  1. 1. Insufficient water supply in an urban area - case study : Tegucigalpa, Honduras

    Författare :Zairis Aida Coello Midence Balthasar; Jan-Erik Gustafsson; Berit Balfors; Mats Lannerstad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water supply; Honduras; SANAA; Tegucigalpa; water utility;

    Sammanfattning : Tegucigalpa, the capital of Honduras, has experienced an unsatisfied water demand during the last three decades. The state owned water utility in charge of the water supply of the country, SANAA, has faced this deficit by providing an intermittent water supply. LÄS MER

  3. 2. Green roof vegetation and storm water runoff quantity - Effects of plant traits, diversity and life strategies

    Författare :Joel Lönnqvist; Godecke-Tobias Blecken; Maria Viklander; Ishi Buffam; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : Green roofs have gained recognition and popularity globally for their potential to help mitigate the negative impacts of urbanization such as habitat loss and disruption of the water cycle caused by increased impervious surfaces. However, there is still a need to enhance our understanding of green roof vegetation dynamics and how they affect plant water use and hydrological function under varying environmental conditions.

  4. 3. Addressing water scarcity in the Bolivian Altiplano for sustainable water management

    Författare :Claudia Canedo Rosso; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Climatology; climate modes; Drought; Water balance; ENSO; Soil moisture; crop yield; Remote sensing; Bolivian highlands; arid and semiarid regions; Climate anomaly;

    Sammanfattning : Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. LÄS MER

  5. 4. Seasonality and variability of stratospheric water vapour

    Författare :Tongmei Wang; Abdel Hannachi; Qiong Zhang; Alexey Karpechko; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stratospheric water vapour; seasonality; variability; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Stratospheric water vapour (SWV) plays a critical role in the climate system by modulating the radiation budget and influencing the stratospheric chemistry. Studying changes of SWV on global scale is helpful for our understanding of climate change. LÄS MER

  7. 5. Plant aquaporins

    Författare :Ingela Johansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water deficit; calcium; plasma membrane; Plant biochemistry; channel; phosphorylation; Växtbiokemi;

    Sammanfattning : Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. LÄS MER
