भूगोल Geography

Quick summary

Economic geography studies how economic activities — production, exchange and consumption — are spread over the earth's surface and why. It explains the location of agriculture, industries, transport, trade and services in relation to physical and human factors. Economic activities are classified as primary, secondary, tertiary, quaternary and quinary.

Key points

• Economic geography (आर्थिक भूगोल) is the branch of human geography dealing with the spatial distribution of economic activities and resources.
• It answers: what is produced, where, why there, and how it is exchanged.
• George G. Chisholm's Handbook of Commercial Geography (1889) is an early classic work.
• It is linked with economics, but focuses on space and location.
• Approaches: commodity approach (one product across the world), regional approach (all activities of a region), systematic/topical approach (one activity), and principles approach (location theories).
• Location theories: von Thünen (agricultural land use, 1826), Alfred Weber (industrial location, 1909), Walter Christaller (central place theory, 1933).
• Modern economic geography studies globalisation, multinational companies, IT services and regional inequality.
• In India, the shift from agriculture towards services shows economic change over time.

Important terms

• Primary activities – directly use natural resources: agriculture, fishing, forestry, mining, hunting, gathering. Workers are called red-collar workers.
• Secondary activities – manufacturing and processing of raw materials into finished goods (blue-collar).
• Tertiary activities – services: trade, transport, communication, banking, health, education.
• Quaternary activities – knowledge-based services: research, information technology, data processing (white-collar).
• Quinary activities – top-level decision making by senior executives, policymakers and officials (gold-collar).
• Resource – anything useful to humans that is technically possible, economically feasible and culturally acceptable.

Quick summary

A resource is anything in the environment that can satisfy human needs, provided it is technically possible, economically feasible and culturally acceptable. Resources are classified by origin, renewability, ownership and development status. Over-use of resources causes depletion and pollution, so conservation and sustainable development are necessary.

Key points

• Erich Zimmermann said "Resources are not, they become" — something becomes a resource only when humans find a use for it.
• Resources (संसाधने) are classified in several ways:
• By origin: biotic (living — forests, animals, fish) and abiotic (non-living — minerals, water, land).
• By exhaustibility: renewable (solar energy, wind, water, forests) and non-renewable (coal, petroleum, minerals).
• By ownership: individual, community, national and international.
• By development: potential, developed (actual), stock and reserves.
• Sustainable development: meeting the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland Report, Our Common Future, 1987).
• Rio Earth Summit (1992) adopted Agenda 21 for sustainable development.
• Conservation methods: reduce, reuse, recycle; afforestation; rainwater harvesting; watershed management; use of renewable energy; soil conservation; protected areas.
• Indian movements: Chipko movement (1973, Uttarakhand), Appiko movement (Karnataka). In Maharashtra, villages like Ralegan Siddhi (Anna Hazare) and Hiware Bazar are known for watershed development.

Important terms

• Potential resource – exists but not yet used, e.g. wind and solar energy in many areas.
• Stock – resources that exist but cannot be used with present technology, e.g. hydrogen as fuel.
• Reserves – part of stock that can be used with present technology but is kept for the future.
• Conservation – wise and planned use of resources to avoid waste.
• Ecological footprint – the amount of land and water needed to support a person's lifestyle.
• Watershed – the area drained by a river or stream; watershed management conserves soil and water.

Key facts

• Maharashtra examples: Tadoba-Andhari and Pench tiger reserves; Jalyukt Shivar Abhiyan for water conservation.

5 important questions

Q1. What is meant by "resources are not, they become"?

It means that a substance becomes a resource only when humans have the knowledge, technology and need to use it. This idea was given by Zimmermann.

Q2. Define sustainable development.

Development that meets the needs of the present generation without compromising the ability of future generations to meet their own needs (Brundtland Report, 1987).

Q3. Classify resources with examples.

• Biotic and abiotic.
• Renewable and non-renewable.
• Individual, community, national, international.
• Potential, developed, stock, reserves.
• Examples for each.

Q4. Why is conservation of resources necessary?

• Non-renewable resources are limited.
• Rapid population growth and consumption.
• Over-use causes pollution and land degradation.
• Loss of biodiversity.
• Climate change from fossil fuel use.
• Needs of future generations.

