Breadfruit, the new, old wonder food, seen growing in Hawaii.
Everything old is new again. In today’s story, it’s breadfruit, an easy to grow food that’s been rediscovered as a tool in the fight against food insecurity.
Stephanie Hanes reports for the Christian Science Monitor, “When Diane Ragone travels around the Hawaiian Islands these days, it’s not hard for her to spot breadfruit. It is there in the farmers markets, knobby green fruit the size of a softball. It’s listed on menus as an ingredient in soufflés and nachos, flours and pastas. It is celebrated at festivals and studied by international scientists; it is served at food banks.
“It is also growing on trees.
“Some of these trees are in the National Tropical Botanical Garden, grown from specimens that Dr. Ragone has collected from across the Pacific, tended by the staff of the Breadfruit Institute, an organization she helped create 20 years ago. But there are other breadfruit trees she can spot across the islands, in hardscrabble neighborhoods and on millionaire’s lawns, in middle-class backyards and on university campuses.
“She can tell from their age and variety that many of these trees came from some of the 10,000 or so specimens that she and other groups have distributed across the state. But there is another, simple reason that she is seeing so much breadfruit: The plant, according to a number of researchers here, is becoming popular again, bringing with it a return to an old approach to island food security. …
“She says, ‘When I started working in the ’80s, there was some breadfruit here in Hawaii. … But overall, it was a really undergrown and underutilized plant.’
“The slow resurgence of breadfruit, a species that once served as a key food source across the Pacific but declined in use as local diets became more institutionalized, has big global implications, scientists say.
Last year, Northwestern University climate scientist Daniel Horton published a study showing that breadfruit, unlike other starchy staple crops, may be relatively unaffected by climate change.
” ‘This is particularly important for the tropics, he says, where communities are facing the interconnected challenges of climate change and food insecurity. …
“Although the breadfruit is not a great fit for industrial agriculture, with its short shelf life and delicate harvest time, it does provide local food resilience. Dr. Horton’s partner on the study, Northwestern University and Chicago Botanic Garden breadfruit expert Nyree Zerega, says that with one mature breadfruit tree, a family can harvest nutrient-dense food for generations.
“ ‘It’s a perennial crop, a tree, so you plant it and it lives for years,’ she says. ‘It doesn’t have as much of a carbon footprint [as other agricultural plants], and simultaneously it sequesters carbon. You can grow it mixed with other crops.’
“For people who live on islands, who tend to rely heavily on food imports, this is a big deal. Once a tree matures, it provides 200 to 300 pounds of food every year, says Kento Nemoto, marketing manager of the Hawai‘i ‘Ulu Cooperative, a farmers organization named for the Hawaiian term for breadfruit. ‘In terms of food security, it’s an amazing tree,’ he says. …
“In the library archives at the University of Hawaii in the early 1980s, Dr. Ragone, then a master’s student in horticulture, was charged with writing a paper on a tropical plant and had decided to focus on breadfruit in Tahiti.
“As she sifted through source material in the stacks, she kept coming across references to the plant in missionary accounts, agricultural reports, and more. …
“ ‘Traditional varieties and knowledge about breadfruit was at risk. I was fascinated by that – it just called to me.’ …
“It turned out that stem cuttings are unlikely to survive; to propagate breadfruit, one needs cuttings from the tree’s root system. It was the first of what would be many challenges of finding, collecting, and then growing breadfruit.
“During fieldwork on some 50 islands, she also recorded the ethnobotany of multiple communities. And then, in 2003 she helped found the Breadfruit Institute with the National Tropical Botanical Garden, and continued coordinating with colleagues throughout the tropics. …
“After challenges with other approaches to propagation, in 2009 Dr. Ragone, the Breadfruit Institute, and partners in Canada launched an initiative to grow trees from germ plasm, or plant genetic material. Today, that effort is largely being carried out by California-based Tissue-Grown Corp. Through a partnership with the nonprofit Trees That Feed and other organizations, it has over the past three years grown and then distributed thousands of trees genetically sourced from Dr. Ragone’s breadfruits, mostly in Central America, the Caribbean, and Africa.
“ ‘Oh my goodness, everyone is interested in it,’ says Karin Bolczyk, operations manager for Tissue-Grown. ‘And you feel like you are really making a difference. Every tree that gets into a backyard feeds a family for a century.’ “
