Chapter Summary
Economic Geography is the branch of human geography that studies the location, distribution and spatial organisation of economic activities of human beings on the surface of the earth. It examines how people use the resources of their environment to produce, distribute and consume goods and services. Economic geography is closely linked with other branches of geography such as physical geography (since climate, soil and relief shape economic activity), human geography (population, settlement and culture), political geography (boundaries, trade policy) and environmental geography (sustainability). It also overlaps with economics, statistics and regional planning, but unlike pure economics it always emphasises the spatial or regional dimension of economic phenomena.
The subject matter of economic geography includes the study of the three broad categories of economic activities. Primary activities involve the direct use of natural resources — agriculture, fishing, forestry, animal husbandry and mining. Secondary activities add value to primary products through manufacturing and processing — industries that turn raw materials such as cotton, iron-ore or sugarcane into finished goods. Tertiary activities provide services that support production and people — transport, trade, banking, communication, tourism, education and health. Modern writers also recognise quaternary (knowledge-based) and quinary (high-level decision making) activities. The chapter further deals with patterns of trade, transport networks and regional development, all viewed through a spatial lens.
A resource is anything obtained from the environment that satisfies human needs and is technologically accessible, economically feasible and culturally acceptable. Resources are classified in several ways. On the basis of origin they are biotic (living — plants, animals, fish) and abiotic (non-living — minerals, water, air). On the basis of exhaustibility they are renewable (solar energy, wind, forests, water) and non-renewable (coal, petroleum, minerals). On the basis of ownership they may be individual, community, national or international. On the basis of status of development, resources are described as potential (existing but not yet used, like Rajasthan’s solar energy), developed (surveyed and currently used), stock (known but not usable with present technology, like hydrogen as fuel) and reserve (a part of stock that can be used in future). A further useful division is into natural, human and human-made (man-made) resources.
Land is the most basic resource. India’s land use is broadly classified into net sown area, forest, land under non-agricultural use, barren and waste land, permanent pastures, fallow land and culturable waste. About 43 per cent of India’s land is under cultivation, but forest cover (about 22 per cent) is below the desired 33 per cent suggested by the National Forest Policy. Soil is the topmost layer of the earth’s crust and is the foundation of agriculture. The major soil types of India are alluvial (most fertile, found in the Northern Plains and deltas), black/regur (Deccan Plateau, ideal for cotton), red and yellow (eastern and southern peninsula), laterite (heavy rainfall areas of Karnataka, Kerala, Odisha, north-east), arid/desert (Rajasthan, Gujarat), saline/alkaline (coastal and irrigated dry tracts), peaty/marshy (Kerala, Sundarbans) and forest/mountain soils (Himalayas). Soil erosion by water (sheet, rill, gully) and wind reduces fertility; conservation methods include contour ploughing, terrace farming, strip cropping, shelter belts, afforestation and check dams.
Water resources include surface water (rivers, lakes, ponds, reservoirs) and groundwater (wells, tube-wells, springs). India receives an average annual rainfall of about 117 cm, but it is unevenly distributed. Irrigation through canals, tanks, wells and tube-wells supports agriculture, while multipurpose river projects such as Bhakra-Nangal, Damodar Valley and Hirakud provide water, electricity and flood control. Rainwater harvesting and watershed management are key conservation practices. Mineral resources are divided into metallic (ferrous like iron-ore, manganese; non-ferrous like copper, bauxite, lead), non-metallic (limestone, mica, gypsum) and energy minerals (coal, petroleum, natural gas, uranium, thorium). Major energy sources include conventional ones — coal (Jharia, Raniganj, Bokaro, Korba; Margherita and Makum in Assam), petroleum (Digboi, Naharkatiya, Mumbai High, Bombay High), natural gas, hydroelectricity and firewood — and non-conventional ones — solar, wind, tidal, geothermal, bio-gas and nuclear power. Because most non-renewable resources are getting depleted, sustainable development demands recycling, efficient use, switching to clean energy and protection of biotic resources for the welfare of present and future generations.

Q12. Give two examples of human-made resources.
Answer: Buildings, roads, machinery, bridges and vehicles are examples of human-made resources.
B. Short Answer Questions (2-3 Marks)
Q1. Distinguish between primary and secondary economic activities.
