  2. 1. Changes in Hydrological Risk Perception and Implications for Disaster Risk Reduction

    Author : Elena Mondino; Giuliano Di Baldassarre; Johanna Mård; Teun Terpstra; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; risk perception; floods; droughts; disaster risk reduction; sociohydrology; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Abstract : Economic losses caused by hydrological extremes, such as floods and droughts, are exacerbating because of increased anthropogenic activities and global environmental changes. Understanding how individuals and communities interact with hydrological extremes thus becomes fundamental to develop effective strategies for disaster risk reduction. READ MORE

  4. 2. Impact of Climate Change on Extreme Events: Insights from Asia and Scandinavia

    Author : Dong An; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; extreme events; precipitation extremes; droughts; climate variability; ENSO; climate model; climate projection; the Asia-Pacific region; scandinavia;

    Abstract : As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. READ MORE

  5. 3. 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

  6. 4. Impacts of climate oscillation on precipitation and river flows of small scale river basins in Eastern Northeast Brazil

    Author : Denis Duda Costa; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Eastern Northeast Brazil; Droughts; Floods; Climate patterns; Hydrological model; Weather radar;

    Abstract : The Northeast region of Brazil is one of the most susceptible parts of the country to the effects of climate variability leading to severe droughts or extreme floods. Indeed, drought is a major issue due to a large semiarid area that covers 53% of the region, which determines the main climate characteristics of this region. READ MORE

  7. 5. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Author : Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Keywords : smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Abstract : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. READ MORE
