Cambridge International AS & A Level Geography (9696): Topic 11 – Production, location and change – Study Guide

This guide covers Topic 11, Production, location and change, from the Cambridge International AS & A Level Geography (9696) syllabus for examination in 2025 and 2026. It teaches every point in sections 11.1 to 11.4. The topic is one of four Advanced Human Geography Options assessed in Paper 4 (1 hour 30 minutes, 60 marks, 25% of the A Level). You must study two of the four options, and for each option you answer one structured question (10 marks) and one essay from a choice of two (20 marks each).

Use it with the revision notes, the practice questions, the Cambridge A Level Geography hub and the Geography checklist. The food-security material in our Core Human Geography study guide is useful background.

11.1 Factors affecting farm land use and practices

Farm decisions reflect four groups of factors.

• Physical: climate, relief, soils, water supply.
• Social: land tenure, inheritance, farm size, education, diet and culture.
• Economic: demand, prices, input costs, credit, distance from markets.
• Political: subsidies, guaranteed prices, land reform, trade rules.

The syllabus names four of these for special attention.

Irrigation removes the water limit. It allows a second or third crop each year, higher-value crops and reliable yields. Flood irrigation is cheap but wasteful; drip is costly but efficient. Risks include waterlogging, salinisation and falling water tables.

Land tenure is the way land is owned or occupied. Owner-occupiers can invest for the long term; tenants and sharecroppers (who pay rent as a share of the crop) have less reason to improve land. Communal tenure gives shared access, often to grazing. Inheritance that divides land among heirs causes fragmentation: many small, scattered plots that are hard to mechanise. Land consolidation joins them up.

Demand and distance from markets. Von Thünen’s model (1826) predicts rings of land use around a single market town. Perishable or bulky products that cost a lot to move per hectare (market gardening, dairying) locate close. Land uses with low output per hectare (grain, ranching) locate further out. The idea is locational rent: income per hectare minus production and transport costs.

Evaluation: the model assumes one market, flat uniform land, one transport mode and profit-maximising farmers. Refrigeration and air freight have shrunk the friction of distance: Kenyan cut flowers are flown to Europe. It still explains dairying and vegetables near large cities.

Agricultural technology includes mechanisation, high-yielding varieties (HYVs), fertilisers, pesticides, GM crops and GPS-guided precision farming. It raises output but needs capital, so it can widen the gap between large and small farms.

11.1 Agricultural systems: one arable, one pastoral

A system has inputs (physical: sun, rain, soil; human: labour, seed, fertiliser, capital), throughputs (sowing, harvesting, milking), subsystems (linked parts, such as a crop subsystem feeding a livestock subsystem) and outputs (crops, livestock products, waste, income).

Arable example: wheat farming on the Canadian Prairies. Inputs: deep, fertile chernozem soils, a short but warm growing season, large farms, heavy machinery and fertiliser. Throughputs: mechanised sowing in spring, spraying, combine harvesting in late summer. A storage and marketing subsystem moves grain to elevators and by rail to ports such as Vancouver and Thunder Bay. Outputs: wheat and canola, straw, income. This is a commercial, extensive system.

Pastoral example: dairy farming in New Zealand’s Waikato region. Inputs: mild, wet climate, grass that grows for most of the year, cows, fertiliser, labour, milking sheds. Throughputs: rotational grazing, milking, herd breeding. A grass subsystem feeds the herd subsystem. Outputs: milk sent to processors such as Fonterra (a farmer-owned co-operative), calves, manure and nitrate run-off. This is a commercial, intensive pastoral system.

11.1 Intensive and extensive production and productivity

Intensive farming uses high inputs of labour and/or capital per hectare and gets high output per hectare (market gardening, wet rice). Extensive farming uses low inputs per hectare over large areas (ranching, nomadic herding, large grain farms).

Agricultural productivity is output per unit of input. Measure it carefully:

• per hectare (land productivity), where intensive farms score highest;
• per worker (labour productivity), where mechanised extensive farms often score highest.

A smallholder rice farm can have high yield per hectare but low output per worker. A Prairie wheat farm is the reverse. Always say which measure you mean.

11.1 Issues in intensification and extension of cultivation

Intensification raises output from the same land. Issues: nutrient loss, salinisation, groundwater depletion, eutrophication from fertiliser run-off, biodiversity loss and debt among farmers who borrow for inputs.

