    Sammanfattning : This thesis presents how experimental results, from wave power research performed offshore at the Lysekil research site, were obtained. The data were used to verify theoretical models as well as evaluate the feasibility of wave power as a future sustainable energy source. LÄS MER

  7. 5. Unravelling Sustainability : The complex dynamics of emergent environmental governance and management systems at multiple scales

    Författare :Lucas Dawson; Ingrid Stjernquist; Marine Elbakidze; Raimonds Ernsteins; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Integrated adaptive environmental governance and management; Social-ecological system dynamics; Complex systems; Sustainability transitions; Sustainability strategies; Multi-level governance; Causal loop diagrams; Green Infrastructure; Landscape restoration; Habitat restoration; Biodiversity conservation; Comprehensive planning; Stakeholder participation; System thinking; Water Framework Directive; Sustainable water governance; Collaborative learning; Communities of practice; Knowledge management; Physical Geography; naturgeografi;

    Sammanfattning : This thesis adopts a complex systems approach to investigate the dynamic emergence of sustainable environmental governance and management systems in multiple contexts in Europe. Accelerating rates of environmental degradation across the world have called the legitimacy of previous environmental governance and management arrangements into question. LÄS MER
