ON THE BASIS OF STATUS OF DEVELOPMENT:

DEVELOPMENT OF RESOURCES

It is the process of developing the resources in order to make them useful for satisfying human wants. Some resources cannot be used directly. They have to be processed to make them useful for satisfying our wants. Ex: Land has to be cleared and ploughed for growing crops. Water has to be taken to the field to irrigate.

a. Many resources got depleted. Ex: Forest b. Resources got accumulated in the hands of

few people. The society is divided into rich and poor.

c. Global warming, ozone layer depletion, environmental degradation are other problems.

PROBLEMS CREATED BY INDISCRIMINATE USE OF RESOURCE BY MAN

The economic development which does not damage the environment and at the same time takes care of the needs of the future generations is called sustainable development

Sustainable Development is important because:

1) Many of the resources are non-renewable and exhaustible. Over exploitation of these resources will affect the needs of our future generations.

2) Environmental pollution has become a major threat to the survival of human beings

SUSTAINABLE ECONOMIC DEVELOPMENT

Resource planning is a technique or skill of proper utilization of resources.

STAGES OF RESOURCE PLANNING a) IDENTIFICATION AND LISTING OF RESOURCES Surveying, mapping and the

measurement of the qualities and the quantities of the resources are the important activities undertaken at this stage.

b) PLANNING FOR EXPLOITATION Develop a planning structure with

suitable technology, skill and institutional setup.

c) MATCH RESOURCE DEVELOPMENT PLANS WITH NATIONAL DEVELOPMENT PLANS.

RESOURCE PLANNING

It is necessary for the balanced development of India. 1) Some regions of India are rich in certain resources

and poor in some other resources. Ex: Rajasthan is poor in water resources but

rich in solar and wind energy. 2) Some regions are self sufficient while other regions

are very poor in important resources. Ex: Madhya Pradesh is rich in many resources but Ladakh is poor in resources.

3) Wastage of resources can be avoided by planning.

4) Environmental pollution can be reduced. 5) Over exploitation of resources can be avoided. 

IMPORTANCE OF RESOURCE PLANNING

Planned use of resources in order to meet the present needs and to store a part for the future generations is called resource conservation.

It is necessary because 1) Many resources are non-

renewable and exhaustible. If we conserve them we can use them for a longer period of time.

2) Conservation of resources helps us to reduce wastage. It will help in economic progress.

3) Resource conservation helps us to protect the environment.

RESOURCE CONSERVATION

According to Gandhi ji, “There is enough for everybody’s need and not for anybody’s greed.

Greedy and selfish individuals and the exploitative nature of modern technology are the root cause for resource depletion.

He was against mass production and wanted to replace it with production by masses.

IDEAS OF GANDHI JI ABOUT THE CONSERVATION OF RESOURCES.

Land is the habitat of man. All the economic activities are performed on

land. The soil cover on the land is essential for

plant growth. So land is necessary for agriculture. Land is used to setup industrial units.

Roads and railways are built on the land. Commercial activities also require land. Natural vegetation and wild life are supported by land.

LAND AS A RESOURCE.

PLAINS - 43%MOUNTAINS - 30%PLATEAUES - 27% 43% of India’s land area is plain. This region

is good for agriculture and industry. 30% of the land area is mountains. This region is rich in water resources. Plateaus occupy 27% of the land area. This region is rich in minerals, fossil fuels and forest.

LAND UNDER DIFFERENT RELIEF FEATURES IN INDIA

Total land area of India is 3.28 million square km.

i). 43.41% of the land area is net sown area. ii). Forests occupy 22.57% of land area. iii). 6.29% of the land is waste land. iv). 7.92% of the land is used for non

agricultural purposes. v). 3.45% of the land is pastoral land. vi). 1.10% of the land is tree crops. vii). 4.41% of the land is cultivable waste. viii). 3.82% of the land is fallow other than

current fallow. ix) 7.03% of the land is current fallow.

LAND USE PATTERN IN INDIA

i). Large scale soil erosion caused by running water and wind.

ii). Dumping of waste materials from mining centers and industrial units.

iii). Over irrigation leads to increase in salinity and alkalinity in the soil.

iv). Over grazing by animals and deforestation by man.

v). Waste water from the industrial units pollute the lands.

vii).Mineral processing like grinding of limestone for cement industry and calcite and soap stone for ceramic industry creates a lot of dust. This dust is deposited in the neighbouring land.

CAUSES OF LAND DEGRADATION

i). Some industries dump solid waste which contains harmful chemicals on the neighboring lands.

ii ). Some industries discharge waste water to the fields.

iii). Mineral processing like grinding of limestone for cement industries and calcite and soap stone for ceramic industry creates a lot of dust. This dust is deposited in the neighboring land.

iv). Clearing of forest for industrial purpose also cause degradation.

