(b) Region having high annual rainfall and large population: Not suffering from water scarcity
(c) Region having high annual rainfall but water is highly polluted: Suffering from water scarcity
(d) Region having low rainfall and low population: Suffering from water scarcity
(ii) Which one of the following statements is not an argument in favour of multipurpose river projects?
(a) Multi-purpose projects bring water to those areas which suffer from water scarcity.
(b) Multi-purpose projects by regulating water flow helps to control floods.
(c) Multi-purpose projects lead to large scale displacements and loss of livelihood.
(d) Multi-purpose projects generate electricity for our industries and our homes.
Answer:
(c) Multi-purpose projects lead to large scale displacements and loss of livelihood.
(iii) Here are some false statements. Identify the mistakes and rewrite them correctly.
(a) Multiplying urban centres with large and dense populations and urban lifestyles have helped in proper utilisation of water resources.
(b) Regulating and damming of rivers does not affect the river’s natural flow and its sediment flow.
(c) In Gujarat, the Sabarmati basin farmers were not agitated when higher priority was given to water supply in urban areas, particularly during droughts.
(d) Today in Rajasthan, the practice of rooftop rainwater water harvesting has gained popularity despite high water availability due to the Indira Gandhi Canal.
Answer:
(a) Multiplying urban centres with large and dense populations and urban lifestyles have led to the overexploitation of water resources.
(b) Regulating and damming of rivers significantly alter the river’s natural flow and its sediment flow.
(c) In Gujarat, the Sabarmati basin farmers were agitated when higher priority was given to water supply in urban areas, particularly during droughts.
(d) Today in Rajasthan, the practice of rooftop rainwater harvesting has gained popularity despite low water availability in many areas due to the Indira Gandhi Canal.
2 . Answer the following questions in about 30 words.
(i) Explain how water becomes a renewable resource.
(ii) What is water scarcity and what are its main causes?
(iii) Compare the advantages and disadvantages of multi-purpose river projects.
Answer:
(i) Water becomes a renewable resource through the process of the hydrological cycle, where water evaporates from oceans and land surfaces, forms clouds, and falls back to Earth as precipitation, continually replenishing water sources.
(ii) Water scarcity refers to the situation where the demand for water exceeds the available water resources. Its main causes include overpopulation, pollution, climate change, inefficient water management, and over-extraction of groundwater.
(iii) Multi-purpose river projects bring benefits like irrigation, flood control, and hydroelectric power generation. However, they also lead to environmental degradation, displacement of people, and loss of biodiversity, causing social and ecological impacts.
3 . Answer the following questions in about 120 words.
(i) Discuss how rainwater harvesting in semi-arid regions of Rajasthan is carried out.
(ii) Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.
Answer:
(i) In semi-arid regions of Rajasthan, rainwater harvesting is crucial due to scarce water resources. Traditional methods like ‘khadins’ and ‘tankas’ are used. ‘Khadins’ are embankments constructed across slopes to capture rainwater, which is then stored in ‘tankas’, underground tanks lined with lime. ‘Nadis’ are small earthen dams built across streams to collect rainwater. Modern techniques involve rooftop rainwater harvesting, where rainwater is collected from rooftops and stored in underground tanks. These methods have helped communities to cope with water scarcity by ensuring a steady supply of water for domestic use and agriculture, contributing to sustainable water management in the region.
(ii) Modern adaptations of traditional rainwater harvesting methods involve incorporating technology to enhance efficiency and scalability. In semi-arid regions like Rajasthan, rooftop rainwater harvesting systems are installed in buildings. These systems include gutters and pipes to collect rainwater from rooftops, which is then filtered and stored in underground tanks or reservoirs. Additionally, check dams and percolation tanks are constructed to recharge groundwater. In urban areas, permeable pavements and green roofs are used to allow rainwater infiltration.
These adaptations aim to maximize rainwater capture and minimize runoff, thereby replenishing groundwater and mitigating water scarcity. By blending traditional wisdom with modern technology, these methods offer sustainable solutions for water conservation and management in diverse settings.
Chapter 3 Water Resources Summary
In Chapter 3 of NCERT Geography Class 10, Water resources refer to the freshwater available on Earth, including rivers, lakes, groundwater, and glaciers. They are important for various human activities like agriculture, industry, and domestic use. However, water scarcity is a pressing issue due to factors like overexploitation, pollution, and uneven distribution. Multipurpose river projects aim to harness water for irrigation, hydroelectricity, and flood control. Rainwater harvesting techniques, such as rooftop harvesting and check dams, are employed to augment water availability, especially in arid regions. Sustainable water management practices are essential to ensure equitable access to clean water and mitigate water-related challenges.
