- Geography_of_Tuvalu abstract "The Western Pacific nation of Tuvalu, formerly known as the Ellice Islands, is situated 4,000 kilometers (2,500 mi) northeast of Australia. It is one half of the way from Hawaii to Australia. Tuvalu consists of three reef islands and six atolls. The islands of Tuvalu have poor soil and a total land area of only about 26 km², less than 10 sq mi (30 km2).Tuvalu has westerly gales and heavy rain from November to March and tropical temperatures moderated by easterly winds from April to November. The land is very low-lying, with narrow coral atolls. The highest elevation is 4.6 metres (15 ft) above sea level on Niulakita.Location:Oceania, island group of nine islands comprising three reef islands and six true atolls in the South Pacific Ocean, about one-half of the way from Hawaii to Australia. The islands of Tuvalu are spread out between the latitude of 5° to 10° south and longitude of 176° to 180°, west of the International Date Line.Geographic coordinates: 5°41′S 176°12′E to 10°45′S 179°51′EMap references:OceaniaArea:total:26 km²land:26 km²water:0 km²Area - comparative:0.1 times the size of Washington, DCLand boundaries:0 kmCoastline:24 kilometres (15 mi)Maritime claims:contiguous zone:24 nmi (44 km)exclusive economic zone:200 nmi (370 km)territorial sea:12 nmi (22 km)Tuvalu’s Exclusive Economic Zone (EEZ) covers an oceanic area of approximately 900,000 km2.Climate:tropical; moderated by easterly trade winds (March to November); westerly gales and heavy rain (November to March)Terrain:low-lying and narrow coral atollsElevation extremes:lowest point:Pacific Ocean 0 mhighest point:unnamed location, 4.6 metres (15 ft) on NiulakitaExtreme points:This is a list of the extreme points of Tuvalu, the points that are farther north, south, east or west than any other location. Northernmost point – Lakena islet, Nanumea Easternmost point – Niuoko islet, Nukulaelae Southernmost point – Niulakita Westernmost point - Lakena islet, NanumeaNatural resources:fishLand use:arable land:0%permanent crops:60%other:40% (2011)Irrigated land:NA km²Natural hazards:Severe tropical cyclones are usually rare, however the low level of islands makes them very sensitive to sea-level rise. George Westbrook, a trader on Funafuti, recorded a cyclone that struck Funafuti in 1883. A cyclone caused severe damage to the islands in 1894. Nui was struck by a giant wave on 16 February 1882; earthquakes and volcanic eruptions occurring in the basin of the Pacific Ocean - the Pacific Ring of Fire - are a possible cause of a Tsunami.Cyclone Bebe caused severe damage to Funafuti during the 1972-1973 cyclone season. Funafuti’s Tepuka Vili Vili islet was devastated by Cyclone Meli in 1979, with all its vegetation and most of its sand swept away during the cyclone. Cyclone Gavin was first identified during 2 March 1997, and was the first of three tropical cyclones to affect Tuvalu during the 1996-97 cyclone season with Cyclones Hina and Keli following later in the season. Cyclone Ofa had a major impact on Tuvalu in January 1990. On Vaitupu Island around 85 percent of residential homes, trees and food crops were destroyed, while residential homes were also destroyed on the islands of Niutao, Nui and Nukulaelae. The majority of the islands in Tuvalu reported damage to vegetation and crops especially bananas, coconuts and breadfruit, with the extent of damage ranging from 10 to 40 percent. In Funafuti sea waves flattened the Hurricane Bebe bank at the southern end of the airstrip, which caused sea flooding and prompted the evacuation of several families from their homes. In Nui and Niulakita there was a minor loss of the landscape because of sea flooding while there were no lives lost. Soon after the systems had impacted Tuvalu, a Disaster Rehabilitation Sub-Committee was appointed to evaluate the damage caused and make recommendations to the National Disaster Committee and to the Cabinet of Tuvalu, on what should be done to help rehabilitate the affected areas.Environment - current issues:since there are no streams or rivers and groundwater is not potable, most water needs must be met by catchment systems with storage facilities; beachhead erosion because of the use of sand for building materials; excessive clearance of forest undergrowth for use as fuel; damage to coral reefs from the bleaching of the coral as a consequence of the increase of the ocean temperatures and acidification from increased levels of carbon dioxide; Tuvalu is very concerned about global increases in greenhouse gas emissions and their effect on rising sea levels, which threaten the country's underground water table.El Niño and La Niña:Tuvalu experiences the effects of El Niño and La Niña that flow from changes in ocean temperatures in equatorial and central Pacific. El Niño effects increase the chances of tropical storms and cyclones; while La Niña effects increase the chances of drought conditions in Tuvalu. On 3 October 2011, drought conditions resulted in a state of emergency being declared as water reserves ran low. Typically the islands of Tuvalu receive between 200mm to 400mm of rainfall per month, however a weak La Niña effect caused a drought by cooling the surface of the sea around Tuvalu.Environment - international agreements:party to:Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Law of the Sea, Ozone Layer Protection, Ship Pollution, Whalingsigned, but not ratified: none".
