The Ocean Century: Why the Future of Global Power Will Be Decided at Sea

Inaugural Article of the Ocean Geopolitics Centre

The twenty-first century is increasingly becoming the Ocean Century. While history has often been written through the rise and fall of continental empires, the defining strategic questions of our time are now unfolding across the world's oceans. From global trade and energy security to digital connectivity, food production, environmental sustainability, and international security, the maritime domain has emerged as the central arena of geopolitical competition and cooperation.

More than ninety per cent of international trade by volume is transported by sea. Thousands of commercial vessels connect continents every day, carrying the goods, resources, and technologies that sustain the global economy. Beneath the oceans lies an equally critical network of submarine communication cables that carries the overwhelming majority of the world's digital data, making the seabed one of the most strategically significant infrastructures of modern civilization.

At the same time, the oceans are becoming increasingly contested. Strategic competition among major powers is reshaping maritime regions from the Atlantic and the Arctic to the Indo-Pacific and the South China Sea. Critical underwater infrastructure, offshore energy resources, fisheries, rare marine minerals, and emerging maritime technologies have transformed the oceans into a domain where economic interests, national security, and environmental stewardship converge.

Climate change has further elevated the strategic importance of the oceans. Rising sea levels, changing weather patterns, ocean acidification, biodiversity loss, and the growing frequency of extreme weather events challenge governments and international organizations to rethink traditional approaches to maritime governance. The Blue Economy has consequently become more than an economic concept; it represents a framework for achieving sustainable growth while protecting marine ecosystems for future generations.

These developments demand informed analysis grounded in rigorous research and international dialogue. Ocean geopolitics is no longer a specialised field reserved for naval strategists or maritime lawyers. It has become an essential discipline for understanding international relations, economic resilience, technological innovation, and sustainable development.

It is within this context that the Ocean Geopolitics Centre (OGC) has been established as a SOAMAR Brasil in Portugal – Europe and the Community of Portuguese Language Countries (CPLP) initiative. The Centre seeks to provide an independent platform for research, strategic analysis, and policy dialogue on the issues shaping the global maritime domain. By bringing together scholars, policymakers, maritime professionals, industry leaders, and civil society, the Centre aims to foster multidisciplinary solutions to the complex challenges facing the world's oceans.

The Ocean Geopolitics Centre will publish research articles, policy briefs, strategic assessments, opinion essays, and special reports covering maritime security, naval strategy, ocean governance, international maritime law, the Blue Economy, critical infrastructure, emerging technologies, climate resilience, and global geopolitical developments. While maintaining a global outlook, the Centre is particularly committed to strengthening cooperation among the countries of the Community of Portuguese Language Countries (CPLP) and promoting dialogue across the Atlantic community.

Our oceans have always connected civilizations. Today, they also connect the world's greatest opportunities and its most pressing challenges. Understanding this reality is essential for building resilient economies, safeguarding international peace, protecting marine ecosystems, and ensuring that future generations inherit oceans that remain open, secure, and sustainable.

As the Ocean Geopolitics Centre begins its journey, we invite researchers, practitioners, institutions, and readers from around the world to join this conversation. Together, we can advance knowledge, encourage cooperation, and contribute to a future where the oceans continue to serve as a source of prosperity, security, and shared responsibility.

The future will not only be shaped on land. It will be shaped at sea.

Critical Underwater Infrastructure: The Hidden Battlefield Beneath the Oceans

  The Hidden Battlefield — Ocean Geopolitics Centre Beneath the world's oceans lies an extensive and largely invisible network upon which modern civilisation depends. Submarine fibre-optic cables, energy pipelines, electricity interconnectors, offshore installations and underwater sensor systems sustain global communications, financial markets, international trade, energy security and national defence. Although these systems remain hidden from public view, they have become strategic assets at the centre of twenty-first-century geopolitical competition. When national security is discussed, attention normally turns to armies, naval fleets, aircraft, satellites and territorial borders. However, some of the most important infrastructure supporting contemporary societies lies thousands of metres below the surface of the sea. This underwater domain is becoming a new strategic frontier in which technology, security, economic resilience and geopolitical rivalry increasingl...

  Maritime Tourism: Geopolitics, National Strategy and the Blue Economy in the Twenty-First Century Filipe Chaves Manoel Candeias (Founder Member of Ocean Geopolitics Centre) Part I – Maritime Tourism and National Maritime Strategy From Leisure Activity to Strategic Maritime Instrument For much of the twentieth century, maritime tourism occupied a relatively modest position within national economic planning. Governments largely regarded it as an extension of the hospitality industry, associated primarily with beaches, cruises, leisure navigation and coastal recreation. Academic literature similarly approached maritime tourism through the disciplines of economics, destination management and environmental conservation, emphasising visitor numbers, marketing strategies and the sustainable management of coastal ecosystems. While these perspectives undoubtedly contributed valuable insights into the development of the sector, they often overlooked a far more profound reality: mar...

The Intelligent Ocean: Education for a New Era of Ocean Science

    The Intelligent Ocean: Education for a New Era of Ocean Science By the Ocean Geopolitics Centre Ocean Intelligence, artificial intelligence, education and the future of global ocean governance The ocean is entering a new scientific and technological age. For centuries, humanity sought to understand the sea through direct observation, navigation, physical measurement and the gradual accumulation of oceanographic knowledge. Ships recorded currents, temperatures and depths. Coastal communities developed practical knowledge of tides and weather. Scientists later introduced increasingly sophisticated instruments capable of observing marine ecosystems, geological structures and atmospheric interactions. Today, however, the scale of ocean observation has changed profoundly. Satellites continuously monitor sea-surface temperatures, currents, waves, storms, chlorophyll concentrations and changes in sea level. Autonomous underwater vehicles explore depths that are inacce...
