  1. 1. Anthropogenic Open Land in Boreal Landscapes : Investigations into the Creation and Maintenance of Arable Fields on Swedish Farms

    University dissertation from Lund University

    Author : Lovisa Solbär; [2014]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landscape; timespace; time-geography; farming; boreal land use; time-economy; embedded values;

    Abstract : The human-induced open land (cropland, pasture) in the predominantly forested boreal landscapes relies on arable land use; it thus represents an active intervention to hold back forest regrowth. The thesis investigates the practical management decisions by landholders on discrete farms, which in Sweden often comprise both forest and arable lands. READ MORE

  2. 2. Anthropogenic Disturbances and Shifts in Tropical Seagrass Ecosystems

    University dissertation from Stockholm : Systemekologiska institutionen

  4. 4. Linking lake variability, climate, and human activity in Basotu, Tanzania

    University dissertation from Stockholm : Department of Physical Geography, Stockholm University

    Author : Lindsey Higgins; Lars-Ove Westerberg; Jan Risberg; Sarah Davies; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tanzania; crater lake; climate change; land-use change; water resources; environmental variability; diatoms; paleolimnology; chronology; naturgeografi; Physical Geography;

    Abstract : Paleoenvironmental investigations establish important baseline knowledge of the natural variability of lake systems, to better understand human impacts on the landscape, and the effects of climate change on water resources. By combining long-term environmental history with investigations into modern land use patterns and climatological events, a wider perspective can be reached that has practical applications in water governance.
