CBSE Geography Class 10 Resource and Development VBQ
Q.1. Discuss the problems which have been caused due to over-utilisation of resources. Suggest any two ways to save the resources.
“Indiscriminate use of resources has led to numerous problems”. Justify the statement in three points. [GBSE 2012, 14]
Ans. (I) Depletion of resources : Over-utilisation has led to the depletion of the resources for meeting the greed of a few individuals. For example, over-utilisation of petroleum products has led to a situation where most of the countries of the world are facing energy crisis.
(ii) Concentration of resources: This has divided the society into â€˜haves’ and â€˜have nots’ or the rich and the poor.
(iii) Global ecological crisis : Over utilisation of resources has led to the global ecological crisis such as global warming, depletion of ozone layer, pollution and land degradation.
(i) Minimising wastage.
(ii) Use of renewable resources.
Q.2. “The earth has enough resources to meet the need of all but not enough to satisfy the greed of even one person.”How is this statement relevant to the discussion of development ? Discuss. [CBSE 2013]
Ans. (i) Resources are vital for any developmental activity.
(ii) The irrational consumption and over utilization of resources may lead to socio economic and environmental problems.
(iii) Indiscriminate exploitation of resources led to global ecological crises such as global warming, environmental pollution, etc
(iv) The greedy and selfish individuals and exploitative nature of modem technology is the root cause for resource depletion at the global level.
(v) If the present trend of resource depletion by a few individuals and countries continues, the future of our planet is in danger.
(vi) There is need for sustainable development.
It means development should take place without damaging the environment and development in the present shout not compromise with the need of future generations’. .
Q.3. Why is there a need to conserve resources ? What was Gandhiji’s opinion regarding the conservation of resources ? [CBSE Sept. 2012]
Explain the importance of conservation of resources. [CBSE Sept. 2010, 2011,2014]
Why is it essential to have resource planning ? Give three reasons. [CBSE 2014]
Ans. (i) Limited supply : Most of the resources have limited supply as compared to their demand for example supply of fossil fuels is limited.
(ii) Pollution and global warming :
Overutilisation of natural resources may lead to environmental pollution for example over use of fossil fuel is a major factor responsible for global warming.
(iii) Socio economic problem : The destruction of forests and wildlife is not just
a biological issue. The biological loss is strongly correlated with the loss of cultural diversity. Such losses have increasingly marginalised and impoverished many indigenous and other forest-dependent communities, who directly depend on various components of the forest and wildlife for food, drink, medicine, culture, spirituality, etc. Within the poor, women are affected more than men. In many societies, women bear the major responsibility of collection of fuel, fodder, water and other basic subsistence needs. As these resources are depleted, the drudgery of women increases and sometimes they have to walk for more than 10 km to collect these resources. This causes serious health problems for women and negligence of home and children because of the increased hours of work, which often has serious social implications. Gandhiji was very apt in voicing his concern about resource conservation. He said, “There is enough for everybody’s need, and not for anybody’s greed. “According to him, they were the greedy and selfish individuals who were responsible for depletion of resources. He was in favour of producing for the masses than mass production.
Q.4. Why is there a need for resource planning ? What can happen if we don’t follow the principle of resource planning ?
Ans. (i) Most of the resources are limited in supply.
(ii) Most of the resources are unevenly distributed over the country.
(iii) Overutilisation of the resources may lead to pollution of the environment.
(iv) There is a need to plan the human resources because only then we would be able to develop our natural resources.
(i) Energy crisis
(ii) Global warming
Q. 5. Explain any four reasons responsible for land degradation in India.
Explain any four human activities which are mainly responsible for land degradation in India. Give any two suggestions to check land degradation. [CBSE 2014]
Ans. (i) Mining : Mining is one of the major factors responsible for land degradation. In states like Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha, deforestation due to mining have caused severe land degradation.
(ii) Overgrazing : During the long dry period, grass is grazed to the ground and torn out by the roots by animals. This leads to loosening of soil and it is easily washed away by rains. In states like Gujarat, Rajasthan, Madhya Pradesh, and Maharashtra overgrazing is one of the main reasons for land degradation.
(iii) Overirrigation : In the states of Punjab, Haryana, western Uttar Pradesh, overirrigation is responsible for land degradation due to waterlogging which leads to increase in salinity and alkalinity in the soil.
(iv) Processing of minerals : The mineral processing like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust in the atmosphere. It retards the process of infiltration of water into the soil after it settles down on the land. In recent years, industrial effluents as waste have become a major source of land and water pollution in many parts of the country.
(i) Plant more trees
(ii) We should not waste paper.
