Chapter Overview – Resources and Development

This chapter, Resources and Development, forms the foundation of Geography for Class 10. It explains how different types of resources are available on the Earth, how they are developed and planned, and why their judicious use is essential for sustainable development. The chapter also focuses on land resources, land use pattern, land degradation, soil types, soil erosion and soil conservation, which are very important for CBSE Board examinations.

All concepts in these revision notes are explained as per NCERT, using simple language, exam-oriented headings, and clear points to help you write high-scoring answers in the CBSE Class 10 Social Science exam.

1. Concept of Resources

The word resource refers to all the things available in our environment which can be used to satisfy human needs, provided they are:

• Technologically accessible
• Economically feasible
• Culturally acceptable

Thus, resources are not just materials available in nature. Something becomes a resource only when:

• Humans have the knowledge and technology to use it, and
• It can be used profitably and usefully in a given society.

1.1 Types of Resources (On Different Bases)

(a) On the basis of Origin

• Biotic Resources: Obtained from the biosphere; they have life.
  Example: Plants, animals, human beings, fisheries, livestock, etc.
• Abiotic Resources: Non-living resources.
  Example: Rocks, minerals, metals, water, air, etc.

(b) On the basis of Exhaustibility

• Renewable (Replenishable) Resources:
  These can be renewed or reproduced by physical, chemical or mechanical processes.
  Example: Solar energy, wind energy, water, forests, wildlife.
• Non-Renewable Resources:
  These occur over a very long geological time. Once exhausted, they take millions of years to form again.
  Example: Coal, petroleum, natural gas, minerals.

(c) On the basis of Ownership

• Individual Resources: Owned by private individuals.
  Example: A farmer’s land, house, well, plantation, etc.
• Community Owned Resources: Resources which are accessible to all members of the community.
  Example: Public parks, picnic spots, village ponds, playgrounds.
• National Resources: Resources which belong to the nation. The country has legal powers over them.
  Example: Roads, canals, railways, minerals, forests, rivers within the country.
• International Resources: Resources beyond the exclusive economic zone of any country. International institutions have control over them.
  Example: Open oceans beyond 200 nautical miles.

(d) On the basis of Status of Development

• Potential Resources: Resources which are found in a region, but not yet fully utilised.
  Example: Wind and solar energy in Rajasthan and Gujarat.
• Developed Resources: Resources which are surveyed, quantified and used using technology and economic feasibility.
• Stock: Resources whose quantity is known, but we do not have the technology to use them.
  Example: Hydrogen and oxygen present in water which can be a source of energy.
• Reserves: A part of stock which can be used in the future with existing technology.
  Example: Forests, river water, groundwater, etc.

2. Development of Resources

Resource development means using resources to satisfy human needs, improve the quality of life, and maintain a balance with nature. However, overuse, misuse and unplanned use of resources create problems.

Indiscriminate use of resources has led to:

• Depletion of resources for future generations
• Unequal distribution of resources between rich and poor regions and people
• Environmental problems like pollution, land degradation, global warming, etc.

Therefore, resource development must be based on the idea of sustainable development.

2.1 Sustainable Development

Sustainable development means development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Main features of sustainable development:

• Using resources judiciously and efficiently
• Checking wastage and overuse of resources
• Balancing economic growth with environmental protection
• Ensuring social justice and equity in resource distribution

3. Resource Planning

Resource planning refers to the skillful, planned and judicious use of resources to reduce regional imbalances and ensure sustainable development. India has a highly varied availability of resources – some regions are rich in certain resources while others are poor.

3.1 Why Resource Planning is Necessary in India?

• Resources are unevenly distributed over the country.
• Some regions have high concentration of resources, others have very few.
• There is a danger of overexploitation of resources in some areas.
• To ensure balanced regional development and reduce disparities.
• To support sustainable economic growth and environmental protection.

3.2 Steps in Resource Planning in India

Resource planning in India broadly involves the following stages:

1. Identification and Inventory of Resources
   • Surveying, mapping and measuring the quantity and quality of resources.
   • Using technologies like remote sensing, GIS, etc.
2. Planning Structure
   • Designing a plan for resource use that matches the needs and technology level.
   • Developing strategies for exploitation and conservation.
3. Matching Resource Development Plan with National Development Goals
   • Implementing plans through policies, programmes and administrative machinery.
   • Periodic review and modification as per changing needs.

4. Conservation of Resources

Resource conservation means using resources carefully so that they can be saved for the future. Many thinkers and leaders have emphasised conservation, including Mahatma Gandhi, who believed that “there is enough for everybody’s need but not for anybody’s greed”.

Methods of conserving resources:

• Using resources judiciously and avoiding wastage
• Recycling and reuse of materials
• Adopting renewable sources of energy like solar, wind, hydel
• Protecting forests, soil, water and wildlife
• Creating awareness through education and laws

5. Land Resources

Land is a very important natural resource. It supports natural vegetation, wildlife, human life, economic activities, transport and communication systems.

India has a total geographical area of about 3.28 million sq. km. However, land resources are under great pressure due to a high population, growing demands, and competing uses.

