Image and Reality at Sea
In this chapter, using the author own field data from Satawal island, the author examines navigational knowledge which has been considered non-effective for practical navigation. The author will then illustrates the importance of that knowledge in which fish and other sea creatures are employed as metaphorical tools to facilitate orientation and place-finding at sea. Finally, the author introduces an image-mapping theory as a new way of understan…
Comprehensive geriatric assessment for community‐dwelling elderly in Asia compared with those in Japan
Background: The objective of the present study is to compare the findings of comprehensive geriatric assessments (CGA) of community‐dwelling elderly people living in Lao People's Democratic Republic (Laos) with those in Japan. Methods: A cross‐sectional, interview‐ and examination‐based study was undertaken. The subjects consisted of community‐dwelling elderly people in Songkhon, a rural district in Laos and in Sonobe, a rural town in Kyoto, Japa…
Stable carbon and nitrogen isotopic composition of diet and hair of Gidra‐speaking Papuans
The carbon and nitrogen stable isotopic composition of the scalp hair and diet of Gidra-speaking people in four villages in Papua New Guinea is presented. The isotopic composition of hair was measured, while that of the diet was estimated from food consumption survey data and the measured isotopic composition and protein and carbohydrate contents of food items. The average isotopic ratios of the hair samples and of the diet varied among the four …

Introduction to the Proceedings of the Symposium, “Sustainable Development and Anthropology”
Global environmental problems such as global warming, tropical deforestation, and biodiversity have commanded a disproportionate share of public attention
Indigenous Resource Management and Sustainable Development
In tropical waters reefs provide local populations with food as well as with a source of income. Various types of regulatory measures have been adopted worldwide for the sustainable use of these resources. The cases of Papua New Guinea and Indonesia are examined to evaluate the roles of customary practices under rapidly changing socio-economic conditions. In Maluku, eastern Indonesia, harvesting of coconut, sago, trepang, trochus, and reef fish i…
Serum mineral and trace element concentrations in the Gidra of lowland Papua new Guinea
Serum concentrations of 11 elements (Na, Mg, P, S, K, Ca, Fe, Cu, Zn, Sr and Se) in the adult populations of the Gidra in lowland Papua New Guinea were measured. The marked characteristic of the element profile in the Gidra was higher Cu and slightly lower Zn concentrations than those in developed countries. Zinc nutriture of the Gidra was judged to be marginally deficient, presumably because of their high intake of crude fiber and Fe, which are …
Carbon and nitrogen isotopic characterization for Papua New Guinea foods
Stable carbon and nitrogen isotope ratios of the animal and plant food of the Gidra, who inhabit lowland Papua New Guinea and subsist mainly on hunting, gathering and horticulture, were measured to characterize the nutritional input of carbon and nitrogen of the Gidra. All the staple plant foods of the Gidra, such as sago and tuberous crops, were classified as C3 plants from their 13C/12C ratios (δ13C). The δ13C of the terrestrial mammals varied …
Dietary selenium intake of the Gidra, Papua New Guinea
Selenium (Se) concentrations in the food of the Gidra‐speaking people of Papua New Guinea were measured by fluorometry. Animal foods contained Se in larger concentrations than plant foods. Animal foods of aquatic origin contained more Se than those of terrestrial origin. Stepwise multiple regression analysis revealed an association between Se and the animal's mercury content. Se concentrations in rice and wheat flour, which were imported from out…
Hair element concentrations of the Gidra in lowland Papua
Concentrations of 11 elements (Na, Mg, Al, P, K, Ca, Mn, Fe, Cu, Zn, and Sr) were measured in 505 hair samples collected in 1981 from four (northern, inland, riverine, and coastal) villages of the Gidra who inhabit the lowland of Papua New Guinea. To compare the dietary element intakes with the hair element concentrations, the elimination of elements from hair by washing was first examined. Elimination rates by washing markedly differed from elem…
Compositional character of Papuan foods
In 78 food samples collected in the Papuan lowland, concentrations of major nutrients and trace elements (Na, Mg, A1, P, K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Cd, Hg, and Pb) were measured. Principal components analysis of local foods distinguished animal foods from plant foods: factor 1 had large positive loadings on protein, Na, P, Zn, and Hg contents and negative on carbohydrate content, and factor 2, positively on Mg, Ca, Mn, and Sr contents.…
Element intake of the Gidra in lowland Papua
Intake of 17 elements (Na, Mg, Al, P, K, Ca, V, Cr, Mn, Fe, Ni, Cu, Zn Sr, Cd, Hg and Pb) was estimated in four villages of the Gidra in lowland Papua New Guinea. Among these elements, inter‐village variation of intake was relatively large for Na, Al, V, Fe, Ni, Cd, Hg and Pb. The variation was attributed to the different concentrations in foods and drinking water, and the differences in food consumption by different villages. Compared to the int…
Salt consumption, body fatness and blood pressure of the Gidra in lowland Papua
The Gidra population in lowland Papua New Guinea, having lived as a no‐salt culture, is now subjected to modernization. In 1981, salt consumption, body fatness and blood pressures were measured for people in four ecologically different villages. Daily salt consumption of individuals was estimated from the sodium level per unit weight of creatinine in the morning urine and the daily urinary excretion of creatinine (estimation from fat free mass). …
Visual acuity of the Gidra in lowland Papua New Guinea
Visual acuity was tested and the anterior portion of the eye inspected among the Gidra in Lowland Papua New Guinea, who depend on hunting for their animal food. The visual acuity of the youths and adults was as high as that of hunters and gatherers; 88% of the males and 81% of the females had an acuity of 1·2 or better. The elders had far lower acuity, correlated with the advance of cataract (or corneal opacity). The senescent visual acuity is di…
Diversity and change of food consumption and nutrient intake among the Gidra in Lowland Papua
Food consumption and nutrient intake of the Gidra in lowland Papua, who number 1,850 and inhabit 13 villages, were analyzed by compilation of five two‐week (or twelve‐day) records, in a single village in 1971 and in four different villages (including the above village) in 1981. The nutrient intake of the Gidra varied both over time and among the villages. Difference in food consumption patterns included different proportions of plant staples such…
Composition of local and purchased foods consumed by the Gidra in Lowland Papua
Seventy‐eight foods (70 locally exploited and 8 purchased) consumed by the Gidra in lowland Papua were sampled and their nutrient compositions and metal concentrations were determined. Because local food samples were collected in the state in which they were normally eaten by the villagers, the water content of several of our samples, especially of sago flour, was much greater than that in the literature. The variation of protein and energy conte…
