Environmental impacts
Displacement of communities
High costs
All of the above

The correct answer is: All of the above.

Hydropower projects in Arunachal Pradesh have been associated with a number of major concerns, including environmental impacts, displacement of communities, and high costs.

  • Environmental impacts: Hydropower projects can have a significant impact on the environment, including the loss of forests, wetlands, and other habitats. They can also disrupt the flow of rivers, which can impact fish populations and other aquatic life.
  • Displacement of communities: The construction of hydropower projects often requires the displacement of communities, who may be forced to leave their homes and land. This can have a devastating impact on the lives of these communities, who may lose their livelihoods and their connection to their traditional way of life.
  • High costs: Hydropower projects are often very expensive to build and operate. This can make them a burden on the local economy, and can also make it difficult for these projects to compete with other forms of energy generation.

In addition to these concerns, there are also concerns about the social and political impacts of hydropower projects in Arunachal Pradesh. These projects have been linked to human rights abuses, corruption, and conflict.

Overall, hydropower projects in Arunachal Pradesh have a number of major concerns associated with them. These concerns need to be carefully considered before any new projects are approved.
