Mastering Globalisation and migration: Edexcel IGCSE Geography Study Notes

Your phone was designed in California, assembled in China, and delivered to your door by a company headquartered in Seattle. That is globalisation in a single sentence. This section of the Edexcel IGCSE Geography specification unpacks how the world economy has become interconnected, why people move across borders, and what it all means for different countries.

The IGCSE 4GE1 globalisation and migration section covers three areas: the factors driving globalisation and migration, the varying impacts of globalisation across the world, and how different countries respond to migration and tourism. These Edexcel IGCSE Geography notes break it all down in plain language, with case studies, common mistakes and self-check questions.

The rise of the global economy

Globalisation is the process by which the world's economies, cultures and populations have become increasingly interconnected. It has been driven by several factors:

• Trade: International trade in goods and services has expanded dramatically, supported by trade agreements that reduce tariffs and barriers.
• Foreign investment: Companies invest in other countries to access cheaper labour, new markets or raw materials.
• Aid: Development aid flows from wealthier countries to poorer ones, sometimes tied to conditions that open markets.
• Labour: Workers migrate across borders to fill skills gaps or seek better wages, creating a global labour market.
• Modern transport: Container shipping, air freight and low-cost airlines have made moving goods and people faster and cheaper than ever before.
• Information technologies: The internet, mobile phones and satellite communications allow instant global communication, enabling companies to coordinate operations across multiple countries.

The growth of production and commodity chains illustrates how globalisation works in practice. A commodity chain traces a product from raw material to finished good. A cotton T-shirt might involve cotton grown in India, spun into yarn in Bangladesh, cut and sewn in Vietnam, and sold in the UK. Each stage adds value, and the profits are distributed unevenly along the chain, with the greatest share typically going to the brand owner in the developed world.

Global institutions

Three institutions play key roles in shaping the global economy:

TNCs are particularly important for the exam. Think of companies like Nike, Samsung or Unilever. They locate different parts of their operations in different countries based on factors such as labour costs, market access, government incentives and infrastructure quality. The benefits to host countries include job creation, technology transfer and improved infrastructure. The costs can include low wages, poor working conditions, environmental damage and profit being repatriated to the TNC's home country rather than staying in the local economy.

Migration: push and pull factors

Migration is the movement of people from one place to another. The specification requires you to understand the social, economic and political push and pull factors that influence different types of migration.

Types of migration include voluntary (chosen) and forced (compelled by war, disaster or persecution), national (within a country) and international (across borders), and rural-urban (from countryside to city). The specification also mentions medical migration (healthcare professionals moving to countries with better pay), sport migration (athletes relocating to compete at higher levels), tourism (temporary movement for leisure) and economic migration (moving for work).

Impacts of globalisation

The Edexcel IGCSE Geography globalisation and migration content asks you to understand how globalisation affects different groups of people, including the benefits and costs of hosting TNCs.

Benefits to host countries: Job creation, improved infrastructure (roads, ports, telecommunications), technology and skills transfer, tax revenue, integration into the global economy.

Costs to host countries: Low wages and poor working conditions in some factories, environmental damage from industrial activity, profits sent back to the TNC's home country, local businesses unable to compete, cultural homogenisation as global brands replace local traditions.

Impacts of migration

Migration affects both the origin country and the destination country:

• Origin country: Loses young, skilled workers (brain drain); receives remittances (money sent home by migrants, which can be a major income source); reduced pressure on services and resources; ageing population if only the young leave.
• Destination country: Gains workers to fill skills gaps; cultural enrichment and diversity; pressure on housing, schools and healthcare; potential social tension if integration is poorly managed.

Rural-urban migration within developing countries is one of the main drivers of rapid urbanisation and the growth of informal settlements (slums) in megacities such as Lagos and Dhaka.

