Important Questions NCERT Class 10 Social Science Chapter 3 Water Resources
Question. “Water scarcity may be an outcome of large and growing population in India.” Analyse the statement.
Ans. A large population leads to greater demand for water.
(i) A large population means more water not only for domestic use but also to produce more food in various agricultural practices.
(ii) Most of the Indian cities are facing the problem of water due to growing population. This happens because large amount of ground water is pumped out in densely populated colonies. This has drastically lowered the water table.
(iii) Large industries also makes huge demand on water. Further industrial pollution often pollutes the water bodies which further aggravates the situation.
Question. How has ever increasing number of industries in India made worse position by exerting pressure on existing fresh water resources? Explain.
Ans. After independence, industries are increasing at a rapid pace and have put pressure on existing fresh water resources, fresh water is limited, though renewable. In India, over-exploitation and mismanagement of this resource by industries is aggravating the water stress day-by-day.
(i) Industries especially heavy industries use huge amount of fresh water, they also pollute and waste a large amount of water.
(ii) These industries often depend on hydroelectric projects and this electricity is generated through damming the rivers upstream. So, the river almost dries in the lower stream areas.
(iii) Industries dump the chemical waste in the river, lake, etc. which then consequently pollute the water dangerously. These also contaminate the groundwater through seepage of industrial wastes. So, the increasing number of industries exert pressure on existing fresh water resources.
Question. Mention any four main objectives of multipurpose river valley projects. Name any two Multipurpose Project of India.
Ans. A project where many uses of the impounded water are integrated with one another is known as multipurpose project. It is built for irrigation, power generation, water supply, flood control, recreation, etc.
(a) Bhakra Nangal project
(b) Sardar Sarovar project
Question. List any three advantages and three disadvantages of multipurpose river project.
Ans. (i) These are an important source of power generation.
(ii) They provide us pollution free and economical energy which is the backbone of industry and agriculture.
(iii) These projects control the floods because water can be stored in them. These projects have converted many, rivers of sorrows into rivers of boon.
(iv) These projects are the main source of irrigation and also help in conserving soil.
(i) Due to the construction of dams there are no adequate floods in the river. Because of this, the soil of the downstream regions do not get nutrient rich silt.
(ii) Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning.
(iii) It result in displacement of local communities. The Local people often have to given up their land and livelihood and their meagre access and control over resources.
Question. 'An area or region may have ample water resources but is still facing water scarcity'. Give any three arguments to support the statement.
Ans. Many of our cities face this problem; they have adequate supply of water but much of it is unfit for consumption. Many of our cities are on rive banks, but the river water is no longer suitable for consumption because of the toxic wastes it receives.
This is also seen in many hilly areas where rain water is not adequately conserved.
Question. Why is roof top water harvesting important in Rajasthan? Explain.
Ans. Roof top water harvesting is important in Rajasthan because :
(i) It provides a good source of drinking water.
(ii) The rainwater can be stored in the tanks till the next rainfall, making it an extremely reliable source of drinking water when all other sources are dried up, particularly in the summers.
(iii) Rainwater, or palar pani, as commonly referred to in these parts, is considered the purest form of natural water.
(iv) Many houses construct underground rooms adjoining the tanks' to beat the summer heat as it keeps the room cool.
(v) Some houses still maintain the tanks since they do not like the taste of tap water.
Question. "In recent years multipurpose projects and large dams have come under scrutiny and opposition". Explain why?
Ans. The various reasons why multipurpose projects and large dams have come under scrutiny and opposition is because of the following reasons.
They affect natural flow of running water:
(i) Hence, it causes excessive sedimentation at the bottom of the reservoir.
(ii) It results in rockier stream beds.
(iii) They also fragment rivers making it difficult for aquatic fauna to migrate, especially for breeding.
Affect natural vegetation and soil :
(i) The reservoirs that are created on the floodplains also submerge the existing vegetation and soil leading to its decomposition over a period of time.
(ii) The flood plains are deprived of silt, a natural fertiliser, further adding on to the problem of land degradation.
(i) The dams create conflicts between people wanting different uses and benefits from the same water resources.
(ii) Inter-state water disputes are also becoming common with regard to sharing the costs and benefits of the multi-purpose project.
Cause of many social movements:
(i) They have been a cause of many new social movements like the ‘Narmada Bachao Andolan’ and the ‘Tehri Dam Andolan’ etc.
Displacement of people :
(i) They results in the large-scale displacement of local communities.
(ii) Local people often had to give up their land, livelihood for the project.
(iii) This leads to widening of the social gap
(iv) The local people are not benefiting from such projects.
Failure to control flood :
(i) The dams that were constructed to control floods have often triggered floods due to sedimentation in the reservoir and at the time of excessive rainfall.
(ii) It was also observed that the multi-purpose projects induced earthquakes, caused waterborne diseases.
Change in cropping pattern:
(i) Availability of irrigation has also changed the cropping pattern.
(ii) Farmers have shifted to water intensive and commercial crops.
(iii) This has great ecological consequences like salinisation of the soil.
(iv) It has increased the social gap between the richer landowners and the landless poor.
