Geography of Tuvalu

From Wikipedia, the free encyclopedia

The Western Pacific nation of Tuvalu, formerly known as the Ellice Islands, is situated 4,000 kilometers (2,486 miles) northeast of Australia. It is one half of the way from Hawaii to Australia. Tuvalu consists of four reef islands and five true atolls (see Islands of Tuvalu). Its small scattered group of atolls has 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 March-November. The land is very low lying with narrow coral atolls. The highest elevation is five meters above the sea level.

Location: Oceania, island group consisting of nine coral atolls in the South Pacific Ocean, about one-half of the way from Hawaii to Australia.

Natural hazards: severe tropical storms are usually rare, but, in 1997, there were three cyclones; low-level of islands make them very sensitive to sea-level rise

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 (the Japanese Government has built one desalination plant and plans to build one other); 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 spread of the Crown of Thorns starfish; 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