5.1 Land Utilization

Land in India is used for different purposes. Land use can be grouped into the following categories:

• Forest area
• Land not available for cultivation (barren and unculturable land, land put to non-agricultural uses)
• Other uncultivated land (permanent pastures, grazing land, miscellaneous tree crops)
• Fallow land (current fallow and other than current fallow)
• Net sown area (land under actual cultivation)

5.2 Land Use Pattern in India

Land use pattern in India depends on:

• Physical factors – topography, climate, soil
• Human factors – population density, technology, culture, traditions

Key features of land use pattern:

• Net sown area is high in the plains (e.g., Indo-Gangetic plains).
• Forests cover a larger area in hilly and mountainous regions.
• Rajasthan, Gujarat have large portions of barren and unculturable land.
• Urbanisation and industrialisation have increased land under non-agricultural uses.

6. Land Degradation and Conservation Measures

Land degradation means a decline in the quality and productivity of land. It is a serious problem in many parts of India.

6.1 Causes of Land Degradation

• Deforestation – cutting down of trees leading to soil erosion.
• Overgrazing by animals, especially in arid and semi-arid regions.
• Mining activities – open cast mining leaves large scars on the land surface.
• Over-irrigation – leads to waterlogging and salinisation, especially in Punjab, Haryana and western Uttar Pradesh.
• Industrial waste – dumping of wastes and chemicals on land.

6.2 Measures to Conserve and Protect Land

• Afforestation and proper management of forests.
• Controlled grazing and regulated use of pastures.
• Reclamation of degraded land through land leveling, contour bunding and terracing.
• Checking mining activities, proper disposal of industrial and urban waste.
• Adopting scientific irrigation methods to avoid waterlogging and salinisation.

7. Soil as a Resource

Soil is the most important renewable natural resource. It is the uppermost layer of the earth’s crust and a medium for plant growth. Soil formation (pedogenesis) is a long and complex process influenced by:

• Parent rock
• Climate
• Relief (topography)
• Flora and fauna
• Time

7.1 Classification of Soils in India

Major soil types found in India as per NCERT are:

• Alluvial Soil
  • Formed by deposition of alluvium by rivers.
  • Found in northern plains and river valleys; also in coastal plains.
  • Very fertile; ideal for growing rice, wheat, sugarcane, pulses, oilseeds, etc.
  • Newer alluvium – khadar; older alluvium – bangar.
• Black Soil (Regur Soil)
  • Formed from volcanic rocks; found in Deccan plateau (Maharashtra, MP, Gujarat, Andhra Pradesh, etc.).
  • High clay content; retains moisture.
  • Ideal for cotton cultivation; also suitable for sugarcane, wheat, jowar, etc.
• Red and Yellow Soils
  • Formed from crystalline igneous rocks.
  • Found in parts of Odisha, Chhattisgarh, southern Karnataka, Tamil Nadu and some other regions.
  • Red colour due to presence of iron; appears yellow when hydrated.
• Laterite Soil
  • Developed in areas with high temperature and heavy rainfall.
  • Found in Karnataka, Kerala, Tamil Nadu, Madhya Pradesh and hilly areas of Odisha and Assam.
  • Poor in organic matter; not very fertile but suitable for crops like tea, coffee, cashew with proper manuring.
• Arid (Desert) Soil
  • Found in Rajasthan, Gujarat and dry regions.
  • Sandy in texture, saline in nature.
  • With irrigation, can be used to grow crops like wheat, cotton, etc.
• Forest and Mountain Soils
  • Found in hilly and mountainous areas.
  • Loamy and silty in valley sides; coarse and rocky on slopes.
  • Support forests and some types of cultivation.

8. Soil Erosion and Soil Conservation

Soil erosion is the removal of top fertile soil layer by agents like wind and water. It reduces soil fertility and threatens agriculture.

8.1 Causes of Soil Erosion

• Deforestation (cutting down of trees)
• Overgrazing by animals
• Improper farming practices (up and down the slope ploughing)
• Heavy rainfall and floods
• Strong winds in arid and semi-arid regions

Common forms of soil erosion:

• Sheet erosion: Uniform removal of soil in thin layers by rain water.
• Rill and gully erosion: Water creates small channels (rills) and deep cuts (gullies), especially in Chambal valley.
• Wind erosion: Wind blows away loose, sandy soil in dry regions.

8.2 Methods of Soil Conservation

To protect soil and maintain its fertility, the following methods are used:

• Contour Ploughing: Ploughing along the contour lines to slow down the flow of water.
• Terrace Farming: Making terraces on steep slopes to reduce surface run-off and soil loss.
• Strip Cropping: Growing crops in alternate strips to break the force of wind and water.
• Planting Shelter Belts: Rows of trees planted to reduce wind speed and protect soil in dry regions.
• Afforestation: Planting more trees, protecting forest cover to bind the soil.
• Controlled Grazing: Regulating the movement and number of animals in grazing areas.

9. Quick Revision Points (Exam-Oriented)

• Resources are anything available in the environment which can satisfy human needs, is technologically accessible, economically feasible, and culturally acceptable.
• On the basis of exhaustibility, resources are renewable and non-renewable.
• Sustainable development links resource use with the needs of future generations.
• Resource planning is essential in India because of unequal distribution of resources.
• Three main steps of resource planning: identification of resources, planning structure, and matching with national development plans.
• Major causes of land degradation: deforestation, overgrazing, mining, over-irrigation.
• Soil is a renewable resource; main factors for soil formation: parent rock, climate, relief, flora/fauna, time.
• Know at least two characteristics and crops for each major soil type.
• Soil conservation methods are frequently asked in exams – remember contour ploughing, terrace farming, strip cropping, shelter belts and afforestation.
