What you'll learn
Global development is about the differences in wealth and quality of life between countries, why those differences exist, and how they can be reduced. This guide covers what you need for Edexcel GCSE Geography: the meaning and measures of development (economic, social and composite measures such as the HDI), the causes of uneven development — physical, historical, economic and political — the consequences of the development gap, theories of development, the different approaches to development (top-down and bottom-up), and how an emerging country is developing, using India as the main example. It also covers the role of trade, aid, investment and transnational corporations (TNCs).
Exam questions often ask you to interpret development data, explain why countries develop at different rates, and evaluate strategies for reducing the gap. Use specific evidence and consider both benefits and drawbacks.
Key terms and definitions
Development — Improvement in people's standard of living and quality of life.
GDP / GNI per capita — The total value of goods and services produced by a country (GNI includes income from abroad), divided by the population.
Purchasing power parity (PPP) — An adjustment that takes into account differences in the cost of living between countries.
Human Development Index (HDI) — A composite measure combining life expectancy, education and income, on a scale from 0 to 1.
Development gap — The difference in wealth and quality of life between richer and poorer countries.
Developed, emerging and developing countries — Countries at high, rising and lower levels of development.
Colonialism — The control of one country by another, often for its resources.
Transnational corporation (TNC) — A company that operates in more than one country.
Foreign direct investment (FDI) — Investment by a company or individual in one country into businesses in another.
Top-down development — Large-scale projects planned and funded by governments, international organisations or large companies.
Bottom-up development — Small-scale projects led by local communities, often with charities, to meet local needs.
Aid — Help given by one country or organisation to another, as money, goods, expertise or loans.
Core concepts
Measuring development
Economic measures include GDP per capita and GNI per capita, often adjusted for PPP. They are easy to compare but are averages that hide inequality within a country and ignore quality of life.
Social measures include life expectancy, infant mortality (deaths of babies under one per 1,000 live births), literacy rate, access to clean water, doctors per 1,000 people and birth rate. They show quality of life more directly.
Composite measures combine several indicators. The Human Development Index combines life expectancy, years of schooling and income per person, giving a fuller picture than a single measure. Even so, HDI does not measure inequality, political freedom or environmental quality.
Using several measures together gives the most accurate view of development.
Causes of uneven development
Physical factors:
- Climate — extreme heat, drought or unreliable rainfall can limit farming and cause food shortages.
- Natural hazards — repeated floods, earthquakes or cyclones destroy infrastructure and set development back.
- Landlocked location — countries without coastlines find trade more expensive.
- Disease — tropical diseases such as malaria reduce people's ability to work and study.
Historical factors:
- Colonialism — many countries were controlled by European powers, which extracted raw materials and set up economies based on exporting primary products, leaving weak industry and infrastructure after independence.
Economic factors:
- Trade — developing countries often export raw materials, which have low and fluctuating prices, and import manufactured goods, which are more expensive. Trade barriers and subsidies in richer countries can make it hard to compete.
- Debt — loans taken out for development projects can lead to heavy repayments that take money away from health and education.
Political factors:
- Conflict — war destroys infrastructure, displaces people and diverts spending.
- Corruption and poor governance — money for development may be misused, and investors may be discouraged.
Consequences of the development gap
The development gap affects people's health, education, income and opportunities. It can lead to international migration as people seek work in richer countries; remittances (money sent home by migrants) are an important income for many developing countries. Within countries, it can create regional inequality between cities and rural areas.
Theories of development
Rostow's model suggests countries pass through five stages: traditional society, preconditions for take-off, take-off, the drive to maturity, and the age of high mass consumption, as investment and industry grow. Critics argue it is based on the experience of Western countries and ignores external factors such as colonialism and trade.
Frank's dependency theory argues that richer "core" countries have kept poorer "periphery" countries underdeveloped by exploiting their resources and labour through colonialism and unequal trade. Critics note that some countries, such as South Korea and China, have developed rapidly despite this.
Approaches to development
Top-down development involves large-scale projects such as dams, motorways, power stations and industrial zones, funded by governments, international organisations such as the World Bank, or TNCs.
- Advantages: can transform national infrastructure and the economy; create many jobs.
- Disadvantages: expensive; may increase debt; local people may not benefit and may even be displaced; can harm the environment.
Bottom-up development involves small-scale projects led by communities, often with non-governmental organisations (NGOs) — wells, solar panels, training, microfinance loans and health education.
