1. 1. Land Matters : Agrofuels, Unequal Exchange, and Appropriation of Ecological Space

   Författare :Kenneth Hermele; Humanekologi; []
   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

3. 2. 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

4. 3. Essays on the Political Economy of Land Use Change

   Författare :Johanna Jussila Hammes; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land tax; technological change; land use; deforestation; agricultural trade liberalization; Doha round; Dutch disease; perceived comparative advantage; EU-15; panel data;

   Sammanfattning : This thesis consists of three articles. 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

5. 4. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

   Författare :Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

   Sammanfattning : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

7. 5. Urban Growth Modeling Based on Land-use Changes and Road Network Expansion

   Författare :Yikang Rui; Yifang Ban; Henning Sten Hansen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; urban growth sprawl; land-use simulation; multi-agent system; road network pattern; space syntax; complex networks; evolving weighted networks; nonlinear growth; local world; hierarchy; self-organized; local optimization; morphological changes; street centrality; adaptive kernel density estimation; dual representation;

   Sammanfattning : A city is considered as a complex system. It consists of numerous interactivesub-systems and is affected by diverse factors including governmental landpolicies, population growth, transportation infrastructure, and market behavior. LÄS MER