Q5. Explain methods of conservation of resources.

• Reduce, reuse, recycle.
• Soil and water conservation: terracing, check dams, watershed programmes.
• Forest conservation and afforestation.
• Renewable energy.
• Laws and policies: Wildlife Protection Act 1972, Forest Conservation Act 1980.
• People's participation: Chipko, Ralegan Siddhi.

Exam tip

Write the classification as a tree diagram. Quote the Brundtland definition word-perfect and give Maharashtra examples of watershed conservation.

Quick summary

Minerals and energy resources are the raw base of modern industry and transport. They are unevenly distributed over the world, which creates trade, wealth and sometimes conflict. This topic covers the world pattern of iron ore, bauxite, copper, coal, petroleum, natural gas and the growing renewable sources.

Key points

• Minerals are non-renewable and exhaustible; their distribution depends on geology.
• Iron ore: Australia (Pilbara region) is the largest producer and exporter, followed by Brazil (Carajás, Itabira), China, India and Russia.
• Bauxite: Australia, Guinea and China lead; it is the ore of aluminium.
• Copper: Chile is the largest producer (Atacama region); Peru, Congo (DR) and the USA are also important.
• Coal: the main fuel for electricity and steel. China produces about half of the world's coal; India is second; Indonesia, the USA and Australia follow. Major fields: Appalachian (USA), Ruhr (Germany), Donbas (Ukraine), Shanxi (China), Damodar (India).
• Petroleum: the USA, Saudi Arabia and Russia are the top producers. The largest reserves are in Venezuela, Saudi Arabia and the Persian Gulf region.
• OPEC (Organisation of the Petroleum Exporting Countries) was founded in 1960 in Baghdad; its headquarters is in Vienna.
• Natural gas: the USA and Russia are the leading producers; Russia, Iran and Qatar hold the largest reserves. It is a cleaner fuel than coal.
• Nuclear energy uses uranium; Kazakhstan is the largest uranium producer. France gets most of its electricity from nuclear power.
• Renewable energy: hydropower (China – Three Gorges Dam, Brazil, Canada), solar and wind (China leads, followed by the USA, Germany and India), geothermal (Iceland, New Zealand), tidal (La Rance in France).
• The world is shifting to renewables because of fossil-fuel depletion, pollution and climate change.
• Note: rankings change every year – check the latest figures.

Important terms

• Fossil fuels (जीवाश्म इंधने) – coal, oil and gas formed from ancient plants and animals.
• Reserves – known amounts that can be extracted with present technology and cost.
• Renewable resource – a resource that is naturally replaced (sun, wind, water).
• Energy security – reliable supply of energy at affordable prices.
• Energy transition – shift from fossil fuels to clean energy.

Key facts

5 important questions

Q1. What is OPEC?

The Organisation of the Petroleum Exporting Countries, formed in 1960 in Baghdad, which coordinates the petroleum policies of major oil-exporting countries; its headquarters is in Vienna.

Q2. Why is natural gas called a clean fuel?

Because it burns more completely than coal or oil and releases less carbon dioxide, smoke and sulphur.

Q3. Describe the world distribution of iron ore.

• Types of ore and uses.
• Major producing regions: Australia, Brazil, China, India, Russia, Sweden.
• Export flows to China, Japan, Korea.
• World map with regions.

• Advantages and limitations.
• Future of energy; India's role.

Exam tip

Learn the top two producers of each resource and show them on a world map; for oil, always mention the Persian Gulf and OPEC.

Quick summary

Primary activities depend directly on nature. Besides agriculture, the main primary activities are forestry (using forests for timber and other products), fishing (catching fish and other sea food) and mining (extracting minerals from the earth). Their location is controlled mainly by physical factors such as climate, forests, coasts, ocean currents and geology.

