What are the disadvantages of multi purpose project?

Question

Answer

The disadvantages of multi-purpose projects are as follows :-
1) They causes large-scale displacement of local communities and submergence of trees and vegetation .

2) Big dams have been unsuccessful in controlling floods at the time of excessive rainfall .

3) Regulating and damming of rivers affect their natural flow , causing excessive sedimentation at the bottom of the reservoirs , adding to the problem of land degradation .

4) Dams fragment rivers , making if difficult for aquatic fauna to migrate .

5) Dams were constructed to control floods but they have triggered floods , devastating life and property and causing soil erosion .

Answer

Following are the disadvantages of multipurpose project->
¹. multipurpose project success Dam lead to large displacement of people.
2. damage to aquatic life.
3. poor sedimentation at the bottom of the Dam.
4. the natural flow of river is changed.

Answer

Disadvantages of Multi-Purpose Projects

There are several disadvantages of multi-purpose projects that should be taken into consideration before embarking on such a project.

1. Complexity and Cost

Multi-purpose projects tend to be very complex and expensive due to the number of different purposes they serve. This can make them difficult to plan, design, and construct, and can also increase the risk of delays and cost overruns.

2. Conflicting Objectives

One of the biggest challenges of multi-purpose projects is balancing the different objectives of each purpose. For example, a dam built for irrigation purposes may conflict with the needs of downstream ecosystems, or a hydroelectric plant may harm fish populations.

3. Environmental Impact

Multi-purpose projects can have significant environmental impacts, particularly if they involve dams or other large-scale infrastructure. These impacts can include loss of habitat, disruption of natural water flows, and changes to water quality.

4. Social and Cultural Impacts

Multi-purpose projects can also have social and cultural impacts, particularly if they involve the displacement of communities or the destruction of cultural sites. These impacts can be difficult to mitigate and can lead to social unrest and conflict.

5. Maintenance and Longevity

Multi-purpose projects require ongoing maintenance and upkeep, which can be costly and time-consuming. Additionally, these projects may have a limited lifespan and may need to be decommissioned or replaced after a certain period of time.

Overall, while multi-purpose projects can offer significant benefits, they also come with a range of challenges and drawbacks that should be carefully considered before proceeding with such a project.

Answer

It has a lot of Disadvantages i.e. 1 It lead  to displacement of many people living near  the area where  dam has to be built.2 It causes  a lot of salination. 3 Sometimes in the case of high rainfall  dams are the main reason for flood while they are constructed for flood control

Answer

Often doesnt fulfil purposes for which it was builtdisplaces large no.  of pplcauses water environment disturbance... etc...

Answer

1. Multipurpose project affects the natural flow of water.
2. Causes the exercises sediments at the bottom of the river which makes stream bed rockier.
3. It causes the poor habitat of aquatic life.
4. It also causes no migration of aquatic fauna.
5. It also causes new social movement like 'Narmada bachao movement'and 'Tehri dam andolan'
