Answer: Big dam projects cause large scale displacement of people. The displaced people have to give up their homes and their lands. The displaced people do not get the compensation they are promised by the government and are put to a lot of hardship.
Massive dams are much more than simply machines to generate electricity and store water. Physical impact up stream includes loss of land, stagnant water table, habitat destruction, and change in water characteristics dust, air and water pollution.
How do dams negatively affect the economy?
Large dams have long been promoted as providing “cheap” hydropower and water supply. The average cost overrun of dams is 56\%. This means that when a dam is predicted to cost $1 billion, it ends up costing $1.56 billion.
What are the effects of check dams?
Reduce velocity and may provide aeration of the water. Check dams prevent gully erosion from occurring before vegetation is established, and also cause a high proportion of the sediment load in runoff to settle out.
What are the disadvantages of big dams?
The building of large dams can cause serious changes to the earth’s surface and lead to geological damage….Disadvantages of Building a Dam.

The results of our social literature review discuss the major positive and negative social impacts of hydroelectric development. Social benefits are primarily economic growth and improved flood control, while negative social impacts are displacement, adverse effects to human health, and livelihood changes.
What are the social and environmental impacts of large dams?
Subject area: Summary. Large dams are often criticized because of their negative environmental and social impacts: changes in water and food security, increases in communicable diseases, and the social disruption caused by construction and involuntary resettlement.
What are the flaws of dams?
Flaws include both the shortcomings of the dam itself as well as ecological and social impacts. In terms of the former, Scudder says that dams, on the average, can be expected to get clogged with sediment at a rate of about 0.5 to 1 percent per year.
Is building a dam an ethical or an ecological concern?
This happens to be an ethical concern. The building of large dams can result in serious ecological damage. For example, the building of the Hoover Dam in the USA prompted a number of earthquakes and has depressed the earth’s surface at its location. This is an alarming matter as it may lead to devastation.
How can we make dams work for humans everywhere?
In general, the way to make dams work for humans everywhere, Scudder suggests, is to address the social and environmental impacts both downstream and upstream of any dam project before the structure is even built, and to evaluate the situations in river basins where dams have already been constructed.
