Case-Based Question 1 – Concept of Resources

A village in Punjab has fertile land, a canal passing nearby, and bright sunshine throughout the year. The villagers have good knowledge of modern farming techniques, but some parts of the land remain unused due to lack of money and machinery. At the same time, a nearby rocky hill with no vegetation is not used at all.

(a) What is a resource?
(b) Identify two examples of resources from the case and state the basis of their classification.
(c) Why is the rocky hill not considered a useful resource for the villagers?
(d) Which condition is missing that prevents some land from becoming a fully developed resource?

Answers:

(a) A resource is anything that can satisfy human needs and is technologically accessible, economically feasible and culturally acceptable.

(b) • Fertile land – a natural, abiotic, renewable resource. • Canal water – a natural, renewable resource. The basis of classification here is origin (abiotic) and exhaustibility (renewable).

(c) The rocky hill is not considered useful because it is not technologically or economically feasible for the villagers to use it for farming or construction. It does not satisfy their current needs.

(d) The missing condition is economic feasibility and technology. The villagers lack sufficient money and machinery to bring all land under cultivation, so part of it has not yet become a fully developed resource.

Case-Based Question 2 – Types of Resources

In a coastal district, people earn their livelihood from fishing, farming on fertile alluvial soil, and working in a nearby mineral-based industry. The government has declared a part of the sea as a protected zone where no one can fish or drill for oil without permission. International ships pass through the deeper regions of the ocean.

(a) Identify one biotic and one abiotic resource from the case.
(b) Which resource category does the protected sea zone belong to in terms of ownership?
(c) How would you classify the mineral-based industry resource: renewable or non-renewable? Give a reason.
(d) Why are international ships not free to use the protected sea zone as they wish?

Answers:

(a) • Biotic resource – Fish. • Abiotic resource – Alluvial soil or minerals used in the industry.

(b) The protected sea zone falls under national resources because it is under the legal control of the government of that country.

(c) Minerals used in the industry are non-renewable resources because they take millions of years to form and cannot be replenished quickly once exhausted.

(d) International ships must follow national and international laws. The protected zone is regulated by the government, so they cannot freely exploit resources there without proper permission.

Case-Based Question 3 – Indiscriminate Use of Resources

A district rich in coal and forests has seen rapid growth of factories and thermal power plants. Over the years, forests have been cleared, air quality has worsened due to smoke, and a river flowing through the area has become polluted with industrial waste. Many local people complain of health problems, and farmers report lower yields due to poor soil quality.

(a) Which type of resource use is described in the passage – sustainable or indiscriminate? Why?
(b) State any two environmental problems caused by this pattern of development.
(c) How can such a district adopt the idea of sustainable development?
(d) Suggest any one step the government can take to balance industrial growth and environmental protection.

Answers:

(a) The passage describes indiscriminate use of resources because coal and forests are being overexploited without care for environmental balance or future generations.

(b) • Air pollution from smoke and industrial emissions. • Water pollution of the river due to industrial waste. (Also soil degradation and health problems.)

(c) The district can adopt sustainable development by: • Using clean technologies and pollution control devices. • Promoting afforestation and conservation of forests. • Encouraging renewable energy along with coal-based power.

(d) The government can enforce strict environmental laws (like mandatory effluent treatment plants) so that industries must control pollution while continuing production.

Case-Based Question 4 – Sustainable Development

In a village, a group of farmers decides to use organic manure instead of chemical fertilisers, adopts crop rotation with pulses, and installs solar pumps for irrigation. They also plant trees along the field boundaries and near the canal. Over a few years, soil fertility improves and water level stabilises.

(a) Which concept from the chapter is best reflected in the actions of these farmers?
(b) How does crop rotation help in sustainable resource use?
(c) State any two benefits of using solar pumps instead of diesel pumps.
(d) Why are trees planted along the field boundaries considered beneficial for soil and water conservation?

Answers:

(a) The actions of these farmers reflect the concept of sustainable development, as they are using resources in a way that protects soil and water for future generations.

