geography Maturity 11-13 Next article →

South Tarawa is the capital and central hub of the Republic of Kiribati.

It serves as the nation's primary center for government, commerce, and education. The area is a string of small islets located on the Tarawa Atoll. These islets sit between the Tarawa Lagoon to the north and the Pacific Ocean to the south. The lagoon reaches a maximum depth of 20 meters. In contrast, the Pacific Ocean to the south can reach depths of up to 3,000 meters.

The physical land of South Tarawa was formed by sediments from the lagoon. This process of soil accumulation is driven by dominant easterly trade winds. However, this process can be reversed during extended periods of westerly winds. These shifts often occur during El Niño–Southern Oscillations. Today, the various islets are connected by causeways. These structures create one long, continuous islet along the southern side of the lagoon. Most of the land is extremely low. It sits less than 3 meters above sea level, with an average width of only 400 meters.

The climate in South Tarawa is classified as a Tropical rainforest climate. This means the environment remains warm and humid throughout the entire year. While average rainfall is relatively high, the patterns are very unpredictable. Rainfall varies significantly with the El Niño–Southern Oscillation. During La Niña cycles, South Tarawa can experience many months with almost no rain. The temperature range is one of the narrowest in the world. The highest recorded temperature was 32°C, while the lowest was 22°C.

Water resources are very limited for the growing population. During frequent droughts, residents must rely on a shallow freshwater lens. This lens of fresh water permeates the coral rock of the atoll. The water lenses at Bonriki and Buota are designated as official water reserves. Together, they have a sustainable yield of 1,300 cubic meters per day. This water is distributed to households through a reticulated network. However, the network is in poor condition. Because of supply limits, water is often only available to villages for about 2 hours every two days.

South Tarawa has a complex administrative structure. In 1972, John Hilary Smith created two administrative subdivisions. One is the Betio Town Council, which covers the area from Bairiki to Tanaea. The other is the Teinainano Urban Council.

The area of Buota is part of North Tarawa but is linked to South Tarawa by road. Buota is administered by the Eutan Tarawa Council. This area is currently experiencing rapid urbanization and environmental degradation similar to South Tarawa.

The history of the region is tied to colonial shifts. Tarawa is central to Kiribati mythology and culture. In 1895, it was selected as the seat of colonial government for the Protectorate of the Gilbert and Ellice Islands. Between 1906 and 1942, Ocean Island served as the colony's headquarters. Later, the headquarters moved to Funafuti due to the Japanese occupation of the Gilbert Islands. The administration finally returned to Tarawa in 1946.

The islet of Betio was also the site of the historic Battle of Tarawa.

Population growth has changed the landscape significantly. In the 1978 Census, South Tarawa had 17,921 residents. Since Kiribati gained independence in 1979, the population has more than tripled. By 2020, the population reached 63,439 people.

The area is now fully urbanized from Tanaea in the northeast to Betio in the southwest. The official land area is 15.76 square kilometers. However, much of this is unavailable for living, such as the runway and water reserves. When excluding these areas, the usable land is just over 1,000 hectares. This results in a density of 49 people per hectare. This density is nearly equal to London and twice that of Sydney or Auckland.

The economy is centered on trade and the ocean. Fishing is essential for both family consumption and commercial sale.

The port at Betio is a major economic hub.

At this port, copra from outer islands is processed into copra oil for international markets. There is also a plant that processes tuna for export. Despite these industries, many residents rely on government employment or money sent from relatives overseas. Unemployment remains a serious challenge, particularly for young people.
