  1. 1. Learning-by-modeling Novel Computational Approaches for Exploring the Dynamics of Learning and Self-governance in Social-ecological Systems

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

    Författare :Emilie Lindkvist; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complex adaptive systems; Renewable resources; Adaptive management; Small-scale fisheries; Artificial intelligence; Reinforcement learning; Agent-based modeling; agent-baserade modeller; artificiell intelligens; social-ekologiska system; komplexa adaptiva system; förnyelsebara naturresurser; adaptiv förvaltning; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : As a consequence of global environmental change, sustainable management and governance of natural resources face critical challenges, such as dealing with non-linear dynamics, increased resource variability, and uncertainty. This thesis seeks to address some of these challenges by using simulation models. LÄS MER

  2. 2. The Nitrogen Cycle in Soil - Climate Impact and Methodological Challenges in Natural Ecosystems

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

    Författare :Anna-Karin Björsne; Göteborgs universitet.; Gothenburg University.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen cycle; 15N tracing experiments; gross N transformation rates; climate change; climate treatments; mineralization; nitrification; forest fertilization; nitrous oxide emissions; boreal forest soil; tree species; soil organic matter; C:N ratio;

    Sammanfattning : Nitrogen (N) is a fundamental element for life, and limiting in many terrestrial ecosystems. In non-N-fertilized ecosystems, the N inputs can be low, and the nutrient availability for plants is determined by the internal cycling of N. LÄS MER

  3. 3. Development of a Risk-Based Decision Model for Prioritizing Microbial Risk Mitigation Measures in Drinking Water Systems

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Viktor Bergion; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; quantitative microbial risk assessment; microbial risks; pathogens; water quality modelling; drinking water system; cost-benefit analysis; decision support; drinking water; microbial risk;

    Sammanfattning : Risk management of drinking water systems is crucial since our society relies on these systems to be robust and sustainable to supply safe drinking water now and to future generations. Pathogens may spread in drinking water systems and cause waterborne outbreaks resulting in human suffering and large costs to the society. LÄS MER

  4. 4. Sustainability for Whom? The Politics of Imagining Environmental Change in Education
