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

    Författare :Emilie Lindkvist; Maja Schlüter; Jon Norberg; Örjan Ekeberg; James Dyke; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; 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; vetenskap om hållbar utveckling; Sustainability Science;

    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. Social-ecological dynamics in a highly regulated fisheries system - Sources of resilience and limits to command-and-control management

    Författare :Jonas Hentati-Sundberg; Henrik Österblom; Margit Eero; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; SOCIAL SCIENCES; Baltic Sea; resilience; social-ecological system; feed-backs;

    Sammanfattning : Sustainable governance of natural resources is challenged by the poor understanding of complex human-nature couplings. Major advancements in resilience theory, acknowledging the importance of social-ecological linkages and the self-organizing capacity of social-ecological systems, provides a new perspective on research in sustainability science.

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

    Författare :Hanna Sjögren; Per Gyberg; Cecilia Åsberg; Stacy Alaimo; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; HUMANITIES; HUMANIORA; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; HUMANIORA; NATURAL SCIENCES; SOCIAL SCIENCES; HUMANITIES; Environmental humanities; feminist theory; philosophy of education; posthumanities; teacher education; human-animal studies; sustainability; sustainable development; post-politics; social imaginaries; Humanistiska miljöstudier; feministisk teori; utbildningsfilosofi; posthumaniora; lärarutbildning; människa-djur-studier; hållbarhet; hållbar utveckling; postpolitik; imaginärer;

    Sammanfattning : Global initiatives regarding environmental change have increasingly become part of political agendas and of our collective imagination. In order to form sustainable societies, education is considered crucial by organizations such as the United Nations and the European Union. LÄS MER

  4. 4. Seeing and Knowing the Earth as a System : An Effective History of Global Environmental Change Research as Scientific and Political Practice

    Författare :Ola Uhrqvist; Eva Lövbrand; Bjön-Ola Linnér; Sabine Höhler; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Earth system; Global change; Governmentality; History of the present; history of environmental science; Jordsystemet; Globala miljöförändringar; Governmentality; nuets historia; miljövetenskapernas historia; internationella forskningsprogram; miljöpolitik;

    Sammanfattning : Previous research connecting scientific knowledge production with governing of the global environment usually start in international climate change negotiations and related assessments. From that vantage point Earth system science and models are studied as an expansion of Global Circulation Models. LÄS MER

  5. 5. Freshwater methane and carbon dioxide fluxes : Spatio-temporal variability and an integrated assessment of lake and stream emissions in a catchment

    Författare :Sivakiruthika Natchimuthu; David Bastviken; Åsa Danielsson; Peter A. Raymond; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Lakes; streams; spatio-temporal variability; CH4 flux; CO2 flux; gas transfer velocity; Sjöar; vattendrag; rumsliga och tidsmässiga variationer; CH4-flöden; CO2-flöden; gasutbyteshastighet;

    Sammanfattning : Freshwater bodies such as lakes and streams release the greenhouse gases methane (CH4) and carbon dioxide (CO2) into the atmosphere. Global freshwater CH4 and CO2 emissions have been estimated to be of a similar magnitude to the global land or ocean carbon sink, and are thus significant components of global carbon budgets. LÄS MER
