Save Silent Valley Movement

The Silent Valley is well-known for its rare animal and bird species. Because this forest is lushly forested and has a huge area under vegetation, there is no loud sound in the forest apart from that of some birds and insects, which is why this valley is identified as Silent Valley. This Valley covers a surface area of 90 square kilometers. The Kunthipura river passes through the Silent Valley. This runs for about 15 kilometers and falls from an altitude of 2400 meters. According to mythology, the Pandavas are said to have chosen to settle in the silent valley after losing their empire and land.

  • The silent valley movement arose in response to the official statement of the construction of a dam on Kunthipura's upper stream, also called the silent valley project.
  • The first survey was conducted by the state government in 1958.
  • The dam over the top stream, according to British technicians, can help generate hydroelectricity.
  • The planning commission gave its approval in 1973. The project's main goal was to produce 120 megawatts of electrical power and water to yield 240 megawatts of electric power.
  • In 1976, a bunch of environmentalists began to oppose the silent valley project.
  • A task force was set up under the presidency of the then Vice-President of the World Wildlife Fund India.
  • The task force continued to work for over a year and conducted several surveys that recommended that the project be halted.
  • The task force's report stated that the project's construction will lead to significant harm to the green cover. It will eventually harm flora and fauna, as well as the water. This will result in high-scale forest disasters.
  • This report also advised that in case the government is compelled to construct the dam, then they must also adhere to the 17 recommendations outlined in the given report.
  • In 1979, the task force's leader admitted that the initial report was a blunder and made a plea to the government to cease the project entirely.
