Question
Mention the reaons for objections to big dams.
Solution
The reasons for objections:
(i)The dams that were constructed to control floods have triggered floods due to sedimentation in the reservoir.
(i)The big dams have mostly been unsuccessful in controlling floods at the time of excessive rainfall.
(ii) The floods have not only devastated life and property but have also caused extremely soil erosion.
(iii) Sedimentation also meant that the flood plains were deprived of silt, a natural fertiliser, further adding on to the problem of land degradation.
(iv) It was also observed that the multipurpose projects or big dams induced earthquakes, caused water borne diseases and pests and pollution resulting from excessive use of water.
