An important development from the financial markets: How climate change threatens the economic backbone of the Pacific 4 days ago Share Save Add as preferred on Google Jacob Evans World Service MFOR Large fishing ships from around the world currently catch tuna in Kiribati's Exclusive Economic Zone The vast Pacific Ocean and the islands dotted within it produce more than half of the world's tuna. Among the islands are 33 scattered across the centre that encompass the country of Kiribati. Here more than 70% of government revenues come from selling tuna fishing licenses to foreign fleets - the highest proportion of any nation.
Kiribati has a tiny land mass. When all the islands are combined it is about the size of New York City. However, it has a huge swathe of territorial waters, otherwise known as its Exclusive Economic Zone (EEZ).
Economic Details
Totalling more than 3. 3m sq miles), the EEZ is spread across three separate parts, surrounding the country's three groups of islands - Gilbert, Phoenix and Line. Collectively, this area is bigger than India and offers access to an ocean abundant with marine life, including skipjack, yellowfin and bigeye tuna.

Warming water temperatures caused by climate change pose a substantial risk to local tuna populations, threatening Kiribati's economic backbone. Scientists fear warmer waters could lead to tuna moving permanently out of its EEZ to cooler temperatures to the east, reducing the demand from overseas fleets for its fishing licenses, which would badly hit the country's economy.
The global tuna market is worth more than $44bn a year, according to one study. To fish in Kiribati's waters, foreign fleets must first obtain a licence from the government. Then they have to pay the required fees, and follow strict rules on catch limits and reporting hauls.

The majority of these licences are sold to countries like Japan, China, the US and members of the European Union. Kiribati generated $137m (£102m) from selling fishing licenses in 2024, government figures showed. This income is a "critical financial lifeline", says Riibeta Abeta, permanent secretary for the country's Ministry of Fisheries.
Abeta adds that such licenses contributed to almost three-quarters of government income between 2018 and 2022. This equates to roughly two-fifths of the entirety of Kiribati's GDP, according to the International Monetary Fund. "Next time you go into the supermarket and you look at the cans of tuna, five-and-a half cans out of 10 stacked up are coming from the Western Central Pacific Ocean ," says Simon Diffey.
He is a fisheries specialist with more than 30 years of experience covering Kiribati. Diffey says the two biggest players in the region are Kiribati and Papua New Guinea.
Financial markets are tracking the development closely as investors assess the likely impact.
