\nAns.<\/strong> (i) The ever-increasing number of industries has made matter worse by exerting pressure on the existing freshwater resources.
\n(ii) Industries need power which is produced from water. Multipurpose projects produce the power.

Q.4. \u201cOverpopulation or large and growing population can lead to water scarcity.\u201d Explain. Mention any two lessons which you have learned from this.<\/strong>
\nAns.<\/strong> Overpopulation or large and growing population can lead to water scarcity as :
\n(i) More population means more demand for water.
\n(ii) A large population means more water not only for domestic use but also to produce more food.
\n(iii) To facilitate higher foodgrain production, water resources are being over-exploited to expand the irrigated areas and the dry season agriculture.
\n(iv) Overutilisation of water results in lowering of the groundwater levels.
\nLessons :
\n(i) There is need to check the growth of the population.
\n(ii) Human beings need to care for nature.<\/p>\nQ.5. \u2018Large multipurpose projects also lead to land degradation.\u2019 Explain.<\/strong>
\nAns.<\/strong> Multipurpose projects lead to land degradation because :
\n(i) Irrigation has changed the cropping pattern of many regions with farmers shifting to water-intensive crops. This has led to the salinization of the soil.
\n(ii) Regulating and damming rivers affect rivers’ natural flow, causing poor sediment flow.
\n(iii) The flood plains are deprived of silt.
\n(iv) Multipurpose projects induce pollution which leads to land degradation.<\/p>\nQ.6. Explain various problems associated with poor people due to the construction of large dams. [CBSE 2013]<\/span><\/strong>

\n(i) Narmada Bachao Andolan was started against the Sardar Sarovar Dam being
\nbuilt across the Narmada river in Gujarat.
\n(ii) Tehri Dam Andolan \u2013 Resistance to these projects has primarily been due to the large-scale displacement of local communities.
