Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge.

Coconut palm is a multipurpose crop cultivated in tropics. Diversity in this crop is rich in South Pacific Ocean and Indian Ocean Islands. Foliar traits have not been studied extensively to understand the diversity. Seven traits relevant to wind tolerance, dry matter production and taxonomic discrimination known in palms are used in the study. An attempt was made using Shannon–Weaver index with an objective to understand the level of diversity for these traits in a germplasm collection from diversity hotspot areas. Seven tall groups and four dwarf groups representing seven island territories were studied using 206 individuals. Diversity estimate was the highest in Nicobar tall group whereas it was low in tall genotypes of Fiji and Tonga. Thickness of leaf sheath fiber of weft and warp strands had shown high diversity estimates. Results obtained in this study were analyzed in relation to adaptation, geographical affinity, mating system and taxonomic forms (typica and nana) along with the importance of foliar traits in diversity of coconut.

Rainforest conservation for emissions
Friday, at the United Nations Framework Convention on Climate Change in Montreal, the U.N. agreed to a "rainforest conservation for emissions" proposal that allows developing nations to receive financial compensation from industrialized countries for agreeing to preserve their rainforests. Environmentalists hope the deal -- set forth by ten developing countries led by Papua New Guinea -- will give developing nations a financial reason to get more involved in climate talks while safeguarding globally important ecosystems.

Nauru Keen To Relearn Food Gardening
Pacific Magazine, Tuesday: December 6, 2005
The Food and Agriculture Organisation says it is getting a very good response as it encourages Nauruans to start growing their own food.
Agriculture on the island has been largely ignored over the past two generations with the people relying on imported food.
With the collapse of the economy that is no longer possible, and food security, through the fostering of local agriculture, was part of a sustainable development strategy presented to aid donors last week.
Manase Felemi, of the FAO, says the organisation’s been developing gardening skills with an emphasis on community plots, and this has been widely appreciated on the island.
“What we have found is that a lot of the people who come to the group training at the community level - not only have they participated in the preparation of the community plot, but they have gone back home and started preparing their own plots - making preparations to plant their own small gardens in the backyard, which is a very positive development in this project and it’s a very encouraging sign.”
Reported By RNZI
I was just in Nauru - and was rather disappointed to find out that many of the people who have expressed interest in growing foods have picked non-indigenous and quite high-maintenance crops such as lettuce and cucumber - and also fairly low nutrient density.
Not a comment on Nauru, but could not find any other way of sending it!Post a Comment

Mangosteen making an impact in US
12/21/2005 - Mangosteen, a little-known fruit from southeast Asia, ranks amongst the antioxidant-rich ‘superfruits’ that have attracted increasing interest from industry and consumers this year, and awareness looks set to grow in the coming year.
The fruit, which originates from southeast Asia, is still relatively unknown in the United States.
Some studies have investigated the role of mangostin, one of a family of active compounds known as xanthones, in inhibiting the oxidation of LDL-cholesterol and the activity of PGE2, COX-1, and COX-2 (prostaglandin E2 and cyclooxygenases-1 and -2) – key factors involved in inflammatory conditions.
Datamonitor's ProductScan Online identified mangosteen as one of several antioxidant-rich fruits that, together, make up one of its top ten trends to watch in 2006.
Director Tom Vierhile told NutraIngredients-USA.com that three food and beverage products were identified by the market researcher in 2005, compared to two in 2004 and one in 2003.
Whilst this indicates a trickle rather than a flood, he said that there is “some interest in the benefits of superfruits like mangosteen and pomegranate, so we are seeing companies turn these into headline products”.