Extension of cultivation brings new land into farming. Issues: deforestation and carbon release (for example the soy and cattle frontier in Brazil’s Amazon and Cerrado), farming of marginal semi-arid land that is at risk of degradation, conflict with pastoralists or indigenous groups, and habitat loss.

Evaluation: intensification can spare land from clearance, but only if gains are not simply used to expand. Extension can be controlled. The Amazon Soy Moratorium (2006), agreed by traders, cut the direct link between soy and new clearance in the Amazon, but critics argue clearance moved to the Cerrado and to cattle.

11.2 Case study: managing agricultural change in India

The syllabus requires one country, at the local scale (farm or producer) and the national scale. India is used here.

The need for change. In the mid-1960s India faced food shortages and relied on food aid. The Green Revolution, introduced in Punjab in the late 1960s, combined HYV wheat and rice, fertiliser, pesticides, credit and irrigation. M. S. Swaminathan is widely called its main architect. Gains were largest in Punjab, Haryana and western Uttar Pradesh. Minimum support prices (MSP) date from the mid-1960s, and the Food Corporation of India buys grain for the public distribution system.

Local scale: a Punjab smallholder. A typical family grows rice in the monsoon season and wheat in winter. Tubewells pump groundwater, and Punjab has given farmers free electricity for pumps. Difficulties:

• water tables are falling because rice needs heavy irrigation;
• only weeks separate the rice harvest from wheat sowing, so many farmers burn stubble, adding to Delhi’s air pollution;
• small holdings and rising input costs push some farmers into debt.

Responses at this scale include a 2009 Punjab law that delays rice transplanting until a notified date in June, so the crop uses more monsoon rain; machines such as the Happy Seeder, which sow wheat through the stubble; and a 2022 offer to buy maize and bajra (millet) at MSP, to draw farmers away from rice.

National scale. Most Indian holdings are under 2 hectares. Policies include MSP and procurement, input subsidies, the Soil Health Card scheme (2015) and PM-KISAN (2019), which pays landholding farm families Rs 6,000 a year in three instalments. In September 2020 Parliament passed three farm laws to open up private trade and contract farming. Farmers, led by those from Punjab, Haryana and western Uttar Pradesh, protested for over a year and demanded a legal guarantee of MSP. The government announced repeal on 19 November 2021.

Evaluation.

• Success: India moved from food shortage to large grain surpluses, and output per hectare rose sharply.
• Limits: benefits went mainly to irrigated areas and larger farmers. MSP procurement concentrates on wheat and rice, which locks Punjab into a water-hungry rotation. PM-KISAN excludes tenant farmers who do not own land.
• Difficulty of management: the 2020 reforms show that national change fails without farmers’ support, and local fixes (delayed transplanting) can shorten the window before wheat and encourage burning.

Worked paragraph (Evaluate): “India’s Green Revolution solved the national problem of the 1960s but created new local problems. Nationally, HYVs, fertiliser and guaranteed prices made India a grain-surplus country. On Punjab farms, however, the rice-wheat rotation depends on pumped groundwater, so water tables are falling. A solution designed for food quantity ignored sustainability. Delayed transplanting and MSP offers for maize try to correct this, but while MSP still favours rice and wheat, success is likely to be partial.”

11.3 Factors in the location of manufacturing and related services

• Land: cost, flat sites, room to expand.
• Labour: cost and skills; assembly seeks low wages, research seeks skills.
• Capital: investment from banks, governments or transnational corporations (TNCs).
• Markets: bulk-gaining or perishable goods locate near consumers.
• Materials: bulk-reducing industries (ore smelting) locate near raw materials.
• Technology: containers and the internet free many firms from fixed locations.
• Economies of scale: unit costs fall as output rises; diseconomies (congestion, high rents) push firms out.
• Inertia: firms stay after the original advantage has gone.
• Transport: ports and motorway junctions attract firms.
• Government policies: grants, tax breaks, zones, tariffs.

Alfred Weber’s least-cost theory (1909) explains location by minimising transport and labour costs. Evaluation: it suits past heavy industry better than footloose high-tech or service firms, which weigh skills and incentives more. “Related service industry” means services linked to manufacturing, such as logistics and maintenance.

11.3 Agglomeration, linkages, estates and EPZs

Industrial agglomeration is the clustering of firms in one area. Firms gain external economies: a skilled labour pool, shared suppliers, specialist services and shared infrastructure.

