  1. 6. Soil formation and soil moisture dynamics in agriculture fields in the Mekong Delta, Vietnam conceptual and numerical models

    Författare :Pham van Quang; Per-Erik Jansson; KTH; []
    Nyckelord :climate; CoupModel; pressure head; GLUE; soil water; characteristic curve; tensiometer;

    Sammanfattning : Previous studies of agricultural conditions in the Mekong Delta (MD) have identified soil compaction as an obstacle to sustainable production. A conceptual model for soil formation was presented to demonstrate the link between soil hydrology and plant response. LÄS MER

  3. 7. Wild vegetables and micronutrient nutrition : Studies on the significance of wild vegetables in women's diets in Vietnam

    Nyckelord :Medical sciences; Edible wild plants; gathered vegetables; Vietnam; micronutrients; rapid appraisal; dietary assessment; nutrition status; chemical analysis; food diversity; folate; medicinal foods; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Nutrition; näringslära;

    Sammanfattning : The principal aim has been to investigate the contemporary role and importance of edible wild plants in the diets of women in different agro-ecological regions of Vietnam. Field studies were undertaken in four villages in the Mekong Delta (MD) and the Central Highlands (CH) in 1995-1999. LÄS MER

  4. 8. Evaluation of locally available feed resources for striped catfish (Pangasianodon hypophthalmus)

    Författare :Chau Thi Da; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis investigated and compared inputs and outputs, economic factors and current feed use in small-scale farming systems producing striped catfish (Pangasianodon hypophthalmus) in the Mekong Delta. The nutrient content of locally available natural feed resources for striped catfish was determined and growth performance, feed utilisation and body indices were analysed in pond-cultured striped catfish fed diets where fish meal protein was replaced with protein from local feed resources.

  5. 9. Statistical aspects of modeling panel data originating from smallholder household surveys in Sub-Saharan Africa and Vietnam

    Författare :Sultana Nasrin; Statistiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power of test; endogeneity; multivariate; longitudinal data; diversification;

    Sammanfattning : This thesis focuses on multivariate multilevel modeling of panel data originated from smallholder farm surveys in Sub-Saharan African (SSA) countries and Vietnam to investigate driving forces in maize and rice production in SSA and diversification of farms in the rice sector in Vietnam. We also present and evaluate different tests for endogeneity in explanatory binary variables in multivariate linear regression models. LÄS MER

  7. 10. Prosocial Behavior, Social Interaction and Development: Experimental Evidence from Vietnam

    Författare :Nam Pham Khanh; Göteborgs universitet; []

    Sammanfattning : Paper 1. Funding a New Bridge in Rural Vietnam: A Field Experiment on Conditional Cooperation and Default Contributions The ability to provide public goods is essential for economic and social development, yet there is very limited empirical evidence regarding contributions to a real local public good in developing countries.
