   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packaging; Features; Functions; Food; Organic; Life cycle; Eco; Sustainable Packaging; Development; Design;

   Sammanfattning : Previous research has argued that packaging has a great potential to contribute to sustainable development, but how to put this potential into practice is not yet fully explored. The theoretical foundation of the research presented is at the intersection of packaging logistics and sustainable development. LÄS MER

3. 7. Structural changes in marine ecosystems – the application of novel network approaches to understand marine regime shift

   Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Anthropogenic drivers, such as climate change and fishing, have severe, often unexpected impacts on marine ecosystems. Species responses to drivers may have cascading effects through ecological communities, potentially changing the structure and functioning of the food web. LÄS MER

   Sammanfattning : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.
