Population distribution:

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

Environment - current issues:
water needs met by catchment systems; the use of sand as a building material has led to beachhead erosion; deforestation; damage to coral reefs from increasing ocean temperatures and acidification; rising sea levels threaten 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: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Desertification, Law of the Sea, Ozone Layer Protection, Ship Pollution, Whaling
signed, but not ratified: none of the selected agreements

Geography - note:
one of the smallest and most remote countries on Earth; six of the nine 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