Islanders fight to save vesi trees
Fiji Times, Friday, December 09, 2005
A HISTORIC conservation program to save a native species of trees on the verge of extinction is being undertaken by a community that has largely exploited it for commercial reasons.
Kabara islanders in the Lau Group are actively involved in the historic reforestation program geared at saving the vesi trees, or Intsia bijuga as it is scientifically known.
The effort, under the guidance of the World Wide Fund for Nature and the Government, has led to the first nursery of vesi trees being set up on the island.
"We are initiating the reforestation program to ensure the community takes an active approach towards sustainability," said WWF's sustainable forest project officer, Francis Areki.
The trees are a source of high value timber. Of Kabara's remaining forests, only eight per cent are vesi trees.
The majority of the 400 or so Kabara islanders are reliant on the vesi timber for their carvings which they use to generate income. "There is a lack of replanting of vesi in Fiji," said the Ministry of Forestry's Acting Principle Forestry Officer, Temo Raravula.
"We are raising the seedlings of native trees but now we have difficulty in finding seed sources. From my observation in the forest here, there is hardly any re-germinating as expected. Not many trees are bearing seeds," he said.
"There is no other way that there will be a sustainable supply of vesi in Kabara unless we do this replanting program.
"The villagers have to now plant where they have already logged. Together with replanting, the use of timber has to be improved."
Furthermore, villagers have been taught a new skill in carving so that they can use the off-cuts and other wood resources other than the vesi.
For the last three months, five of the villagers have been undergoing training in Nasinu and will return to the island in February to impart their knowledge.
We have recently started to use a simple but very effective propagator for multiplication of indigenous nut and fruit trees. I will see if we have Intsia here in East New Britain and, if so, ask our scientists to try to propagate it from cuttings. If it works we can then liase further to help Kabara.Post a Comment

Food Survey in Pohnpei
From Lois Englberger: I would like to give you a preview of an article coming out today in the Kaselehlie Press. This was written by Amy Levendusky. The findings are the result of painstaking work in making quantified estimates of dietary intake, using one of the most widely used dietary assessment methods, the quantified 24-hour recall. To see the article in print with the accompanying photos, turn to the KP Health Corner! For those readers not familiar with Pohnpei, the site of this study (Mand) is a rural village about 1 hour from the main town of the island.
Survey Indicates High Consumption of Imported Foods
by Amy Levendusky
A dietary assessment carried out in August 2005, in Mand, Madolenihmw [a village on Pohnpei Island] revealed that only 27% of the energy consumed by the adult female participants was from local food, the rest provided by imports. Among children an even smaller proportion of the energy consumed was from local foods (16%).
These results are from a random sample survey, conducted as part of the project entitled "Documentation of the Traditional Food System of Pohnpei" sponsored by the Island Food Community of Pohnpei. Yumiko Paul, of Pohnpei Department of Health, Welsey Hagilmai, of COM/FSM Land Grant, and Pelihna Moses of Mand Community served as the interviewers, assisted by Douglas Nelber, Department of Land and Natural Resources. In collecting the data,
a 24-hour recall method was used (asking adult participants to recall each food/drink item consumed in the past 24 hours and the amount, and to provide this information as proxies for their children). Data from 44 adult women and 27 children (aged 1-10 years) were obtained for two non-consecutive days.
The survey revealed that rice and fish were the two food items most frequently consumed by the women, followed by flour products (donuts, pancakes, bread and ramen), chicken and other meats, and banana and breadfruit (this was in the heart of the breadfruit season). Vegetables and fruits were not commonly consumed.
The survey also revealed that 62% of the protein consumed by the women was from imported sources. The levels of protein were sufficient but were far over the estimated requirements. The mean intake of protein for non-lactating (not breastfeeding) females was 109 grams per day, but the estimated requirement is only 45 grams.
On the other hand, vitamin intakes were very low. This puts the women and children at risk to infection and other health problems. The mean intake for the non-lactating female adults was 225 Retinol Equivalents (RE) (vitamin A is expressed by the combination of retinol from animal sources and provitamin A carotenoid from plant sources), but the estimated requirement for that group is 500 RE! Almost none of the children met the estimated requirements. Also very few of the children met estimated requirements for vitamin C. Only 63% of the non-lactating females met the estimated vitamin C requirements, the lactating adults doing better, 83% of them meeting the estimated requirements.
IFCP would like to thank the Mand community for making this project possible. We would also like to thank our collaborating partners including the Pohnpei Office of Economic Affairs, COM/FSM Land Grant, Department of Health, Department of Land and Natural Resources. Thanks are also extended to the Office of Economic Affairs and the Secretary of the Pacific Community (SPC) Pacific German Regional Forestry Project (PGRFP) for providing transport to the village and to the Centre of Indigenous Peoples’ Nutrition and Environment (CINE), PGRFP, and Sight and Life for support funds and materials.