Key points

• About one-third of the earth's land is under forests. Major forest types: tropical evergreen (Amazon, Congo – hardwoods like mahogany, ebony), tropical deciduous (monsoon lands – teak, sal), temperate and coniferous (taiga) forests of Canada, Russia and Scandinavia (softwoods like pine, spruce, fir).
• Commercial forestry is most developed in coniferous forests because trees are soft, grow in pure stands, are easy to cut and float down rivers; they supply timber, pulp and paper.
• Forest products: timber, fuelwood, pulp, resin, lac, honey, bamboo, tendu leaves (bidi), medicinal plants. Problems: deforestation, shifting cultivation, fires, mining. Remedies: afforestation, social forestry, Joint Forest Management.
• Fishing is best developed where there is a wide continental shelf, mixing of warm and cold currents, plenty of plankton, cool water, an indented coastline and good markets.
• Major fishing grounds: North-West Pacific (Japan, China – the largest), North-East Atlantic (North Sea, Dogger Bank), North-West Atlantic (Grand Banks of Newfoundland), South-East Pacific (Peru – anchovy).
• Types of fishing: inland (rivers, lakes, ponds), coastal, deep-sea; and aquaculture (fish farming). India is among the top fish producers; Andhra Pradesh leads in inland and aquaculture output, while Gujarat, Kerala and Maharashtra are important for marine fish. The Blue Revolution aims to raise fish production.
• Mining methods: open-cast (surface) mining for shallow deposits (coal at Chandrapur), shaft (underground) mining for deep deposits, placer (alluvial) mining of river sand for gold and tin, drilling for oil and gas, and quarrying for stone.
• Factors affecting mining: size and quality of deposit, depth, technology, transport, capital, demand and prices.
• Effects of mining: land degradation, deforestation, water and air pollution, displacement, health hazards – so reclamation and safety laws are needed.

Important terms

• Forestry (वनव्यवसाय) – management and use of forests.
• Afforestation – planting trees on land without forests.
• Plankton – tiny plants and animals floating in water; fish food.
• Aquaculture – rearing fish and other aquatic organisms in controlled waters.
• Open-cast mining – removing surface layers to reach minerals near the surface.
• Overfishing – catching fish faster than they can reproduce.

Key facts

5 important questions

Q1. Why is commercial forestry well developed in coniferous forests?

Because conifers are softwoods that grow in pure stands, are easy to cut and transport by river, and are in great demand for pulp, paper and timber.

Q2. What is open-cast mining?

A method in which the overlying soil and rock are removed to extract minerals that lie close to the surface, e.g. coal mines in the Wardha valley.

Q3. Explain the factors favouring fishing and describe the major fishing grounds of the world.

• Physical factors: shelf, currents, plankton, cool water, coastline.
• Economic factors: market, technology, capital, storage.
• Four major fishing grounds with features; map.
• Problems: overfishing, pollution.

Q4. Describe the types of forests and their economic importance.

• Tropical evergreen, deciduous, temperate, coniferous – location and trees.
• Products and industries based on forests.
• Forests in Vidarbha: teak, bamboo, tendu leaves.
• Conservation measures.

Q5. Explain the methods of mining and its environmental effects.

• Open-cast, shaft, placer, drilling, quarrying.
• Factors affecting mining.
• Environmental and social effects.
• Measures: reclamation, afforestation, safety rules, sustainable mining.

Exam tip

Link each activity to one local example – Vidarbha teak and bamboo, Konkan fishing, Chandrapur coal – it makes your answer stand out.

Quick summary

Agriculture varies across the world depending on climate, soil, technology, capital and markets. Major types include primitive subsistence (shifting cultivation and nomadic herding), intensive subsistence farming, plantation agriculture, extensive commercial grain farming, mixed farming, dairy farming, Mediterranean agriculture and market gardening. Each type has its own features and regions.