(b) Crop rotation with pulses helps because: • Pulses fix nitrogen in the soil, improving fertility. • It reduces the need for chemical fertilisers and prevents soil exhaustion.

(c) Benefits of solar pumps: • They use renewable solar energy, reducing dependence on fossil fuels. • They cause no air pollution and lower running costs for farmers in the long term.

(d) Trees along field boundaries: • Bind the soil with their roots and reduce erosion. • Provide shade and windbreaks, reducing evaporation of water and protecting crops.

Case-Based Question 5 – Steps in Resource Planning

A state government plans to develop a backward region that has forests, rivers and some mineral deposits. First, it conducts surveys and prepares maps showing the location of forests, water sources and minerals. Then, experts prepare a detailed plan suggesting where to set up small industries, irrigation projects and tourism centres. Finally, the government allocates funds and launches schemes to implement these plans.

(a) Which process is described in the passage?
(b) Identify and briefly explain the first step of this process from the case.
(c) Which step is reflected when experts prepare plans for industries and irrigation?
(d) What is the importance of the final stage where funds are allocated and schemes are launched?

Answers:

(a) The passage describes the process of resource planning.

(b) The first step is identification and inventory of resources, where surveys and mapping are done to find out the nature and distribution of forests, rivers and minerals.

(c) This reflects the second step – developing a planning structure for resource development and utilisation according to the needs and potential of the region.

(d) The final stage is important because without proper implementation, funding and schemes, plans remain on paper and do not lead to real development or better use of resources.

Case-Based Question 6 – Uneven Distribution of Resources

Region A has rich deposits of coal and iron ore but poor agricultural land. Region B has fertile soil and abundant water but very few minerals. Region C has neither fertile land nor significant minerals but has a highly educated population and good technology.

(a) What problem related to resources is highlighted by the three regions?
(b) Why is resource planning necessary in such a situation?
(c) How can Region C become developed despite having few natural resources?
(d) Suggest one way in which Regions A and B can cooperate for mutual benefit.

Answers:

(a) The case highlights the problem of uneven distribution of resources across different regions.

(b) Resource planning is necessary to reduce regional imbalances, use each region’s strengths wisely, and ensure that all regions get opportunities for development.

(c) Region C can develop by using its human resources and technology to provide services, IT, research, and by importing raw materials and adding value through manufacturing.

(d) Region A can supply minerals and energy to Region B, while Region B can supply food and agricultural products to Region A. This cooperation benefits both regions.

Case-Based Question 7 – Gandhian View on Resource Use

A Social Science teacher writes the famous quotation of Mahatma Gandhi on the board: “There is enough for everybody’s need but not for anybody’s greed.” She asks students to relate this idea to modern patterns of consumption, where a small section of the population uses more electricity, fuel and water than the rest of the people in the country.

(a) According to Gandhi, what is the difference between ‘need’ and ‘greed’ in the context of resources?
(b) Give one example from daily life where people show greed in using resources.
(c) How can following Gandhi’s idea help in resource conservation?
(d) Suggest any one school-level campaign that can promote need-based use of resources.

Answers:

(a) ‘Need’ refers to using resources only as much as required for a simple and dignified life, whereas ‘greed’ means using resources in an excessive, wasteful and selfish way.

(b) Example: Keeping lights, fans and ACs on unnecessarily or using private vehicles for very short distances instead of walking.

(c) Following Gandhi’s idea reduces wastage and overuse of resources, helps in fair distribution and ensures that resources remain available for future generations.

(d) A school can start a “Save Electricity and Water” campaign, where students check that lights/taps are switched off when not in use and spread awareness through posters and assemblies.

Case-Based Question 8 – Chipko Movement and Resource Conservation

In a hilly region, villagers came together to protest against the cutting of trees by a private company. Women of the village hugged the trees to prevent them from being felled. They argued that forests were essential for fuelwood, fodder, water conservation and protection against landslides.

(a) Which famous people’s movement does this case remind you of?
(b) How do forests act as a resource for villagers?
(c) Mention any two ecological benefits of forests highlighted in the case.
(d) What does this case show about the role of local communities in resource conservation?