Answer: Primary activities involve the direct extraction or use of natural resources such as agriculture, fishing, mining and forestry. Secondary activities, on the other hand, transform raw materials produced by primary activities into finished or semi-finished goods through manufacturing and processing. Thus, growing cotton is a primary activity while making cloth from cotton is a secondary activity.
Q2. What is the difference between renewable and non-renewable resources?
Answer: Renewable resources can be replenished by natural processes within a short period of time, such as solar energy, wind, water and forests. Non-renewable resources, however, take millions of years to form and once used cannot be replaced quickly; examples are coal, petroleum and most minerals.
Q3. Mention any three causes of soil erosion.
Answer: (i) Deforestation and removal of natural vegetation. (ii) Faulty agricultural practices such as ploughing along the slope and shifting cultivation. (iii) Over-grazing by cattle and the action of running water and strong winds in dry regions.
Q4. Why is conservation of resources necessary?
Answer: Conservation is necessary because most of the resources, especially non-renewable ones, are limited and getting exhausted due to rapidly growing population and industrialisation. Conservation ensures their judicious use, protects the environment, and makes sure that future generations also have access to these resources, which is the essence of sustainable development.
Q5. Distinguish between metallic and non-metallic minerals with examples.
Answer: Metallic minerals contain metals in their raw form and are usually hard, shiny and good conductors of heat and electricity; examples are iron-ore, copper, bauxite and manganese. Non-metallic minerals do not contain metals and are generally non-conductors; examples include limestone, mica, gypsum and coal.
Q6. What are conventional and non-conventional sources of energy? Give examples.
Answer: Conventional sources of energy are those which have been in use since long, such as coal, petroleum, natural gas, firewood and hydroelectricity. Non-conventional sources are comparatively new and pollution-free alternatives such as solar, wind, tidal, geothermal, bio-gas and nuclear energy.
Q7. What is the relationship of economic geography with other branches of geography?
Answer: Economic geography is closely related to physical geography because climate, relief and soil decide the kind of economic activities possible in a region. It is also related to human geography (population, settlement, culture), political geography (boundaries, trade policy) and environmental geography (sustainability and resource use). Thus, economic geography acts as a bridge between the natural environment and human economic life.
Q8. Mention any three methods of water conservation.
Answer: (i) Rainwater harvesting in tanks, ponds and underground reservoirs. (ii) Watershed management to control runoff and recharge groundwater. (iii) Drip and sprinkler irrigation to reduce wastage of water in agriculture, along with re-use and recycling of waste water.
C. Long Answer Questions (5-6 Marks)
Q1. Discuss the subject matter and importance of economic geography.
Answer: Economic geography is the systematic study of the spatial distribution of economic activities and the factors that influence such distribution. Its subject matter covers (i) the nature, classification and use of resources, (ii) the location and patterns of primary, secondary and tertiary activities, (iii) trade, transport and communication networks, and (iv) the regional differences in economic development. The importance of economic geography lies in the fact that it helps in understanding why certain regions are rich while others are poor, in preparing regional development plans, in suggesting suitable locations for industries and agriculture, in promoting balanced use of resources, and in solving problems of unemployment, environmental degradation and inequality. Thus, it links the natural environment with human economic life.
Q2. Explain the classification of resources with suitable examples.
Answer: Resources can be classified on several bases. On the basis of origin, they are biotic (plants, animals, fish, forests) and abiotic (minerals, water, sunlight). On the basis of exhaustibility, they are renewable (solar, wind, forests, water) and non-renewable (coal, petroleum, most minerals). On the basis of ownership, resources are individual (a farmer’s land), community (village ponds), national (mineral wealth) and international (oceans beyond national limits). On the basis of status of development, they are potential (Rajasthan’s solar energy), developed (already in use, like coal of Jharia), stock (hydrogen as fuel — not yet usable) and reserve (a part of stock usable in future). Resources may also be natural (gifts of nature), human (skilled and educated people) and human-made (buildings, machinery, roads). This multi-fold classification helps in proper planning and management.
Q3. Describe the major types of soil found in India and mention their characteristics.
Answer: India has a great variety of soils due to differences in relief, climate and parent rock.
