1. Reading the world as a network
How different places become interconnected by global interactions
Begin with flows rather than countries. Goods, capital, information and people move through networks; some places become powerful hubs while others remain peripheral. Use the map and overview resources to identify nodes, routes, chokepoints and uneven connectivity before moving into individual flows.
- A network is made of nodes connected by flows; the strongest nodes can organise and redirect flows far beyond their own territory.
- Globalisation increases connectivity, but distance, borders, infrastructure, regulation and geopolitical risk still matter.
- The same place can be central to one flow and peripheral to another, so connectivity should always be measured rather than assumed.
Flow-map warm-up
- Choose three different flows visible in the resources: one material, one financial and one human or informational.
- For each flow, identify an origin, destination, major node and one factor that speeds up or constrains movement.
- Write one hypothesis: which places gain most power from controlling global networks, and why?
2. Global trade in goods & services
Global trade in materials, manufactured goods and services
Trade is the most visible global flow, but its geography is changing. Compare merchandise, services and strategic goods, then use current WTO evidence to examine how tariffs, conflict, energy prices, AI-related trade and chokepoints can reshape global connections.
- Trade creates interdependence: disruption in one node or route can transmit impacts through distant economies.
- Trade volume, value and balance measure different things; students should distinguish them when using evidence.
- WTO data allow a current test of the claim that globalisation is weakening, reorganising or remaining resilient.
2026 trade pulse
- Use the WTO 2026 outlook and statistics dashboard to find two pieces of evidence about the direction of world trade.
- Identify one region, product group or service flow growing faster than the global picture and one growing more slowly.
- Decide whether the evidence is best described as deglobalisation, slowbalisation or re-globalisation. Defend your choice with data.

3. TNCs, FDI & outsourcing
Foreign Direct Investment and outsourcing by transnational corporations (TNCs), and ways in which this networks places and markets
TNCs turn maps of countries into production networks. Headquarters, research, finance, suppliers, assembly, logistics and consumers can all sit in different places. Follow one product through that network, then evaluate who captures the value and who carries the risks.
- FDI connects places through ownership and long-term investment, while outsourcing connects firms through contracts and supply chains.
- TNC decisions can create jobs, knowledge transfer and infrastructure, but also dependency, labour pressures and uneven value capture.
- UNCTAD's 2026 investment evidence shows why headline FDI growth can hide very uneven geographical outcomes.
Who really gains from a global product?
- Sketch the production network of a smartphone, trainer or IKEA product. Include headquarters, raw materials, component suppliers, assembly, transport and final market.
- Annotate where profit, skilled employment, low-paid employment and environmental costs are most likely to concentrate.
- Use one item of UNCTAD 2026 evidence to explain why FDI does not benefit all places equally.

Apple — a global supply chain
Trace how design, components, assembly, logistics and consumption link California, East Asia and global markets, then use the chain to examine labour, profit and corporate power.
- Spatial division of labour
- Value capture along a supply chain
- Corporate power and labour conditions
IKEA — suppliers, inventory and global strategy
Compare a very different production network built around a huge supplier base, standardised products, logistics and global retail markets.

- Logistics and inventory
- Global standardisation and local markets
4. Migration & remittances
International remittances from economic migrants
Migration produces a two-way flow: people move toward opportunities while money, ideas and social connections often move back toward origin communities. Remittances connect household decisions to the global economy and can be more stable than some other external financial flows.
- Measure remittances both as an absolute flow and as a share of GDP; the geographical story can look very different.
- Remittances can reduce household poverty and fund education, health or housing, but dependence and loss of skilled workers can create vulnerabilities.
- Formal statistics undercount some money and goods carried through informal channels.
Remittance geography
- Find the world's leading remittance recipients in total US dollars and then compare them with countries where remittances form a high share of GDP.
- Explain why the two rankings differ.
- Create a two-column judgement: three development benefits and three possible costs of migration/remittance dependence.

5. Aid, loans & debt relief
An overview of international aid, loans and debt relief
Financial flows are never simply 'money from rich countries to poor countries'. Separate grants, concessional loans, commercial lending, debt service, humanitarian aid and development assistance, then examine who chooses the destination and purpose of each flow.
- Aid can be bilateral or multilateral and may pursue humanitarian, development, diplomatic or strategic goals at the same time.
- Loans create future repayment flows; high debt servicing can constrain spending on health, education and infrastructure.
- Recent aid contractions make this a live example of how political choices in donor countries alter development possibilities elsewhere.
Follow the money
- Choose one lower-income country and identify recent aid, lending and debt-service flows affecting it.
- Classify each flow by actor, direction and purpose.
- Write a 150-word judgement: does the country's position in global financial networks increase its power or its dependence?
6. Illegal flows: the shadow networks
Illegal flows, including trafficked people, counterfeit goods, narcotics and wildlife
Illegal flows use many of the same infrastructures as legal globalisation: ports, roads, digital platforms, financial systems and migrant routes. South-East Asia provides an especially relevant contemporary lens because criminal markets now connect scam compounds, human trafficking, drugs, money laundering and digital fraud across borders.
- Illicit networks exploit differences in law, enforcement, income and governance between places.
- Legal and illegal flows overlap: people can be trafficked into scam centres, while profits are moved through global financial and crypto networks.
- Mapping only the commodity misses the network; identify recruiters, transit nodes, markets, finance and enforcement responses.
Network autopsy: South-East Asia 2026
- Use the UNODC 2026 threat assessment to choose one illicit flow: scam operations, trafficking, narcotics, wildlife or money laundering.
- Draw it as a network with origin/recruitment areas, transit nodes, destination/market, enabling technology and financial flows.
- Mark three points where governments or international organisations could disrupt the network. Rank them by likely effectiveness.

7. Synthesis: who controls the flows?
Synthesis of global networks and flows
Bring the unit back to power. Networks are not neutral pipes: governments, TNCs, financial institutions, platforms, criminal organisations and consumers all shape what moves, where it moves and who benefits. Strong answers connect several flows and evaluate how interdependence creates both opportunity and vulnerability.
- Power may come from producing a flow, controlling a node, setting the rules, financing the system or having alternatives when a network is disrupted.
- The most globally connected places can also be highly exposed to cascading disruption.
- Use named evidence from at least two different flows when evaluating the consequences of global interdependence.
Exam-ready synthesis
- Select one legal flow and one illegal flow from this page. For each, identify the main actors, nodes, winners, losers and vulnerabilities.
- Build a concept map linking networks, power, interdependence, inequality and resilience.
- Plan this response: ‘Global networks increase interdependence more than they increase equality.’ To what extent do you agree? Use at least three named examples.
