The Development of the EU as a Sea-Policy Actor explores the marine and maritime policies of the European Union (EU), including fisheries, maritime transport, marine environment and maritime safety policies. These policies have made the EU an important sea-policy actor internally and externally. The author places the EU’s sea-related policies in a historical context and discusses the explanatory power of various political science theories, international relations and regional integration theories in particular. What emerges clearly is that no one theory can explain the observed developments, but that we need to combine theories to get a fuller understanding and explanation of what is also referred to as the Blue Europe. Entrepreneurship and small business management educators, researchers, scholars, university administrators and mentors and advisors to entrepreneurs will glean the latest insights, programming overviews, best practices and contemporary perspectives that have real applications in these fields.
