Advantage of dam✡

1. Dams provide us with a source of clean energy.

2. Dams help us to retain our water supply.

3. This technology provides us with critical recreational opportunities.

4. A well-constructed dam provides several flood-control benefits.

5. Dams give us a way to irrigate croplands that may not receive enough moisture.

6. A dam can provide a stable system of navigation.

7. Reservoirs can serve as a source of drinking water.

-----------------------------------------------------------

Disadvantage ✡

1.Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning, i.e , to produce eggs.

2.It resulted in displacement of local communities.

3.The multipurpose projects induced earthquake, caused waterborne diseases......

4.Relocation is another big concern. People living in villages and towns that are in the valley that could be flooded, must move out. Hence, they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power plant constructions can go ahead. This happens to be an ethical concern.

5.The building of large dams can cause serious geological damage, for instance, the building of the Hoover Dam in the USA triggered a number of earth quakes and has depressed the earth’s surface at its location. This is an alarming matter.

6.However, modern planning and design of dams have also reduced the possibility of certain disasters occurring.
