CBSE Class 10 Social Science Geography Revision Notes Chapter 1 on Resources and Development

A resource is anything available in the environment that can be used to satisfy human needs. It must be technologically accessible, economically feasible and culturally acceptable.

Resources are not simply free gifts of nature. Human beings use knowledge, skills, technology and institutions to transform materials into useful resources.

For example, water, soil, minerals, forests and land become resources when people know how to use them without damaging their future availability.

Important Topics in CBSE Class 10 Geography Chapter 1 Notes

Class 10 Geography Chapter 1 Notes focus on resources, land and soil. These three ideas are connected because land supports most human activities, while soil supports agriculture and living organisms.

This chapter is best revised through definitions, examples, map-based understanding and cause-effect explanations.

Resources and Development Class 10 Notes: Meaning of Resources

Resources are linked with three conditions:

• Technology: People must know how to use the material.
• Economic feasibility: Using it should be practical and affordable.
• Cultural acceptability: Society should accept its use.

A material may exist in nature, but it becomes a resource only when humans can use it. This is why human beings are also considered an important part of resources.

Nature, Technology and Institutions

Resources develop through an interdependent relationship between nature, technology and institutions.

Nature provides materials. Technology helps humans transform these materials. Institutions organise this process and support development.

For example, minerals inside the earth become useful only when people can identify, mine, process and use them through suitable technology and systems.

Classification of Resources in Class 10 Social Science Geography Chapter 1 Resources and Development

Resources are classified on different bases. This classification helps students understand where resources come from, how long they last, who owns them and how developed they are.

Types of Resources Based on Origin

Biotic resources have life or come from living organisms. Abiotic resources are physical and non-living.

Types of Resources Based on Exhaustibility

Renewable resources can be renewed or reproduced by physical, chemical or mechanical processes. Solar energy, wind energy, forests and water are examples.

Non-renewable resources take millions of years to form. Coal, petroleum and natural gas are examples. Once these are used too quickly, they cannot be replaced within a short human time period.

Types of Resources Based on Ownership

National resources include land, water, minerals and forests within the country’s political boundary. International resources need regulation by international institutions.

Types of Resources Based on Status of Development

Potential resources are available in a region but have not been fully used. Wind and solar energy in Rajasthan and Gujarat are examples.

Developed resources have been surveyed, and their quantity and quality are known. They are ready for use.

Stock refers to materials that can satisfy human needs but cannot be used because suitable technology is not available.

Reserves are part of stock that can be used with present technology but are saved for future use.

Development of Resources in Geography Class 10 Chapter 1 Notes

Resources are necessary for human survival and quality of life. However, indiscriminate use of resources creates serious problems.

Overuse of resources can lead to depletion. When resources are controlled by only a few people, society gets divided into rich and poor. Excessive exploitation also causes ecological crises such as global warming, ozone layer depletion, pollution and land degradation.

Development of resources must therefore be balanced and planned. Resource use should support present needs without damaging environmental stability.

Sustainable Development in Resources and Development Class 10 Notes

Sustainable development means development that takes place without damaging the environment. It also means that present development should not compromise the needs of future generations.

This idea is important because development cannot continue if resources are exhausted. For example, if groundwater is used faster than it is recharged, future generations may face water scarcity.

Sustainable development connects resource use with conservation. It asks whether economic growth is happening in a way that protects land, water, forests, minerals and living organisms.

Rio de Janeiro Earth Summit and Agenda 21 in Class 10 Geography Chapter 1 Notes

The first International Earth Summit was held in June 1992 at Rio de Janeiro in Brazil. More than 100 heads of states met to discuss environmental protection and socio-economic development.

The leaders signed important agreements related to global climatic change and biological diversity. They also endorsed Forest Principles and adopted Agenda 21.

Agenda 21

Agenda 21 is a declaration signed at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992.

It aims to achieve global sustainable development. Its goal is to fight environmental damage, poverty and disease through global cooperation. One major objective is that every local government should create its own local Agenda 21.

Resource Planning in India in CBSE Class 10 Social Science Geography Revision Notes Chapter 1

Resource planning means using resources carefully and judiciously. It is especially important in India because resources are unevenly distributed.

Some regions are rich in minerals but lack other resources. Some areas have water resources but lack infrastructure. Some regions have solar and wind energy but lack water.

