This topic examines the global governance of the Earth's oceans, specifically focusing on the changing trends, patterns, networks, and regulation of shipping (containers and oil tankers), the growth of smuggling and people trafficking, and the development of seafloor cable data networks, including their risks and protection.
Global flows of shipping and sea cables are fundamental to understanding the interconnected world economy. Shipping transports approximately 90% of global trade by volume, while submarine sea cables carry over 95% of international data traffic, including internet and financial transactions. This topic explores the geography of these flows, including major shipping routes (e.g., the Strait of Malacca, Suez Canal), chokepoints, and the network of fibre-optic cables that link continents. It also examines the economic, political, and environmental implications of these flows, such as the role of containerisation, the rise of megaships, and the vulnerability of cables to disruption.
In the WJEC A-Level Geography syllabus, this topic sits within the 'Global Governance' component, linking to themes of globalisation, interdependence, and power dynamics. Understanding shipping and cable networks helps students analyse how globalisation is physically sustained, who controls these networks (e.g., transnational corporations, states), and the geopolitical tensions that arise (e.g., the South China Sea disputes, cable tapping). It also connects to sustainability issues, such as carbon emissions from shipping and the environmental impact of cable laying on marine ecosystems.
Mastering this topic requires students to think spatially and critically about the hidden infrastructure that enables globalisation. By examining maps of shipping lanes and cable landings, students can identify patterns of connectivity and inequality—for example, why Africa has limited cable connections compared to Europe. This knowledge is essential for evaluating arguments about globalisation's benefits and drawbacks, and for understanding contemporary issues like the 2021 Suez Canal blockage or the role of cables in cyber warfare.
