore Group. The Pacific Marlin patrolled the marine reserve all year, and since the marine reserve was designated in April 2010, the number of apprehensions of illegal vessels within the area has increased. The ship was built in 1978 as an ocean-going tug. It is 57.7 metres (189 feet 4 inches) long, with a draught of 3.8 metres (12 feet 6 inches), and gross tonnage of 1,200 tons. It has a maximum speed of 12.5 knots (23.2 kilometres per hour; 14.4 miles per hour) with an economic speed of 11 knots (20 kilometres per hour; 13 miles per hour), permitting a range of about 18,000 nautical miles (33,000 kilometres; 21,000 miles) and fuel endurance of 68 days. It was the oldest vessel in the Swire fleet.[74]Pacific Marlin reportedly spent about 54% of her taskings on fishery patrol duties, and a further 19% on military patrol duties.[75]
In 2016, a new contract was signed with Scottish-based North Star Shipping for the use of the vessel MV Grampian Frontier[75] (also known as the Grampian Endurance).[76] She is a 70 metres (230 feet) vessel carrying up to 24 personnel, and fulfils both the patrol and research role.[75] The vessel reportedly operates in conjunction with personnel from NP 1002 on both fisheries and military enforcement tasks / exercises, and also carries scientists / researchers involved in a range of research work, particularly conservation.[77] In 2022, Grampian Frontier tracked a Mauritian-charted vessel temporarily bringing Chagossian exiles to Blenheim Reef in the archipelago.[78]
The Royal Navy also maintains two offshore patrol vessels in the Indo-Pacific region, HMS Tamar and HMS Spey. Either may be periodically employed for sovereignty protection and other duties in BIOT waters.[79][80] HMS Tamar paid a rare visit to the islands in February/March 2023 conducting fisheries protection and other missions.[81]
The British Indian Ocean Territory prior to the Seychelles's independence in 1976. The land at bottom left is the northern tip of Madagascar. (Desroches is not labelled, but is a part of the Amirante Islands.)Map of the British Indian Ocean Territory since 1976.
The territory is an archipelago of 58 islands covering 56 square kilometres (22 sq mi). The largest island is Diego Garcia, which at 32.5 square kilometres (12.5 sq mi) accounts for about half of the territory's total land area. The rest of the island's are much smaller, with the second largest being just over 3.1 square kilometres (1.2 sq mi).[17]: 65 The terrain is flat and low,[citation needed] with an average elevation of 1.33 metres (4.4 ft) above sea level.[27]: 50 In 2010, 545,000 square kilometres (210,000 square miles) of ocean around the islands was declared a marine reserve.[35]
These islands and associated coral reefs lie between 4°44 and 7°41 south and 70°47 and 72°47 east.[15]
As indicated above, the territory also included Aldabra, Farquhar and Desroches between 1965 and 1976; the latter group of islands is located north of Madagascar and were annexed from and returned to the Seychelles.
Climate
The climate is tropical marine; hot, humid, and moderated by trade winds.[82] These winds originate from the southeast from May to November, reversing for the rest of the year. The average temperature is 27 °C (81 °F), and does not vary greatly throughout the year. While rain is common,[15] the territory lies outside of cyclone paths that cross the Indian Ocean further south.[17]: 68 The Diego Garcia military base is the United States military's overseas base most at risk from climate change.[27]: 50
Transport
In terms of transportation on Diego Garcia, the island has short stretches of paved road between the port and airfield, and on its streets; transport is mostly by bicycle and on foot. The island had many wagonways, which were donkey-hauled narrow gauge railways for the transport of coconut wagons. These are no longer in use and have deteriorated.[83]
The airport passenger terminal in Diego Garcia, complete with red British telephone box.
