1. 11. Sustainable farming of Arctic charr (Salvelinus alpinus)

   Författare :Hanna Carlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Arctic charr (Salvelinus alpinus L.) is a salmonid that is well adapted to cold waters and is commonly farmed in open net cages. A breeding program has enabled a relatively large production in Sweden, providing a continuous supply of fresh fish to the market. LÄS MER

3. 12. Peasants and Stock Markets : Pathways from Collective Farming in the Post-Soviet Grain-Belt

   Författare :Brian Kuns; Anders Wästfelt; Mats Widgren; Jennifer Clapp; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agrarian change; environmental history; Ukraine; Russia; U.S.S.R.; large-scale agriculture; agroholdings; financialization; smallholders; peasants; irrigation; uneven development; actor network theory; multi-sited and mixed methods; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

   Sammanfattning : What happened in the post-Soviet, European grain-belt after collective farms were dissolved and in what way can we say that collective farm legacies influence agrarian developments in this region today? These are the main questions of this thesis, which is a work of critical human geography, but is also inspired by theories, methods and approaches from the social sciences, broadly defined. Territorially, the focus is Ukraine, but several articles in this thesis take a wider geographic perspective beyond Ukraine, in particular taking into account the role of Nordic investors in the agrarian sector in Ukraine and Russia.

4. 13. Advancing red clover breeding through genomic selection methods

   Författare :Johanna Osterman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Red clover is a major forage legume and a highly valuable crop for Northern Europe due to its high protein value and multiple ecological services. It is an important crop for both the ruminant industry and ecological farming. As growing conditions change due to rapid climate change, the demand for red clover breeding has increased. LÄS MER

5. 14. Temporal effects of organic farming on biodiversity and ecosystem services

   Författare :Dennis Jonason; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Agricultural intensification has caused a dramatic decline of global biodiversity and associated ecosystem services. Organic farming has been shown to partially counteract agricultural intensification by applying environmentally friendly and resource efficient farming practices, but opportunities to improve in efficiency still remain.

7. 15. Inferring Land Use from Remote Sensing Imagery : A context-based approach

   Författare :Michael Meinild Nielsen; Bo Malmberg; Anders Wästfelt; Douglas A. Stow; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land use; remote sensing; urban remote sensing; image analysis; segmentation; spatial context; land cover; land cover configuration; farming types; bark beetle; dead trees; forest inventory; kulturgeografi; Human Geography;

   Sammanfattning : This doctoral thesis investigates the potential of classification methods based on spatial context to infer specific forms of land use from remote sensing data. The problem is that some types of land use are characterized by a complex configuration of land covers that traditional per-pixel based methods have problems classifying due to spectral heterogeneity.
