90% Of PNG Island Population Has Left In 10 Yrs, Thanks In Large Part To Rising Seas
Most of the population on the remote atoll of Takuu, also known as Mortlock, in Papua New Guinea's Bougainville region are said to have resettled in Buka town.
From a population of at least 600 ten years ago, only around 50 people remain on Takuu, according to an indigenous Mortlock Islander.
Now based in PNG's capital Port Moresby, Raroteone Tefuarani says most young people have left the atoll.
She says due to the lack of education and health services, many people feel they must leave Takuu. But climate change is also a factor: Takuu, like other outliers in the region, has been steadily impacted by rising sea levels and declining food crops.
