Global warming and rising sea levels are increasingly causing major problems for low lying Pacific and Indian Ocean island nations. This paper describes a sustainable artificial island, designed for the inhabitants of South Tarawa, a coral atoll in the South Pacific and the capital island of the Republic of Kiribati. Design targets were to improve infrastructure, services and quality of life for the inhabitants, to increase island sustainability and to minimise construction costs. Transition to an artificial island is a feasible option with significant international support, and would enable survival for the population of South Tarawa with minimum disruption to their current lifestyle.