Key points

• Agriculture (शेती) includes growing crops and rearing animals.
• Classification of agricultural systems by D. Whittlesey (1936) is widely used.
• Shifting cultivation (slash-and-burn): forest is cleared and burnt, crops grown for a few years, then the plot is left. Local names: jhum (north-east India), milpa (Central America), ladang (Malaysia and Indonesia).
• Nomadic herding: herders move with animals in search of pasture; in Sahara, Central Asia, Tundra. Examples: Bedouins, Maasai, Lapps (Sami).
• Intensive subsistence agriculture: small farms, high labour, high yields per hectare; rice-dominated in the monsoon lands of South and East Asia.
• Plantation agriculture: large estates growing a single cash crop (tea, coffee, rubber, sugarcane, banana) for export, using large capital and labour; introduced by Europeans in their colonies.
• Extensive commercial grain farming: huge mechanised farms growing wheat in temperate grasslands — Prairies (North America), Pampas (Argentina), Steppes, Downs (Australia). High yield per worker, low yield per hectare.
• Mixed farming: crops and livestock together; common in Western Europe and eastern USA.
• Dairy farming: rearing milch animals; near cities; capital intensive; north-west Europe, New Zealand.
• Mediterranean agriculture: citrus fruits, grapes (wine), olives, figs; dry summers and rainy winters.
• Market gardening and horticulture: vegetables, fruits and flowers grown for nearby urban markets.

Important terms

• Subsistence agriculture – farmers grow food mainly for their own family.
• Commercial agriculture – produce is grown mainly for sale.
• Transhumance – seasonal movement of herders and animals between mountains (summer) and valleys (winter); e.g. Gujjars and Bakarwals of Jammu–Kashmir and Himachal.
• Viticulture – cultivation of grapes; important in the Mediterranean and in Nashik.
• Truck farming – market gardening where produce is sent by truck overnight to markets.
• Kolkhoz and sovkhoz – collective and state farms of the former Soviet Union.

Key facts

5 important questions

Q1. What is shifting cultivation?

It is a primitive type of farming in which a patch of forest is cleared by cutting and burning, crops are grown for a few years until fertility falls, and then the farmer moves to a new patch.

Q2. What is transhumance?

Transhumance is the seasonal movement of herders with their animals — to high mountain pastures in summer and back to lower valleys in winter.

Q3. Describe the characteristics of intensive subsistence agriculture.

• Small and fragmented holdings.
• High use of human labour; little machinery.
• High yield per hectare but low per worker.
• Rice dominant; double or triple cropping where water is available.
• Use of manure and irrigation.
• Found in densely populated monsoon Asia.

Q4. Explain plantation agriculture.

• Large estates, single crop, export oriented.
• Large capital, scientific methods, processing on estate.
• Cheap labour; good transport to ports.
• Crops: tea (Assam, Sri Lanka), coffee (Brazil, Karnataka), rubber (Malaysia, Kerala).
• Colonial origin.
• Problems: price fluctuations, dependence on one crop.

Q5. Describe extensive commercial grain farming.

• Temperate grasslands with low population.
• Very large farms, highly mechanised.
• Mainly wheat; also barley, oats.
• Low yield per hectare, high yield per person.
• Regions: Prairies, Pampas, Steppes, Downs, Veld.
• Good transport for export.

Exam tip

Use a table with type, features, crops and regions. Draw a world map marking at least four types — maps get extra marks in geography.

Quick summary

Von Thünen's theory explains how farm land use is arranged around a market town. In his model, the cost of transporting produce to the market decides which crop is most profitable at each distance, so land use forms concentric rings around the city. It is the first model of agricultural location and is still useful for understanding land use near cities.

Key points

• Johann Heinrich von Thünen, a German landowner and economist, explained the theory in his book The Isolated State (Der isolierte Staat), 1826.
• Assumptions: an isolated state with one central city as the only market; a flat, uniform plain (same soil and climate everywhere); one mode of transport (horse and cart); transport cost rises directly with distance; farmers aim at maximum profit; no trade with the outside world.
• The key idea is economic (locational) rent – the net profit per unit of land after paying production and transport costs. A crop is grown where it gives the highest rent.
• Perishable and bulky goods are produced near the city; goods that are cheap to transport or need large areas are produced far away.
• Ring 1 – market gardening and dairying: vegetables, fruits and milk, which are perishable.
• Ring 2 – forestry: firewood and timber, which were heavy and bulky (in Thünen's time the city needed fuelwood).
• Ring 3 – intensive crop rotation: grains and root crops without fallow.
• Ring 4 – crop rotation with grass/fallow (long rotation).
• Ring 5 – three-field system: one field of every three left fallow.
• Ring 6 – livestock ranching / extensive grazing; beyond this lies wilderness.
• Modifications: a navigable river (cheaper transport) stretches the rings along it; a second small town creates its own small rings.
• Criticism: assumptions are unreal; modern transport (trucks, refrigeration) has changed distances; ignores government policy, relief and soils; forestry no longer in ring 2.
• Relevance: around Indian cities like Nagpur, Pune or Mumbai we still see vegetable, flower and milk zones close to the city and field crops farther away.

