Chenab Q.9 In which region, people built 'Guls' and 'Kuls' for irrigation? Ans. Western Himalayas Q.10 Which state has made rooftop rainwater harvesting structure compulsory to all the houses across the state? Ans. Tamil Nadu PAGE# 1 SHORT ANSWER TYPE QUESTIONS Q.11 How have industrialisation and urbanisation aggravated water scarcity in India? Ans. (1) Industrialisation: Industries are heavy users of water. They also require energy to run machines. Much of this energy comes from hydroelectric power. (2) Urbanisation: (i) Multiplying urban centres with large and dense populations and urban lifestyles have not only added to water and energy requirements but have 2 further aggravated the problem. (ii) Most housing societies have their own groundwater pumping devices to meet their water needs. This leads to depletion of underground water. Q.12 Explain three ways in which irrigation schemes have changed the social landscape of the region. Ans. (1) It has increased the social gap between the rich landowners and the landless poor. (2) Dams have created conflicts between people who have different opinion on the use of water. (3) Dams have created inter-state water disputes. For example, Krishna-Godavari water dispute. Q.13 How were the underground tankas beneficial to the people of Rajasthan? Explain. Ans. (1) They are extremely reliable source of drinking water when other sources are dried up. (2) This is considered purest form of natural water. (3) Many houses constructed rooms adjoining the tankas to beat the summer heat as it would keep the room cool.

Punjab Q.9 Name the largest artificial lake built in 11th century? Ans. Bhopal lake SHORT ANSWER TYPE QUESTIONS Q.10 Why we should conserve our water resources ? Explain any three reasons. Ans. Following are the reasons that we need to conserve and manage our water resources: (1) Large growing population: This causes greater demand of water and unequal access of people to water resources. Greater demand means demand for food and rise in foodgrain production which needs more water. (2) Over-exploitation of water resources: To expand irrigated areas and dry season, farmers have their own wells and tubewells which may lead to falling groundwater levels. (3) Intensive industrialisation: In industry for various purposes, water is heavily used. To run industries power is required and 22% of it comes from hydroelectricity. (4) Urbanisation: Large and dense population add to water demand and scarcity. Most pump groundwater to meet their needs and water tables are falling consistently. (5) Lack of rainwater harvesting : It is not mandatory except in Tamil Nadu. PAGE# 3 Q.11 What objections have been raised against multi-purpose river valley projects? Explain any three. Ans. (1) Multi-purpose river valley projects have triggered floods due to sedimentation in the reservoir. Moreover, the big dams have mostly been unsuccessful in controlling floods at the time of excessive rainfall. (2) Due to sedimentation, the flood plains remain deprived of silt, a natural fertilizer, further adding to the problem of land degradation. (3) They often induce earthquake. (4) They cause water borne diseases and pests and pollution resulting from excessive use of water. Q.12 What is rainwater harvesting? Explain any two different methods of rainwater harvesting in different regions of India. Ans. (1) Rainwater harvesting is a technique by which recharge of water can be increased. It is done by artificial recharging of abandoned wells. (2) Different methods of rainwater harvesting are as follows: (i) In hill and mountainous regions, people built diversion channels like the 'guls' or 'kuls' in the Western Himalayas for agriculture. (ii) Rooftop rainwater harvesting is commonly practised to store drinking water in Rajasthan. (iii) In the flood plains of Bengal, people develop inundation channels to irrigate their fields. (iv) In arid and semi-arid regions, agricultural fields were converted into rainfed storage structures that allow the water to stand and moisten the soil like the 'Khadins' in Jaisalmer and 'Johads' in other parts of Rajasthan.
