1. Q1Multiple choice·1 mark
   Multi-purpose river projects, once hailed as the temples of modern India, have faced severe social criticism in recent decades primarily because:

   1. (a)They displace large numbers of local people and submerge their land and forests
   2. (b)They pushed farmers in the command areas from cash crops back to coarse food grains
   3. (c)They sent so much extra silt to downstream fields that the soil there lost fertility
   4. (d)They lowered the groundwater table in the command areas by drawing water from wells

4. Q4Short answer·2 marks
   Explain any two reasons why multi-purpose river projects have come under great opposition and scrutiny in recent years.
   Show answer and step marks

   1. First reason, any one of: large-scale displacement of local communities, who lose their land and livelihoods and get inadequate rehabilitation; submergence of large areas of land, forests and vegetation; regulating and damming rivers affects their natural flow, causing poor sediment flow and excessive sedimentation at the bottom of the reservoir; dams fragment rivers, making it difficult for aquatic fauna to migrate, especially for spawning; inter-state disputes over sharing the costs and benefits of the water; benefits go mostly to landowners and large farmers rather than the landless poor; irrigation changed cropping patterns to water-intensive crops, causing salinisation of soil; dams have triggered floods because of sedimentation, and have been linked to induced earthquakes and water-borne diseases; or any other valid reason.+1
   2. Second reason, a different one from the same list.+1

   Answer: Any two of: large-scale displacement of local people with inadequate rehabilitation; submergence of land and forests; altered river flow with excessive sedimentation; fragmented rivers blocking aquatic fauna migration; inter-state water disputes; benefits going mainly to landowners and large farmers; water-intensive cropping and soil salinisation; floods, induced earthquakes and water-borne diseases.
5. Q5Short answer·3 marks
   Explain any three objectives or advantages of multi-purpose river valley projects in India.
   Show answer and step marks

   1. First objective or advantage, any one of: irrigation for agriculture, especially in dry areas; generation of hydroelectric power; water supply for domestic and industrial use; flood control; inland navigation; fish breeding; recreation; integrating the development of agriculture and the village economy with rapid industrialisation; or any other valid advantage.+1
   2. Second objective or advantage, a different one from the same list.+1
   3. Third objective or advantage, a different one from the same list.+1

   Answer: Any three of: irrigation; hydroelectric power; water supply for homes and industries; flood control; inland navigation; fish breeding; recreation; linking agricultural and village development with industrialisation.
