Geography

The total land area of the country is 2,040 km2 (790 sq mi). It is the 170th largest nation in the world by size. The Republic of Mauritius is constituted of Mauritius Island and several outlying islands. The nation's exclusive economic zone (EEZ) covers about 2.3 million km2 (890,000 sq mi) of the Indian Ocean, including approximately 400,000 km2 (150,000 sq mi) jointly managed with the Seychelles.

Mauritius Islandedit

Mauritius is 2,000 km (1,200 mi) off the southeast coast of Africa, between latitudes 19°58.8'S and 20°31.7'S and longitudes 57°18.0'E and 57°46.5'E. It is 65 km (40 mi) long and 45 km (30 mi) wide. Its land area is 1,864.8 km2 (720.0 sq mi). The island is surrounded by more than 150 km (100 mi) of white sandy beaches, and the lagoons are protected from the open sea by the world's third-largest coral reef, which surrounds the island. Just off the Mauritian coast lie some 49 uninhabited islands and islets, several of which have been declared natural reserves for endangered species.

The Mauritius Island (Mauritian Creole: Isle Moris; French: Île Maurice, pronounced il mɔʁis) is relatively young geologically, having been created by volcanic activity some 8 million years ago. Together with Saint Brandon, Réunion, and Rodrigues, the island is part of the Mascarene Islands. These islands emerged as a result of gigantic underwater volcanic eruptions that happened thousands of kilometres to the east of the continental block made up of Africa and Madagascar. They are no longer volcanically active and the hotspot now rests under Réunion Island. Mauritius is encircled by a broken ring of mountain ranges, varying in height from 300–800 m (1,000–2,600 ft) above sea level. The land rises from coastal plains to a central plateau where it reaches a height of 670 m (2,200 ft); the highest peak is in the south-west, Piton de la Petite Rivière Noire at 828 metres (2,717 ft). Streams and rivers speckle the island, many formed in the cracks created by lava flows.

Rodrigues Islandedit

The autonomous island of Rodrigues is located 560 km (350 mi) to the east of Mauritius, with an area 108 km2 (42 sq mi). Rodrigues is a volcanic island rising from a ridge along the edge of the Mascarene Plateau. The island is hilly with a central spine culminating in the highest peak, Mountain Limon at 398 m (1,306 ft). The island also has a coral reef and extensive limestone deposits. According to Statistics Mauritius, at 1 July 2019, the population of the island was estimated at 43,371.

Chagos Archipelagoedit

The Chagos Archipelago is composed of atolls and islands, and is located approximately 2,200 kilometres north-east of the main island of Mauritius. To the north of the Chagos Archipelago are Peros Banhos, the Salomon Islands and Nelsons Island; to the south-west are The Three Brothers, Eagle Islands, Egmont Islands and Danger Island. Diego Garcia is in the south-east of the Archipelago. In 2016, the Chagossian population was estimated at 8,700 in Mauritius, including 483 natives; 350 Chagossians live in the Seychelles, including 75 natives, while 3,000, including 127 natives, live in the UK (the population having grown from the 1200 Chagossians who moved there).

St. Brandonedit

St. Brandon, also known as Cargados Carajos Shoals, is located 402 kilometres (250 mi) northeast of Mauritius Island. The archipelago consists of 16 Islands and Islets. Saint Brandon consists of five island groups, with about 28–40 islands and islets in total, depending on seasonal storms and related sand movements.

Agaléga Islandsedit

The twin islands of Agaléga are located some 1,000 kilometres (600 miles) to the north of Mauritius. Its North Island is 12.5 km (7 3⁄₄ mi) long and 1.5 km (7⁄₈ mi) wide, while its South Island is 7 by 4.5 km (4 1⁄₄ by 2 3⁄₄ mi). The total area of both islands is 26 km2 (10 sq mi). According to Statistics Mauritius, at 1 July 2019, the population of Agaléga and St. Brandon was estimated at 274.

Tromelinedit

Tromelin island lies 430 km north-west of Mauritius. Mauritius claims sovereignty over Tromelin island, as does France.

