Introduction
Economic geography asks where production occurs and why. Agriculture depends on physical conditions and markets; industry depends on inputs, transport, labour, energy, capital and agglomeration; resource use raises the question of sustainability.
The easiest preparation method is “location factors.” For every activity ask what attracts it to a place and what may push it away.
Source-Aligned Core Concepts
- Factors affecting agriculture: Climate, soils, water, relief, farm size, labour, technology, capital, transport, market access, policy and land tenure influence agriculture.
- Subsistence agriculture and population: Subsistence farming mainly produces for household/local use and may be labour intensive. Population pressure can encourage intensification, fragmentation or migration, depending on local conditions.
- Commercial agriculture and markets: Commercial farming responds strongly to prices, transport, processing, technology and consumer demand. It can be highly specialized and capital intensive.
- Sustainable agriculture: Sustainable agriculture aims to maintain productivity while protecting soil, water, biodiversity and long-term viability. Practices vary by environment; there is no single universal technique.
- Types and distribution of agriculture: Study broad systems—pastoral, shifting cultivation, intensive subsistence, plantation, mixed farming, commercial grain, livestock/ranching and Mediterranean-type agriculture—through climate, market and settlement context.
- Industrial location: Raw materials, energy, labour, market, transport, land, capital, government policy, agglomeration and technology affect industrial location. Their relative importance changes by industry and over time.
- Industrial Revolution: Industrialization shifted production toward mechanized factory systems, transformed transport and urbanization, and created new spatial concentrations of industry.
- Industrial theories: Classical location theory, including Weber’s least-cost approach, highlights transport, labour and agglomeration. Later approaches add markets, behavioural decisions, flexible production and global networks.
- Industrial distribution and estates: Industries cluster where infrastructure, suppliers, labour and markets create advantages. Industrial estates or zones concentrate infrastructure and planned industrial land.
- Renewable resources: Renewable resources can replenish on human timescales if use does not exceed regeneration. Examples include solar, wind and sustainably managed biological resources.
- Recycling and sustainability: Recycling reduces demand for virgin materials and waste, but it also requires energy, collection and viable processing. Sustainable resource management emphasizes reduction, efficiency, reuse, recycling and responsible extraction.
Expanded Master Explanation
The following sections develop the compressed source notes into the academic depth needed for first-time understanding and analytical answer writing.
Agricultural systems and the factors that shape them
- Physical controls: Climate, soil, water, relief and length of growing season influence what can be produced. Technology can reduce some constraints but not remove ecological limits entirely.
- Economic controls: Market access, prices, credit, land tenure, labour, transport and state policy affect crop choice and intensity.
- Subsistence and commercial agriculture: Subsistence systems primarily support the producing household, while commercial systems are strongly oriented to markets. Many real farms combine both, so the categories form a continuum.
- Intensive and extensive systems: Intensive agriculture uses more labour, capital or other inputs per unit of land; extensive systems use larger areas with lower input density. Productivity should be distinguished from total output.
Agricultural location and Von Thünen
Von Thünen's model explains agricultural land use around a market under simplified assumptions: a flat uniform plain, one central market, equal soil quality and transport costs rising with distance. High-value or perishable products locate near the market; land-intensive or low-transport-sensitive activities locate farther away.
The model remains useful because it teaches how transport cost and land rent influence location, but modern refrigeration, highways, global trade, multiple markets, state policy and uneven environments mean actual patterns rarely form perfect rings.
Agricultural change and food security
- Green Revolution: High-yield crop varieties, irrigation, fertilizer and associated inputs increased cereal production in many regions. Benefits were significant, but access to land, water and credit was unequal, and intensive input use created environmental costs in some places.
- Mechanization: Machinery can raise labour productivity and timeliness, but effects on employment depend on farm structure and alternative jobs.
- Irrigation: Irrigation reduces rainfall uncertainty and enables multiple cropping, but poor drainage can cause salinization or waterlogging. Sustainable irrigation therefore requires water accounting and soil management.
- Food security: Food security involves availability, access, utilization and stability. A country can produce sufficient food nationally while households remain food insecure because of poverty, prices or distribution.
Industrial location
- Raw materials: Weight-losing industries may locate near bulky inputs, while industries using widely available inputs may be more market-oriented.
- Energy: Historically, coal and hydropower strongly shaped industrial regions. Modern electricity grids reduce but do not eliminate energy considerations, especially for energy-intensive industries.
- Labour: Cost, skill, productivity and labour relations influence location. High-skill sectors often cluster where universities, suppliers and specialized labour markets already exist.
- Market: Firms may locate near consumers when products are perishable, costly to transport or require rapid delivery and service.
- Transport and agglomeration: Ports, highways and logistics nodes lower movement costs. Clustering can create shared suppliers, labour pools and knowledge spillovers, but congestion and high land costs can eventually encourage decentralization.
Weber and later industrial-location thinking
Alfred Weber's least-cost theory emphasizes transport cost, labour cost and agglomeration. It is valuable for showing why firms compare input and market locations. Its limits are equally important: modern firms consider taxes, regulation, skills, innovation networks, global value chains, political stability and digital connectivity as well as transport cost.
Location decisions should therefore be treated as multi-factor choices under uncertainty rather than as outcomes of one formula.
Natural resources and energy
- Renewable resources: Resources such as forests, fisheries and groundwater can renew if use does not exceed regenerative capacity. Renewable does not mean unlimited.
- Non-renewable resources: Minerals and fossil fuels form over geological time and are depleted by extraction. Economic reserves depend on price, technology and accessibility as well as physical occurrence.
- Energy transition: Energy systems are shifting toward larger shares of solar, wind and other low-carbon sources in many countries, but grids, storage, finance, land and existing infrastructure shape the pace.
- Resource curse debate: Resource wealth can finance development, yet some resource-dependent economies experience volatility, corruption or weak diversification. The outcome depends strongly on institutions and policy rather than resources having one automatic political effect.

How to Prepare This Topic
- Create two location-factor wheels: one for agriculture and one for industry.
- Prepare a simple Weber triangle/least-cost sketch if comfortable, but explain the assumptions.
- Make a table of farming systems and their climatic/market settings.
- Use sustainability as a balance among productivity, environment and long-term resource security.
Common Confusion / Mistake
| Avoid this error Do not assume modern industry always locates near raw materials. Transport, knowledge, services, labour and markets can be more important for many contemporary industries. |

How to Build an Examination Answer
Organize into agriculture, industry and resources. For each, emphasize location factors, types/distribution, change over time and sustainability.
