    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

  3. 3. 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.

    Sammanfattning : Biomaterials are materials that are specifically designed to be in contact with biological systems and have for a long time been used in medicine. Examples of biomaterials range from sophisticated prostheses used for replacing outworn body parts to ordinary contact lenses. Currently it is possible to create biomaterials that can e.g. LÄS MER

    Sammanfattning : A large number of emerging infectious diseases (including influenza epidemics) has been identified during the last century. The emergence and re-emergence of infectious diseases have a negative impact on global health. Influenza epidemics alone cause between 3 and 5 million cases of severe illness annually, and between 250,000 and 500,000 deaths. LÄS MER
