Key Terminology (Grade 12 NSC Matric Geography): Revision Notes
Key Terminology
Understanding the correct terminology is essential for success in economic geography. These key concepts form the foundation for analysing South Africa's economic activities, trade relationships, and development patterns. Mastering these definitions will help you tackle exam questions with confidence and demonstrate your understanding of economic geographical processes.
These terminology definitions are fundamental building blocks that appear frequently in economic geography examinations. Take time to understand not just the definitions, but how these concepts interconnect and influence each other in South Africa's economic landscape.
Economic activity classifications
Economic activities are organised into four main categories, each representing different levels of production and processing. This classification system helps us understand how economies develop and change over time.
Primary activities involve extracting natural resources directly from the earth. These include farming operations like growing crops and raising livestock, mining activities such as coal and gold extraction, forestry work, and fishing. South Africa's economy has historically been built on strong primary sector activities, particularly mining.
Secondary activities focus on processing raw materials and manufacturing finished goods. This sector includes factories that process agricultural products, manufacturing plants that produce consumer goods, and industries that transform mined materials into useful products. These activities add value to primary sector outputs.
Tertiary activities provide services to people and businesses. This broad category includes banking and financial services, retail trade, transportation networks, tourism, education, and healthcare. The tertiary sector has grown significantly in South Africa's modern economy.
Quaternary activities represent the most advanced economic activities, dealing with information processing, research and development, and knowledge-based services. This includes computer programming, scientific research, financial planning, and high-tech industries.
Economic Development Progression
Countries typically develop through these sectors in sequence: Primary → Secondary → Tertiary → Quaternary. South Africa is transitioning from a primary sector-dominated economy to one with stronger secondary and tertiary sectors.
Trade and economic indicators
International trade terminology helps explain how countries interact economically with the rest of the world. Understanding these concepts is crucial for analysing South Africa's position in the global economy.
The balance of payment represents a country's complete financial statement, showing all economic transactions with other nations. This includes trade in goods and services, investment flows, and financial transfers.
The balance of trade specifically measures the difference between exports and imports. When exports exceed imports, the country has a favourable trade balance, which brings foreign currency into the economy. Exports are goods and services sold to other countries, while imports are goods and services purchased from foreign nations.
Gross Domestic Product (GDP) measures the total value of all goods and services produced within a country's borders during one year, regardless of who produces them. Gross National Product (GNP) measures the total value of goods and services produced by a country's permanent citizens, whether they work at home or abroad.
Key Distinction: GDP vs GNP
- GDP focuses on location (within the country's borders)
- GNP focuses on citizenship (by the country's citizens anywhere in the world)
This distinction affects how we measure a country's true economic performance and citizen prosperity.
Foreign exchange refers to the money that other countries pay to South Africa for goods and services, typically in currencies like dollars and pounds. This foreign currency is essential for purchasing imports and maintaining international economic relationships.
Worked Example: Trade Balance Calculation
If South Africa exports R500 billion worth of goods and imports R450 billion worth of goods:
- Trade Balance = Exports - Imports
- Trade Balance = R500 billion - R450 billion = R50 billion
- This represents a favourable trade balance of R50 billion surplus
Industrial location and development concepts
Industrial geography involves understanding where industries locate and why. Centralisation describes the movement of industries into core urban areas, while decentralisation involves moving economic activities away from overcrowded central areas to spread development more evenly.
Footloose industries can locate anywhere without being significantly affected by factors like access to raw materials or transportation costs. Examples include diamond processing and computer chip manufacturing, which deal with high-value, low-weight products.
Bridge industries are strategically located between raw material sources and customers. Oil refineries exemplify this concept, as they process crude oil from sources and deliver refined products to consumers.
Bridge industries serve as crucial links in the supply chain, adding value by transforming raw materials closer to either their source or their final market, depending on what is more economically efficient.
Industrial Development Zones (IDZ) are specially designated areas aimed at promoting economic growth and attracting new investment. These zones are used by developing countries like South Africa to create jobs, boost exports, and attract foreign investment through various incentives.
Worker classifications and sectors
The labour market is classified based on skill levels and training requirements. Skilled workers possess specialised knowledge and abilities, usually obtained through formal training or education. Semi-skilled workers perform routine tasks and may have some specialised training, but not to the same extent as skilled workers. Unskilled workers perform simple duties requiring no specific skills, training, or previous experience, often involving physical labour.
The economy is also divided into formal and informal sectors. The formal sector consists of registered businesses licensed to sell goods or provide services, operating within official regulatory frameworks. The informal sector includes small, unregistered businesses like street vendors, casual employment, spaza shops, and hawkers who operate without formal licenses.
Formal vs Informal Sector Impact
The size of the informal sector often indicates economic challenges. A large informal sector can suggest:
- Limited formal job opportunities
- High unemployment rates
- Need for skills development programmes
- Challenges in tax collection and economic planning
Development strategies and programmes
Spatial Development Initiatives (SDI) are programmes designed to improve infrastructure and attract business investment to rural areas that have been neglected and underdeveloped. These initiatives aim to spread economic development more evenly across the country.
Globalisation describes how economic, social, political, and cultural activities of countries worldwide are becoming increasingly interconnected. This process affects how South Africa trades, attracts investment, and participates in the global economy.
Globalisation has both positive and negative effects on developing countries like South Africa. While it opens new markets and attracts investment, it also creates competition for local industries and can increase economic dependence on global markets.
Food security concepts
Food security exists when all people have enough food to meet their needs for healthy and productive living. Food insecurity occurs when not all people have sufficient access to nutritious food, which can lead to malnutrition and reduced productivity.
Food security is not just about food production—it's about access, availability, utilisation, and stability. South Africa produces enough food overall, but distribution and access remain significant challenges for many communities.
Infrastructure and development
Infrastructure encompasses the transport networks (roads, railways) and services (electricity, telecommunications, water, and sewerage systems) that support economic activity. Strong infrastructure is essential for economic development and connecting different regions of the country.
Trading blocs are groups of countries that establish common markets or trade agreements to facilitate easier and cheaper trade between member nations.
South Africa participates in several trading blocs, including the Southern African Development Community (SADC) and the African Continental Free Trade Area (AfCFTA), which help reduce trade barriers and promote regional economic integration.
Key Points to Remember:
- Economic activities progress from primary (extraction) → secondary (processing) → tertiary (services) → quaternary (information/research)
- GDP measures production within borders, GNP measures production by citizens anywhere
- Formal sector = registered and licensed; Informal sector = unregistered small businesses
- Footloose industries can locate anywhere; Bridge industries locate between sources and customers
- Food security means everyone has enough nutritious food; Infrastructure supports all economic activities
- Trade balance = Exports - Imports (positive = favourable, negative = unfavourable)
- Globalisation increases interconnection but creates both opportunities and challenges
