What is a dam? Why do we seek to build large dams? While building large dams, which three main problems should particularly be addressed to maintain peace among local people? Mention them.

1. What is a dam?

A dam is a barrier built across a river or stream to obstruct, restrict, or retain the flow of water, creating a large reservoir or lake behind it.

2. Why do we seek to build large dams?

We build large dams to achieve several key developmental goals:

• Hydroelectric Power Generation: To harness the kinetic energy of falling water to rotate turbines and generate clean electricity.
• Irrigation: To store water and distribute it through canal networks to agricultural fields, ensuring crop survival during dry seasons.
• Water Supply and Flood Control: To provide a reliable source of drinking and industrial water, and to regulate river flow to prevent downstream flooding.

3. Three main problems to be addressed to maintain peace among local people:

• Social Problems: Large dams displace vast numbers of local peasants and tribal communities without adequate compensation or proper rehabilitation, stripping them of their homes and livelihoods.
• Economic Problems: They consume enormous amounts of public funds without delivering proportionate benefits to the local population, often benefiting only a select group of wealthy farmers and industrialists.
• Environmental Problems: They lead to massive deforestation, loss of biodiversity, and ecological imbalance as vast tracts of forest and fertile agricultural land are permanently submerged under the reservoir water.