Examples from NCERT:

• Jharkhand, Chhattisgarh and Madhya Pradesh are rich in minerals and coal.
• Arunachal Pradesh has abundant water resources but lacks infrastructure.
• Rajasthan has solar and wind energy but lacks water.
• Ladakh has rich cultural heritage but lacks water, infrastructure and some minerals.

Balanced planning is needed at local, regional, state and national levels.

Steps in Resource Planning in India

Resource planning is a complex process. It involves identification, planning and matching resource plans with national goals.

First, resources are identified and inventoried through surveys, mapping and estimation. Then, a planning structure is created with suitable technology, skills and institutions. Finally, resource development plans are matched with national development plans.

India began resource planning from the First Five Year Plan after Independence.

Conservation of Resources in Resources and Development Class 10 Notes

Resource conservation means careful use and protection of resources. It is necessary because irrational consumption and overuse create social, economic and environmental problems.

Mahatma Gandhi linked resource depletion with greed and exploitative technology. His idea was that nature has enough for need, but not for greed.

At the global level, resource conservation was discussed by the Club of Rome in 1968. The Brundtland Commission Report of 1987 introduced the concept of sustainable development and later influenced global action at the Rio Earth Summit.

Conservation is not about stopping development. It is about using resources in a way that development can continue in the future.

Land Resources in Class 10 Social Science Geography Chapter 1 Resources and Development

Land is one of the most important natural resources. It supports natural vegetation, wildlife, human life, economic activities, transport and communication systems.

Land is limited, so it needs careful planning. India has different relief features: plains, mountains, plateaus and islands.

Plains are important for farming and settlements. Mountains support perennial rivers and biodiversity. Plateaus provide mineral and forest resources.

Land Utilisation in Class 10 Geography Chapter 1 Notes

Land resources are used for several purposes. These include forests, agriculture, grazing, settlements, roads, industries and other activities.

The main land-use categories are:

• Forests
• Land not available for cultivation
• Other uncultivated land excluding fallow land
• Fallow lands
• Net sown area

Important Land Use Terms

Net sown area is the physical extent of land on which crops are sown and harvested.

Gross cropped area means net sown area plus the area sown more than once in an agricultural year.

Current fallow means land left without cultivation for one or less than one agricultural year.

Culturable waste land is land left uncultivated for more than five agricultural years.

Land Use Pattern in India in Resources and Development Class 10 Notes

Land use is determined by both physical and human factors.

Physical factors include topography, climate and soil type. Human factors include population density, technology, culture and traditions.

India’s land use data is available for about 93% of the total geographical area. Some areas, especially parts of the north-east except Assam, have incomplete land use reporting. Some areas of Jammu and Kashmir occupied by Pakistan and China have also not been surveyed.

Forest area in India is lower than the desired 33% of geographical area mentioned in the National Forest Policy of 1952. Forests are important for ecological balance and for the livelihood of people living near forest areas.

Land Degradation and Conservation Measures in Class 10 Geography Chapter 1 Notes

Land degradation means the decline in the quality and productivity of land. Continuous use of land without conservation causes serious damage to society and environment.

Human activities are major causes of land degradation. Deforestation, overgrazing, mining, quarrying, over-irrigation and industrial waste all damage land.

Causes of Land Degradation in India

Mining causes land degradation in Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha. Mining sites are often abandoned after excavation, leaving deep scars.

Overgrazing is a major cause in Gujarat, Rajasthan, Madhya Pradesh and Maharashtra.

Over-irrigation in Punjab, Haryana and western Uttar Pradesh causes waterlogging and increases salinity and alkalinity in soil.

Industrial effluents have become a major source of land and water pollution in many areas.

Measures to Control Land Degradation

Afforestation can help restore degraded land. Proper management of grazing can reduce pressure on land. Shelter belts and thorny bushes help stabilise sand dunes in arid areas.

Mining activities need control. Waste lands should be managed properly. Industrial effluents should be treated before disposal to reduce land and water pollution.

Soil as a Resource in CBSE Class 10 Social Science Geography Revision Notes Chapter 1

Soil is one of the most important natural resources. It supports plant growth and different living organisms.

Soil formation is very slow. It takes millions of years to form soil up to a few centimetres in depth.

The main factors of soil formation are relief, parent rock, climate, vegetation, other forms of life and time. Running water, wind, glaciers, temperature changes and decomposers also help form soil.

