Unit 2: Living in Our World — Theme C: Contrasts in World Development
Chapter: The Development Gap
Welcome to your study notes for The Development Gap! This topic is a core part of Unit 2: Living in Our World (Paper Code: GGY21) in your CCEA GCSE Geography course. In this unit, we explore how wealth, health, and opportunities are shared across our planet, why huge differences exist between nations, and what can be done to build a fairer world.
Don't worry if some of the terms seem a little technical at first. We will break down every concept step-by-step with real-world examples, memory tips, and examiner advice so you can feel completely confident in your exam!
1. Key Terminology and Classifications
Before we can measure differences between nations, we need to understand the basic vocabulary that geographers use.
Core Definitions
• Development: The process of positive change and growth over time that improves the quality of life and standard of living for people in a country.
• The Development Gap: The widening economic and social difference or inequality between the world's richest countries and poorest countries.
Country Classifications
CCEA examiners expect you to recognise three key groupings of countries:
• MEDC (More Economically Developed Country): Highly industrialised nations with high average incomes, advanced infrastructure, and a high standard of living. Examples include the UK, Japan, and the USA.
• LEDC (Less Economically Developed Country): Countries with lower levels of industrialisation, lower income per person, and lower human development. Examples include Mali, Bangladesh, and Kenya.
• BRICS: An acronym representing five rapidly emerging, major world economies that are growing fast in wealth and global influence:
B — Brazil
R — Russia
I — India
C — China
S — South Africa
Memory Trick: Think of BRICS as the strong building "bricks" of the newly emerging global economy!
Key Takeaway: Development is not just about having more money; it is about improving everyday human lives. The Development Gap is the uneven divide between wealthy MEDCs and poorer LEDCs.
2. Measuring Development: Indicators and Indices
How do we know how developed a country is? Geographers use specific measurements called indicators. Examiners test whether you can clearly separate economic indicators from social indicators.
A. Economic Indicators (Money & Jobs)
• Gross Domestic Product (GDP) / Gross National Income (GNI) per capita: The total economic value of goods and services produced by a country in one year, divided by its total population. It is usually expressed in US Dollars (\$). It gives an average income per person.
• Percentage of Population Employed in Primary Activities: The proportion of people working in farming, fishing, forestry, or mining. LEDCs typically have a high percentage of workers in the primary sector, whereas MEDCs have very few workers in primary jobs and most in tertiary (services) or quaternary (research/tech) sectors.
B. Social Indicators (Health, Education & Wellbeing)
• Life Expectancy at Birth: The average number of years a newborn baby is expected to live based on current healthcare and mortality conditions.
• Infant Mortality Rate: The number of babies who die before their first birthday per \(1,000\) live births in a year.
• Adult Literacy Rate: The percentage of people aged \(15\) and older who can read and write a simple statement.
• Access to Safe Water / Internet: The percentage of the population with reliable access to clean, safe drinking water or modern digital infrastructure.
C. Composite Measure: The Human Development Index (HDI)
A single indicator (like income alone) can be misleading. A country might have huge oil wealth, but its ordinary citizens might still lack good schools and hospitals. To solve this, the United Nations created the Human Development Index (HDI).
The 3 Pillars of HDI:
1. Health: Measured by Life Expectancy at birth.
2. Education: Measured by mean (average) and expected years of schooling.
3. Standard of Living: Measured by GNI per capita.
How HDI is Scored:
• HDI uses a scale from \(0\) to \(1.0\).
• Scores close to \(1.0\) (e.g., \(0.900\) or higher) show very high development (e.g., UK, Norway).
• Scores below \(0.550\) show low development (e.g., Mali, Niger).
Why is HDI superior to single indicators?
In exam questions, always explain that HDI gives a balanced, broader picture of human progress. It prevents economic distortions caused by small, ultra-rich elites and reflects real quality of life, including healthcare and schooling.
Common Examiner Trap to Avoid: Never label HDI or Literacy Rate as an "economic" indicator. HDI is a composite index, and literacy is a social indicator!
3. Factors Influencing the Development Gap
Why are some countries rich while others remain poor? The development gap is caused by a combination of physical and economic/historical factors.
A. Physical and Environmental Factors
• Landlocked Status: Countries without a coastline (such as Chad or Bolivia) find international trade difficult and expensive because all goods must travel through neighbouring countries to reach sea ports.
• Hostile Climate & Drought: Frequent droughts or extreme temperatures make farming unreliable, leading to food shortages, malnutrition, and reduced agricultural income.
• Natural Hazards: Frequent tropical cyclones, floods, or earthquakes destroy roads, homes, and schools, forcing governments to spend scarce funds on rebuilding rather than long-term development.
• Poor Soil Fertility: Thin, nutrient-poor soils limit crop yields, keeping communities trapped in subsistence farming.
