    Notizen: Abstract Retrospective data collected in two urban neighborhoods of Tianjin, People's Republic of China, reveal a decline in the rate and duration of breastfeeding since the mid-1930's. There is no reason to suppose that this decline was stimulated by policies intended to discourage breastfeeding, or by pressures from commercial interests determined to expand the use of milk substitutes or supplements. The evidence indicates that breastfeeding declined as women became involved in work outside the home, as they adopted a form of postmarital residence that separated them from other relatives, as income increased, and as their rural origins decreased. No evidence was found to indicate a relationship between breastfeeding and parity or sex preferences.

    Notizen: Abstract The energy flows in a seventeenth century agroecosystem in Jiaxing region of eastern China were analyzed on the basis of historical data. The agroecosystem included cropping, mulberry-silkworm, livestock, and fishing systems. In terms of energy, the agroecosystem was sustainable. Human labor provided all the power with inputs of about 3700 hr per hectare of farmland. Most or 70% of the labor was expended in the cropping system. Human and animal manure provided most of the nutrients for crop and mulberry production. About two-thirds of the total manure was used in crop production and one-third in the mulberry plantations. The only fossil energy input was a few hand tools. Approximately 55% of the grain was consumed directly by local residents, about one-third of the grain was used to make an alcohol drink and produce distillers'grains, which was fed to pigs, and only 2% of the grains were exported outside the agroecosystem. About two-thirds of the harvested crop residues were used as household fuel, while the remainder was returned to the field as an organic fertilizer. Pork accounted for 85% and silk cocoons 14% of the total animal products produced. Even though the agroecosystem was generally sustainable in terms of energy, the major environmental problem was that two-thirds of the harvested crop residues were used for household fuel. This reduced nutrient cycling in the system. Insufficient land was available to produce fuelwood;thus, crop residues were the primary source of fuel for the people.

    Notizen: Abstract The Pearl River Delta offers humans a variety of land-use alternatives. A complex ecosystem which has been in existence in the Delta for centuries has greatly contributed to the region's agricultural productivity. The principal components are mulberry trees, silkworms, pond fish, and humans, interrelated in a harmonious and mutually beneficial way. The system is not only highly efficient and soundly balanced ecologically, but provides much higher economic returns than do other agrarian practices in the Delta.

    Notizen: Abstract In the last few years, considerable evidence has been obtained regarding the importance of zinc in human nutrition. Zinc is an important component of many metalloenzymes and is also required for metabolism of nucleic acids and synthesis of protein. Human requirements for zinc vary at different times in development, but appear to be particularly high during embryonic life, during periods of rapid growth, and during pregnancy. Although zinc is widely distributed in foods, a number of types of diets appear to be deficient or marginal in terms of available zinc. In addition, there is physiological loss of zinc in bleeding and sweating which may lead to low levels of body zinc. A syndrome characterized by markedly retarded growth and sexual development that occurs in the Middle East has been shown to be due to zinc deficiency. This syndrome is reviewed. It is thought that the zinc deficiency syndrome is only one end of a continuum of growth-related problems associated with low levels of physiologically available zinc. In rats, zinc deficiency during pregnancy has been shown to lead to congenital malformations in a large percentage of the offspring. A number of these malformations involve the central nervous system. We have suggested that epidemiological data support the possible importance of maternal zinc deficiency as an etiological factor in human CNS malformations. These data are discussed.

    Thema: Biologie , Energietechnik , Ethnologie
    Notizen: Abstract This paper explores the changing political ecology of soil and water management—the articulation of physical and political-economic processes—in the Loess Plateau of north-central China. Market-oriented reforms and the shift from collective to household farming have created a diverse array of tenure, management, and financing arrangements. In the process relationships between farm households, the collective, and the state have been altered, with profound implications for land use and sustainability. The paper reviews the political ecology approach and its relevance to environmental management in China. An outline of the physical and economic context of soil erosion in the Loess Plateau is followed by examination of the impact of reform on rural environmental management. Local innovations in the organization of environmental management are highlighted. The conclusion comments on the utility of the regional political ecology approach and suggests some critical issues for further research.

    Notizen: Abstract This research was designed to test the following hypothesis: Among traditional (nonliterate and minimally literate) people residing in their home environment, traditionally derived knowledge of specific cases of ecological processes can approximate scientifically derived knowledge of those same cases. After locating three minimally literate peasant family lineages in Lijiayang and Linfengkeng villages, Shouning County, Fujian Province, China, not applying science-based systems of agroforest management, a decision-tree model of an indigenous agroforest management system was constructed from extensive interviews. The system was centered around shamu (Cunninghamia lanceolata),an important timber species with a long history of management in China. A major part of the management system is agricultural intercropping with a wide variety of cereal, cash, medicinal, and oil-producing crops. Intercropping is practiced in the initial phases of afforestation; is an integral aspect of site preparation and the tending of the young stand; and contributes to tree establishment, growth, and survival. The cases presented demonstrate that local peasant knowledge of the effects of burning, site preparation, crop selection, crop tending, and intercropping duration on soil quality and the survival and development of shamu is strongly analogous to the knowledge derived through systematic scientific research. This process of deriving scientifically valid ecological knowledge through traditional means is called protoscience.

    Notizen: Abstract A quantitative analysis of major rural energy flows in the People's Republic of China shows that the nation 's countryside still depends predominantly on solar radiation transformed by green plants through photosynthesis into food, feed, fuel, and raw materials. Although a large-scale modernization effort currently under way aims to greatly increase the consumption of fossil fuels and electricity, it is argued that the country should not completely abandon its renewable rural energetics.

    Notizen: Abstract Data from two rural Chinese settings suggest that an ecological variable — the reliability of food supply — may exert a more decisive influence on birth seasonality than time of marriage or attributes of temperature, rainfall, or workload. First births seem to be especially important for patterns of seasonality; comparison between villages suggests that a periodic but reliable source of food may encourage a seasonal distribution of first births, the effect of which might be to protect the mother and/or her newborn infant. It is the periodicity of first births that may give aggregate birth figures the appearance of seasonality.

    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Energietechnik , Ethnologie
    Notizen: Abstract Taungya is a system of forest management in which land is cleared and planted initially to food crops. Seedlings of desirable tree species are then planted on the same plot, leading in time to a harvestable stand of timber. Taungya is believed to have been developed by the British in Burma during the nineteenth century. Historical research indicates that successional systems of forest management which follow the pattern of taungya have been used for at least three centuries by ethnic minorities in and by the Han population. The resilience of these systems is associated with economic and social factors which have made the cultivation of trees an adaptive strategy of land use for the inhabitants of the highlands of southern China.

    Notizen: Abstract Scholars have rarely reflected upon dune sand in any context other than that of environmental hazard. Yet recent anthropological research conducted among ethnic Mongol herders in the Keerqin Sandy Lands of Northeast China indicates that native inhabitants exhibit a surprising degree of tolerance, appreciation, and even preference for dune sand at specific spatio-temporal scales. Survey data, gathered primarily through the use of photographic prompts and pile sort exercises during household interviews, reveal that many residents even regard dune sand as the constituent element of a distinctive home environment and cherished way of life. This research underscores the relevance of perception to the policies and practices of human resource management. It also calls into question the authority with which officials and scholars in China and elsewhere indiscriminantly depreciate the various social utilities of dune sand in stock-herding populations.
