The disadvantages of building large dams are:
- Damming of rivers and regulating their flow result in excessive sedimentation at the bottom of the reservoir. This may hamper aquatic life and their migration to other water bodies.
- Building of dams result in the submergence of land and vegetation. This results in the decomposition of vegetation.
- Construction of large dams results in the displacement of villagers and communities. The villagers have to give up their lands and their means of livelihood.