(i) Alluvial soil — formed by the deposition of silt by rivers, found in the Northern Plains and deltas; very fertile, suitable for wheat, rice, sugarcane.
(ii) Black (Regur) soil — formed from lava, found in Deccan Plateau (Maharashtra, Madhya Pradesh, Gujarat); rich in lime and iron, holds moisture, ideal for cotton.
(iii) Red and yellow soil — found in Odisha, Chhattisgarh, southern Deccan; reddish due to iron, less fertile, suitable for millets, pulses.
(iv) Laterite soil — found in areas of heavy rainfall (Karnataka, Kerala, Tamil Nadu, north-east); poor in nutrients, used for tea, coffee and cashew.
(v) Arid/desert soil — found in Rajasthan, Gujarat; sandy, saline, low organic matter.
(vi) Saline/alkaline soil — in dry irrigated and coastal areas; unfit for crops without reclamation.
(vii) Peaty/marshy soil — Kerala, Sundarbans; rich in organic matter.
(viii) Forest/mountain soil — Himalayan slopes; useful for fruits, tea and spices.
Q4. What is soil erosion? Suggest measures for soil conservation.
Answer: Soil erosion is the process by which the top fertile layer of the soil is removed by the agents of running water, wind, glaciers or human activities. It includes sheet erosion, rill erosion, gully erosion and wind erosion. The main causes are deforestation, over-grazing, faulty farming, shifting cultivation and heavy rainfall on bare slopes.
Measures for soil conservation:
(i) Afforestation and re-forestation to bind the soil.
(ii) Contour ploughing along the slopes to reduce the speed of water.
(iii) Terrace farming on hill slopes.
(iv) Strip cropping in which strips of grass are grown between crops.
(v) Construction of check dams in gullies.
(vi) Shelter belts of trees in dry, windy regions to reduce wind erosion.
(vii) Control of over-grazing and shifting cultivation, and use of organic manure to maintain fertility.
Q5. Describe the land use pattern of India and the importance of land as a resource.
Answer: Land is one of the most important natural resources because it is the foundation for agriculture, settlements, industries, transport and forests. The land use pattern of India is broadly classified as follows:
(i) Net sown area — about 43 per cent of the total land, used for cultivation of crops.
(ii) Forest area — about 22 per cent, below the desired 33 per cent recommended by the National Forest Policy.
(iii) Land under non-agricultural use — for buildings, roads, railways, factories and other infrastructure.
(iv) Barren and waste land — rocky, arid or hilly land not fit for cultivation.
(v) Permanent pastures and grazing land — used by livestock.
(vi) Culturable waste land — land left uncultivated for more than five years that can be reclaimed.
(vii) Fallow land — land left uncultivated for one or more agricultural years to restore fertility.
The importance of land lies in the fact that the entire economy depends on it. Hence, scientific land-use planning, prevention of degradation, increase of forest cover and reclamation of waste land are essential to ensure long-term productivity.
Q6. Discuss the major sources of energy in India and the need for sustainable use of resources.
Answer: India uses both conventional and non-conventional sources of energy.
Conventional sources: Coal is the most important source, mined in Jharia, Raniganj, Bokaro, Korba, Singrauli, Talcher and the Margherita-Makum belt of Assam. Petroleum is extracted from Digboi, Naharkatiya, Moran (Assam), Mumbai High and Gujarat fields and refined at Digboi, Numaligarh, Bongaigaon, Barauni and others. Natural gas is found with petroleum and is used both as fuel and as raw material. Hydroelectricity is generated at Bhakra-Nangal, Damodar Valley, Hirakud and Kopili etc.
Non-conventional sources: Solar energy (especially in Rajasthan and Gujarat), wind energy (Tamil Nadu, Gujarat), tidal energy (Gulf of Khambhat, Gulf of Kachchh), geothermal energy, bio-gas and nuclear energy (Tarapur, Kalpakkam, Kaiga, Narora).
Sustainable use means using resources in such a way that the needs of the present generation are met without compromising the ability of future generations to meet their own needs. This requires reducing wastage, recycling, switching from fossil fuels to renewable sources, afforestation, protecting biodiversity and creating public awareness. Only sustainable use can ensure long-term economic growth and environmental balance.
