What Is Globalisation? KS3 Geography Explained

Globalisation is the process by which people, places, and economies across the world are becoming increasingly connected and interdependent through trade, communication, migration, and the spread of ideas. It means that events in one country — a factory fire in Bangladesh, a harvest failure in Brazil — can affect everyday life in the UK within hours.

What causes globalisation?

Globalisation is not a single cause but the result of several reinforcing processes happening simultaneously.

Improvements in transport

Containerisation revolutionised world trade from the 1950s onwards. Standardised steel containers allow goods to be loaded onto a ship in Shanghai, unloaded onto a train in Rotterdam, and delivered to a supermarket in Manchester without ever being individually handled. The cost of shipping one tonne of goods fell by over 70% between 1950 and 2000, according to economic historians.

Aircraft made long-distance travel affordable for millions. Today over 4 billion passengers fly per year, spreading people, ideas, and investment across the globe.

The internet and communication technology

The internet has transformed globalisation since the 1990s. A company in the UK can now manage a factory in Vietnam, design a product in Germany, and sell it to customers in Australia — all in real time. The cost of international communication has fallen close to zero.

Transnational corporations (TNCs)

Transnational corporations are companies that operate in more than one country. Examples include Apple, Nike, Toyota, and Shell. TNCs chase the lowest production costs, the best-skilled workers, and the most favourable tax arrangements across the globe. Where they invest shapes the economic geography of entire regions.

Free trade agreements and organisations

Organisations such as the World Trade Organisation (WTO) — founded in 1995 — have reduced trade barriers (tariffs and quotas) between countries. The EU single market is the most integrated example of free trade in practice: goods, services, money, and people move freely across 27 countries.

What are the effects of globalisation?

Effects must always be evaluated for different groups — what is beneficial for one group can be harmful for another. Geographers often use the SEEP framework (Social, Economic, Environmental, Political) to organise this analysis.

Economic effects

Positive:

Consumers in wealthy countries benefit from lower prices for goods manufactured in countries with lower labour costs.

Low- and middle-income countries (LMICs) gain investment, jobs, and technology transfer from TNCs.

Global trade has lifted hundreds of millions of people out of extreme poverty. The World Bank estimates the global extreme poverty rate fell from 36% in 1990 to under 10% by 2015.

Negative:

Manufacturing jobs have moved from the UK and other high-income countries to lower-wage economies. Former industrial cities like Sheffield and Stoke-on-Trent lost tens of thousands of jobs in steel and ceramics between the 1970s and 1990s as production moved abroad.

Profits made by TNCs in LMICs are often repatriated (sent back) to the headquarters country rather than reinvested locally.

Workers in some export zones face low wages, long hours, and poor conditions — often enforced by weak labour laws.

Social and cultural effects

Positive:

Increased migration allows people to move for work, study, and family — raising living standards for migrants and sending remittances home.

Cultural exchange enriches societies: food, music, sport, and ideas spread across borders.

Negative:

Local cultures can be overwhelmed by dominant global cultures, particularly US-origin media, fast food, and fashion — a process sometimes called cultural homogenisation.

Migration can create social tensions over housing, services, and national identity.

Environmental effects

Globalisation has an enormous environmental footprint.

Carbon emissions from shipping and aviation: International shipping alone accounts for around 2.5% of global greenhouse gas emissions (International Maritime Organisation, 2020).

Deforestation: Global demand for soya (animal feed), palm oil, and beef has driven large-scale deforestation in the Amazon and in Indonesia.

Waste and pollution: Manufacturing in countries with weaker environmental regulations can result in pollution being effectively "exported" from richer to poorer countries.

Key case study — Bangladesh and the garment industry

Bangladesh is one of the world's largest garment exporters, supplying clothing to major UK retailers. The garment industry employs around 4 million workers, the majority of them women, and accounts for roughly 80% of Bangladesh's export earnings.

Benefits: Employment has helped millions of Bangladeshi women gain economic independence and has driven down poverty rates in urban areas. The country's GDP per capita has risen steadily since the 1990s as the industry expanded.

Costs: The collapse of the Rana Plaza building in Dhaka on 24 April 2013 killed 1,134 garment workers and injured over 2,500, making it one of the deadliest industrial disasters in history. The building's owners had ignored warnings about structural cracks. The disaster focused global attention on the conditions in fast-fashion supply chains.

Key term table

Term | Definition
Globalisation | The process by which the world becomes more interconnected through trade, communication, and migration
Transnational corporation (TNC) | A company that operates in more than one country
Free trade | Trade between countries with minimal barriers such as tariffs or quotas
Outsourcing | When a company moves part of its production to another firm, often in a different country
Remittances | Money sent home by migrants working abroad
Cultural homogenisation | The spread of a single (often Western) culture at the expense of local cultures

What does the national curriculum say about globalisation?

The DfE's KS3 geography programme of study (Department for Education) requires pupils to understand how human processes (including economic activity and population movements) interact with physical geography, and to study the interconnection of places and environments at a range of scales. Within the Key Stage 3 and 4 national curriculum, globalisation is a core concept that underpins many geography topics — from urban change to climate change — and is explicitly assessed at both GCSE and A-level.

Frequently asked questions

Is globalisation good or bad?

Globalisation has both benefits and costs, and these are experienced differently depending on who you are and where you live. Lower-income consumers in wealthy countries benefit from cheaper goods; workers in manufacturing LMICs gain employment; but former industrial workers in those wealthy countries may lose jobs, and factory workers in supply chains may face poor conditions. Good geography answers acknowledge this complexity rather than giving a simple verdict.

What is a transnational corporation and why do they matter for globalisation?

A transnational corporation (TNC) is a company that operates across more than one country — such as Apple, which designs products in the USA, manufactures them in China and Taiwan, and sells them worldwide. TNCs matter because where they choose to locate factories and offices shapes the economic development of entire regions. Their decisions to invest or disinvest can create or destroy thousands of jobs.

What is the difference between globalisation and international trade?

International trade is the buying and selling of goods and services between countries, and has existed for thousands of years. Globalisation describes the broader, accelerating process by which countries are becoming deeply interdependent — not just in trade, but in culture, communication, migration, and politics. International trade is one driver of globalisation, but globalisation is much wider than trade alone.

How does globalisation affect the environment?

Globalisation increases the environmental footprint of production and consumption. Shipping and aviation create significant carbon emissions. Global demand for agricultural products has driven deforestation in Brazil and Indonesia. Manufacturing in countries with weaker environmental regulations can shift pollution rather than reduce it. However, globalisation also enables the rapid spread of renewable energy technologies and environmental knowledge across countries.