Did Easter Island get 'ratted' out?
By Dan Vergano, USA TODAY
Rats and Europeans are likely to blame for the mysterious demise of Easter Island, a team of anthropologists suggests.
The fate of the people who built hundreds of 10-ton stone statues on the South Pacific island and then vanished has long been seen as a cautionary environmental tale. Natives deforested the island paradise to transport the statues, the story goes, triggering erosion that damaged farmlands. And then they supposedly bumped themselves off in a cannibalistic civil war in about 1650.
But anthropologist Terry Hunt of the University of Hawaii at Manoa first blames the Polynesian rat. The rats probably deforested the 66-square-mile island's 16 million palm trees. "Palm tree seeds are filet mignon to rats," Hunt says.
Working with colleagues at the island's anthropology museum and elsewhere since 2001, Hunt's team has undertaken an extensive archaeological survey of the island:
Instead, the disappearance of Easter Islanders probably was caused by visiting Dutch traders in the 1700s, who brought diseases and, later, slave raiding, says Hunt, who presented his findings at an American Anthropological Association meeting last week.

Bioprospecting in the Pacific: Who gets to benefit?
By Bill Aalbersberg, in Island Business. Professor Bill Aalbersberg is Director of USP's Institute of Applied Sciences. IAS aims to help Pacific Islands countries conserve and develop their resources sustainably (http://www.usp.ac.fj/ias/).
In the Verata district of Fiji, people turn to their Community Trust Fund for scholarship support for local students. In Faleaupo, Samoa, the cost of construction of a primary school was donated by a foundation in return for the community's conservation of their rainforest. Both the trust fund and the school's construction were made possible by bioprospecting.
Bioprospecting is the collection of plants and/or marine organisms by scientists looking for medicines that could be derived from the chemicals in the collected material.
Plants that have been used for traditional medicines, in many cases for thousands of years, are targeted. Evidence has shown that scientists have more than 10 times the chance of finding an active chemical in a medicinal plant than in a randomly collected one.
Besides medicinal plants, particularly valued are marine invertebrates such as sponges, soft corals and sea squirts, which are soft and colourful and move slowly, if at all (thus making them easy to collect), and tend to use strong chemical defences to prevent predation.
Time, money and expertise
A large number of medicines we buy at the pharmacy were discovered through bioprospecting. For example, the chemicals vinblastin and vincristine, now used in anti-leukemia drugs, were discovered in the ornamental rosy periwinkle (Catharanthus roseus). It is estimated that about one-third of the drugs prescribed in the United States-including aspirin, ephedrine, belladonna, penicillin, quinine, morphine, digitalis and many anti-cancer drugs-contain plant-derived components.
The process of drug discovery takes about 15 years from sample collection to having a marketable drug, and involves:
Who gets the benefits?
A major issue related to the work of bioprospecting is who benefits if medicines are found. In the past, plants and marine organisms were often collected from developing countries by Western researchers and the source country received little in return.
This neo-colonial “open access” policy was turned on its head by the 1993 Convention on Biological Diversity, which gave sovereign rights of biodiversity to the source country but encouraged them to allow access to outside researchers under mutually agreed terms.
Pacific countries have been slow to develop this so-called “access and benefit-sharing” legislation.
In the examples cited at the start of this article, it was the collecting group working with the local community who ensured that a wide range of benefits were made available to the source area. Responsible scientists understand the importance of preserving the biological diversity from which the chemicals come, and to further this preservation, they seek partnerships that will allow source communities to undertake conservation efforts.
Local organisms show promise
No chemical derived from a Pacific organism has yet been fully developed into a marketable drug. But several are showing promise.
The Universities of the South Pacific (USP) and Papua New Guinea (UPNG) are playing leading roles in the development of biodiversity by the use of biotechnology, having set up local enterprises to increase local ability to perform the work.
Both universities have received a prestigious International Cooperation in Biodiversity Grant given by the United States government to partnerships of US and overseas universities working to discover drugs and conserve biodiversity.
USP is working with the Georgia Institute of Technology and UPNG with the University of Utah, with funding of about US$3 million over a five-year period. USP's Institute of Applied Sciences (IAS) has set up a research unit in collaboration with the Regional Germplasm Centre of the Secretariat of the Pacific Community (SPC), focusing on marine biotechnology such as DNA fingerprinting of sponges and soft corals.
Collaborations such as these are helping to bring benefits to the people of the Pacific and, ultimately, to the people of the world.

Cassava for ethanol
Island Business reports that a Korean company has leased 3248 hectares of customary land in Papua New Guinea for a US$27-million investment in cassava growing for ethanol production. They don't say which varieties will be grown, but the NARI national cassava germplasm collection at Laloki numbers almost 80 accessions so there should be plenty to choose from.

