Nauru’s natural environment combines a raised coral island, a coastal plain, a fringing reef, Buada Lagoon, a mined phosphate plateau and the surrounding ocean. These areas support endemic Nauru reed warblers, native birds and plants, reef fish, corals, giant clams and nesting green turtles. The island’s surroundings are strongly shaped by settlement and infrastructure near the coast, limited freshwater, sanitation and waste constraints, and exposure to climate hazards. Freshwater commonly comes from household rainwater tanks, desalination or deliveries by Nauru Utilities Corporation (NUC), rather than from a nationwide piped network. National agencies, communities and households therefore share responsibilities that a municipality might handle elsewhere. Water availability, storage capacity, delivery arrangements and sanitation conditions affect daily life and environmental health. Mining has left extensive pressure on land and contributes to the need for rehabilitation of the phosphate plateau. Pollution, overuse, water stress and climate change also affect terrestrial and marine ecosystems. As of 9 March 2026, no formal terrestrial or marine protected areas are recorded. Higher-ground development, rehabilitation of mined land and resilient infrastructure are intended to reduce exposure, although several planned systems are still being built.
Environment in Nauru
Nauru’s environment includes its natural ecosystems and the built surroundings where people live, obtain water and manage waste. The island’s raised coral land, coast, reef, lagoon and surrounding ocean support distinctive species, while mining, pollution, water stress, sanitation limits and climate hazards create pressure. Coastal settlement and infrastructure make resilient land use and environmental rehabilitation central to Nauru’s future.
