The state’s economic development is ensured by quantitative and qualitative usage of natural resources. Forests promote tourism and that results in increase of foreign currency earning without exports.
RBSE Class 11 Economics Chapter 24 Long Answer Type Questions
Question 1.
How is the economy of a state influenced by natural resources? Explain in detail.
Answer:
Natural resources include all those resources received from nature which are present in the nearby physical environment of the human being. The form, level and development of any economy depend on the quantity of its geographical and natural resources, diversity, quality and its capability to utilize such resources. Industries get raw materials through mineral resources. Oil, coal, natural gas are the backbone of economy.
In this world, life depends largely upon natural resources. Countries like America, Britain, France, Germany etc. also depend on natural resources. In India, the progress of states like Punjab, Haryana, Gujarat, Maharashtra also depends upon such natural resources. State’s climate, land forest, water and mineral resources decide the state and course of industrial development, which foresightedly effects the employment and income of the state. The state’s economic development is ensured by quantitative and qualitative usage of resources. By proper utilization of natural resources, hitting the next pedestal of development becomes easier.
Question 2.
The economy of a state is strengthened by the development of forest and water resources. Explain.
Answer:
To make the economy of a state strong, development of forest and water resources is essential. If a state has more number of forests then this forest wealth makes the economy stronger. From forests, timber wood, fuel, grass, bamboo, honey and wax, catechu, tendu leaves, khus etc. are obtained, which increases the national income. Due to the forests, the moisture in the oxygen remains neutral, which decreases the pollution. Nothing is possible without water. When the resources will be in the exact quantity, than only agriculture can take place. India is an agriculture based economy, and agriculture can only be performed with proper water resources. Drought and famine are normal in the state due to scarcity of water.
The rain water must be collected to increase the water resources, because Rajasthan does not have any such river which can fulfill all these needs. Therefore, the state is dependent upon rain only. Productivity will be better on the availability of water resources, by which income of the state will increase. Forests also promote tourism. By this, foreign exchange is obtained even without exports, which is a good source of income for an economy. Forest and water resources can also said to be complementary to each other, because if forests are more, rainfall will be more, by which water resources will increase, and finally, the economy will strengthen by increase in both of these.
Question 3.
The minerals are the backbone of state economy. Explain.
Answer:
To make the economy of a state strong, development of mineral resources is a must . Iron, steel, cement, coal, petrol, diesel, aluminium, fertilizers etc. are beneficial just like a milestone in the state’s economy. Every mineral is used as a raw material in the industry, and on the other hand, it also increases the state’s revenue and employment level. In the mineral industry of the state, about 5 lakh people are employed either directly or indirectly. From the viewpoint of cost of production, it is at the 5th position in India.
Currently, Rajasthan is the only producer of Jasper and Wollastonite. The state ranks at number one in the country in the production of Lead, Zinc Ore, Tungston Ore, Phosphorite, Asbestos, Calsite, Bone China, Feldspar, Garnet, Silver Ore, Soapstone etc. At the prevailing rates, earning from minerals in 1991-92 was INR 511 crore, which increased to INR 21750 crore in 2013-14.
Oil, coal, natural gas are the backbone of economy. In this world, life largely depends upon various natural resources. In India, the progress of states like Punjab, Haryana, Gujarat, Maharashtra also depends upon such natural resources.
Question 4.
The economy of a state which has fertile land and water resources in adequate amount can never be weak. Give your suggestions in detail in this regard.
Answer:
The role of natural resources is very important for the development of any economy. Agriculture is the lifeline of Rajasthan’s economy. The form of crops in any area depends on source of irrigation, means of transportation, population density and nature of soil. Crop production is done while keeping in mind the status or type of soil, rain and climate. Land is used as a primary source in an economy. The area that has fertile land and where water supply is in accurate amount, the yield of crops is good there, which will help in the increment of national income. Because if the crops of any state is better than the crops of any other states, than it can be bought from different states, and thus there comes no need to import it from the other country.
Most of the people of the state are dependent upon agriculture. Due to the yielding land, they do not go towards the city. They are dependent upon agriculture for their livelihood. Companies and factories can also be established in those states which have abundant water resources. Without water resources, it is even not possible to perform agriculture, which can weaken the state’s economy. Fertile land and water resources are essential requisites for the development of a state. Due to fertile land and availability of abundant water resources, states such as Punjab and Haryana are green and their economy is also strong. While in Rajasthan, most of the part being a desert, more than 50% of the land is infertile and water resources are also less. Due to this, economy of Rajasthan is weak and only a few crops are grown here. It is clear from the above discussion, that the economy of a state strengthens by the presence of fertile land and availability of water resources.

RBSE Class 11 Economics Chapter 24 Long Answer Type Questions
Question 1.
Explain the problems and solutions of Metallic Minerals in Rajasthan.
Answer:
A variety of minerals is found in Rajasthan. Out of these, many are developed in an unreasonable way and some other minerals were left underdeveloped. Following are the problems of Metallic Minerals in Rajasthan :
- Unequal distribution of minerals :
In Southern and south-eastern parts of the state, minerals are found in enormous amount. But in northern parts, these are found in less quantity. Due to this reason, there is dissimilarity in industrial and economic development across the state. - Unplanned utilization :
In the state, utilization of minerals could not be done in a planned manner because there is scarcity of means of transport, and also in obtaining minerals from mountainous regions, mining cost is very high. - Lack of fuel and iron minerals :
There is lack of fuel and iron minerals for engineering and heavy industries. - Lack of mechanization :
Due to lack of financial resources with land miners, old methods are used in mining. - Lack of skilled and trained labourers :
Most of labourers engaged in mining industry are not only unskilled, but also uneducated. Hence, they are not able to do their work properly. - Lack of water and electricity :
There is deficiency of water. The water which is available is geological water. Also, there is lack of electricity which is responsible for non-development of mineral industries. - Most of the minerals are obtained in Rajasthan, but these are sent to other states for purification. This deteriorates their quality and their cost also increases.
- First Mineral Policy was declared in Rajasthan in 1978.
- In 1979, Rajasthan State Mineral Development Commission (RSMDC) was established. The main purpose of this was to fasten mining and marketing of minerals and development by scientific methods. Rajasthan Tungsten Development Commission Limited was formed by the suggestion of Defense Ministry of India in the form of RSMDC on 22 November, 1983 by the state government. New mineral policy was declared in 2011, which has 11 objectives.
Question 2.

- To maintain favourable environment to increase the value of minerals in the state.
- To increase the opportunities of employment.
- To develop new techniques for mineral mining and to put emphasis on mining of limestone, lignite etc.
- To encourage mechanized and scientific methods of mining, keeping in mind the government policies and conservation of minerals.
- To increase human resources for development of mining and mineral-based industries.
- To develop basic facilities in deserted areas.
- To develop basic facilities in mining areas.
- To encourage mining of noble base metals, industrial minerals and fertilizers.
- To encourage methane and lignite based industries and petroleum refineries.
- To simplify the rules and processes for removing the obstacles present in mining development.