The French took control of Mauritius in 1715, renaming it Isle de France. France officially ceded Mauritius including all its dependencies to Britain through the Treaty of Paris, signed on 30 May 1814 and in which Réunion was returned to France. The British Colony of Mauritius consisted of the main island of Mauritius along with its dependencies Rodrigues, Agalega, St Brandon, Tromelin (disputed) and the Chagos Archipelago, while the Seychelles became a separate colony in 1906. It is disputed whether the transfer of Isle de France (As Mauritius was previously known under French rule) and its dependencies to Britain in 1814 included Tromelin island. Article 8 of the Treaty of Paris stipulate the cession by France to Britain of Isle de France "and its dependencies, namely Rodrigues and the Seychelles". France considers that the sovereignty of Tromelin island was never transferred to Britain. Mauritius claims is based on the fact that the transfer of Isle de France and its dependencies to Britain in 1814 was general, it was beyond those called “namely” in the Treaty of Paris, all the dependencies of Isle de France were not specifically mentioned in the Treaty. Mauritius claim that since Tromelin was a dependency of Isle de France, it was 'de facto' transferred to Britain in 1814. In addition, the islands of Rodrigues, Agalega, St Brandon and the Chagos Archipelago were also not specifically mentioned in the Treaty of Paris but became part of the British Colony of Mauritius as they were dependencies of Isle de France at that time. In addition, the British authorities in Mauritius have been taking administrative measures with respect to Tromelin over the years, for instance, British officials granted four guano operating concessions on Tromelin island between 1901 and 1951. In 1959, British officials in Mauritius informed the World Meteorological Organization that it considered Tromelin to be part of its territory. A co-management treaty was reached by France and Mauritius in 2010 but has not been ratified.

Districts of Mauritius Islandedit

Mauritius is subdivided into nine Districts, they consist of different cities, towns and villages.

Territorial disputesedit

Chagos Archipelagoedit

Mauritius has long sought sovereignty over the Chagos Archipelago, located 1,287 km (800 mi) to the north-east. Chagos was administratively part of Mauritius from the 18th century when the French first settled the islands. All of the islands forming part of the French colonial territory of Isle de France (as Mauritius was then known) were ceded to the British in 1810 under the Act of Capitulation signed between the two powers. In 1965, three years before the independence of Mauritius, the United Kingdom split the Chagos Archipelago from Mauritius and the islands of Aldabra, Farquhar and Desroches from the Seychelles to form the British Indian Ocean Territory (BIOT). The islands were formally established as an overseas territory of the United Kingdom on 8 November 1965. On 23 June 1976, Aldabra, Farquhar and Desroches were returned to Seychelles as a result of its attaining independence. The BIOT now comprises the Chagos Archipelago only. The UK leased the main island of the archipelago, Diego Garcia, to the United States under a 50-year lease to establish a military base. In 2016, Britain unilaterally extended the lease to the US till 2036. Mauritius has repeatedly asserted that the separation of its territories is a violation of United Nations resolutions banning the dismemberment of colonial territories before independence and claims that the Chagos Archipelago, including Diego Garcia, forms an integral part of the territory of Mauritius under both Mauritian law and international law. After initially denying that the islands were inhabited, British officials forcibly expelled to the mainland approximately 2,000 Chagossians who had lived on those islands for a century. To force the inhabitants to leave, first the British authorities cut off food supplies, and those who resisted were threatened with being shot or bombed if they did not leave the island. To frighten them, their dogs and pets were cruelly gassed to death. At the United Nations and in statements to its Parliament, the UK pretended that there was no "permanent population" in the Chagos Archipelago and described the population as mere "contract labourers" who were relocated. Since 1971, only the atoll of Diego Garcia is inhabited, home to some 3,000 UK and US military and civilian contracted personnel. Chagossians have since engaged in activism to return to the archipelago, claiming that their forced expulsion and dispossession were illegal.

Section 111 of the Constitution of Mauritius states that “Mauritius” includes –

(a) the Islands of Mauritius, Rodrigues, Agalega, Tromelin, Cargados Carajos and the Chagos Archipelago, including Diego Garcia and any other island comprised in the State of Mauritius;

(b) the territorial sea and the air space above the territorial sea and the islands specified in paragraph (a);

(c) the continental shelf; and

(d) such places or areas as may be designated by regulations made by the Prime Minister, rights over which are or may become exercisable by Mauritius.

Mauritius considers the territorial sea of the Chagos Archipelago and Tromelin island as part of its Exclusive Economic Zone.

Permanent Court of Arbitrationedit

On 20 December 2010, Mauritius initiated proceedings against the United Kingdom under the United Nations Convention on the Law of the Sea (UNCLOS) to challenge the legality of the Chagos Marine Protected Area (MPA), which the UK purported to declare around the Chagos Archipelago in April 2010. The dispute was arbitrated by the Permanent Court of Arbitration.

The sovereignty of Mauritius was explicitly recognized by two of the arbitrators and denied by none of the other three. Three members of the Tribunal found that they did not have jurisdiction to rule on that question; they expressed no view as to which of the two States has sovereignty over the Chagos Archipelago. Tribunal Judges Rüdiger Wolfrum and James Kateka held that the Tribunal did have jurisdiction to decide this question, and concluded that UK does not have sovereignty over the Chagos Archipelago. They found that:

• internal United Kingdom documents suggested an ulterior motive behind the MPA, noting disturbing similarities and a common pattern between the establishment of the so-called "BIOT" in 1965 and the proclamation of the MPA in 2010;
• the excision of the Chagos Archipelago from Mauritius in 1965 shows a complete disregard for the territorial integrity of Mauritius by the UK;
• UK Prime Minister Harold Wilson's threat to Premier Sir Seewoosagur Ramgoolam in 1965 that he could return home without independence if he did not consent to the excision of the Chagos Archipelago amounted to duress; Mauritian Ministers were coerced into agreeing to the detachment of the Chagos Archipelago, which violated the international law of self-determination;
• the MPA is legally invalid.