Diego Garcia's military base is home to the territory's only airport. At 3,000 metres (9,800 feet) long, the runway is capable of supporting heavy US Air Force bombers such as the B-52, and would have been able to support the Space Shuttle in the event of a mission abort.[84] It also has a major naval seaport,[85] and there is also a marina bus service along the main road of the island.[86]
Yacht crews seeking safe passage across the Indian Ocean may apply for a mooring permit for the uninhabited Outer Islands (beyond Diego Garcia),[87] but must not approach within 3 nautical miles (5.6 kilometres; 3.5 miles), land on, or anchor at islands designated as Strict Nature Reserves, or the nature reserve within the Peros Banhos atoll. Unauthorised vessels or persons are not permitted access to Diego Garcia, and no unauthorised vessel is permitted to approach within three nautical miles of the island.[88]
On 1 April 2010, the Chagos Marine Protected Area (MPA) was declared to cover the waters around the Chagos Archipelago. Mauritius objected, stating this was contrary to its legal rights, and on 18 March 2015, the Permanent Court of Arbitration ruled that the MPA was illegal under the United Nations Convention on the Law of the Sea, as Mauritius had legally binding rights to fish in the waters surrounding the archipelago, to an eventual return of the archipelago, and to the preservation of any minerals or oil discovered in or near the archipelago prior to its return.[89][90]
The MPA's declaration doubled the total area of environmental no-take zones worldwide. The benefits of protecting this area are described as follows:
Providing an environmental benchmark for other areas (unlike the rest of the world, the BIOT has been relatively untouched by man's actions);
Providing a natural laboratory to help understand climate change;
Acting as a reserve for species in danger in other areas; and
Providing an export supply of surplus juveniles, larvae, seeds, and spores to help with output in neighbouring areas.[91]
The area had already been declared an Environmental (Preservation and Protection) Zone, but since the establishment of the MPA, fishing has no longer been permitted in the area.
The BIOT Administration has facilitated several visits to the territory by the eldest Chagossians, and environmental training for UK-based Chagossians that allows some to become involved in scientific work (alongside visiting scientists).[92]
The islands are surrounded by very productive fisheries.[17]: 64 As the BIOT EEZ is patrolled by only one dedicated vessel, the Grampian Frontier, it is difficult to monitor illegal fishing. A rise in illegal fishing in the early 2020s led to a decrease in sharks, and the Royal Navy ship HMS Tamar was sent to assist with monitoring efforts.[76]
Demographics
The British Indian Ocean Territory (Constitution) Order 2004 states that "no person has the right of abode" in the territory as it "was constituted and is set aside to be available for the defence purposes of the Government of the United Kingdom and the Government of the United States of America", and accordingly, "no person is entitled to enter or be present in the Territory except as authorised" by its laws.
As there is no permanent population, or census, information on the demographics of the territory is limited; the size of the population is related to its offensive requirements. Diego Garcia, with a land area of 27 square kilometres (10 square miles), is the only inhabited island in the territory, and therefore has an estimated average population density of around 110 persons per km2.
Diego Garcia's population is normally limited to official visitors and military-essential personnel only, and family members are not authorised to travel to Diego Garcia (the island therefore has no schools). Personnel may not travel to the island for leave, but they may transit through Diego Garcia to connect with follow-on flights.[93] The population in 1995 was estimated to be approximately 3,300; i.e. 1,700 UK and US military personnel and 1,500 civilian contractors. The total population was reportedly 4,000 persons in 2006, of whom 2,200 were US military personnel or contractors, 1,400 were Overseas Filipino Worker contract staff, 300 were Mauritian contract staff, and 100 were members of the British Armed Forces.[citation needed] The population had decreased to around 3,000 persons in 2018.[3]United Nations population statistics indicate that island's population is comparable to that of the Falkland Islands. The remainder of the archipelago is ordinarily uninhabited.
