What objections have been raised against multipurpose river valley projects? Explain any three.
Answers
1. Exaggerated Benefits on Irrigation:
It has been argued that irrigation benefits derived out of multi-purpose projects are exaggerated because the actual area irrigated by these projects is much less due to delay in the construction of field channels and water routes. Moreover delay in completion of these projects has resulted in high escalation of its cost.
2. Higher Cost of Hydropower:
Although hydro power is having the advantage of low operating cost, renewable source and eco-friendly but at the same time it is also subjected to long gestation period, delay in commissioning the project resulting escalation of project cost and higher initial cost. All these have resulted in a comparatively higher unit cost of generation in respect of hydro power.
3. Least Flood Control Benefit:
The multi-purpose projects have also failed to derive maximum benefit in respect of flood control as the embankments, drainage channels and flood protection schemes have failed miserably to achieve results.
Answer:
The multipurpose project are those that have been made by the government to accelerate the development of the nation economic system and also are a crucial factor for the irrigation and the agri-systems, there are some objections that are raised on these river valley projects such as:
Explanation:
1. Can lead to flooding: Due to the damaging of the river the water at the time of heavy rais can easily break this and cause a high wave on the country and even flooding on a large scale.
2. Adverse environmental impacts. : The environmental impacts that are associated with the floods and the earthquake that occurs due to the dam burst and the other impact by the water as it has the force and can destroy everything in its path.
3. It has a higher cost. : The use of dams is a heavy investment and has to be planned in advance hence it lads to costs.
4. Loss of habitat: The destruction of the primary habitats and evacuation of people living in the low lying areas thus leads to the habitations of flora and fauna and the man.