- Advantages: meets local needs directly; uses appropriate, affordable technology; empowers communities; sustainable.
- Disadvantages: small scale, so each project helps relatively few people; relies on continued funding and support.
Trade, aid, investment and TNCs
Fair trade guarantees producers a minimum price and a premium for community projects.
Aid can be short-term emergency aid after disasters or long-term development aid for health, education and infrastructure. It can be bilateral (country to country) or multilateral (through organisations such as the UN). Aid can be very effective, but it may be tied (requiring the money to be spent on the donor's goods), may not reach those most in need, and can create dependency.
TNCs invest in factories, offices and services in developing and emerging countries. They create jobs, bring new technology and skills, and pay taxes. However, wages may be low, working conditions poor, profits often go back to the TNC's home country, and environmental regulations may be weaker.
India: an emerging country
India has one of the world's largest and fastest-growing economies and a population of more than 1.4 billion. Its development has been driven by:
- economic reforms from the early 1990s that opened the economy to foreign investment and trade;
- growth in services, especially IT and business services centred in cities such as Bengaluru, Mumbai and Hyderabad;
- manufacturing of cars, pharmaceuticals and textiles;
- a large, young and increasingly educated workforce, many of whom speak English;
- TNC investment and remittances from Indians working abroad.
Impacts and challenges:
- Rising incomes, a growing middle class and improved life expectancy and literacy.
- Large regional inequality: states such as Maharashtra and Karnataka are much richer than rural states in the north and east.
- Many people still work in farming and the informal economy, and poverty remains high in rural areas.
- Rapid urbanisation has created informal settlements in cities.
- Environmental problems, including severe air pollution in cities and pressure on water supplies.
Both top-down projects (such as large dams and new highways) and bottom-up initiatives (such as rural sanitation, education and microfinance schemes) are used to spread the benefits of growth.
TNCs in India: benefits and costs
India has attracted many transnational corporations, particularly in IT services, business process outsourcing such as call centres, car manufacturing and pharmaceuticals. Indian companies have also become TNCs themselves, operating around the world.
Benefits: jobs for educated young people, often at higher wages than other local employment; training and new skills; investment in infrastructure; tax revenue for government; and a growing middle class with more spending power.
Costs: many jobs are concentrated in a few large cities, widening regional inequality; some workers face long hours and job insecurity; profits may flow back to the TNC's home country; and rapid industrial growth can increase pollution and pressure on land and water.
Reducing the development gap: a summary of strategies
| Strategy | How it helps | Limitations |
|---|---|---|
| Investment and industrialisation | Creates jobs and income | Benefits may be uneven |
| Fair trade | Fairer prices for producers | Small share of total trade |
| Debt relief | Frees money for health and education | Conditions may be attached |
| Aid | Funds projects and emergencies | May be tied or create dependency |
| Microfinance | Small loans help people start businesses | Small scale; repayment pressure |
| Intermediate technology | Affordable, locally maintained solutions | Limited scale |
No single strategy closes the gap; most countries that have developed rapidly have combined investment, education and good governance.
Worked examples
Example 1: Measuring development
Explain why HDI is a better measure of development than GNI per capita. (3 marks)
Answer: HDI combines several indicators — life expectancy, education and income (1) — so it shows quality of life as well as wealth (1). GNI per capita is an average that hides inequality and says nothing about health or education (1).
Example 2: Causes of uneven development
Explain how trade can cause uneven development. (3 marks)
Answer: Many developing countries export raw materials, which have low and unstable prices (1), while importing expensive manufactured goods (1). This means they earn less from trade, leaving less money for development (1).
Example 3: Evaluating approaches
Assess whether bottom-up projects are more effective than top-down projects.
Answer: Bottom-up projects meet local needs, use affordable technology and involve communities, so they are often sustainable and benefit the poorest directly. However, they are small in scale. Top-down projects can transform national infrastructure and create many jobs but are expensive, can increase debt and may not benefit local people. The most effective strategies often combine both.
Common mistakes and how to avoid them
- Using only one measure of development.
- Assuming all aid is good. Discuss tied aid and dependency.
- Ignoring inequality within countries such as India.
- Confusing top-down and bottom-up approaches.
- Describing data without interpreting it. Explain what the figures show.
Exam technique for "Global Development"
- When interpreting data, quote figures and compare countries.
- Use the categories physical, historical, economic and political when explaining causes.
- In case study answers, refer to specific places and features of India.
- In evaluations, give advantages and disadvantages and finish with a judgement.
