1. 1. 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 :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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.

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Land; Agrofuels; Ecologically unequal exchange; Environmental load displacement; Land grabbing; Malthus; Brazil; Ethanol; Resource wars; Land Use change; Indirect land use change;

   Sammanfattning : As a global society we are entering an era where land areas and land-based resources are coming to the fore once again for capital accumulation and economic growth, for the first time since the end of the 18th century when Malthus forecasted a contradiction between population growth and agricultural output. That constraint on economic growth, imposed by limited land areas, was overcome by the combination of fossil fuels (coal, oil) and appropriation of space overseas (colonialism, trade). LÄS MER

4. 3. Åter till släktens mark? : En studie av markåterlämningen i Estlands svenskbygder efter Sovjetunionens sammanbrott

The two first ones construct theoretical models for land use change between agriculture and forestry in the presence of lobbies representing both sectors. The third article tests empirically the hypothesis forwarded in the first essay. LÄS MER
