  2. 1. Hydro-Climatic Variability and Change in Central America : Supporting Risk Reduction Through Improved Analyses and Data

    Author : Beatriz Quesada-Montano; Sven Halldin; Hugo G. Hidalgo; Ida K. Westerberg; Fredrik Wetterhall; Denis Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central America; climate variability; disaster risk reduction; droughts; drought indices; floods; hydrological model; process constraints; statistical downscaling; uncertainty; ungauged basins; water resources.; Hydrology; Hydrologi;

    Abstract : Floods and droughts are frequent in Central America and cause large social, economic and environmental impacts. A crucial step in disaster risk reduction is to have a good understanding of the causing mechanisms of extreme events and their spatio-temporal characteristics. READ MORE

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

    Author : Claudia Canedo Rosso; Avdelningen för Teknisk vattenresurslära; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Effects of drought on boreal forest understory species

    Author : Irena A. Koelemeijer; Kristoffer Hylander; Johan Asplund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity conservation; boreal forests; bryophytes; canopy cover; climate change; drought; extreme climatic events; forest management; forest understory; fungi; lichens; plants; rainout shelter; soil communities; soil moisture; transplant experiment; Ecology and Evolution; ekologi och evolution;

    Abstract : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.

  6. 4. Modeling long-term variability and change of soil moisture and groundwater level - from catchment to global scale

    Author : Lucile Verrot; Georgia Destouni; Aldo Fiori; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrology; physically-based model; groundwater; soil moisture; Physical Geography; naturgeografi;

    Abstract : The water stored in and flowing through the subsurface is fundamental for sustaining human activities and needs, feeding water and its constituents to surface water bodies and supporting the functioning of their ecosystems. Quantifying the changes that affect the subsurface water is crucial for our understanding of its dynamics and changes driven by climate change and other changes in the landscape, such as in land-use and water-use.

  7. 5. The use of global data to uncover how humans shape flood and drought risk

    Author : Sara Lindersson; Giuliano Di Baldassarre; Johanna Mård; Luigia Brandimarte; Brett Sanders; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural hazards; hydrological disasters; environmental geography; global geospatial data; international databases; disaster losses; disaster consequences; water management; dams and reservoirs; floodplains; hydrological drought; social vulnerability; economic inequality; Anthropocene; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Abstract : The human consequences of flood and drought disasters are widespread and detrimental. Large-scale studies, drawing on global geodata products and international databases, can systematically examine how anthropogenic megatrends shape disaster risk and test the generalisability of findings from other scientific methodologies.