Answers:

(a) This case is similar to the Chipko Movement in the Himalayan region.

(b) Forests provide villagers with fuelwood, fodder, small timber and non-timber forest produce, all of which are vital for their daily needs and livelihood.

(c) Ecological benefits: • Forests help in water conservation and maintaining the water cycle. • They protect the soil and slopes, reducing landslides and soil erosion.

(d) The case shows that local communities can play a powerful role in protecting resources, as they directly depend on them and are willing to take collective action for conservation.

Case-Based Question 9 – Importance of Land

A government report on natural resources states that India has a total area of about 3.28 million sq. km. Out of this, some land is used for agriculture, some for forests, and some for non-agricultural uses like buildings, roads and industries. The report warns that pressure on land is increasing due to population growth and changing lifestyles.

(a) Why is land considered a basic natural resource?
(b) Name any two major uses of land in India mentioned in the case.
(c) What is meant by “pressure on land”?
(d) Suggest any one way to reduce pressure on land resources.

Answers:

(a) Land is a basic natural resource because it provides space and support for agriculture, forests, human settlements, industries, and transport systems.

(b) Two major uses of land: • Agriculture (farming). • Non-agricultural uses such as buildings, roads and industries.

(c) “Pressure on land” means that increasing demands of a growing population for food, housing and infrastructure are being placed on a limited and fixed area of land.

(d) One way to reduce pressure on land is to promote vertical development (multi-storey buildings) and efficient land use planning, instead of spreading horizontally.

Case-Based Question 10 – Physical and Human Factors Affecting Land Use

In State X, most of the land in plains is used for intensive agriculture, while in the hilly region of the same state, forests and tea plantations are more common. Over time, a new highway and industries have developed near the plains, converting some agricultural land into non-agricultural use.

(a) Name one physical factor responsible for agriculture in the plains of State X.
(b) Why are forests and tea plantations common in the hilly region?
(c) Which human factor has led to conversion of agricultural land into non-agricultural use?
(d) How can land use planning help in such a situation?

Answers:

(a) One physical factor is the presence of fertile soil and level topography in the plains.

(b) Hilly regions are suitable for forests and plantation crops like tea due to sloping land, high rainfall and cooler climate.

(c) Human factors like development of highways and industries have converted agricultural land into non-agricultural use.

(d) Land use planning can identify which land is best suited for agriculture, forests and industries, so that fertile agricultural land is protected and industries are located on less productive land.

Case-Based Question 11 – Land Use Categories

A table of land use in a district shows area under forests, net sown area, fallow land and land under non-agricultural uses. Over the past ten years, forest area has slightly increased, net sown area has remained nearly the same, fallow land has decreased, and land under non-agricultural uses has increased.

(a) Name any two land use categories mentioned in the case.
(b) What does a decrease in fallow land generally indicate?
(c) Why might forest area have increased slightly?
(d) Give one reason for the increase in land under non-agricultural uses.

Answers:

(a) Two categories: forest area, net sown area, fallow land, or land under non-agricultural uses (any two).

(b) Decrease in fallow land generally indicates that more land is being brought under cultivation, often due to improved irrigation and farming practices.

(c) Forest area may have increased due to afforestation programmes and stricter forest protection laws.

(d) Land under non-agricultural uses may increase due to growth of settlements, industries, roads and public buildings.

Case-Based Question 12 – Net Sown Area and Cropping

In Block Y of a district, the net sown area is 60% of the total area. Due to irrigation facilities, many farmers grow two crops in a year on the same field. As a result, the gross cropped area has reached 110% of the total area.

(a) What is meant by net sown area?
(b) How can gross cropped area be more than 100% of the total area?
(c) What does this case tell you about the intensity of agriculture in Block Y?
(d) Which land resource management issue should farmers keep in mind while increasing cropping intensity?

Answers:

(a) Net sown area is the total area actually sown with crops in a year.