Paying for forest conservation
If a coalition of developing countries has its way, there could soon be new forests sprouting up in tropical regions. The group of ten countries, led by Papua New Guinea, has proposed that wealthy countries pay them to preserve their rainforests. Since forests absorb atmospheric carbon as they grow and release carbon as they are cut or degraded, the coalition seeks compensation for the amount of carbon locked up by their forests. Focusing specifically on the value of carbon sequestration the coalition could be talking a lot of money. At the current going rate of $20 for a one-ton unit of carbon dioxide, the forests of Bolivia, Central African Republic, Chile, Congo, Costa Rica, Democratic Republic of Congo, the Dominican Republic, Guatemala, Nicaragua, and Papua New Guinea are worth around $1.1 trillion for their carbon sequestration alone. Of course the forests offer a great deal more value through the other, less measurable services they provide including fisheries protection, biodiversity preservation, erosion and flood control, recreation and tourism value, harvest of renewable products, and water services.

Australia to ratify International Treaty on PGR for Food and Agriculture
Press Release: Wednesday, 23 November 2005, 6:27 pm.
Australia will ratify a treaty covering the conservation, sustainable use and international exchange of plant genetic resources for food and agriculture.
Agriculture, Fisheries and Forestry Minister Peter McGauran made the announcement last night while addressing the 33rd Session of the United Nations Food and Agriculture Organisation (FAO) Conference in Rome.
"The International Treaty on Plant Genetic Resources for Food and Agriculture has important implications for the future productivity and international competitiveness of Australia's agriculture sector," he said.
"Our plant breeders rely heavily on genetic material from overseas to develop new crops - including new grains, oilseed, pastoral and horticulture varieties.
"The treaty sets out the legal framework covering access to this material and the sharing of the potential benefits. That provides our breeders with the certainty and confidence they need to access the genetic material needed to keep Australian agriculture at the international forefront."
Mr McGauran said Australia would continue to work closely with FAO on the detail of the treaty's working provisions.
"Final decisions in this regard are expected to be made at the first meeting of the treaty's Governing Body in Spain next June," he said.
"Australia will also remain a major donor to the Global Crop Diversity Trust - a key source of funding for the treaty. The Trust promotes long-term food security by coordinating international, regional and national crop collections around the world."
Mr McGauran said Australia holds significant collections of genetic plant material in seed banks around the country.
"To ensure this material is properly managed and conserved, we will set up the National Genetic Resource Centre," he said.
"It will have the job of coordinating Australian-based collections, as well as improving their content and long-term efficiency. The Centre will also be responsible for ensuring that any obligations arising from the treaty are met by the Australian collections."

