1. 1. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Emilie Åström; [2022]
   Nyckelord :acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Sammanfattning : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. LÄS MER

3. 2. Twenty-First Century Drought Projections in Swedish Catchments

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Elise Jonsson; [2022]
   Nyckelord :Drought; climate change; drought index; climate models; catchments; societal functions; Torka; klimatförändring; torkindex; klimatmodeller; avrinningsområde; samhällsfunktioner;

   Sammanfattning : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. LÄS MER

4. 3. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

   Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

   Författare :Simon Hannus; [2021]
   Nyckelord :Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

   Sammanfattning : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

5. 4. Impact of Drought on Water Demand  in Los Angeles, USA

   Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Kiara Pashley; [2021]
   Nyckelord :drought; socio-hydrology; water demand; Los Angeles; torka; socio-hydrologi; vattenefterfrågan; Los Angeles;

   Sammanfattning : Los Angeles has historically been subjected to droughts and water shortages. This has led the city to acquire distant water resources, allowing the city to grow extensively. Today, the city is dependent on large water infrastructure to supply water over distances of hundreds of kilometres. LÄS MER

7. 5. Effects of drought on waterchemistry in a boreal streamnetwork

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Enrique Gómez de Salazar Martínez; [2021]
   Nyckelord :: drought; boreal streams; Krycklan Catchment Study; land cover; biogeochemistry;

   Sammanfattning : Hydrological drought at high latitudes represents a rising environmental hazard induced byglobal climate change. Yet, we still know little about how drought events influence thebiogeochemistry of boreal streams. LÄS MER
