Cambridge IGCSE Pakistan Studies: Agricultural Development (0448)

Agricultural development is Section 4 of Paper 2 in Cambridge IGCSE Pakistan Studies 0448. It covers how Pakistan’s farming systems work, where the main crops and livestock are found, the natural and human factors that affect production, the types of irrigation, the problems of waterlogging and salinity, and how government action has tried to raise output. Answers need named crops, named areas and clear cause-and-effect links.

Where does agriculture fit in 0448 Paper 2?

Agriculture sits between Power (Section 3) and Industrial development (Section 5). It draws on Section 1 (topography and climate decide what grows where) and Section 2 (water supply from dams, barrages and canals). It also feeds Section 5, because cotton, sugar cane and wheat are raw materials for Pakistan’s largest processing industries, and Section 6, because cotton goods and rice are major exports.

CAMBRIDGE IGCSE PAKISTAN STUDIES (0448), 2026 — PAPER 2, SECTION 4: AGRICULTURAL DEVELOPMENT

(a) Agricultural systems

• How small-scale subsistence farming, cash crop farming and livestock farming operate as systems of inputs, processes and outputs

(b) Crops and livestock

• Main areas for cotton, rice, sugar cane and wheat, and for buffalo, cattle, goats, sheep and poultry; recognising them from photographs
• Uses of the four main crops; main livestock products and their uses
• Main areas, reasons for location and an important use of apples, apricots, bananas, dates, maize, mangoes, millet, oilseeds, oranges, pulses, tobacco and vegetables

(c) Factors affecting production

• Natural factors: topography, climate (for kharif and rabi crops), soils, pests and diseases
• Human factors: capital, labour, size of holdings, farming practices, irrigation types and methods, waterlogging and salinity, government action
• Subsistence examples: traditionally grown rice on small, fragmented holdings using family labour; barani (rain-fed) wheat; dates and vegetables under karez irrigation in a desert oasis
• Cash crops: cotton, rice and sugar cane (kharif) and wheat (rabi)
• Livestock on small farms, and nomadic or semi-nomadic herding including transhumance
• Irrigation: karez, inundation and perennial canals; Persian wheel and tubewell; the roles of dams, barrages, link canals, distribution canals, field channels and bunds
• Causes of waterlogging and salinity, restoring damaged land, and preventing it
• Government action: land reforms, training, machinery, chemicals and improved seeds; the possibilities, problems and sustainability of agricultural development

How does a farming system work?

Every farm can be shown as a system:

• Inputs: land, water, seeds, fertiliser, labour, machinery, capital, animals.
• Processes: ploughing, sowing, transplanting, irrigating, weeding, spraying, harvesting, threshing, milking.
• Outputs: crops, milk, meat, wool, eggs, income, and waste such as crop residue.

On a subsistence farm most outputs feed the family. On a cash crop farm outputs are sold, so income becomes an input for next season. A livestock system adds fodder and veterinary care as inputs.

What are kharif and rabi crops?

Season	Sown	Harvested	Main crops
Kharif	Summer, at or before the monsoon	Autumn	Cotton, rice, sugar cane, maize, millet
Rabi	Winter, after the monsoon	Spring	Wheat, pulses (such as gram), oilseeds

Kharif crops need high temperatures and plenty of water. Rabi crops grow in the cooler, drier winter and rely on irrigation, winter rain from western depressions, and moisture stored in the soil.

Where are the main crops grown, and why?

• Cotton: southern Punjab and central Sindh, where summers are long, hot and sunny and canal water is available. It needs a frost-free growing season and dry weather at picking.
• Rice: the “rice belt” of northern Punjab around Gujranwala and Sialkot (known for basmati) and parts of northern Sindh. It needs high temperatures, standing water and clay soils that hold water.
• Sugar cane: central Punjab, central Sindh and the Peshawar valley. It needs heat, a long growing season and a great deal of water.
• Wheat: grown across the irrigated plains of Punjab and Sindh, and on barani land in the Potwar Plateau. It is the staple food crop.

Fruit examples to learn with location and use: mangoes (Multan, southern Punjab, Sindh), oranges (kinnow around Sargodha), dates (Khairpur in Sindh and Balochistan oases), apples and apricots (cooler northern valleys and Balochistan uplands), bananas (Sindh).

How do natural and human factors affect production?

Traditional rice on a small holding. Family labour ploughs with oxen, raises seedlings in a nursery, transplants them by hand into flooded fields, keeps the water level up, and harvests and threshes by hand. Small, fragmented plots make machinery hard to use, and lack of capital limits fertiliser and good seed, so yields stay low.

Barani wheat. On rain-fed land, output depends on winter rainfall. A dry winter means a poor harvest, so farmers take few risks and invest little.

Karez oasis farming. In Balochistan, an underground channel brings groundwater from the foot of the hills to the oasis by gravity. It loses little water to evaporation, but channels need constant cleaning and are being replaced in places by tubewells, which lower the water table.

Livestock. Buffalo and cattle on small farms provide milk, draught power and dung. In the mountains and Balochistan, sheep and goats are herded by nomads or by transhumance, moving to high summer pastures and down to valleys in winter.

Which types of irrigation are used?

Type	How it works	Advantage	Disadvantage
Inundation canal	Takes water only when the river floods	Cheap to build	Water only in the flood season
Perennial canal	Fed from a barrage all year	Reliable year-round supply	Seepage causes waterlogging
Karez	Underground gravity channel	Little evaporation	Labour-intensive to maintain
Persian wheel	Animal-powered wheel lifting well water	Cheap and simple	Small area; slow
Tubewell	Electric or diesel pump from deep wells	Water when needed; lowers water table	Running costs; can over-draw groundwater

Dams store water; barrages raise river level and divert it into canals; link canals move water between rivers; distribution canals and field channels carry it to farms; bunds hold water on fields.

What causes waterlogging and salinity, and how can they be solved?

Seepage from unlined canals and over-watering raise the water table. When it nears the surface the soil becomes waterlogged and roots cannot breathe. In the hot climate, water evaporates and leaves salts behind on the surface, which is salinity.

Restoring land: tubewells pump groundwater out to lower the water table; drainage channels carry salty water away; land is flushed with water and salt-tolerant crops are planted. Prevention: lining canals, more careful water use, and better drainage.

How has government action increased production?

Land reforms set limits on the size of holdings and aimed to transfer land to tenants. Government has also promoted training through agricultural extension work, loans for machinery, subsidised fertiliser and pesticides, and high-yielding seed varieties. Evaluate these: larger landowners have often gained most, and chemicals raise costs and can pollute water.

Frequently asked questions

What is the difference between subsistence and cash crop farming? Subsistence farming grows food mainly for the farmer’s family. Cash crop farming grows crops such as cotton or sugar cane mainly for sale.

What is transhumance? The seasonal movement of herders and their animals between high summer pastures and lower winter grazing.

Why is waterlogging a major problem in the Indus Plain? Large perennial canal systems lose water through seepage, raising the water table, and high evaporation then brings salts to the surface.
