Tuamotu

The Tuamotu Archipelago or the Tuamotu Islands (french: Îles Tuamotu, officially ) are a French Polynesian chain of just under 80 islands and atolls in the southern Pacific Ocean. They constitute the largest chain of atolls in the world, extending (from northwest to southeast) over an area roughly the size of Western Europe. Their combined land area is . This archipelago's major islands are Anaa, Fakarava, Hao and Makemo.

The Tuamotus have approximately 16,000 inhabitants. The islands were initially settled by Polynesians, and modern Tuamotuans have inherited from them a shared culture and the Tuamotuan language.

The Tuamotus are a French overseas collectivity.

History

The early history of the Tuamotu islands is generally unknown. Archaeological findings suggest that the western Tuamotus were settled from the Society Islands as early as 900 CE or as late as 1200 CE. DNA evidence suggests that they were settled about 1110 CE. On the islands of Rangiroa, Manihi and Mataiva, there are flat ceremonial platforms (called ''marae'') made of coral blocks, although their exact age is unknown.

The first known European encounter with the Tuamotus was with the Portuguese sailor Ferdinand Magellan, during his circumglobal voyage in 1521, undertaken in the service of the Spanish Crown. His encounter was followed by visits from several other Europeans, including:
*Portuguese sailor Pedro Fernandes de Queirós in 1606, sailing in the service of the Spanish Crown;
*Dutch mariners Willem Schouten and Jacob Le Maire in 1616;
* Jacob Roggeveen (who also first sighted Easter Island) in 1722;
* John Byron in 1765;
*Louis Antoine de Bougainville in 1768;
* James Cook during his first voyage in 1769;
*Spanish navigator Domingo de Bonechea in 1774 and
*Russian expedition of Otto von Kotzebue in 1815.
None of these visits were of political consequence, as the islands were within the sphere of influence of the Pōmare Dynasty of Tahiti.

The first Christian missionaries arrived in the islands at the beginning of the 19th century. By the late 19th century, traders had begun offering pearls from the islands for sale in Europe, and they became coveted possessions there. France forced the abdication of King Pōmare V of Tahiti and claimed the islands, but did not formally annex them.

Robert Louis Stevenson and Fanny Stevenson travelled among the Taumotus (then called the Paumotus) on the yacht ''Casco'' in 1888; an account of their journey was published as ''In the South Seas''. Jack London wrote a story, " The Seed of McCoy", based on an incident in 1900 in which a burning ship, the ''Pyrenees'', had been safely beached on Mangareva. In the story, London has the ship sail past Mangareva and all through the Tuamotus before beaching on Fakarava.

The Tuamotus made headlines around the world in 1947, when the Norwegian ethnographer Thor Heyerdahl, sailing from South America with a crew of five others, reached Raroia on his raft '' Kon-Tiki''. The islands were in the news again somewhat later, when France conducted nuclear weapons testing on the atolls of Moruroa and Fangataufa.

Administrative divisions

French Polynesia is a semi-autonomous island group designated as an overseas country of France. The Tuamotus combine with the Gambier Islands to form the '' Îles Tuamotu-Gambier'' which is one of the five administrative divisions of French Polynesia.

The Tuamotus are grouped into sixteen communes: Anaa; Arutua; Fakarava; Fangatau; Hao; Hikueru; Makemo; Manihi; Napuka; Nukutavake; Puka Puka; Rangiroa; Reao; Takaroa; Tatakoto; and Tureia.

Electoral divisions

The communes on Tuamotu are part of two different electoral districts (''circonscriptions électorales'') represented in the Assembly of French Polynesia. The electoral district called ''Îles Gambier et Tuamotu Est'' comprises the commune of Gambier and eleven communes in eastern Tuamotu: Anaa, Fangatau, Hao, Hikueru, Makemo, Napuka, Nukutavake, Pukapuka, Reao, Tatakoto, and Tureia. The other five communes in western Tuamotu – Arutua, Fakarava, Manihi, Rangiroa, and Takaroa – form the electoral district called ''Îles Tuamotu Ouest''.

Geography

Despite the vast spread of the archipelago, it covers a total land area of only about . The climate is a warm tropical one, without sharply distinct seasons. The average annual temperature is a relatively continuous . Water sources such as lakes or rivers are absent, leaving catchments of rain as the only source of fresh water. The annual average rainfall is . Although average rainfall is lowest in September and November, it does not vary markedly throughout the year.

The archipelago is geologically highly stable, because it was created by the action of the Easter Fracture Zone, which is only weakly active. There have been no volcanic eruptions during recorded history.

Flora and fauna

The sparse soil of the coral islands does not support diverse vegetation. The coconut palm, which is the basis of copra production, is of special economic importance. On a few of the islands, vanilla is also cultivated. Agriculture is generally otherwise limited to simple subsistence. Fruit and vegetable staples include yams, taro, breadfruit, and a wide range of tropical fruit. Pandanus leaves are traditionally woven together to make mats, hats, and roof thatches. However, many of the roofs nowadays are made of corrugated sheet-metal.

The species-rich reefs are home to a diverse range of underwater fauna. The surface creatures are primarily seabirds, insects, and lizards. The Tuamotus have 86 species of birds, ten of which are endemic, including the Tuamotu kingfisher, the Tuamotu reed warbler, and the Tuamotu sandpiper. Thirteen species are globally threatened, and one has gone extinct.

Geology

All of the islands of the Tuamotus are coral "low islands": essentially high sand bars built upon coral reefs. Makatea, southwest of the Palliser Islands, is one of three great phosphate rocks in the Pacific Ocean. (The others are Banaba in Kiribati, and the island nation of Nauru.) Although the Gambier Islands are geographically part of the Tuamotus because they lie at the southeastern extreme of the archipelago, they are geologically and culturally distinct.

The ring-shaped atoll Taiaro, which lies in the northwestern portion of the archipelago, is a rare example of a coral reef that has a fully enclosed lagoon. Taiaro has been officially designated a UNESCO biosphere reserve since 1977.
