The Etalin hydropower project in Arunachal Pradesh was recently abandoned in its current configuration.
The design included two run-of-the-river projects with limited storage that required concrete gravity dams on the Tangon and Dri rivers.
Since its commencement in 2008, it has been embroiled in various disputes, including environmental harm, forest invasion, and tribe displacement.
What is the Importance of the Dir and Tangon River?
The Dir and Tangon rivers in Arunachal Pradesh, India, are tributaries of the Dibang River (a tributary of the Brahmaputra).
Hydrological: By providing water for cultivation and hydropower generation, both rivers contribute to the overall hydrology of the region.
Ecological: The Dir and Tangon rivers are home to a wide variety of plant and animal life, including uncommon and endangered species.
Attractions for Tourists: The beautiful grandeur of the Dir and Tangon rivers, as well as the Dibang, is a popular tourist attraction.
What are the Main Concerns About the Etalin Hydel Project?
Effects on the environment -
The proposal will entail building a massive dam on the Dibang River, submerging a significant amount of forest and wildlife habitat.
This might result in the relocation of residents and have a substantial impact on the biodiversity of the region.
Local Community Displacement -
Due to the project, thousands of people will be displaced from their homes and livelihoods. Many of them are indigenous groups who rely on the Dibang River for a living.
The following are the effects on the river ecosystem -
The project would alter the river's natural flow, affecting fish migration and spawning.
This would be detrimental to local communities that rely on fishing for a living.
Geological and seismic hazards:
When the project underwent environmental clearance (EC), the South Asia Network on Dams, Rivers, and People (SANDRP) highlighted the geological and seismic dangers and threats to biodiversity.
Recent Issue Developments:
The Forest Advisory Committee (FAC) has requested that the Arunachal Pradesh government return to the drawing board and resubmit the project proposal.
The Future Perspectives -
Community-led Approach: The region's local populace should be contacted and involved in decision-making to ensure that the final choice reflects their concerns.
Ecologically Sensitive Areas: To guarantee that areas in danger of biodiversity loss remain undisturbed, they should be correctly designated.
Environment Influence Assessment (EIA): A thorough examination of the project's impact on the local environment should be conducted.
