Chapter Contents
Topic 1: Resources and Their Classification
Understand what makes something a resource and how resources are classified.
What Is a Resource?
A resource is anything available in the environment that can satisfy human needs, provided it is technologically accessible, economically feasible and culturally acceptable. Human knowledge, skills, technology and institutions influence how resources are identified and used.
Classification of Resources
| Basis | Types | Explanation and Examples |
|---|---|---|
| Origin | Biotic and Abiotic | Biotic resources have life or come from the biosphere, such as plants and animals. Abiotic resources are non-living, such as rocks and metals. |
| Exhaustibility | Renewable and Non-renewable | Renewable resources can be replenished naturally, such as solar energy. Non-renewable resources take a very long time to form, such as coal and petroleum. |
| Ownership | Individual, Community, National and International | Examples include private fields, village grazing grounds, resources within a country's jurisdiction and resources beyond national jurisdiction. |
| Status of development | Potential, Developed, Stock and Reserves | Potential resources are not fully used; developed resources have been surveyed and their quantity and quality determined; stock cannot be used fully with available technology; reserves can be used with existing technology but are saved for future use. |
Important Things to Remember
- Resources are classified on four major bases: origin, exhaustibility, ownership and status of development.
- Biotic resources are associated with living organisms; abiotic resources are non-living.
- Renewable does not mean unlimited. Resources can still be depleted if used carelessly.
- Stock: available materials that cannot be used fully because suitable technology is lacking.
- Reserves: resources that can be used with existing technology but are conserved for future use.

Topic 2: Development and Conservation of Resources
Why uncontrolled resource use creates problems and why sustainable development matters.
Resources are essential for economic development and human well-being. However, indiscriminate exploitation can lead to depletion, environmental damage and unequal access to resources. Sustainable development promotes responsible use while protecting the interests of future generations.
Problems Caused by Resource Exploitation
- Depletion of resources to satisfy the needs of a few individuals.
- Accumulation of resources in the hands of a small section of society, increasing inequality.
- Environmental problems such as pollution, global warming, land degradation and ecological imbalance.
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.
Rio Earth Summit and Agenda 21
The United Nations Conference on Environment and Development was held at Rio de Janeiro, Brazil, in 1992. It highlighted the need to combine environmental protection with development. Agenda 21 was an action plan intended to promote sustainable development globally, including through local action.
Important Things to Remember
- Uncontrolled exploitation can deplete resources and damage the environment.
- Resource inequality can lead to unequal access to opportunities and benefits.
- Sustainable development considers both present and future generations.
- Rio Earth Summit: 1992.
- Agenda 21: an action plan for sustainable development.

Topic 3: Resource Planning in India
Understand why resources must be identified, assessed and used according to regional needs.
Resource planning is important because resources are unevenly distributed across regions. Some areas may have abundant water but limited minerals, while others may possess mineral resources but face water scarcity. Planning helps ensure judicious use and supports balanced development.
Why Is Resource Planning Necessary?
- Resources are unevenly distributed across India.
- Unplanned use can lead to depletion and environmental damage.
- Planning helps coordinate the use of resources with development priorities.
- It can reduce regional imbalances and encourage conservation.
Major Stages of Resource Planning
- Identification and inventory: Surveying resources, mapping them and estimating their quantity and quality.
- Planning structure: Developing suitable planning methods, technology, skills and institutions to use resources effectively.
- Integration: Coordinating resource development with overall national and regional development plans.
Important Things to Remember
- Resource planning is necessary because resources are unevenly distributed.
- Resource planning involves identification, suitable planning structures and integration with development plans.
- Planning supports judicious use, conservation and balanced regional development.

Topic 4: Land Resources and Land Use
Learn about land as a resource, its uses and factors affecting land use.
Land is an important natural resource. It supports natural vegetation, wildlife, agriculture, human settlements, transport, industries and other economic activities. Since land is limited, it needs to be managed carefully.
Factors Affecting Land Use
Topography, climate and soil type influence the suitability of land for different uses.
Population density, technology, culture and economic activities affect land-use patterns.
Major Categories of Land Use
- Forests.
- Land not available for cultivation, including barren land and land used for non-agricultural purposes.
- Other uncultivated land, including permanent pastures and grazing land.
- Fallow land, which is left uncultivated for a period.
- Net sown area, on which crops are sown and harvested.
Important Things to Remember
- Land is a finite resource and supports many human and natural activities.
- Physical and human factors influence land use.
- Topography, climate and soil are important physical factors.
- Net sown area is the area sown with crops; gross cropped area includes repeated cropping.
- Land-use data helps in planning and managing land resources.

