    Abstract : Since ancient times, roads have tied people and cultures together. Roads have been createdwith the aim of facilitating trade and cultural exchange among different regions in the world. READ MORE

  4. 2. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Author : Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Abstract : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. READ MORE

  5. 3. Hydrological Modeling for Climate Change Impact Assessment : Transferring Large-Scale Information from Global Climate Models to the Catchment Scale

    Author : Claudia Teutschbein; Jan Seibert; Chris Kilsby; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bias Correction; Climate Change; Climate Models; Ensembles; GCM; HBV; Hydrological Modeling; Precipitation; RCM; Split Sample Test; Streamflow; Sweden; Temperature; Uncertainty; Physical Geography; naturgeografi;

    Abstract : A changing climate can severely perturb regional hydrology and thereby affect human societies and life in general. To assess and simulate such potential hydrological climate change impacts, hydrological models require reliable meteorological variables for current and future climate conditions. READ MORE

  6. 4. Urban design of winter cities : Winter season connectivity for soft mobility

    Author : David Chapman; Kristina Nilsson; Agatino Rizzo; Agneta Larsson; Dag Kittang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban form; urban design; seasonal climate variation; winter cities; climate change; Architecture; Arkitektur;

    Abstract : All across the world the form of the built environment is playing a crucial role as enabler or inhibitor for urban outdoor activity such as soft mobility. Urban form can make it more attractive for people to be mobile outdoors and playing a role in the public life, or it can put people off venturing outside. READ MORE

  7. 5. Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene : Insights from biomarkers and climate model simulations

    Author : Lars Petter Hällberg; Malin Kylander; Frederik Schenk; Rienk Smittenberg; David Naafs; Stockholms universitet; []