Two Pacific Coconut Success Stories
From Pacific Magazine.
Coconut Crazy Vanuatu Firm Revolutionizes Copra Processing
By Tiffany Carroll
A South African family is vowing to turn Vanuatu's coconut industry around with a revolutionary oil-extracting machine that would see the end of copra cutters in the archipelago.
Mark Bowker of Vanuatu Virgin Coconut Oil (VVCO) says the machine, designed by his grandfather, will be able to extract five tons of virgin coconut oil a day, something that would normally take at least six days. He says it will also result in consistently higher quality oil.
"Current copra drying methods are neither hygienic nor quality controlled, meaning the buyer cannot be assured of the grade of oil every time," he says.
The Bowker oil extraction process is totally mechanized and self-sufficient. The stainless steel machine is capable of processing large quantities of coconuts mechanically, as opposed to the current practice of cutting and digging out the meat by hand.
Virgin coconut oil is a lucrative commodity, with a market value hovering between $US8,500 and $US16,000 a ton. VVCO is offering six vatu per whole nut to coconut producers, averaging 30,000 vatu (US$268) per ton.
"That's way above market price and involves very little work for the farmer," Bowker says.
VVCO's product is destined for the health, beauty and pharmaceutical markets. The oil is extracted within one hour of the fresh nut being cut, eliminating the risk of bacteria developing during the handling process and reducing the quality of the oil. Whilst there are several virgin coconut oil businesses around the Pacific, most are producing less than 100 liters of oil a day.
"The process by which VVCO produces virgin coconut oil is not done anywhere else in the world and the fact the technology is patented worldwide means this will be good for Vanuatu as nobody can copy or replicate this process globally," Bowker says.
Bowker says Vanuatu's coconut industry is in urgent need of help and VVCO is committed to opening new export markets. "The (Vanuatu) farmer is already questioning his future in cutting and providing copra due to the high running costs. Some farmers are already changing their focus and looking for other options opposed to replanting a new generation of coconut trees."
Bowker is confident of producing an initial 2.5 tons of oil every eight hours. Vanuatu Virgin Coconut Oil eventually hopes to rely on just a few major plantation owners to supply coconuts. A large percentage of outer islanders are employed as copra cutters in Vanuatu. Many work for the larger plantations that VVCO is hoping will become suppliers of nuts.
If the Bowker process is successful, those workers could be out of jobs since there would be no need to crack the nuts and strip out the meat. However, the Vanuatu Investment Promotion Authority, the government body that approves all foreign investment in the country, is behind the Bowker's $A1.3 million (US$987,285) venture, giving approval for the business to operate and assisting with import tax breaks for the company.
"I hope farmers will see the future the way we do, and we'll all do well," Bowker says.
Fill It Up With Coconut Oil? Marshalls Firm Substitutes Coconut Oil For Diesel
By Giff Johnson
Most Pacific Islanders live on islands whose most noticeable product is coconuts, but there has been only sporadic interest in or energy spent on developing coconut fuel as a viable alternative.
In the Marshall Islands the situation has changed dramatically since late last year. Following experiments over the last three years with Tobolar Copra Processing Plant vehicles using coconut oil as a substitute for diesel fuel, Pacific International Inc.-the country's largest construction firm-is fueling its fleet of heavy equipment and its ocean-going vessels with cheaper and cleaner coconut oil.
"The questions, 'can you use coconut oil as a substitute for diesel' and 'what will it do to the engine?' were not easily answered," says PII owner Jerry Kramer about efforts to begin using coconut oil fuel in the 1990s.University of Hawaii studies indicated that use of coconut oil in diesel engines would deteriorate rubber hoses, clog filters, reduce the power of the engine and lead to excessive carbon build up, Kramer adds. The main drawback to using coconut oil is that the oil absorbs and holds moisture, and at temperatures below 78 degrees Fahrenheit, it hardens. But in the Marshall Islands it never gets below 78 degrees, so the only question that needed answering was about moisture and residue left in engines.
Kramer, whose company manages the copra processing plant for the government, simply started operating a vehicle on coconut fuel and after three years, "we opened up the engine and it was perfect," he says. "There was no carbon build up, the fuel lines were clear and the tank was clean."
For the past year, PII has been fueling all its diesel vehicles and ships with coconut oil. "Two of our loaders use coconut oil," he said. "There's no problems, no black smoke. It burns clean and smells sweet."
PII's two tugboats and the Deborah K cargo vessel are all running on coconut oil fuel. Now a number of other local vehicles are doing the coconut oil routine. The copra processing plant sells coconut oil at about $2 a gallon-a far cry from the $3.70 a gallon diesel customers were paying in early October.
The simplicity of the way unrefined coconut oil works in diesel engines immediately suggested to Kramer the opportunity for its use on remote outer islands in the Marshalls. He sees two good options: one is a five-kilowatt home unit diesel generator; another is for a larger 30 KW generator that powers a unit that produces coconut oil while providing additional electricity for community use.
He's developing this as a pilot plant for outer islands to produce coconut oil to fuel home-sized generators. A five KW generator run from coconut oil can support appliances such as a rice cooker, washing machine and TV-compared to most of the donated solar units going into outer islands that are big enough to power only one or two light bulbs.

"Identity and Development presents a remarkable record of Tonga's increasing participation in the modern global economy, and provides anthropologists, economists, and historians with a detailed case study that bears heavily on major issues of the day, both practically and theoretically. The book focuses on issues of identity, entrepreneurship, and the intricacies of development and addresses the question, 'How (in the current state of the economy) can a Tongan become a successful grower?' This question is set against the background of a boom in cash cropping, sparked by a burgeoning export trade with Japan. Identity and development is in the tradition of the best Pacific ethnographies insofar as it describes living individuals - their specific desires and aspirations, the dilemmas they confront, thecultural ambiguities they must contend with, the constraints andincentives that guide their activities. Van der Grijp explicitly rejectsthe 'love of ease which wanders through [...] postmodern anthropology' and commits to a comparative perspective that presupposes a dialectic between generalities and particularities, between abstract theory on theone hand, and case studies on the other. The book is a fine example of what this entails."

