1. 1. Decision Support for Emergency Response to Multiple Natural Hazards : CHALLENGES AND NEEDS

   Författare :Viktor Sköld Gustafsson; Tobias Andersson Granberg; Mattias Hjerpe; Martin Waldemarsson; Margaret Mcnamee; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Global warming exceeding 1.5°C above pre-industrial levels will very likely lead to unavoidable increases of several climate hazards in the coming decades. Climate change phenomena can increase the risk of several extreme weather events, leading to risks of what is commonly considered as natural hazards, for instance landslides and forest fires.

3. 2. Violent natural resource conflicts : From definitions to prevention

   Författare :Marie K. Schellens; Belyazid Salim; Stefano Manzoni; Silja Bára Ómarsdottir; Päivi Lujala; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural resource conflicts; natural resources; violent conflict; criticality; definition; predictive modelling; early warning; causal network; prevention; Physical Geography; naturgeografi;

   Sammanfattning : General scientific consensus is growing that natural resources play an important role in violent conflicts. Both scarcity and abundance contribute to violent conflict, depending on the socio-economic and political conditions at play. LÄS MER

4. 3. Ab initio Lattice Dynamics : Hydrogen-dense and Other Materials

   Författare :Duck Young Kim; Rajeev Ahuja; Richard Needs; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Density functional perturbation theory; Hydrogen-dense materials; Phase transition; High pressure; Ab initio lattice dynamics; Superconductivity; Quasi-particle approximation; Physics; Fysik;

   Sammanfattning : This thesis presents a theoretical study of materials under high pressure using ab initio lattice dynamics based on density functional theory and density functional perturbation theory using both super-cell and linear response approach. Ab initio lattice dynamics using super-cell approach is applied to compare our theoretical predictions with experimental findings. LÄS MER

5. 4. Geographical Distribution of Disasters Caused by Natural Hazards in Data-scarce Areas : Methodological exploration on the Samala River catchment, Guatemala

   Författare :Agnes Jane Soto Gómez; Veijo Pohjola; Allan Rodhe; Giuliano di Baldassarre; Günter Blöschl; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural disasters; Guatemala; data-scarce areas; natural disaster science methods; natural disaster maps; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

   Sammanfattning : An increasing trend in both the number of disasters and affected people has been observed, especially during the second half of the 20th century. The physical, economic and social impact that natural hazards have had on a global scale has prompted an increasing interest of governments, international institutions and the academia. LÄS MER

7. 5. Stewardship in Swedish Baltic small-scale fisheries : A study on the social-ecological dynamics of local resource use

   Författare :Emma Björkvik; Wiebren J. Boonstra; Thorsten Blenckner; Jonas Hentati-Sundberg; McCay Bonnie; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; case study research; local ecological knowledge; marine environments; practice; semi-structured interviews; small-scale fisheries social-ecological system; social-ecological traps; structuration theory; traditional ecological knowledge; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Sustainability scholars frequently advocate for stewardship as a strategy to foster sustainable development. Stewardship broadly refers to the wise and responsible use of nature, and is considered necessary to ensure the long-term wellbeing of humans and that of life in general. LÄS MER
