  4. 3. Recent changes in land use and productivity in agro-pastoral Inner Mongolia, China

    Författare :Sara Brogaard; LUCSUS; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geomorphology; Physical geography; China; Inner Mongolia; remote sensing; LUE model; primary production; GPP; yield variability; land degradation; farmers’ perception; productivity; Land use; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : This study challenges the prevailing assumption that the expansion of cultivated land areas and increasing number of livestock in the agro-pastoral regions of northern China have aggravated the process of land degradation since the start of the rural reforms in 1978. Land-use and productivity trends in the Inner Mongolia Autonomous Region (IMAR), with special attention to the Keerqin steppe region, have been analysed. LÄS MER

  5. 4. Ecostrategies in theory and practice : Farmer's perspectives on water, nutrients and sustainability in low-resource agriculture in the dry zone of Sri Lanka

    Sammanfattning : PROBLEMThe need for a sustainable man - nature relationship has long been a neglected aspect of development theory. The increasing awareness of this negligence has led to a search for development strategies alternative to conventional industrial growth. LÄS MER

  7. 5. Integrating legumes in mixed crop-livestock systems in east Africa: Farmers' perceptions, ecosystem services and support for decision making

    Författare :Tarirai Muoni; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Challenges faced by smallholder farmers in east Africa include limited access to inputs, small farm sizes, and erratic rainfall patterns. Legume intensification and species diversification have been recommended for improving food and nutritional security, controlling soil erosion, improving soil fertility, supplying income and providing fuel.
