Tuvalu's environment links its land, reefs, lagoons, shallow marine areas and ocean with the places and services used in daily life. The country has about 26 square kilometres of land spread across an island chain roughly 600 kilometres long. Most land rises only 1 to 2 metres above sea level, so coastal exposure affects settlements, infrastructure, freshwater and sanitation. Marine ecosystems support fisheries, food security and income, but warming, coral bleaching, pollution, overfishing, storms and coastal change place pressure on them. Everyday surroundings also include waste management, green and communal spaces, safety systems and opportunities to participate in local decisions. Funafuti, especially Fongafale, experiences stronger pressure from density, scarce land, flooding, erosion, heat and saltwater. Services and infrastructure vary across the outer islands. National programmes and donor-supported projects respond to these conditions, but a planned measure may not yet be available in every location or operating in practice.
Environment in Tuvalu
Environment in Tuvalu covers both natural systems and the conditions in which people live. Nature includes nine low-lying coral atolls and reef islands, while everyday surroundings include homes, infrastructure, freshwater, sanitation, waste services and communal spaces. Environmental pressures differ between Funafuti and the outer islands, but warming, flooding, erosion, saltwater, pollution and limited land affect planning across the country.
