Tonga
Tonga, an upper-middle-income country located in the South Pacific Ocean, has benefited from strong average economic growth since 2017. Its 100,000 citizens have experienced a sharp increase in life expectancy since the 1960s, and over half of its population is of school age. The 176-island archipelago of Tonga is exposed to a range of natural hazards, including cyclones, earthquakes, tsunamis, and volcanoes. Estimated annual losses from these hazards are on average equivalent to 4.4 percent of the country’s gross domestic product (GDP). In February 2018, Tropical Cyclone Gita affected almost 75 percent of Tonga’s population and caused damage and losses of US$164.1 million, amounting to 37.8 percent of the country’s GDP. Tonga is also vulnerable to the growing geographical, geological, and socioeconomic impacts of climate change.