HOW DO INDUSTRIES CAUSE LAND DEGRADATION ?

i). Soil erosion can be prevented by ending deforestation, controlling grazing, encouraging afforestation and practicing terrace farming in hilly areas.

ii). Preparation of shelter belts of plants and stabilizing of sand dunes by growing thorny bushes will help to prevent land degradation in deserts.

iii). Mining activities should be controlled. New technology which reduces wastage can be adopted.

iv). Industrial waste should be chemically treated to remove the harmful substances.

v). Urban waste should be used for the production of bio-gas and bio-manure.

vi). Over irrigation should be stopped and new method of irrigation should be followed

LAND CONSERVATION MEASURES

130 million hectares of land is degraded in India.

56% of it is water eroded area.

28% of it is forest degraded area.

6% of it is saline and alkaline deposits.10% of it is wind eroded area.

DEGRADED LAND IN INDIA.

SOIL

The upper most layer of the earth’s crust which is loose , broken and useful for plants is called soil.

 Soil consists of mineral matter such as sand and clay

and Organic matter such as humus, bacteria and earth worms.

Soil is formed mainly due to the process of weathering. As a result of weathering a layer of loose rock materials is formed on the land surface. If this layer remains undisturbed for a long period of time, chemical, physical and organic changes take place in it. These changes lead to the formation of soil.

SOIL

1) Climate: Climate decides the rate of weathering and the

type of vegetation. 2) Topography: Topography of the land decides the accumulation

of soil. 3) Nature of parent rock: It decides compositions and texture of the

soil. 4)Vegetation: Vegetation decides the amount of humus

available in the soil.

FACTORS WHICH INFLUENCE (OR) GOVERN THE SOIL FORMATION PROCESS

i). Man depends on the soil directly or indirectly for his food.

ii). Agriculture can be practiced only if soils are available.

iii). Man gets the materials needed for shelter and clothing directly (or) indirectly from the soil.

iv). Soils are essential for the growth of forests.

SOILS ARE OUR PRIME RESOURCES

ALLUVIAL SOILS

i). Alluvial soil is the most fertile and wide spread soil found in India.

ii). It is formed due to the deposition of fine silt called alluvium by the rivers.

iii). It is found in the northern plains, Gujarat plains and the coastal plains.

iv). It consists of sand, silt and clay. v). It is divided into khadar and Bangar [new

alluvium and old alluvium] It contains soil nutrients such as potash, phosphoric acid and lime. So, it is fertile and good for the growth of sugarcane, rice, wheat and pulses.

ALLUVIAL SOILS

BLACK SOILS

Regur soils are called black cotton soils because they are black in colour and are very good for cotton cultivation.

It is made up of extremely fine clayey materials. It has the capacity to hold moisture for a long

time. These soils develop deep cracks in summer. This helps in the aeration of the soil.

This soil is sticky. It is mainly found in the Deccan Trap region of Maharashtra, Gujarat, Madhya Pradesh and Chattisgarh.

It is formed due to the weathering of volcanic rocks. It is very rich in potash, calcium carbonate, magnesium and lime. It is poor in phosphoric content.

BLACK SOILS

RED SOILS

Red soils are formed due to the weathering of crystalline igneous rocks under low rainfall conditions.

It is red in colour because of the presence of iron in it.

It is found in Tamilnadu , Karnataka, Andhra Pradesh, Orissa, Chhattisgarh and Jharkhand.

RED SOILS

LATERITE SOILS

The word laterite originated from the Latin word later which means brick.

Laterite soil is formed due to intense leaching caused by tropical rainfall.

Humus content is less because the micro-organisms get destroyed due to high temperature.

This soil can be cultivated by using manure and fertilizers. It is good for the cultivation of tea, coffee and cashew nut. It is found in Kerala, Karnataka, Tamilnadu, Madhya Pradesh, Orissa and Assam.

LATERITE SOIL

ARID (DESERT) SOILS

Arid soils are red or brown in colour. They are sandy and saline.

Humus and moisture contents are very less. They can be cultivated after irrigation.

Kankar layer in the soil prevent the water from seeping under ground.

ARID SOILS

FOREST SOILS

Forest soils are found in hilly and mountainous regions.

They are loamy and silty in valleys and coarse in the upper slopes.

In Himalayas they suffer denudation and are acidic with low humus content.

The soils found in the lower slopes of the valley are fertile.

FOREST SOILS

Soil Erosion

Removal of top soil from one place to another by natural agencies is called soil erosion.

It is caused by running water and wind. Deforestation, over grazing and

unscientific agricultural practices are responsible for large scale soil erosion.

SOIL EROSION

GULLY EROSION

The rain water when moves down on an uneven land scoops away the soil and form deep channels called gullies. This type of erosion is called gully erosion.

A land which is broken into many small parts by the gullies is called bad land. A bad land is unfit for cultivation and for other economic activities.

GULLY EROSION

Some times water flows as a sheet over large areas down a slope. The water takes away the top soil. This type of erosion is called sheet erosion.

SHEET EROSION

i). Contour ploughing reduces the flow of water and prevent soil erosion.

ii). In hilly areas terraced farming should be followed.

iii). Strip farming helps to reduces the force of winds.

iv). Shelter belts of plants around the fields reduce soil erosion.

v). A forestation should be practiced on a large scale and deforestation should be stopped.

vi).Over grazing by animals should be avoided.
