Natural resources: fish
Land use: arable land: 0% permanent crops: 0% other: 100% (1998 est.)
Irrigated land:
NA sq km
Natural hazards:
severe tropical storms are usually rare, but, in 1997, there were
three cyclones; low level of islands make them very sensitive to
changes in sea level
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; in 2000, the government appealed to
Australia and New Zealand to take in Tuvaluans if rising sea levels
should make evacuation necessary
Environment - international agreements:
party to: Climate Change, Climate Change-Kyoto Protocol,
Desertification, Ozone Layer Protection, Ship Pollution
signed, but not ratified: Biodiversity, Law of the Sea
Geography - note:
one of the smallest and most remote countries on Earth; six of the
coral atolls - Nanumea, Nui, Vaitupu, Nukufetau, Funafuti, and
Nukulaelae - have lagoons open to the ocean; Nanumaya and Niutao
have landlocked lagoons; Niulakita does not have a lagoon
