   Sammanfattning : New technologies for the extraction of valuable ocean resources are emerging: renewable ocean energy. Ocean energy technologies have so far primarily been developed in industrialized countries but will be deployed in both industrialized and developing countries. LÄS MER

4. 13. From Corals to Corporations : Social-ecological dynamics in the Anthropocene ocean

   Författare :Jean-Baptiste Jouffray; Magnus Nyström; Toby Gardner; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anthropocene; Ocean; Coral reef; Finance; Regime shift; Sustainability; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : The ocean has always been of paramount importance for the development of human civilisation. Today more than ever, the prospect of a new era of ‘blue growth’ poses great sustainability and governance challenges as marine ecosystems worldwide face unprecedented cumulative pressures from local human impacts, global climate change and distal socioeconomic processes.