Topic 5: Land Degradation and Conservation
Understand the causes of land degradation and measures to prevent it.
Land degradation is the decline in the quality and productive capacity of land. It can result from human activities and natural processes. Degraded land may become less suitable for agriculture, vegetation and other uses.
Major Causes of Land Degradation
- Deforestation: Removal of vegetation exposes soil to erosion.
- Overgrazing: Excessive grazing reduces vegetation cover.
- Mining and quarrying: Excavation disturbs the land surface and may leave waste materials.
- Over-irrigation: In some areas it can cause waterlogging and increase salinity or alkalinity.
- Industrial waste: Untreated effluents and waste can contaminate land and soil.
Measures to Control Land Degradation
- Afforestation and restoration of vegetation cover.
- Regulation of grazing and better pasture management.
- Scientific management and reclamation of mined areas.
- Proper irrigation and drainage to prevent waterlogging.
- Treatment and safe disposal of industrial waste.
- Soil conservation and responsible land-use planning.
Important Things to Remember
- Land degradation reduces land quality and productive capacity.
- Overgrazing, mining, deforestation, over-irrigation and industrial waste are important causes.
- Different causes require different conservation methods.
- Vegetation cover helps protect soil from erosion.
- Proper irrigation and drainage can reduce waterlogging and salinity problems.

Topic 6: Major Soil Types of India
Revise the characteristics, distribution and agricultural importance of major Indian soils.
Soil is an important natural resource that supports plant growth and agriculture. Soil formation is influenced by parent rock, climate, relief, vegetation, other organisms and time. Different regions have different soil characteristics.
Comparison of Major Soil Types
| Soil Type | Characteristics | Distribution / Importance |
|---|---|---|
| Alluvial Soil | Deposited mainly by rivers; generally fertile and suitable for many crops. | Large parts of the northern plains and river valleys, as well as coastal and deltaic areas. |
| Black Soil | Generally clayey and has high moisture-retention capacity; develops cracks during dry periods. | Common in parts of the Deccan Plateau; especially associated with cotton cultivation. |
| Red and Yellow Soil | Red colour is largely due to iron compounds; yellow colour may develop under hydrated conditions. | Found in parts of eastern and southern India, including areas of crystalline rocks. |
| Laterite Soil | Develops under conditions of high temperature and heavy rainfall with intense leaching. | Found in parts of the Western and Eastern Ghats and other high-rainfall regions; fertility may require appropriate soil management. |
| Arid Soil | Often sandy, may be saline and usually has low humus in dry areas. | Found mainly in arid and semi-arid regions, especially western Rajasthan. |
| Forest and Mountain Soil | Properties vary with altitude, slope, climate and vegetation. | Found in hilly and mountainous areas; soil may be thin on steep slopes and more developed in valleys. |
Alluvial Soil: Khadar and Bangar
Newer alluvial deposits, often renewed by river floods and generally finer in texture.
Older alluvial deposits, generally found on higher terraces and often containing calcareous concretions called kankar.
Important Things to Remember
- Alluvial soil is widely associated with river plains and is generally fertile.
- Black soil retains moisture well and is associated with cotton cultivation.
- Iron compounds contribute to the red colour of red soil.
- Laterite soil develops through intense leaching under high rainfall and temperature.
- Arid soil is common in dry regions.
- Khadar is newer alluvium; bangar is older alluvium.

Topic 7: Soil Erosion and Soil Conservation
Learn how topsoil is lost and which methods help protect it.
Soil erosion is the removal of the upper fertile layer of soil by agents such as running water and wind. Erosion can reduce soil fertility, lower agricultural productivity and contribute to sedimentation in water bodies.
Types of Soil Erosion
Running water cuts deep channels into the soil. These channels can grow into ravines.
Water removes a thin, relatively uniform layer of topsoil over a wider area.
Strong winds lift and carry away loose soil, especially where vegetation cover is limited.
Methods of Soil Conservation
- Contour ploughing: Ploughing along contour lines slows water flowing downhill.
- Terrace farming: Steps are made on slopes to reduce runoff speed and soil loss.
- Strip cropping: Crops are grown in strips to reduce the impact of wind and water erosion.
- Shelter belts: Rows of trees reduce wind speed and help protect soil.
- Afforestation: Plant roots help hold soil and vegetation reduces the direct impact of rain.
- Controlled grazing: Maintaining plant cover helps prevent soil exposure.
Important Things to Remember
- Soil erosion removes fertile topsoil.
- Gully erosion creates deep channels; sheet erosion removes a thin layer over a wide area.
- Contour ploughing and terrace farming are useful on suitable slopes.
- Shelter belts reduce wind speed.
- Afforestation and vegetation restoration help protect the soil.
