Why in the news?
The Forest Advisory Committee (FAC) of the Union Environment Ministry has recommended in-principle forest clearance for the 1,000-MW Naying Hydroelectric Project on the Siyom River in Arunachal Pradesh, a tributary of the Siang. This comes amid protests against the larger 11,200-MW Siang Upper project, highlighting the tension between India's energy needs and ecological/security concerns in the ecologically sensitive Brahmaputra basin.
Summary
- The Forest Advisory Committee (FAC) has recommended in-principle forest clearance for the 1,000-MW Naying Hydroelectric Project on the Siyom River in Arunachal Pradesh, proposed by NEEPCO.
- The project will divert 470.8 hectares of forest land and affect an estimated 1,04,036 trees, with compensatory afforestation on 942 hectares mandated.
- The project is one of four planned in the Siang River Basin, while the larger 11,200-MW Upper Siang Multipurpose Project faces strong local opposition from the Adi community on cultural and livelihood grounds.
Highlights
Forest Clearance Recommended
The FAC has recommended in-principle forest clearance for the 1,000-MW Naying project, involving diversion of 470.8 hectares of forest land and affecting over 1 lakh trees.
Energy vs. Ecology Tension
The project is part of India's push for hydropower in the Siang basin, but faces scrutiny over ecological impact and is set against the backdrop of strong local protests against the larger Siang Upper project.
Strategic Dimension
The state government justifies the Siang Upper project as a national security imperative to counter China's proposed upstream dam on the Brahmaputra.
Background
The Naying Hydroelectric Project is one of several large hydropower projects planned in the Siang River Basin in Arunachal Pradesh, which is part of the larger Brahmaputra river system. The region is ecologically fragile and seismically active. The Forest Advisory Committee (FAC), a statutory body under the Ministry of Environment, Forest and Climate Change, evaluates proposals for diversion of forest land for non-forest purposes. Its in-principle clearance is a key step before final approval.
Key Analysis and Impact
The FAC's recommendation highlights the ongoing conflict between India's hydropower ambitions and environmental conservation. The project will divert 470.8 hectares of unclassed forest land in an area classified as 'high conservation value' and affect approximately 1,04,036 trees, with compensatory afforestation mandated on double the area. The cumulative impact assessment of the Siang basin has also recommended design changes, including lowering full reservoir level to maintain a minimum 1-km free-flowing river stretch between Tato-II and Naying. This comes amid heightened local opposition to the 11,200-MW Upper Siang project, with the Adi community citing cultural and livelihood threats.
Strategic and Security Angle
The state government has framed the larger Siang Upper project as a national security necessity to counter China's infrastructure development upstream on the Brahmaputra. This adds a geopolitical layer to the environmental debate, as India seeks to secure its energy needs and assert its water security in the face of Chinese dam construction in Tibet.
Way Forward
The in-principle clearance is not the final approval. The project proponent (NEEPCO) must now meet the conditions set by the FAC, including compensatory afforestation on contiguous land and potential design modifications. The final forest clearance will also require approval from the state government and further scrutiny. The broader debate on the Siang basin's hydropower potential versus its ecological and social costs will continue, especially given the strong local resistance.
Hydro Projects in Siang Basin
| Project | Capacity (MW) | River | Status |
|---|---|---|---|
| Upper Siang Multipurpose Project | 11,200 | Siang | Pre-feasibility; facing protests |
| Naying Hydroelectric Project | 1,000 | Siyom | In-principle forest clearance |
| Lower Siang | 2,700 | Siang | Planned |
| Tato-II | 700 | Siyom | Approved by CCEA (Aug 2025) |
Background GK
Textbook concepts you need to understand this news
- Forest Advisory Committee (FAC)
- A statutory committee under the Ministry of Environment, Forest and Climate Change that advises the government on matters related to the diversion of forest land for non-forest purposes, as per the Forest (Conservation) Act, 1980.
- In-Principle Forest Clearance
- A preliminary approval under the Forest (Conservation) Act, 1980, indicating that the government is agreeable to the diversion of forest land subject to certain conditions being met by the project proponent.
- Run-of-the-River Hydroelectric Project
- A type of hydroelectric project that does not require a large reservoir, using the natural flow of the river to generate electricity, with minimal water storage.
- Compensatory Afforestation
- The practice of planting trees on an alternative piece of land to compensate for the loss of forest cover due to a development project, often mandated under the Forest (Conservation) Act.

How exams will ask this
- Data: 1,000 MW capacity; ₹10,369 crore cost; 470.8 hectares forest land diverted; 1,04,036 trees affected.
- Nodal Body: Ministry of Environment, Forest and Climate Change (via the Forest Advisory Committee).
- Legal Point: Forest (Conservation) Act, 1980 (in-principle clearance under this Act).
Don't make this mistake!
Examiners may confuse the Naying project (1,000 MW) with the larger Upper Siang project (11,200 MW) or the Tato-II project (700 MW). Also, they might ask about the river: Siyom is a tributary of the Siang, which is the name of the Brahmaputra in Arunachal Pradesh. Do not confuse Siyom with Siang or the main Brahmaputra.

Stuck? Get it in one tap
The Forest Advisory Committee (FAC) has given a preliminary go-ahead for the 1,000-MW Naying hydroelectric project on the Siyom River in Arunachal Pradesh. This means the project can move forward, but it must meet conditions like planting trees on double the forest land it uses. The project is part of India's plan to build dams in the region, which some locals oppose due to cultural and environmental concerns.

Practice questions
Pick an answer, then read the explanation.
- Q1Easy
Which committee under the Ministry of Environment, Forest and Climate Change recommended in-principle forest clearance for the Naying Hydroelectric Project?
Explanation: The Forest Advisory Committee (FAC) is a statutory body under the Ministry of Environment, Forest and Climate Change that advises on the diversion of forest land for non-forest purposes under the Forest (Conservation) Act, 1980. The other bodies do not have this specific mandate.
- Q2Hard
Consider the following statements regarding the Naying Hydroelectric Project:
- 1.It is a 1,000-MW run-of-the-river project proposed on the Siyom River, a tributary of the Siang River in Arunachal Pradesh.
- 2.The project proponent is the National Hydroelectric Power Corporation (NHPC) and the estimated cost is ₹15,000 crore.
- 3.The Forest Advisory Committee has recommended that compensatory afforestation be done on double the area of forest land diverted.
Which of the statements given above is/are correct?
Explanation: Statement 1 is correct: the project is 1,000 MW, run-of-the-river, on the Siyom River. Statement 2 is incorrect: the project proponent is NEEPCO, not NHPC, and the cost is ₹10,369 crore, not ₹15,000 crore. Statement 3 is correct: the FAC mandated compensatory afforestation on 942 hectares, which is double the 470.8 hectares diverted. Hence option C is correct.
- Q3Medium
What is the estimated number of trees that will be affected by the Naying Hydroelectric Project?
Explanation: The FAC noted that the project will affect approximately 1,04,036 trees. 50,000 and 75,000 are lower estimates, while 1,50,000 is an overestimate. The correct figure from the news is around 1,04,000.
- Q4Medium
What is the primary reason cited by the Arunachal Pradesh government for pursuing the larger Siang Upper Multipurpose Project despite local opposition?
Explanation: The state government maintains that the SUMP is essential to counter China's proposed upstream dam and is a national security issue. Revenue generation, irrigation, and tourism are not the stated primary reasons for pursuing the project despite opposition.
