Kiribati's Tuna Fortune Threatened by Warming Seas
27 Apr
Summary
- Kiribati's economy relies heavily on tuna fishing licenses.
- Warming oceans may cause tuna to migrate out of Kiribati's waters.
- Climate change poses an existential threat to the nation's revenue.

The vast Pacific Ocean is a major source of the world's tuna, with Kiribati's islands being a significant hub. Over 70% of Kiribati's government revenue is derived from selling tuna fishing licenses to foreign fleets, a proportion unmatched by any other nation. This income is crucial, as the country has a small landmass but a vast exclusive economic zone (EEZ) of over 3.4 million sq km.
The primary threat to Kiribati's economy is climate change, which is causing ocean temperatures to rise. Scientists fear that tuna may migrate to cooler waters outside Kiribati's EEZ. This migration could reduce demand for fishing licenses, severely impacting the nation's finances. The global tuna market is valued at over $44 billion annually.