Marooned asylum seekers
In October 2021, 89 Sri Lankan Tamils, including 20 children, who were traveling from India to Canada in a vessel which ran into distress, were intercepted and escorted to Diego Garcia by the British military. After more than seven months without a resolution to their situation on the island, 42 of them started a hunger strike. London solicitors for 81 of them say they have been given no information about how they may claim international protection, or how long they will be kept on Diego Garcia.[94]
On 10 April 2022, a further 30 asylum seekers rescued from a second vessel joined the 89 Sri Lankans, who are being kept in a tented fenced-in camp.[95][96] On 25 October 2022, the British government stated it "remains committed to supporting their departure" and they "will not be permitted to make a claim for asylum in the UK".[97]
Further small boats with Tamil refugees that ran into difficulties were escorted to Diego Garcia, where repairs were made, and they were permitted to leave. One boat carrying 46 people went on to the French territory of Réunion.[98][72]
The BIOT commissioner ruled that the group that had arrived in October 2021 could be lawfully returned to Sri Lanka. Ten group members challenged this decision in the BIOT Supreme Court, on the basis that the decision-making process was flawed, and were granted a judicial review that was due to be heard in September 2023. Shortly before the judicial review hearing, lawyers representing the commissioner withdrew all the decisions, and the commissioner agreed to reassess each protection claim using reviewers not previously involved in the cases. The solicitor for eight of the group said: "Our clients are relieved that the BIOT commissioner has finally agreed to withdraw the unlawful decisions to forcibly return them to Sri Lanka where they face risk of torture and persecution."[99][100]
The asylum seekers live in tents in a fenced camp of approximately 100 m × 140 m (14,000 m2 or 1.4 ha), which they cannot leave without a security escort. "Most of the children have never left the camp other than infrequent visits to the beach under security escort" a report by a UN agency says. There have been reports of sexual assault (by other asylum seekers), self-harm and suicide attempts. As of February 2024, there are 61 people in the camp.[101][102]
Economy
Street in Diego Garcia. Traffic drives on the right, unlike other British territories, except for Gibraltar
All economic activity is concentrated on Diego Garcia, where joint UK/US defence facilities are located. Construction projects and the operation of various services needed to support the military installations are carried out by military, and contract employees from Britain, Mauritius, the Philippines, and the United States. There are no industrial or agricultural activities on the islands. Until the creation of the marine sanctuary, the licensing of commercial fishing provided an annual income of about US$1 million for the territory.[103]
Services
The Navy Morale, Welfare and Recreation (MWR) section provides several facilities on Diego Garcia, including a library, outdoor cinema, shops, and sports centres, with prices in US dollars. The BIOT Post Office provides outbound postal services, and postage stamps have been issued for the territory since 17 January 1968. As the territory was originally part of Mauritius and the Seychelles, these stamps were denominated in rupees until 1992, after which were issued in denominations of pound sterling, the territory's official currency. Basic medical services are provided, with the option of medical evacuation where required, and the territory has no schools.[104]
Telecommunications
Cable & Wireless started operating telecommunications services in 1982, under licence from the British government. In April 2013, the company was acquired by the Batelco Group, and Cable & Wireless (Diego Garcia) Ltd subsequently changed its name to Sure (Diego Garcia) Ltd; Sure International is the corporate division of the business.
Due to its geographic location in proximity to the Equator, with unobstructed views to the horizon, Diego Garcia has access to a relatively large number of geosynchronous satellites over the Indian and eastern Atlantic Oceans, and the island is home to Diego Garcia Station (DGS), a remote tracking station making up part of the United States Space Force's Satellite Control Network (SCN); the station has two sides to provide enhanced tracking capabilities for AFSCN users.[105]
In spring 2022, Diego Garcia was connected to a fiber-optic submarine communications cable, as a spur to the new commercial Oman Australia Cable connecting Perth to Muscat, which ran near the island. The cable also has a spur to Australia's Cocos Islands which has an airfield due to support maritime patrol aircraft. The cable cost $300 million, with the U.S. DOD contributing about a third of the cost.[106]
Broadcasting
The territory has three FM radio broadcast stations; provided by the American Forces Network (AFN) and British Forces Broadcasting Service (BFBS). Amateur radio operations occur from Diego Garcia, using the British callsign prefix VQ9. An amateur club station, VQ9X, was sponsored by the US Navy for use by operators both licensed in their home country and possessing a VQ9 callsign issued by the local British Indian Ocean Territory representative.[107] The navy closed the station in early 2013, and any future licensed amateurs wishing to operate from the island would therefore have had to provide their own antenna and radio equipment.[108]
.io domain name
The .io (Indian Ocean) country-code top-level domain was delegated by the Internet Assigned Numbers Authority (IANA) to British entrepreneur Paul Kane in 1997, and was operated for private benefit under the trade name 'Internet Computer Bureau' from 1997 until 2017.[109] In April 2017, Paul Kane sold the Internet Computer Bureau holding company to privately held domain name registry services provider Afilias for US$70 million in cash.[110]
In July 2021, the Chagos Refugees Group UK submitted a complaint to the Irish government against Paul Kane and Afilias, seeking repatriation of the .io domain, and payment of back royalties from the $7m per year in revenue generated by the domain.[111]