(b) Gross cropped area counts the same field twice if it is sown with two crops in a year. So, if many fields are multi-cropped, gross cropped area can exceed 100% of the total area.

(c) It shows that agriculture in Block Y is intensive, with high cropping intensity due to good irrigation and input use.

(d) Farmers must ensure soil conservation and fertility management, otherwise continuous cropping can lead to soil exhaustion and degradation.

Case-Based Question 13 – Over-Irrigation and Salinisation

In a canal-irrigated area of a north Indian state, farmers have been using excessive water to irrigate their fields for many years. Gradually, the water table has risen, the soil has become waterlogged, and white patches of salt have appeared on the surface. Crop yields have started decreasing.

(a) Which type of land degradation is described in the passage?
(b) Name any two states where such a problem is common.
(c) Suggest two measures to solve the problem in this area.
(d) How is this situation related to the concept of “judicious use of resources”?

Answers:

(a) The passage describes land degradation due to waterlogging and salinisation caused by over-irrigation.

(b) Such problems are common in Punjab, Haryana and western Uttar Pradesh (any two).

(c) • Improve drainage and line canals to prevent seepage. • Use scientific irrigation methods like drip or sprinkler irrigation and avoid over-irrigation.

(d) Over-irrigation shows unjudicious use of water resources. Judicious use means providing only the required amount of water to crops so that soil and water resources are not damaged.

Case-Based Question 14 – Mining and Land Degradation

In a mineral-rich region, open-cast mining has created large pits and heaps of waste material. The top soil has been removed and natural vegetation has disappeared from the mined area. During the rainy season, loose soil and waste are washed into nearby fields and streams, affecting agriculture and water quality.

(a) How does open-cast mining lead to land degradation?
(b) Name any two states of India where mining has caused land degradation.
(c) Suggest any two steps that can be taken to reclaim mined land.
(d) Why should environmental regulations be strictly enforced in mining areas?

Answers:

(a) Open-cast mining removes top soil, leaves deep pits and heaps of overburden, destroys vegetation and makes land unfit for agriculture or habitation.

(b) Mining-related land degradation is common in Jharkhand, Chhattisgarh, Odisha and other mineral-rich states (any two).

(c) • Fill and level the pits and stabilise waste heaps. • Undertake afforestation and grass plantation on reclaimed land.

(d) Strict regulations ensure that mining companies minimise damage, treat waste properly and take responsibility for land reclamation, protecting people’s health and the environment.

Case-Based Question 15 – Regional Nature of Land Degradation

A Geography project compares land degradation in three regions: (i) A desert state affected by wind erosion and overgrazing, (ii) A plateau state affected by mining, (iii) A plain state affected by waterlogging and salt formation due to over-irrigation.

(a) Which three different causes of land degradation are mentioned here?
(b) Match each cause with its region.
(c) Give one suitable conservation measure for each region.
(d) What does this project show about planning for land conservation?

Answers:

(a) The three causes are: wind erosion and overgrazing, mining, and over-irrigation leading to waterlogging and salinity.

(b) • Desert state – wind erosion and overgrazing. • Plateau state – mining. • Plain state – over-irrigation, waterlogging and salinity.

(c) • Desert state – plant shelter belts and control grazing. • Plateau state – reclaim mined land by levelling and afforestation. • Plain state – improve drainage and adopt scientific irrigation methods.

(d) The project shows that land conservation requires region-specific measures according to the local causes of degradation; one common solution cannot work everywhere.

Case-Based Question 16 – Factors of Soil Formation

In a hilly region, the soil is shallow and full of stones, while in the river valley below, the soil is deep and fertile. The area receives heavy rainfall, and dense vegetation grows on the slopes. Over many years, fallen leaves and plant remains have mixed with the upper layer of soil in the valley.

(a) Name any three factors of soil formation visible in this case.
(b) Why is soil shallow and stony on the slopes but deep and fertile in the valley?
(c) How does vegetation contribute to soil formation and fertility?
(d) Why is soil formation considered a slow process?

