The World's Web of Power
Global interactions, like trade and data flow, create a complex network connecting places, but this network is not equal. Some places hold more power and influence than others, shaping how resources, wealth, and opportunities are distributed globally.
Imagine the world is a giant social media network. Some users (core countries/global hubs like New York or London) are 'influencers' with millions of followers; their posts go viral and they set trends. Other users (peripheral countries) have few followers and mainly consume content created elsewhere. The influencers hold the power, shaping conversations and opportunities, while others are often left on the sidelines, reacting to changes rather than driving them.

First, identify the specific global network in the question (e.g., trade routes, internet cables, migration flows) and name the key players (e.g., TNCs, governments, IGOs).
- 2
Next, analyse the power relationships within this network. Who controls the flows? Who benefits most? Use concepts like core-periphery, TNC headquarters vs. production sites, or the digital divide.
- 3
Then, evaluate the human (e.g., trade blocs, political stability) and physical (e.g., resource location, coastline access) factors that have shaped this network and its power imbalances.
- 4
Finally, assess the consequences of these power dynamics. Consider the economic, social, and environmental impacts on different places, providing specific, located examples for both positive and negative effects.

Understanding Global Power and Networks
In geography, 'power' refers to the ability of a group or place to influence outcomes and control flows of capital, information, and people. This power is exercised through global networks – the arteries of globalisation. These networks consist of hubs (or nodes), which are centres of activity like global cities, and flows, which are the movements of goods, money, and ideas along links between these hubs.
Hard Power: Using military or economic means to influence others (e.g., trade tariffs, sanctions).
Soft Power: Using cultural or political influence to persuade others (e.g., the global appeal of a nation's media, education system, or values).
Key Global Flows: Capital (FDI, remittances), Commodities (raw materials, manufactured goods), Information (internet data, news), Migrants (economic migrants, refugees), and Tourists.
Network Structure: Power is concentrated in core hubs (e.g., New York, London, Tokyo) which control flows to and from the semi-periphery (e.g., Shanghai, São Paulo) and periphery (e.g., rural Sub-Saharan Africa).
Key Players Shaping Global Interactions
Transnational Corporations (TNCs) are arguably the most powerful non-state actors in the global economy. Through Foreign Direct Investment (FDI), outsourcing, and offshoring, they build complex production and supply chains that span the globe. Intergovernmental Organisations (IGOs) like the World Trade Organisation (WTO), International Monetary Fund (IMF), and World Bank set the 'rules of the game' for the global economy, often promoting free trade and neoliberal policies that facilitate TNC operations.
Influences on Global Networks
Global interactions are not frictionless; they are shaped by a range of enabling and constraining factors. Human factors include political decisions, economic policies, and technological advancements. Physical factors relate to the natural environment, such as resource distribution, climate, and topography.
Human Enablers: Transport technology (containerisation, jet aircraft), ICT development (internet, fibre optics), trade blocs (e.g., EU, ASEAN) reducing tariffs, government policies encouraging FDI.
Human Barriers: Political conflict and instability, protectionism (tariffs, quotas), censorship (e.g., China's 'Great Firewall'), concerns over migration.
Physical Enablers: Access to coastlines for shipping, availability of valuable natural resources (e.g., oil in the Middle East), favourable climate for tourism.
Physical Barriers: Landlocked countries face higher transport costs, extreme climates or difficult terrain (e.g., Himalayas, Amazon rainforest) hinder infrastructure development, natural hazards disrupt supply chains.
When asked to evaluate influences, always be specific. Don't just say 'technology'. Instead, explain how 'the development of standardised shipping containers' or 'the rollout of submarine fibre-optic cables' specifically impacted a particular flow, such as commodities or information. Use connecting phrases like 'This facilitated...' or 'This acted as a barrier to...'.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
Using a located example of one TNC, explain how its global network creates both opportunities and challenges for places at different stages of development. [10 marks]

A strong answer will name a TNC and provide specific, located details for both opportunities and challenges across at least two different places.