B. Economic and Historical Factors
• Colonial Legacy: Many LEDCs were colonised in the past. Rulers extracted raw materials (such as timber, minerals, and cocoa) without building local factories, infrastructure, or education systems.
• Reliance on Primary Commodities: LEDCs often rely on exporting raw agricultural goods or minerals. These have low added value and suffer from fluctuating global market prices.
• Unfavourable Terms of Trade: LEDCs export cheap raw materials but must import expensive manufactured goods and machinery from MEDCs.
• Heavy National Debt: Borrowing large sums of money means poorer nations spend millions each year paying back interest to international banks rather than investing in clean water, hospitals, and schools.
Key Takeaway: The development gap is not an accident; it is the result of difficult physical environments combined with historical trade inequalities and debt burdens.
4. Strategies to Reduce the Development Gap
To close the gap, global organisations, charities, and governments use several key strategies.
1. The UN Sustainable Development Goals (SDGs)
In 2015, the United Nations launched the 2030 Agenda for Sustainable Development. This is a shared blueprint consisting of 17 global goals designed to end extreme poverty, reduce inequalities, tackle climate change, and ensure peace and prosperity for all by 2030.
2. Fair Trade
What is it? An ethical trading system designed to support disadvantaged farmers and producers in LEDCs (often producing cocoa, coffee, tea, or bananas).
How does Fair Trade work?
• Guaranteed Minimum Fair Price: Farmers receive a guaranteed price for their crops even if global market prices crash, protecting them from poverty.
• Social Premium: An extra sum of money paid on top of the selling price. The farming cooperative democratically decides how to invest this money in community projects such as building clean water wells, health clinics, or primary schools.
• Decent Working Conditions: Prohibits forced labour and child labour, while enforcing safe working environments and sustainable farming methods.
Exam Note: Fair Trade is not charity or a handout; it is an equal, commercial trading partnership!
3. Appropriate Technology (Intermediate Technology)
What is it? Technology that is suited to the wealth, skills, resources, and environmental conditions of local people in an LEDC.
Key Characteristics of Appropriate Technology:
• Simple to build and operate using local knowledge.
• Cheap to maintain and repair using locally sourced, readily available spare parts.
• Does not rely on expensive imported fuel, high-tech computer systems, or foreign experts.
• Environmentally friendly and sustainable over the long term.
Examples in LEDCs:
• Gravity-fed water piping systems that supply mountain villages with clean water without needing expensive diesel pumps.
• Sand dams in semi-arid regions that harvest and store clean rainwater underground, preventing evaporation.
• Micro-hydro power schemes that generate electricity for rural clinics using local streams.
4. Globalisation and Transnational Corporations (TNCs)
Globalisation: The growing integration and interdependence of the world's economies, cultures, and populations.
Transnational Corporations (TNCs): Huge companies that operate, produce, and sell goods in more than one country (e.g., Nike, Coca-Cola, Apple).
In your CCEA exam, you must provide a balanced evaluation of TNCs investing in LEDCs:
Advantages of TNCs in LEDCs:
• Job Creation: Direct employment for local people, providing regular wages.
• Skills Training: Local workers learn modern manufacturing, engineering, and management skills.
• Infrastructure Development: TNCs often help improve local roads, ports, electricity grids, and communication links.
• Multiplier Effect: Local businesses (suppliers, food vendors, transport) grow by serving the TNC and its workers.
Disadvantages of TNCs in LEDCs:
• Profit Repatriation: The vast majority of profits are sent back to the TNC's home country (an MEDC) rather than staying in the local LEDC economy.
• Exploitation of Labour: Pay can be very low compared to MEDC wages, with long working hours and poor safety standards.
• Footloose Nature: TNCs can easily close factories and move to another country if labour costs become cheaper elsewhere, leaving sudden mass unemployment.
• Environmental Damage: Less strict environmental laws in LEDCs may lead to chemical dumping, air pollution, and deforestation.
5. Quick Summary & Exam Technique Checklist
Quick Review Box:
• Development = positive change improving living standards.
• LEDC = low income/development; MEDC = high income/development; BRICS = Brazil, Russia, India, China, South Africa.
• HDI = Life Expectancy + Education + GNI per capita (scored \(0\) to \(1.0\)).
• Appropriate Technology = Cheap, local, easy-to-repair technology that locals can run independently.
• Fair Trade = Guaranteed minimum price + Social Premium for community projects.
Top Examiner Tips for Question 3 (Theme C):
1. Always state both sides: When asked about TNCs or globalisation, give at least two clear benefits and two clear problems to access the highest mark band.
2. Be specific with HDI: State all three components (health, education, income) and explain that it eliminates the skewing effect of wealth alone.
3. Use precise vocabulary: Use terms like social premium, profit repatriation, landlocked, and appropriate technology to demonstrate top-tier geographical understanding.