Important terms

• Economic rent / locational rent – net return per unit of land at a given distance from the market.
• Isolated state – Thünen's imaginary self-sufficient region with one market.
• Isotropic plain – a flat surface with uniform conditions in all directions.
• Intensity of land use – amount of labour and capital applied per unit of land.
• Margin of cultivation – the distance at which economic rent becomes zero.

Formulas

• Economic rent: R = Y (p − c) − Y f d
• R = rent per hectare, Y = yield per hectare, p = market price per unit, c = production cost per unit, f = freight (transport) rate per unit per km, d = distance from market in km.
• Margin of cultivation (where R = 0): d = (p − c) ÷ f

5 important questions

Q1. Calculate the economic rent for a crop with yield 10 tonnes/ha, price ₹1,000/tonne, production cost ₹600/tonne, transport cost ₹20 per tonne per km, at 5 km from the market. Also find the margin of cultivation.

1. R = Y (p − c) − Y f d
2. R = 10 × (1,000 − 600) − 10 × 20 × 5
3. R = 4,000 − 1,000 = ₹3,000 per hectare
4. Margin: d = (p − c) ÷ f = 400 ÷ 20 = 20 km. Beyond 20 km this crop gives no profit.

Q2. Why did Thünen place forestry in the second ring?

Because in his time the city needed large amounts of firewood and timber, which were heavy and bulky and costly to transport, so they had to be produced close to the city.

Q3. Explain von Thünen's theory of agricultural location with a diagram.

• Introduction and book.
• Assumptions.
• Concept of economic rent with formula.
• Six rings with land use and reasons.
• Concentric-ring diagram.

Q4. Describe the modifications of the model and its criticism.

• Effect of a navigable river and a second town (diagram).
• Criticism: unreal assumptions, modern transport, ignores physical and political factors.
• Merits: first location model, basis for later theories, shows role of distance.

Q5. Discuss the relevance of von Thünen's theory today, with Indian examples.

• Peri-urban zones of vegetables, flowers, dairy near metros.
• Global-scale rings (Europe as market).
• Changes due to refrigeration, roads, cold chains.
• Conclusion: the principle of distance-decay still holds.

Exam tip

Practise one economic-rent sum; a correct numerical with the formula and margin of cultivation is the easiest full-mark question in this unit.

Quick summary

Industrial location means the place where an industry is set up. Industries choose places where production and transport costs are lowest and profits highest. Location depends on geographical factors (raw materials, power, water, climate) and non-geographical factors (labour, capital, market, transport, government policy). Alfred Weber's least-cost theory (1909) is the classic explanation.

Key points

• Factors affecting industrial location (उद्योगांचे स्थान):
• Raw materials: weight-losing or perishable raw materials pull industries close to their source (sugar, iron and steel).
• Power: early industries grew near coalfields; hydro-electricity attracted aluminium plants.
• Labour: availability of cheap or skilled labour (IT in Bengaluru and Pune).
• Market: industries making perishable or bulky final goods locate near markets.
• Transport: ports, railways and highways reduce cost.
• Capital and banking, water supply, climate (humid climate for cotton spinning), government policy (tax benefits, backward area incentives, SEZs), industrial inertia and agglomeration economies.
• Alfred Weber's Theory of Industrial Location (1909): industries locate at the point of least total transport cost, then adjust for labour cost and agglomeration.
• Weber's assumptions: isolated country, uniform terrain, fixed locations of raw materials and market, transport cost proportional to weight and distance, perfect competition.
• Weber classified raw materials as ubiquitous (found everywhere, e.g. water, clay) and localised (found only at certain places, e.g. iron ore, coal). Localised ones may be pure (no weight loss, e.g. cotton) or gross/weight-losing (e.g. sugarcane, iron ore).
• He used the locational triangle (two raw material sources and one market) and the material index.

