The construction of large dams leads to

(i) social, and

(ii) environmental problems. List two problems in each case.

i. Social problems – Vast area of land get submerged under water so many people become homeless. It also leads to unequal distribution of water. People close to the source will get enough water for agriculture whereas those far from the source cannot get sufficient water.

ii. Environmental problems – Large-scale deforestation, loss of flora and fauna of that particular area, displacement of large number of people living in that area etc.
