Question 3.
Can you name some resource rich but economically backward regions and some resource poor but economically developed regions ? Give reasons for such a situation.
Answer:
The states of Jharkhand, Chhattisgarh. Madhya Pradesh, Arunachal Pradesh and Rajasthan are rich in minerals and coal deposits but lack in infrastructural developments. While Punjab, Haryana, Gujarat, Maharashtra have less resources, but they are economically developed. The major reason of this, there is lack of appropriate technological development, basic infrasturcture and institutional change in the backward states while there is multiplicity of technological development and institutional change in the developed states.

(iii) What steps can be taken to control soil erosion in the hilly areas ?
Answer:
The following steps should be taken to control soil erosion in the hilly areas:
1. In hilly areas, land should be cultivated by terrace farming.
2. Dense plantation should be done on slopes.
3. The contour ploughing should be done on slope land.

(iv) What are the biotic and abiotic resources ? Give some examples.
Or
Differentiate between biotic and Abiotic resources.
Answer:
(i) All biotic resources are obtained from the biosphere and have life (e.g. forest, live stock, human beings etc.) All abiotic resources are composed of non-living things (e.g. rocks, water etc).

3. Answer the following questions in about 120 words.

(i) Explain land use pattern in India and why has the land under forest not increased much since 1960-61?
Answer:
Land Use Pattern in India: The use of land is determined both by physical factors such as topography, climate, soil types as well as human factors such as population density, technological capability and culture and traditions etc.

The facts of land pattern in India as per data for the year 2014-15 are as follows:
1. Land pattern in India is not balanced.

1.      There is 23.3% regions are available under forest.

2.      The land under permanent pasture is also low (3.3%).

3.      Maximum use of land is 45.5% under the net sown area and the minimum use is 1% under the diverse trees, tree crops and forest.

2. In our country the land pattern is not balanced at National, state and local level.
Major reasons for not increasing the land under forest since ‘1960-61 :
In 2014-15 only 5.19% forest has been increased in comparison to 1960-61. Rapid population growth is the main reason for not increasing the land under forest in India. Forests are being cut for the economic profit. Trees have been cut for the development of different industries, agricultural work and habitat. That’s . whv forests have not been increased much since 1960-61.

(ii) How have technical and economic development led to more consumption of’ resources?
Answer:

1.      Technological development has converted the subsistence agriculture to commercial agriculture and this has led to the over utilization of soil.

2.      Technological development has led to industrialisation which has increased the use of natural resources.

3.      Economic development has led to urbanisation and modernization which demands more resources.

4.      Technological development has also improved the process of mining. Project/Activity
