Maria Popova linked to this story on twitter. It’s about how climate change is affecting a way of life for Fiji Islanders.

Meehan Crist writes at the blog Nautil.us, “The day that conservation biologist Joshua Drew, his two students, and I arrive in the Fijian village of Nagigi, the wind is blowing so hard that the coconut palms are bent sideways. ‘Trade winds,’ we are told. And, ‘El Nino. The villagers here also know that climate change is affecting the weather, but their more immediate problem, shared across the Pacific—and, indeed, the world—is an ocean ecosystem sorely depleted by overfishing.

“Nagigi is a village of about 240 people living in tin-roofed wooden homes strung along a sandy coastline. A single paved road runs the length of the village, parallel to the ocean, and along this road are homes clustered by family, painted in cheerful pastels, and connected by well-worn paths through the crab grass. ‘Before,’ said Avisake Nasi, a woman in her late 50s who has been fishing this reef her whole life, ‘you just go out and you find plenty fish. Now, you have to look.’ …

“If pressures mount from too many sides at once—rising ocean temperatures, acidification, pollution, overfishing—the combined pressure will be too much even for Fiji’s remarkably resilient reefs to bear. …

“Conservationists and humanitarian groups have recently united in the call for sustainable resource management, and in this trend, Nagigi is ahead of much of the Western world. Villagers have been discussing how they might use a traditional ban on fishing known as a tabu (tam-bu) to help manage their marine resources in new ways. …

“Drew presents his findings about how fish here are interconnected with other reefs, and how to best protect the species most important to the village in terms of food and income. He talks about how, for the last three years, he has been collecting baseline data about the species present on the reef so that if the village sets up a tabu, its effects can be measured.

“His audience is most interested in what Drew has to say about where to set up a tabu—include the mangroves at the left side of the village shore, because they act as fish nurseries—and for how long—three years would give crucial species enough time to mature and spawn. There has been some talk of a one-year tabu, which would be less of a hardship for villagers who will have to walk a mile or more to reach ocean where they are allowed to fish. But Drew’s data suggest this wouldn’t be long enough to make the sort of difference the village wants to see. ‘I can only offer information,’ Drew says at the end of his presentation, ‘the decision is yours.’ ”

The reporting for Crist’s  story was made possible by a grant from the Mindlin Foundation.

I was reminded of a recent science article this morning. Erik was speaking Swedish to my one-year-old grandson, and John said he shows the three-year-old foreign-language cartoons because it’s a great age to get an ear for them.

I recalled something interesting in the NY Times. Tim Requarth and Meehan Crist wrote, “Babies learn to speak months after they begin to understand language. As they are learning to talk, they babble …

“But when babies babble, what are they actually doing? And why does it take them so long to begin speaking?

“Insights into these mysteries of human language acquisition are now coming from a surprising source: songbirds.

“Researchers who focus on infant language and those who specialize in birdsong have teamed up in a new study suggesting that learning the transitions between syllables — from “da” to “do” and “do” to “da” — is the crucial bottleneck between babbling and speaking. …

“The lead author, Dina Lipkind, a psychology researcher at Hunter College in Manhattan [said], “What we’re showing is that babbling is not only to learn sounds, but also to learn transitions between sounds.” …

“At first, however, the scientists behind these findings weren’t studying human infants at all. They were studying birds.

“ ‘When I got into this, I never believed we were going to learn about human speech,’ said Ofer Tchernichovski, a birdsong researcher at Hunter and the senior author of the study, published [in] the journal Nature. …

“Dr. Tchernichovski and Gary Marcus, who studies infant language learning at New York University and who helped design the study, discussed the results. Could the difficulty learning transitions in songbirds hold true for human infants?

“By analyzing an existing data set of recordings of infant babbling, they found that as babies introduce a new syllable into their repertory, they first tend to repeat it (‘do-do-do’). Then, like the birds, they begin appending it to the beginning or end of syllable strings (‘do-da-da’ or ‘da-da-do’), eventually inserting it between other syllables (‘da-doda’).” More.