Important terms

• Footloose industry – not tied to raw materials; can be located almost anywhere (electronics, software, diamond cutting).
• Industrial inertia – an industry continues at its old site even after original advantages are lost.
• Agglomeration economies – cost savings when many industries cluster together (shared services, labour, suppliers).
• Isodapanes – lines joining points of equal additional transport cost (Weber).
• Material index – weight of localised raw materials ÷ weight of finished product.

Key facts

• Material index (MI) = weight of localised raw materials ÷ weight of finished product.
• If MI > 1 (weight-losing material), the industry locates near the raw material source (e.g. sugar mills, iron and steel).
• If MI < 1 (weight-gaining, e.g. using ubiquitous water), it locates near the market (e.g. soft drinks, bakery).
• If MI = 1 (pure material), it may locate at the source, market or anywhere in between.
• Example: if 10 tonnes of sugarcane give about 1 tonne of sugar, MI = 10 ÷ 1 = 10 → location near cane fields.
• Other theorists: August Lösch (maximum profit / market area approach), Edgar Hoover (transport costs), David M. Smith (spatial margins of profitability).

5 important questions

Q1. What is a footloose industry?

A footloose industry is one that can be located at a wide variety of places because it does not depend on any specific raw material or heavy transport, e.g. software and electronics.

Q2. What does a material index greater than one show?

It shows a weight-losing raw material, so the industry should locate near the raw material source to save transport cost.

Q3. Explain the geographical factors of industrial location.

• Raw materials: weight-losing and perishable.
• Power resources: coal, hydro-power.
• Water supply: steel, chemicals, textiles.
• Climate: humid climate for cotton textiles (Mumbai).
• Land and topography.
• Examples from India.

Q4. Explain the non-geographical factors of industrial location.

• Labour: cheap and skilled.
• Capital and banking.
• Market and transport.
• Government policies: incentives, SEZs, MIDC estates.
• Agglomeration and industrial inertia.
• Political stability.

Q5. Explain Weber's theory of industrial location.

• Least-cost location; transport cost most important.
• Assumptions listed.
• Ubiquitous and localised materials; material index.
• Locational triangle.
• Labour cost and agglomeration deviations; isodapanes.
• Criticism: unrealistic assumptions, ignores demand and government policy.

Exam tip

Draw Weber's locational triangle (M1, M2, C with point P) and explain the material index with the sugarcane example — clear, simple and scoring.

Quick summary

Iron and steel and cotton textiles are two of the world's most important manufacturing industries. Iron and steel is a heavy, basic industry that supplies material to almost all other industries; cotton textiles is one of the oldest modern industries and employs millions. Their location depends on raw materials, power, labour, markets and transport.

Key points

• Iron and steel is called a basic or key industry because machines, railways, ships, buildings and vehicles all need steel.
• Raw materials: iron ore, coking coal, limestone and manganese; large amounts of water and power are also needed. Since raw materials lose much weight, plants locate near coal, near ore, or at ports where both can be imported.
• Early plants grew on coalfields: Ruhr (Germany), Pittsburgh (USA), Birmingham and Sheffield (UK), Donbas (Ukraine). Modern plants are often at tidewater (coastal) sites: Baltimore (USA), IJmuiden (Netherlands), Japanese and Korean ports, Visakhapatnam (India).
• China produces more than half of the world's steel; India is the second-largest producer, followed by Japan, the USA and Russia (figures change yearly).
• India: TISCO, Jamshedpur (founded 1907 by the Tata group, near Jharkhand's ore and coal), Bhilai (with Soviet help), Rourkela (German), Durgapur (British), Bokaro (Soviet), Visakhapatnam (India's first shore-based plant). In Maharashtra: steel plants at Dolvi (Raigad) and Tarapur, and sponge-iron units in Chandrapur and Wardha.
• Cotton textile needs raw cotton, a humid climate (yarn breaks less), cheap skilled labour, soft water for bleaching and dyeing, power, capital and a large market.
• World centres: Lancashire (Manchester), UK – the first centre of the Industrial Revolution (humid climate, Liverpool port, coal); New England and the southern USA; Osaka ("Manchester of Japan"); China (the largest producer today), India, Bangladesh, Pakistan.
• India: the first successful mill was set up in Mumbai in 1854. Mumbai became "Cottonopolis of India"; Ahmedabad is called the "Manchester of India"; Coimbatore the "Manchester of South India". In Vidarbha, the Empress Mills, Nagpur (Tata, 1877) was a pioneer; Ichalkaranji and Bhiwandi are big powerloom centres.
• Problems: old machinery, competition from synthetic fibres and cheap imports, power shortages; for steel – high energy use and pollution.

