Answer 2

Answer:

Multipurpose projects and large dams have come under scrutiny and opposition because of the following reasons: Large dams affect the natural flow of rivers. This results in hampering the flow of sediments. Excessive accumulation of sediments in the reservoirs causes damage to the marine life.

In recent years, multipurpose projects and large dams have come under great scrutiny and opposition for a variety of reasons.

(i) Regulating and damming of rivers affect their natural flow.

(ii) River's diversion and barricading due to building of dams affect migration and spawning of aquatic life.

(iii) The reservoirs lead to decomposition of soil and land degradation.

(iv) The dams have triggered floods due to sedimentation in the reservoir and release of excess water during heavy rains.

(v) Large scale displacement of local communities, local people who give up their land for the projects hardly receive any benefit.

(vi) Interstate water disputes with regard to sharing the costs and benefits of multi-purpose projects are leading to tension between states, e.g., KaveriGodavari dispute, Sabarmati water dispute.

(vii) Sometime multipurpose projects induced earthquakes, caused water borne-diseases and pests, and led to pollution resulting from excessive use of water.
