Due to the availability of properly developed infrastructure it is industrially rich as well as most of the head offices of various government organizations are also situated here. Q. 3: Why Is conservation of resources Important? Mans: Irrational consumption and over-utilization of resources lead to socio-economic and environmental problems.
If natural resources are not used judiciously then, it will cause a stagnation of development after a point of time.Exploiting resources unethically will ultimately undo the development that a country may have achieved as in future those resources will not be available for further progress. Q. 4: The pattern of net sown area varies greatly from one state to another. It Is over 80% of the total area In Punjab and Harlan and less than 10% In Raunchy Pradesh, Mozart, net sown area in these states.
Mans: Reasons for the low proportion of net sown area in Raunchy Pradesh, Mozart, Maniple and Madman Nicolai Islands are as follows: 1. Mostly tribal group lives in this region.Even today they practice shifting cultivation.
2. These states are covered by dense tropical forests. 3. These states receive very heavy and a large amount of rainfall. 4. The topography ND soil types are not favorable for the cultivation.
5. These states are still considered as backward where the farmers or peasants are economically poor and do not have access to technological resources. NICER Textbook Exercise Questions Q. L: Multiple choice questions: (I) Which one of the following types of resources is iron ore? A.

Q. 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 from 1960-61? It) How have technical and economic development led to more consumption of resources? Mans: (I) Land-use pattern in India is a dynamic concept. It changes over space and time.Land-use pattern in India is as follows: 1. About 46% area is the net sown area in the country. 2. Forests occupy about 22% of the reporting area.
3. The cultivable waste land accounts for nearly 5% of the area. 4. The fallow land covers about 8% of the total area. 5. Permanent pastures and tree crops cover only 5%.
6. The land not available for cultivation is nearly 14% of the total area. The factors which determine land use are two fold: a) Physical – climate, soil and relief. (b) Human – culture, tradition and technology. The main causes for the change in Land-use pattern are – 1.Growing human population 2. Arbitration 3. Industrialization, This then varies from state to state also.
The above mentioned factors are also responsible for the decrease in land under forest which is around 19% I. E. 14% away from 33% norm of NUN body on environment protection but a slight improvement after 1960-61 I.
E. Of 22% of the total geographical area. (it) Technical and economic development have led to more consumption of resources on account of arioso factors such as: 1 . Technological development provides sophisticated equipments.As a result, production increases ultimately leading to consumption of more resources.
2. Technological development also leads to economic development. When the economic condition of a country rises, the needs of people also rise. It again results into more consumption of resources.
3. Economic development provides favorable environment for the development of latest technologies. It helps to make or convert various materials found around us into resources. Finally, it results into the consumption of new available resources too.
