Kiribati: Vanishing Paradise (A Case of Ecological Migration)

Kiribati: Vanishing Paradise

Rising sea level is forcing inhabitants to leave permanently their home islands, a classical example of modern day exodus - ecomigration.

Kiribati main island is formerly Atoll Christmas, named by Captain Cook when he arrived on Christmas Eve in 1777. The island, like most islands in the region, faces irreversible submergence and sea water intrusion as a result of rising sea level brought about by global warming. The island was used as nuclear testing ground by the United States in the fifties and sixties.

The sea has practically swallowed up a whole atoll*, with narrow 
fringes the only remaining habitable portion, at least up to now.

*An atoll is a ring-shaped coral reef, island, or series of islets. An atoll surrounds a body of water called a lagoon. Sometimes, atolls and lagoons protect a central island. Channels between islets connect a lagoon to the open ocean or sea. Atolls develop with underwater volcanoes, called seamounts.

Kiribati (pronounced /ˈkɪrɨbæs or KIRR-i-bas; Gilbertese: [ˈkiɾibas]), is composed of 32 atolls and one raised coral island, dispersed over 3.5 million square kilometres, (1,351,000 square miles) straddling the equator, and bordering the International Date Line at its easternmost point. Kiribati is the only country in the world located on both hemispheres and lying on both sides of the 180th meridian.

The groups of islands are:

* Banaba: an isolated island between Nauru and the Gilbert Islands
* Gilbert Islands: 16 atolls located some 930 miles (1,500 km) north of Fiji
* Phoenix Islands: 8 atolls and coral islands located some 1,100 miles (1,800 km) southeast of the Gilberts
* Line Islands: 8 atolls and one reef, located about 2,050 miles (3,300 km) east of the Gilberts.

Used for nuclear testing in the 1950s and 1960s, the island is now valued for its marine and wildlife resources. It is particularly important as a seabird nesting site—with an estimated 6 million birds using or breeding on the island, including several million Sooty Terns.

According to the South Pacific Regional Environment Program, two small uninhabited Kiribati islets, Tebua Tarawa and Abanuea, disappeared underwater in 1999. The islet of Tepuka Savilivili no longer has any coconut trees due to salination. The UN Intergovernmental Panel on Climate Change predicts that sea levels will rise by about half a metre (20 in) by 2100 due to global warming and a further rise would be inevitable. It is thus likely that within a century the nation's arable land will become subject to increased soil salination and will be largely submerged.

Rising level level is also being felt in many countries, particularly island-countries like the Philippines. ~

Kiribati, officially the Republic of Kiribati, is an island country in the Micronesia subregion of Oceania in the central Pacific Ocean. Its permanent population is over 119,000 as of the 2020 census, with more than half living on Tarawa atoll. The state comprises 32 atolls and one remote raised coral island, Banaba. Wikipedia

Official name: Republic of Kiribati.
Capital city: Tarawa.
Population: 135,389.
Area: 811 sq km.
Major languages: I-Kiribati, English.
Time zone: UTC+12/+13/+14 (Gilbert Island Time/Phoenix Island
     Time/Line Islands Time)
      • Economy- Until 1979, when Banaba’s deposit of phosphate rock was exhausted, Kiribati’s economy depended heavily on the export of phosphate mineral. Before the cessation of mining, a large reserve fund was accumulated; the interest now contributes to government revenue. Other revenue earners are copra, mostly produced in the village economy, and license fees from foreign fishing fleets, including a special tuna-fishing agreement with the European Union. Commercial seaweed farming has become an important economic activity. Internet
