Why did Kiribati purchase land on Vanua Levu in Fiji in 2014?

In 2014, the government of Kiribati purchased approximately 8 square miles (20 square km) of land on the Fijian island of Vanua Levu as a proactive measure against the threats posed by climate change.12

Rising sea levels threaten to contaminate and eventually submerge the nation's low-lying islands, making them potentially uninhabitable. The acquisition serves two primary purposes:12
* Future Security: The land provides a potential new homeland for the citizens of Kiribati should relocation become necessary.12
* Interim Utility: In the meantime, the property is intended to be used for supplemental food production to support the country's needs.12
