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. 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

4. 3. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

   Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

   Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER

5. 4. Road structures under climate and land use change : Bridging the gap between science and application

   Författare :Zahra Kalantari; Folkeson Lennart; Nachtnebel Hans-Peter; KTH; []
   Nyckelord :Adaptation; extreme rainfall events; runoff; land use; climate change; flood hazard; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Future changes in climate and land use are likely to affect catchment hydrological responses and consequently influence the amount of runoff reaching roads. Blockages and damage to under-dimensioned infrastructure can be extremely costly for the regions affected. LÄS MER

7. 5. 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.