Functional linkages are the connections between firms:

• backward linkages to suppliers;
• forward linkages to customers;
• horizontal (lateral) linkages between firms making parts for the same final product;
• service linkages to transport, finance and repair firms.

Example of agglomeration: Sialkot in Pakistan is known as a world centre of surgical-instrument manufacture, and also makes footballs, other sports goods and leather goods. Thousands of small firms share suppliers and skills, and local business funded a dry port and an international airport. Evaluation: the cluster shows how linkages and inertia hold an industry in place for over a century, but it depends on low-cost labour and export demand.

An industrial estate is a planned area with serviced plots, roads, power and water, built for several firms. It cuts start-up costs and separates industry from housing.

An export processing zone (EPZ) is a fenced area where firms import materials duty-free, process them and export the product, often with tax holidays. Example: the Chittagong EPZ in Bangladesh opened in 1983 and is run by the Bangladesh Export Processing Zones Authority (BEPZA). New factories have been offered a five-year tax holiday, and ordinary trade unions have been banned inside the zones. Evaluation: EPZs bring jobs, foreign investment and export earnings, but linkages to local firms can be weak, profits may leave the country and labour rights are often restricted.

11.3 The informal sector

The informal sector is economic activity that is not registered, regulated or taxed by the state.

• Causes: urban growth faster than formal jobs; lack of skills or capital; costly regulation.
• Characteristics: small scale, family labour, low capital, easy entry, irregular income, no legal protection.
• Location: markets, transport hubs, roadsides and homes in informal settlements, close to customers.
• Impact: positive (jobs, cheap goods, skills, recycling, subcontracting for formal firms); negative (low, unstable pay, unsafe work, lost tax revenue).

Example: in Kenya informal artisans are called jua kali (“hot sun” in Swahili), as many first worked outdoors. Nairobi’s Kamukunji area has thousands of small jua kali enterprises, with their own association. Evaluation: governments now often support the sector (sheds, training, microcredit), but formalisation can raise costs and push the poorest out.

11.4 Case study: Malaysia’s industrial policy

Character, location and organisation over time.

1. Import substitution (late 1950s and 1960s): tax relief and tariffs encouraged firms to make goods for the home market.
2. Export orientation (1970s): the Free Trade Zones Act (1971) and the Bayan Lepas Free Industrial Zone in Penang (1972) drew electronics TNCs such as Intel, AMD and Hewlett-Packard. The New Economic Policy (1971) aimed to raise the Malay (Bumiputera) share of the economy.
3. Heavy industry (1980s): HICOM (1980) and the national car company Proton (1983), whose first car, the Saga, launched in 1985 with Mitsubishi as partner.
4. Master plans and knowledge industry: Three Industrial Master Plans followed, the third covering 2006-2020. The Multimedia Super Corridor (1996) stretched from Kuala Lumpur to the new airport. Proton opened a plant at Tanjung Malim in 2003. The New Industrial Master Plan 2030 came next.

Character changed from processing rubber and tin to electronics, cars and semiconductors; electrical and electronics products now make up around 40% of exports. Location concentrated in Penang, the Klang Valley and Johor. Organisation mixed foreign TNC branch plants, state-led firms and local suppliers.

Issues and evaluation.

• Success: Malaysia became a major electronics exporter with a deep supplier cluster in Penang.
• Proton: despite protection, its market share fell from 74% (1993) to 32% (2006), and in 2017 China’s Geely bought a 49.9% stake. Protection created a national brand but not lasting competitiveness.
• Dependence: much work is assembly and testing for foreign firms, and many factories rely on migrant workers, which may slow the move to higher-value work.
• Regional imbalance: Sabah, Sarawak and the east coast gained less than the west coast.

Worked paragraph (How far): “Malaysia’s industrial policy changed the location of manufacturing more than its ownership. Free trade zones concentrated electronics in Penang and the Klang Valley, while the east coast gained little. Yet much output is controlled by foreign TNCs, and even state-backed Proton passed into part-Chinese ownership in 2017. Policy created industrial regions but only partly created Malaysian-owned industry.”

Common errors

• Treating productivity as one figure: say per hectare or per worker.
• Describing a system as a list of crops, with no inputs, throughputs, subsystems or outputs.
• Giving the India case at national scale only; 11.2 requires the farm scale too.
• Calling every special zone an EPZ: an EPZ means duty-free processing for export.
• Writing about the informal sector as wholly negative; the syllabus asks for impact, which includes benefits.
• Describing Malaysia’s policies without evaluating them.