The Tribunal's decision determined that the UK's undertaking to return the Chagos Archipelago to Mauritius gives Mauritius an interest in significant decisions that bear upon possible future uses of the Archipelago. The result of the Tribunal's decision is that it is now open to the Parties to enter into the negotiations that the Tribunal would have expected prior to the proclamation of the MPA, with a view to achieving a mutually satisfactory arrangement for protecting the marine environment, to the extent necessary under a "sovereignty umbrella".

International Court of Justiceedit

Amendment of exclusion clause by UKedit

In 2004, following the decision of the British government to promulgate the British Indian Ocean Territory Order, which prohibited the Chagossians from remaining on the islands without express authorisation, Mauritius contemplated recourse to the International Court of Justice to finally and conclusively settle the dispute. However, article 36 of the International Court of Justice Statute provides that it is the option of the state whether it wishes to subject itself to the court's jurisdiction. Where the state chooses to be so bound, it may also restrict or limit the jurisdiction of the court in a number of ways. The UK's clause deposited at the court excluded, amongst other things, the jurisdiction of the court with regard "to any disputes with the government of any country which is a member of the Commonwealth with regard to situations or facts existing before 1 January 1969". The temporal limitation of 1 January 1969 was inserted to exclude all disputes arising during decolonisation. The effect of the British exclusionary clause would thus have prevented Mauritius from resorting to the court on the Chagos dispute because it is a member of the Commonwealth. When Mauritius threatened to leave the Commonwealth, the United Kingdom quickly amended its exclusion clause to exclude any disputes between itself, Commonwealth States and former Commonwealth States, thereby quashing any Mauritian hopes to ever have recourse to the contentious jurisdiction of the court, even if it left.

Advisory opinionedit

On 22 June 2017, by a margin of 94 to 15 countries, the UN General Assembly asked the International Court of Justice to give an advisory opinion on the separation of the Chagos Archipelago from Mauritius before the country's independence in the 1960s. In September 2018, the International Court of Justice began hearings on the case. 17 countries have argued in favour of Mauritius. The UK apologised for the "shameful" way islanders were evicted from the Chagos Archipelago but were insistent that Mauritius was wrong to bring the dispute over sovereignty of the strategic atoll group to the United Nations’ highest court. The UK and its allies argued that this matter should not be decided by the court but should be resolved through bilateral negotiations, while bilateral discussions with Mauritius have been unfruitful over the past 50 years.

On 25 February 2019, the judges of the International Court of Justice by thirteen votes to one stated that the United Kingdom is under an obligation to bring to an end its administration of the Chagos Archipelago as rapidly as possible. Only the American judge, Joan Donoghue, voted in favor of the UK. The president of the court, Abdulqawi Ahmed Yusuf, said the detachment of the Chagos Archipelago in 1965 from Mauritius had not been based on a "free and genuine expression of the people concerned." "This continued administration constitutes a wrongful act," he said, adding "The UK has an obligation to bring to an end its administration of the Chagos Archipelago as rapidly as possible and that all member states must co-operate with the United Nations to complete the decolonization of Mauritius."

On 1 May 2019, the UK Foreign Office minister Alan Duncan stated that Mauritius has never held sovereignty over the archipelago and the UK does not recognise its claim. He stated that the ruling was merely an advisory opinion and not a legally binding judgment. Jeremy Corbyn, leader of the UK's main opposition party, wrote to the UK PM condemning her decision to defy a ruling of the UN's principal court that concluded that Britain should hand back the Chagos Islands to Mauritius. He expressed his concern that the UK government appears ready to disregard international law and ignore a ruling of the international court and the right of the Chagossians to return to their homes.

On 22 May 2019, the United Nations General Assembly debated and adopted a resolution that affirmed that the Chagos Archipelago, which has been occupied by the UK for more than 50 years, "forms an integral part of the territory of Mauritius". The resolution gives effect to an advisory opinion of the International Court of Justice (ICJ), demanded that the UK "withdraw its colonial administration ... unconditionally within a period of no more than six months". 116 states voted in favour of the resolution, 55 abstained and only Australia, Hungary, Israel and Maldives supported the UK and US. During the debate, the Mauritian Prime Minister described the expulsion of Chagossians as "a crime against humanity". While the resolution is not legally binding, it carries significant political weight since the ruling came from the UN's highest court and the assembly vote reflects world opinion. The resolution also has immediate practical consequences: the UN, its specialised agencies, and all other international organisations are now bound, as a matter of UN law, to support the decolonisation of Mauritius even if the UK claim that it has no doubt about its sovereignty.

