  1. 16. Land Use Change in Space and Time : implications for plant species conservation in semi-natural grasslands

    Författare :Regina Lindborg; Ove Eriksson; Johan Ehrlén; Thomas Elmqvist; Markus Fischer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; management; restoration; landscape; history; Population viability analysis; seed-sowing; Primula farinosa; Campanula rotundifolia; grazing; fragmentation; extinction risk; Biology; Biologi;

    Sammanfattning : Land use change has during the last century altered the traditional rural landscape in Sweden, resulting in a major decline in species diversity. Traditional small-scale farming, with a remarkably high small-scale species richness, has changed in favour of rationalized agriculture, and many semi-natural grasslands, i.e. LÄS MER

  3. 17. 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

  5. 19. 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. 20. Forest and land use mitigation and adaptation in Sri Lanka – Aspects in the light of international climate change policies

    Författare :Eskil Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; land use; Sri Lanka; REDD ; CDM; deforestation; biomass; carbon stock; forest; carbon stock; biomass; forest; land use; deforestation; Sri Lanka; REDD ; CDM;

    Sammanfattning : As a developing island nation, Sri Lanka is vulnerable to the possible impacts of climate change. The land use and forestry sector accounts for a large part of Sri Lanka’s greenhouse gas emissions and can play a major part of Sri Lanka’s strategy to mitigate and adapt to climate change. LÄS MER