Important terms

• Basic industry – an industry whose products are raw material for other industries.
• Coking coal – coal suitable for making coke used in blast furnaces.
• Blast furnace – a furnace in which iron ore is smelted with coke and limestone.
• Tidewater location – an industrial site at a port.
• Powerloom – a mechanised loom run by electricity, usually in small units.

Key facts

5 important questions

Q1. Why is iron and steel called a basic industry?

Because its products are the raw material for many other industries such as machinery, transport equipment, construction and defence.

Q2. Why is Ahmedabad called the Manchester of India?

Because, like Manchester, it grew into a major cotton-textile centre with many mills, supported by nearby cotton-growing areas, a humid climate, capital and skilled labour.

Q3. Explain the factors of location of the iron and steel industry with world examples.

• Raw materials and their weight loss.
• Coalfield, orefield, intermediate and tidewater locations.
• Examples: Ruhr, Pittsburgh, Lorraine, Japan's coast.
• Modern trends: mini steel plants, scrap-based electric furnaces.

Q4. Describe the distribution of the cotton textile industry in the world.

• Location factors.
• UK (Lancashire), USA, Japan, China, India, Bangladesh.
• Shift from developed to developing countries; reasons.
• World map.

Q5. Describe the growth and distribution of iron-and-steel and cotton-textile industries in India.

• Steel: history, integrated plants, private sector, Maharashtra's share.
• Cotton: Mumbai 1854, Ahmedabad, Coimbatore, Nagpur, powerloom centres.
• Problems and remedies; contribution to jobs and exports.

Exam tip

For each industry, write location factors first and then examples; always add one Maharashtra centre (Empress Mills Nagpur, Dolvi steel plant).

Quick summary

Transport is the movement of people and goods from one place to another, while trade is the exchange of goods and services. Good transport links production with markets and supports trade. The main modes are roads, railways, waterways, airways and pipelines. Trade can be internal or international, and the balance of trade shows the relationship between a country's exports and imports.

Key points

• Transport and communication are called the lifelines of an economy.
• Road transport: flexible, door-to-door, best for short distances. India has one of the largest road networks in the world. The Golden Quadrilateral links Delhi, Mumbai, Chennai and Kolkata. The Mumbai–Pune Expressway was India's first six-lane access-controlled expressway.
• Rail transport: cheap for bulky goods over long distances. India's first passenger train ran from Bombay (Bori Bunder) to Thane on 16 April 1853.
• Water transport: cheapest for heavy and bulky goods; inland waterways and ocean routes. Major sea routes: North Atlantic route (busiest), Suez Canal route, Cape of Good Hope route, Panama Canal route.
• The Suez Canal (opened 1869) joins the Mediterranean and Red Sea; the Panama Canal (opened 1914) joins the Atlantic and Pacific oceans.
• Air transport: fastest, costly; useful for perishable and valuable goods and remote areas.
• Pipelines: carry oil, gas and water; e.g. the Hazira–Vijaipur–Jagdishpur (HVJ) gas pipeline.
• Major ports of Maharashtra: Mumbai Port and Jawaharlal Nehru Port (Nhava Sheva), one of India's busiest container ports.
• Trade (व्यापार) may be internal (domestic) or international. International trade may be bilateral or multilateral.
• The World Trade Organization (WTO) was set up on 1 January 1995, replacing GATT.

Important terms

• Balance of trade – difference between the value of exports and imports of goods.
• Favourable (surplus) balance – exports greater than imports; unfavourable (deficit) – imports greater than exports.
• Balance of payments – record of all economic transactions of a country with the world, including services and capital.