Biodiversityedit

The country is home to some of the world's rarest plants and animals, but human habitation and the introduction of non-native species have threatened its indigenous flora and fauna. Due to its volcanic origin, age, isolation, and unique terrain, Mauritius is home to a diversity of flora and fauna not usually found in such a small area. Before the Portuguese arrival in 1507, there were no terrestrial mammals on the island. This allowed the evolution of a number of flightless birds and large reptile species. The arrival of humans saw the introduction of invasive alien species, the rapid destruction of habitat and the loss of much of the endemic flora and fauna. Less than 2% of the native forest now remains, concentrated in the Black River Gorges National Park in the south-west, the Bambous Mountain Range in the south-east, and the Moka-Port Louis Ranges in the north-west. There are some isolated mountains, Corps de Garde, Le Morne Brabant, and several offshore islands, with remnants of coastal and mainland diversity. Over 100 species of plants and animals have become extinct and many more are threatened. Conservation activities began in the 1980s with the implementation of programmes for the reproduction of threatened bird and plant species as well as habitat restoration in the national parks and nature reserves.

In 2011, the Ministry of Environment & Sustainable Development issued the "Mauritius Environment Outlook Report," which recommended that St Brandon be declared a Marine Protected Area.

In the President's Report of the Mauritian Wildlife Foundation dated March 2016, St Brandon is declared an official MWF project in order to promote the conservation of the atoll.

The Mauritian Flying Fox is the only remaining mammal endemic to the island, and has been severely threatened in recent years due to the government sanctioned culling introduced in November 2015 due to the belief that they were a threat to fruit plantations. Prior to 2015 the lack of severe cyclone had seen the fruit bat population increase and the status of the species was then changed by the IUCN from Endangered to Vulnerable in 2014. October 2018, saw the authorisation of the cull of 20% of the fruit bat population, amounting to 13,000 of the estimated 65,000 fruit bats remaining, although their status had already reverted to Endangered due to the previous years' culls.

The Dodoedit

When it was discovered, Mauritius was the home of a previously unknown species of bird, the dodo, descendants of a type of pigeon which settled in Mauritius over four million years ago. With no predators to attack them, they had lost their ability to fly. The Portuguese discovered the island around 1505 and the island quickly became a stopover for ships engaged in the spice trade. Weighing up to 23 kg (50 lb), the dodo was a welcome source of fresh meat for the sailors. Large numbers of dodos were killed for food. Later, when the Dutch used the island as a penal colony, new species were introduced to the island. Rats, pigs, and monkeys ate dodo eggs in the ground nests. The combination of human exploitation and introduced species significantly reduced the dodo population. Within 100 years of the arrival of humans on Mauritius, the once abundant dodo became a rare bird. The last one was killed in 1681. The dodo is prominently featured as a (heraldic) supporter of the national coat of arms of Mauritius.

Environment and climateedit

The environment in Mauritius is typically tropical in the coastal regions with forests in the mountainous areas. Seasonal cyclones are destructive to its flora and fauna, although they recover quickly. Mauritius ranked second in an air quality index released by the World Health Organization in 2011.

Situated near the Tropic of Capricorn, Mauritius has a tropical climate. There are 2 seasons: a warm humid summer from November to April, with a mean temperature of 24.7 °C (76.5 °F) and a relatively cool dry winter from June to September with a mean temperature of 20.4 °C (68.7 °F). The temperature difference between the seasons is only 4.3 °C (7.7 °F). The warmest months are January and February with average day maximum temperature reaching 29.2 °C (84.6 °F) and the coolest months are July and August with average overnight minimum temperatures of 16.4 °C (61.5 °F). Annual rainfall ranges from 900 mm (35 in) on the coast to 1,500 mm (59 in) on the central plateau. Although there is no marked rainy season, most of the rainfall occurs in summer months. Sea temperature in the lagoon varies from 22–27 °C (72–81 °F). The central plateau is much cooler than the surrounding coastal areas and can experience as much as double the rainfall. The prevailing trade winds keep the east side of the island cooler and bring more rain. Occasional tropical cyclones generally occur between January and March and tend to disrupt the weather for about three days, bringing heavy rain.

Prime Minister Pravind Jugnauth declared an environmental state of emergency after the July 25, 2020 MV Wakashio oil spill. France sent aircraft and specialists from Réunion and Greenpeace said that the leak threatened the survival of thousands of species, who are at "risk of drowning in a sea of pollution".
