Describe the factors that are responsible for the various objections against the multi-purpose projects.

The factors that are responsible for the various objections against the various multipurpose projects are as given below:
(l) Failure of the projects to achieve their objectives.
(ll) Some dams that were constructed to control floods were responsible for the floods due to sedimentation in the reservoir.
(iii) Generally, big dams are not successful in controlling flood at the time of heavy and excessive rainfall. Such floods have occurred in Maharashtra and Gujarat in 2006.
(iv) Sedimentation deprived flood plains of silt, a natural fertiliser and was responsible for land degradation.
(v) Multipurpose projects induced earthquakes, caused water-borne diseases and pests and pollution resulting from excessive use of water.