Soil contains both organic materials such as humus and inorganic materials such as minerals.

Types of Soil in India in Resources and Development Class 10 Notes

India has different types of soils because it has varied landforms, climate and vegetation.

Alluvial Soil in Class 10 Geography Chapter 1 Notes

Alluvial soil is the most widespread and important soil in India. It is found in the northern plains and river valleys.

The Indus, Ganga and Brahmaputra river systems have deposited alluvial soil. It is also found in eastern coastal plains, especially in the deltas of the Mahanadi, Godavari, Krishna and Kaveri rivers.

Alluvial soil contains sand, silt and clay. It is very fertile and supports crops such as sugarcane, paddy, wheat, cereals and pulses.

Old alluvial soil is called Bangar. New alluvial soil is called Khadar. Khadar has finer particles and is more fertile than Bangar.

Black Soil in Geography Class 10 Chapter 1 Notes

Black soil is also called regur soil. It is ideal for growing cotton, so it is also known as black cotton soil.

Black soil is found in the Deccan Trap region. It covers parts of Maharashtra, Saurashtra, Malwa, Madhya Pradesh and Chhattisgarh. It also extends along the Godavari and Krishna valleys.

This soil is clayey and can hold moisture well. It is rich in calcium carbonate, magnesium, potash and lime but poor in phosphoric content. It develops deep cracks in hot weather, which helps aeration.

Red and Yellow Soil in Class 10 Geography Notes

Red soil develops on crystalline igneous rocks in areas of low rainfall. It is found in the eastern and southern parts of the Deccan Plateau.

It is also found in parts of Odisha, Chhattisgarh, the southern parts of the middle Ganga plain and along the piedmont zone of the Western Ghats.

The red colour comes from iron diffusion in crystalline and metamorphic rocks. It appears yellow when found in hydrated form.

Laterite Soil in Resources and Development Class 10 Notes

Laterite soil develops in tropical and subtropical climates with alternate wet and dry seasons. It forms due to intense leaching caused by heavy rainfall.

It is found in southern states, Western Ghats region of Maharashtra, Odisha, some parts of West Bengal and north-eastern regions.

Laterite soil is generally acidic and poor in plant nutrients. In areas with deciduous and evergreen forests, it may be rich in humus. With proper soil conservation, it can support crops such as tea, coffee and cashew nut.

Arid Soil in Class 10 Social Science Geography Chapter 1

Arid soil ranges from red to brown in colour. It is sandy in texture and saline in nature.

This soil is found in dry regions, especially western Rajasthan. It has low humus and low moisture because evaporation is high in dry climates.

The lower layers contain kankar due to increasing calcium content. After proper irrigation, arid soils can become cultivable.

Forest Soil in Class 10 Geography Chapter 1 Notes

Forest soils are found in hilly and mountainous areas with sufficient rainfall and forests.

Their texture changes with location. They are loamy and silty on valley sides and coarse-grained on upper slopes.

In snow-covered Himalayan areas, these soils are acidic and low in humus. Soils in lower valley parts, river terraces and alluvial fans are fertile.

Soil Erosion in Resources and Development Class 10 Notes

Soil erosion is the denudation of soil cover and its washing down. Soil formation and soil erosion usually happen together, but human activity can disturb this balance.

Deforestation, overgrazing, construction, mining and wrong farming methods increase soil erosion. Natural forces such as running water, wind and glaciers also cause erosion.

Types of Soil Erosion

Gully erosion occurs when running water cuts deep channels through clayey soil. The land becomes unfit for cultivation. In the Chambal basin, such lands are called ravines.

Sheet erosion occurs when water flows as a sheet over large areas down a slope and washes away the topsoil.

Wind erosion occurs when wind blows loose soil from flat or sloping land.

Wrong ploughing up and down a slope creates channels for quick water flow and increases soil erosion.

Soil Conservation in CBSE Class 10 Geography Chapter 1 Notes

Soil conservation means protecting soil from erosion and loss of fertility. It is necessary because soil takes a very long time to form.

Contour ploughing means ploughing along contour lines. It slows the flow of water down the slope.

Terrace farming means cutting steps on slopes. It is common in the western and central Himalayas and helps reduce erosion.

Strip cropping means growing strips of grass between crops. These strips reduce the force of wind.

Shelter belts are rows of trees planted to reduce wind speed. They help stabilise sand dunes in western India.
