  1. 11. PV water pumping systems for grassland and farmland conservation

    Författare :Pietro Elia Campana; Jinyue Yan; Bengt Perers; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Grassland degradation is considered as one of the worst environmental and economic problems in China because of the negative impacts on water and food security. The application of the photovoltaic water pumping (PVWP) technology for irrigation is an innovative and sustainable solution to curb the progress of grassland desertification and to promote the conservation of farmland in remote areas.

  3. 12. PV water pumping systems for agricultural applications

    Författare :Pietro Elia Campana; Jinyue Yan; Hailong Li; Lawrence Kazmerski; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Grassland and farmland degradation is considered as one of the worst environmental and economic threats for China. The degradation process negatively affects food and water security, economy, society and climate changes. LÄS MER

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

    Författare :Jan Pietroń; Jerker Jarsjö; Enrica Viparelli; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 14. Hydrological spreading of metal pollution and wetlands as nature-based solutions

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

    Sammanfattning : 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. LÄS MER

  7. 15. Sustainable Business Innovation of Photovoltaic Water Pumping Systems

    Författare :Chi Zhang; Jinyue Yan; Per Alvfors; Bin Chen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PV water pumping; Economic assessment; Ecological benefits; Business model innovation; Case study; Chemical Engineering; Kemiteknik;

    Sammanfattning : The development of renewable energy technology provides an effective approach to replace fossil fuels for greenhouse gas (GHG) emission. Technological innovation and transfer are the main driving forces in promoting renewable energy usage, because of the better efficiency and economic payback under an emission reduction target. LÄS MER
