New Caledonia is a French overseas territory with the status of a *sui generis* collectivity, located in the western Pacific Ocean—in Melanesia—approximately 1,400 km east of Australia and 1,500 km northwest of New Zealand.
Geography. The territory comprises the main island, New Caledonia, along with offshore islands such as the Loyalty Islands, Île des Pins, and the Chesterfield Islands. Residents of European descent often colloquially refer to the territory as *le Caillou* (“the Rock”), while those of Melanesian descent call it *la Kanaky*. The total area of the New Caledonia overseas territory is 18,575.5 km² (with the main island accounting for 16,594.6 km²), and it has a population of 279,070 (2017). The territory’s capital is Nouméa, located in the southern part of the main island. Melanesian Kanaks make up 42.5% of the population, Europeans 37.1%, and Polynesians 11.8%. The interior of the main island is mountainous, featuring the highest peak, Mont Panié, at 1,628 meters above sea level. The climate is tropical with seasonal rainfall: 1,500 mm in the Loyalty Islands, 2,000 mm on the east coast, 4,000 mm in the mountains, and 1,200 mm in the west. New Caledonia is of continental origin, representing a fragment of Gondwana. It first separated from Australia 85 million years ago and from New Zealand 65 million years ago. Isolation from species evolving elsewhere—such as mammals—turned the island into a “Noah’s Ark” for a wide variety of primitive organisms, primarily plants like the *Araucaria*. Of the 3,300 plant species, three-quarters are endemic; the flora also includes five monotypic families, such as Amborellaceae. Before the arrival of humans, the area was inhabited by species such as *Sylviornis neocaledoniae*, a bird standing 1.7 m tall and weighing 30 kg. Currently (as of 2014), 24 endemic bird species live here—including the kagu, the sole member of the family Rhynochetidae—and exactly half of them are at least vulnerable to extinction. Of the 70 reptile species, 62 are endemic. These animals are threatened by introduced and feral rats, cats, dogs, and pigs.
History. The islands were settled around 1500 BC. Around the 11th century AD, Polynesians arrived and intermixed with the indigenous population. New Caledonia was discovered by Europeans in 1774; it was sighted by James Cook. It derives its name from the Latin name for Scotland—Caledonia—following a once-common practice of naming newly discovered territories (as well as newly built settlements) after existing places. It became a French possession in 1853. Between 1864 and 1894, a penal colony operated there, to which many convicted Communards were deported. Among those sentenced to life imprisonment with hard labor in New Caledonia was Antoni Berezowski, a January Uprising insurgent who had attempted to assassinate Tsar Alexander II during the latter’s visit to Paris on June 6, 1867. A decree issued in 1887 curtailed the freedoms of the local population, compelling them to perform state labor and imposing tribal chiefs selected by the state. Between 1898 and 1902, the area of indigenous reserves was reduced from 320,000 to 124,000 hectares. French pressure led to a series of uprisings; the largest, led by Ataï in 1878, resulted in the deaths of approximately 200 Europeans and at least 800 Kanaks. As a result of the changes during the colonial period, the Kanak population fell from between 40,000 and 80,000 in 1774 to 27,000. …people (1921). Under the terms of political agreements with France, the Congress of New Caledonia was granted the right to request the holding of two further independence referendums—one after two years and another after four. The second referendum was scheduled for October 4, 2020. In that referendum, 53.26 percent of New Caledonia’s residents voted against independence, with a turnout of 85.64 percent. A subsequent referendum, held on December 12, 2021, during the COVID-19 pandemic, was boycotted by independence supporters—primarily Kanaks living in the Loyalty Islands and the Northern Province. Consequently, 96.49 percent of votes were cast in favor of remaining associated with France, with a turnout of only 43.9 percent.
Economy. New Caledonia possesses very rich deposits of nickel ore (accounting for approximately 12% of global output—ranking third worldwide—and one-quarter of global reserves) and cobalt (about 8% of global output—ranking fourth). Nouméa is a major center for nickel smelting. However, the extraction of mineral resources has led to environmental degradation in many parts of the island. Beyond the industrial areas, tourism is also developing, attracting around 100,000 visitors annually.