Pacifika improved and integrated farming systems
Income generation and a better environment from enriched and stabilised mixed crop farming
A Policy Briefing for Governments and Development Agencies in the Pacific Region: An output from a regional agroforestry workshop on ensuring food security and better livelihoods for Pacific people
The Problem - Because of increasing pressures for land in most Pacific island countries, shifting agriculture is no longer a sustainable form of land use. The needs of farmers have changed and shifting cultivation no longer meets the needs of farmers for food security and income generation. Most importantly, the shortened fallow periods no longer restore soil fertility and shifting agriculture is now damaging the environment.
The Facts - Traditional mixed cropping systems have many advantages. The benefits include:

Abstract: Direct accelerator mass spectrometry (AMS) dating of anaerobically preserved plant remains from the Dongan site in New Guinea, combined with assessment of preservation condition, confirms earlier doubts about the antiquity of betelnut (Areca catechu L.) found at the site. A possible sago leaf fragment is also identified as a modern contaminant. The mid-Holocene age of other fruit and nut remains is verified using these methods. The utility of AMS dating in combination with detailed archaeobotanical assessment is demonstrated, thus improving chronometric hygiene and with it knowledge of past plant use in Oceania.

Local foods and health
From the K-P Perspective column in the newspaper Kaselehlie Press, November 24-December 7, 2005.
IFCP-A Group Dedicated to your Health
The K-P Perspective has previously noted that the cures for many of the FSM's health problems are literally hanging on the trees or hiding in the dirt. Now an organization has been formed that will do more to assist you to get the right kinds of foods to eat. The Island Food Community of Pohnpei (IFCP) is a group of people who understand the importance of local food in the diets of all Micronesians. These folks have been arranging community meetings, producing videos, holding workshops, organizing food fairs, and now are working towards the on-island processing of local foods to make it easier to find good, wholesome, agricultural products at the markets. It is anticipated that these foods will find their way onto the dinner tables in many, many Pohnpeian homes. From the table, it is only a short trip by spoon or fork to where these foods can do their best work - in your body.
Prior to the arrival of imported and packaged food into Micronesia, there were few nutrition-related diseases in the island populations. Visit a museum or the Micronesian Seminar and look at some old photographs, you won't find very many fat or obese individuals. The imported foods have dealt a double curse.
First they made it physically easy to get food - no more sweating while working on the farm, or in the taro patch, or paddling canoes, or diving to catch fish. The opportunity for 'productive exercise' has been eliminated. And now with outboards, and cars, and jobs that only require sitting and talking (maybe a little typing), physical activity (that's when you sweat or breath hard) is something that you never have to do.
Second, the nutritional value of many of the imported foods is extremely low, and in several cases it is actually BAD for people to eat the stuff. (Ramen mixed with kool-aid!!!) Imported food is often expensive, and thus for people with limited funds, the imported food that they can afford is cheap and has little nutritional value. Why are turkey tails, and ramen and rice so popular these days? Because there has now been three or four generations brought up on these items, and what is fed to children on a regular basis, they usually grow to like.
So our KP-Perspective hats are off to the IFCP. Keep up the good work! Push for the public to start to eat the things that their grand and great-grandparents ate: breadfruit, yams, taro, bananas (including Karat - the best banana in the world, and the Official Banana of Pohnpei State) and all the rest.

Festive Micronesian Foods
From Dr Lois Englberger. You can subscribe to Local Food Trends, the Island Food Community of Pohnpei newsletter, edited by Amy Levendusky, by contacting Lois on firstname.lastname@example.org.
It is exciting to share with you that Jane Elymore, FSM Women's Coordinator, and previous FSM National Nutritionist, was recorded by Radio Australia on November 30, 2005, for a program talking about special festive Microneisan foods. This was on the "In the Loop" program, organized by Heather Jarvis and her colleague Isabelle Genoux, and is for the entire Pacific region. Heather had contacted me previously about their program and had made a short program about Pohnpei bananas, in particular about the promotion of the Taiwang variety. Then just recently she wrote that in the lead-up to Christmas they were putting some segments together from around the Pacific region about how Christmas is celebrated and asked if I could recommend someone to speak with them for a 10-15 minute chat on their program. I recommended Jane as I know that she has so much experience talking about food and nutrition and also because she likes cooking! Jane agreed and later told me how she had shared the recipe of Fafa Sukla, which is a special delicacy of Kosrae. It is exciting that special FSM recipes are being shared around the Pacific region!Thank you Jane for your willingness to talk, and thank you Heather very much for contacting us here in Micronesia!!
