Have we already entered a new epoch, the Anthropocene, dominated by the impact of human activities? What of the effects of increasing globalisation on the seas? Thirty-three experts on marine affairs and the law of the sea examine the emerging challenges for the World Ocean, inquiring into developments prompted by globalisation in central issue-areas of the law of the sea. These are explored systematically in sections on the key challenges and developments in the interface of science, economic uses and law (Part I); climate change and the oceans (Part II); sustainability of fisheries (Part III); challenges and responses related to global maritime transport (Part IV); and the regulatory responses to global challenges in seas surrounding Europe (Part V).