Greenhouse gas emissions. In 1990, New Caledonia’s carbon dioxide equivalent emissions totaled 2.03 Mt, with carbon dioxide emissions accounting for 1.623 Mt. Per capita emissions stood at 9.558 tonnes of carbon dioxide, while emissions per 1,000 dollars of GDP amounted to 556 kg. Since then, emissions have fluctuated, with a significant increase occurring in the early 2010s; the energy sector saw the largest rise in emissions during this period. In 2018, fossil-fuel-derived carbon dioxide emissions totaled 7.337 Mt, equating to 26.221 tonnes per capita and 1,169 kg per 1,000 dollars of GDP.
Demographics. The territory was inhabited by approximately 279,070 people (as of 2022), 45% of whom are Kanaks—the islands’ indigenous people. Other inhabitants include the French (approx. 33.5%), known as *Caldoches* (most of whom were born in New Caledonia), and Polynesians (approx. 10.5%)—comprising residents of Ouvéa Island and migrants from Futuna, Tahiti, and Uvea. The remaining 7.5% consists of smaller groups, including Ni-Vanuatu, Japanese, Italians, English, Australians, Arabs, and others.
Grande Terre is the main and by far the largest island of New Caledonia, a French overseas territory located in the western Pacific Ocean (Melanesia). The island has a distinctive elongated shape and stretches for approximately 400 kilometers, accounting for 88% of the entire archipelago’s land area. Key facts about Grande Terre: Capital and heart of the island: Nouméa lies on the southwestern coast—the territory’s capital and a cosmopolitan city blending the French lifestyle with Melanesian culture. World’s largest lagoon: The island is encircled by a massive barrier reef that creates the world’s second-largest lagoon (after the Great Barrier Reef)—often considered the most beautiful—which has been inscribed on the UNESCO World Heritage List. A geography of contrasts: The Chaîne Centrale mountain range runs through the center of the island, featuring its highest peak, Mont Panié. It divides the island into two vastly different zones: The west coast: Dry and flat, dominated by vast savannas and traditional cattle ranches (owned by *Caldoches*). The east coast: Humid and covered in lush tropical vegetation, featuring picturesque waterfalls and traditional villages of the indigenous Kanak people. Natural wealth: Grande Terre holds some of the world’s largest nickel deposits. The island is also home to an extraordinary number of endemic plant and animal species found nowhere else on Earth.
The New Caledonia coral reef is the second-longest coral reef in the world (surpassed only by Australia’s Great Barrier Reef) and one of the most spectacular marine ecosystems on Earth. This massive barrier system stretches for approximately 1,500–1,700 kilometers across the Coral Sea, encircling the archipelago’s main island, Grande Terre, as well as smaller islands (such as Île des Pins). Key facts about the coral reef. UNESCO listing: In 2008, the lagoons and coral reefs of New Caledonia were inscribed on the UNESCO World Heritage List due to their exceptional beauty and remarkable biodiversity. Vast lagoon: The reef forms a barrier protecting a massive lagoon covering an area of approximately 24,000 km². It is one of the largest enclosed lagoons on the globe, characterized by shallow, crystal-clear turquoise waters. Unique ecosystem: It features a vast diversity of coral structures—ranging from barrier reefs to fringing reefs—and serves as a home to thousands of species of fish, crustaceans, and marine mammals.
Endemic flora and fauna. New Caledonia is one of the most fascinating and unique evolutionary laboratories on Earth, often referred to as a paleontological “Noah’s Ark.” This tropical Pacific island separated from the supercontinent of Gondwana approximately 85 million years ago. Over millions of years of isolation, an ecosystem evolved there that is unlike any other: as many as 75% of the local plants and the vast majority of reptiles are endemic species found nowhere else in the world.
The architecture of New Caledonia is a fascinating synthesis of two worlds: the deeply rooted traditions of the indigenous Kanak people and the European influences stemming from French colonization. This blend of styles has earned the island’s capital, Nouméa, the nickname “the Paris of the Pacific.”