Answers:

(a) Three factors: relief (slope), climate (heavy rainfall), and flora (dense vegetation). Parent rock and time are also factors.

(b) On slopes, rainwater washes away soil, leaving it shallow and stony. In the valley, eroded material and alluvium get deposited, forming deep and fertile soil.

(c) Vegetation adds organic matter through fallen leaves and roots. Microorganisms decompose it to form humus, which improves soil structure and fertility.

(d) Soil formation takes hundreds to thousands of years because rocks weather slowly, and processes of deposition and humus formation take a long time. Hence, soil is a slowly renewable resource.

Case-Based Question 17 – Alluvial Soil and Agriculture

A farmer in the Ganga plain grows rice in the kharif season and wheat in the rabi season on his field. The soil is deep, light in colour and easy to plough. He says that the river deposits fresh silt every year during floods, making the land very fertile.

(a) Which type of soil is described in this case?
(b) Name any two characteristics of this soil that make it ideal for agriculture.
(c) Mention any two crops, other than rice and wheat, that can be grown in this soil.
(d) How is the annual deposition of silt beneficial for the farmer?

Answers:

(a) The soil described is alluvial soil.

(b) • It is deep and fertile. • It is easy to plough and has good moisture-retaining capacity.

(c) Other crops: sugarcane, pulses, oilseeds, jute, maize (any two).

(d) Fresh silt replenishes nutrients in the soil each year, maintaining high fertility and good yields without excessive use of fertilisers.

Case-Based Question 18 – Black Soil and Cotton Cultivation

In a part of the Deccan plateau, farmers grow cotton as the main crop. The soil is dark in colour, sticky when wet, and develops wide cracks during the dry season. It retains moisture for a long time, helping cotton plants survive in dry months.

(a) Identify the soil type described.
(b) Why is this soil suitable for cotton cultivation?
(c) Name any two states where such soil is commonly found.
(d) Mention any one more crop that can be grown in this soil.

Answers:

(a) The soil is black soil (regur soil).

(b) It is suitable for cotton because it has high clay content and moisture-holding capacity, which helps cotton during dry periods.

(c) States: Maharashtra, Madhya Pradesh, Gujarat, Andhra Pradesh, Karnataka (any two).

(d) Another crop: sugarcane, wheat, soyabean, pulses (any one).

Case-Based Question 19 – Soil Erosion in Hilly Areas

A village in the hills experiences heavy rainfall every monsoon. Farmers plough their fields up and down the slope. During rains, water flows rapidly down the slope, washing away the top soil and creating small channels and gullies. Over time, the fields have become less fertile.

(a) Which type of soil erosion is seen in this case?
(b) Name any two wrong farming practices that increase erosion in the case.
(c) Suggest any two methods to control soil erosion in this area.
(d) How will these methods help protect soil fertility?

Answers:

(a) The case shows rill and gully erosion, as water cuts small channels and gullies in the soil.

(b) • Ploughing up and down the slope. • Lack of proper terracing or contour bunding.

(c) • Contour ploughing along the slope lines. • Terrace farming and planting grasses/trees on slopes.

(d) These methods slow down the flow of water, reduce the washing away of top soil, and help retain moisture and nutrients, thus protecting soil fertility.

Case-Based Question 20 – Soil Conservation in Arid Regions

In a desert district, strong winds often blow away loose sand and top soil from fields, burying young crops under sand dunes. To reduce this problem, farmers have started planting rows of trees and shrubs along the edges of their fields and on open land.

(a) Which agent of soil erosion is active in this region?
(b) What is the name of the method where rows of trees are planted to reduce wind speed?
(c) How does this method help in soil conservation?
(d) Name any one Indian state where such a problem is common and such methods are used.

Answers:

(a) The main agent of soil erosion here is wind.

(b) The method is called planting shelter belts or windbreaks.

(c) Rows of trees reduce the speed of wind, trap moving sand, and bind the soil with their roots, thereby preventing soil from being blown away.

(d) Such problems are common in parts of Rajasthan, where shelter belts and afforestation are used to control desertification.
