  2. 1. Sediment transport from source to sink in the Lake Baikal basin : Impacts of hydroclimatic change and mining

    Author : Jan Pietroń; Jerker Jarsjö; Enrica Viparelli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment transport; human impact; hydroclimatic change; surface mining; metal-enriched sediment; Lake Baikal; the Selenga River; the Selenga Delta; Physical Geography; naturgeografi;

    Abstract : Different magnitude, intensity and timing of precipitation can impact runoff, hillslope erosion and transport of sediment along river channels.  Human activities, such as dam construction and surface mining can also considerably influence transport of sediment and sediment-bound contaminants.

  4. 2. Intensifying Agricultural Water Management in the Tropics : A cause of water shortage or a source of resilience?

    Author : Yihun Dile; Johan Rockström; Louise Karlberg; Mekonnen Gebremichael; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water harvesting; Climate change; Climate variability; Multi criteria evaluation; SWAT; CN; sub-Saharan Africa; Upper Blue Nile; Lake Tana basin; naturresurshushållning; Natural Resources Management;

    Abstract : Frequent climatic shocks have presented challenges for rainfed agriculture in sub-Saharan Africa. Appropriate water management practices are among the solutions to the challenges. The role of water harvesting in achieving sustainable agricultural intensification and specified resilience was explored. READ MORE

  5. 3. Fractionation of the stable silicon isotopes studied using MC-ICP-MS : analytical method developments and applications in geochemistry

    Author : Emma Engström; Ben Reynolds; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : In spite of the high Si abundance in natural systems, expected significant mass-dependent fractionations, and the importance of the element in many areas of the Earth sciences (focusing on e.g. READ MORE

  6. 4. Hydrological spreading of metal pollution and wetlands as nature-based solutions

    Author : Josefin Thorslund; Jerker Jarsjö; Mario Schirmer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical Geography; naturgeografi;

    Abstract : The quality of the Earth’s water resources have deteriorated due to human impacts. A key scientific challenge is to understand, quantify and predict the water-borne spreading of pollutants at relevant scales for freshwater management and water quality restoration programs. READ MORE
