3. 2. Archaeological and Historical Reconstructions of the Foraging and Farming Communities of the Lower Zambezi : From the mid Holocene to the second Millennium AD

   Författare :Hilário Madiquida; Paul Sinclair; Karl-Johan Lindholm; Dr Munyaradzi Manyanga; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Mozambique; Zambezi Valley; Late Stone Age; Early Farming Communities; Long-distance trade; Afro-Portuguese; Written sources; Archaeology; Historical Ecology; Archaeology; Arkeologi;

   Sammanfattning : In this thesis I combine new archaeological surveys and excavations together with the historical and ethnographic sources, to construct a long term settlement history and historical ecology of the lower Zambezi River valley and delta region, in Mozambique. The evidence presented indicates that people have settled in the area since the Late Stone Age, in total eight new archaeological sites have been located in archaeological surveys. LÄS MER

4. 3. Minerals and Managers: : production contexts as evidence for social organization in Zimbabwean prehistory

   Nyckelord :Archaeology; Zimbabwean past; farming communities; environment; mineral resources; mineral production; social organization; social change; Arkeologi;

   Sammanfattning : In the Zimbabwean past, farming societies utilized mineral resources for their own use and for exchange to local and regional populations, as well as to markets beyond African borders. Successful agriculture was constrained by environmental hazards, principally unpredictable and often inadequate rainfall. LÄS MER

5. 4. Resource management in traditional farming : A case study in the dry zone of Sri Lanka

   Författare :Erika Daléus; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : The potential of the traditional small irrigation systems in Sri Lanka has to a great extent been overlooked in the efforts to satisfy increasing food requirements and to bring about social development in rural communities. The aim of this study was to arrive at an improved understanding of the resource management ofthe traditional farming system in the Dry Zone of Sri Lanka. LÄS MER

7. 5. Diversity of soil microbial communities: In the perspective of targeting functional genes

   Författare :Lokeshwaran Manoharan; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

   Sammanfattning : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. LÄS MER
