Multi-purpose river projects
• Multi-purpose river projects large dams that serve several purposes in addition to impounding the water of a river and used later to irrigate agricultural fields. For example, the Sutluj-Beas river basin, the Bhakra–Nangal project etc.
(Objectives) Advantages of multi-purpose river projects are:
→ Electricity generation
→ Irrigation
→ Water supply for domestic and industrial uses
→ Flood control
→ Recreation
→ Inland navigation
→ Fish breeding
Disadvantages of Multi-purpose river projects are:
→ It affects the natural flow of river causing poor sediment flow and excessive sedimentation at the bottom of the reservoir.
→ It destroys the habitats for the rivers’ aquatic life.
→ It submerges the existing vegetation and soil if created on the floodplains.
→ It displaces the local people of the place where it is created.
→ These are unsuccessful in controlling floods at the time of excessive rainfall.
→ These projects induced earthquakes, caused water- borne diseases and pests and pollution resulting from excessive use of water.
Movements against Mult-purpose river projects
• These projects cause of many new social movements like the ‘Narmada Bachao Andolan’ and the ‘Tehri Dam Andolan’ etc.
→ This is due to the large-scale displacement of local communities.
• Inter-state water disputes are also becoming common with regard to sharing the costs and benefits of the multi-purpose project.