Impacts of global tourism

Tourism is one of the world's largest industries. Mass tourism brings both benefits and problems to destination areas:

• Economic benefits: Job creation (hotels, restaurants, tour operators), foreign currency earnings, investment in infrastructure.
• Economic costs: Seasonal employment, low-paid jobs, economic leakage (profits going to foreign-owned hotel chains), overdependence on tourism.
• Environmental benefits: Revenue for conservation (national parks, wildlife reserves).
• Environmental costs: Habitat destruction from resort construction, water overuse, waste generation, carbon emissions from flights.
• Social benefits: Cultural exchange, improved local services funded by tourism revenue.
• Social costs: Overcrowding, disruption to local communities, commodification of culture.

Responses to migration and tourism

The specification asks how geopolitical relationships between countries are important in managing trade, migration and tourism. Trade agreements (EU single market, NAFTA/USMCA), visa policies, border controls and international cooperation all shape how goods and people move across borders.

You need a case study of long-term migration management in a named country. Germany provides a strong example: the influx of Syrian refugees from 2015 onward led to a comprehensive integration programme including language courses, vocational training, housing allocation and employment support. The response was shaped by Germany's ageing population (migrants helped fill labour shortages) and its political commitment to humanitarian obligations. Challenges included public debate about cultural integration, pressure on local services and rising political tensions.

You also need case studies of sustainable tourism. The UK promotes sustainable tourism through the National Trust, Green Tourism certification and local initiatives that encourage visitors to travel by public transport, stay in locally owned accommodation and support local businesses. In a developing country, Kenya has developed community-based ecotourism programmes in which local Maasai communities manage wildlife conservancies, set visitor limits, share revenue fairly and protect habitats. This model generates income while minimising environmental damage and keeping control in the hands of local people. The globalisation and migration Edexcel IGCSE questions on sustainability reward precisely this kind of detailed, place-specific comparison.

Fieldwork connections

Paper 2 may test fieldwork related to the impacts of tourism or migration on a local area. Relevant techniques include designing questionnaires to survey residents or visitors about their experiences, conducting environmental quality assessments in tourist areas, comparing land use in tourist-heavy zones with quieter districts, and using secondary data (visitor numbers, employment statistics, migration records) to identify trends. Be prepared to explain how you would choose a sample, present your data and evaluate the reliability of your findings. Questions may also ask you to suggest improvements to a proposed investigation or to explain why a particular data collection method might produce biased results.

Common mistakes

• Confusing globalisation with urbanisation. Globalisation is about international connections (trade, investment, migration). Urbanisation is about the growth of cities. They are related but not the same thing.
• One-sided TNC answers. Always discuss both benefits and costs. A balanced evaluation earns more marks than a list of advantages alone.
• Listing push-pull factors without explaining them. Naming "poverty" as a push factor is not enough. Explain how poverty drives migration: "Low wages and lack of employment in rural areas push young people toward cities where factory work offers higher, more reliable income." The Edexcel IGCSE Geography explained answers that score highest always include this kind of reasoning.

Practice questions to test yourself

Try these Edexcel IGCSE Geography practice questions:

• Explain how TNCs contribute to globalisation. Use a named example of a TNC and a host country.
• Describe the push and pull factors that have influenced international migration over the last 50 years.
• Evaluate the positive and negative impacts of mass tourism on a named destination area.
• Compare how a developed country and a developing country have responded to the challenges of long-term migration or sustainable tourism.

Self-check questions

1. Name three pull factors that attract rural-to-urban migrants in a developing country, and explain how each contributes to urban growth.
2. Describe two environmental problems caused by rapid urbanisation and suggest one management strategy for each.
3. Compare the causes of urban sprawl in a developed country with those in a developing country. What do they have in common, and where do they differ?
4. A city government is planning a new housing development on the urban fringe. Outline the arguments for and against this proposal from an environmental perspective.

These Edexcel IGCSE Geography revision notes cover the full globalisation and migration section. The exam rewards students who can link concepts (globalisation drives migration, migration shapes urbanisation, tourism creates both opportunities and problems) and support those links with real-world evidence.
