Summary
The All Adi Youth Association has demanded that the Central Armed Police Forces and State Police be withdrawn from the Siang river belt in Arunachal Pradesh. The forces were deployed amid protests against the pre-feasibility report and related surveys for the Siang Upper Multipurpose Project.
NHPC Limited is pursuing the project, which is estimated to generate 11,000 MW. The Centre and the State present it as a strategic counter to China's planned 60,000 MW Medog hydropower station on the Yarlung Tsangpo, which flows into India as the Siang.
The association condemned recent clashes between protesters and security personnel in Siang and Upper Siang districts. It argued that the Adi community traditionally settles disputes through its customary council, the Kebang and rejected the government's claim that most affected families support the pre-feasibility report.
It also said that memoranda signed with some villagers do not reflect the views of all 27 villages the project would affect.
WHY IN NEWS FOR UPSC & STATE PCS
On October 6, 2026, All Adi Youth Association secretary Okut Taki told journalists in Itanagar that the militarisation of the Siang belt has created law-and-order concerns. He demanded that security forces be withdrawn after clashes between protesters and security personnel at several places in Siang and Upper Siang districts over surveys for the proposed 11,000 MW Siang Upper Multipurpose Project.

Two Maps of One River: Why Consent Is Part of Border Security In the
late 1950s, when this stretch of the Himalaya was still administered as the North East Frontier Agency, Jawaharlal Nehru set out a doctrine for governing it. Known as the Tribal Panchsheel, it held that tribal communities should develop along their own genius, that their rights in land and forest should be respected and that the state should work through their own social and cultural institutions, not in rivalry to them.
Few regions had a more developed institution to work through than the Adi villages of the Siang valley, which settled disputes through the Kebang, a village council older than the Indian state. Nearly seven decades later, that doctrine is being tested on the same river.
The strategic map From Delhi, the Siang is a line on a map of hydro-rivalry.
It begins in Tibet as the Yarlung Tsangpo, where China is building the 60,000 MW Medog hydropower station. It crosses into Arunachal Pradesh as the Siang, then joins the Dibang and the Lohit in Assam to become the Brahmaputra.
The government's case for the 11,000 MW Siang Upper Multipurpose Project, being pursued by NHPC Limited, rests on this geography. A large Indian storage dam downstream of Medog is meant to establish India's own use of the water and buffer Assam against sudden releases from upstream.
That case is not frivolous. A river shared with a far more powerful upstream neighbour is a genuine vulnerability.
The lived map From the Siang valley, the same river looks different.
The All Adi Youth Association says 27 villages would be affected. The government points to memoranda of understanding signed with villagers "in favour" of the pre-feasibility report. The association says those memoranda do not speak for all the affected villages.
Where there should be a conversation, there are Central Armed Police Forces, State Police and clashes in Siang and Upper Siang districts. The association's demand is pointed. The Adi have always resolved disagreements through the Kebang, so security forces are the wrong instrument for resolving a disagreement about a dam.
Where the
parallel breaks The Tribal Panchsheel was written for a frontier without an upstream mega-dam. Nehru's era did not face a neighbour engineering the river at its source and today's strategic pressure is real in a way his was not.
To pretend the old doctrine settles the question would be naive. But the same frontier also teaches the other half of the lesson. In 1962, NEFA was where India learned that a border is held not only by troops and infrastructure but by the loyalty of the people who live on it.
A dam surveyed under armed guard may yield a pre-feasibility report. It will not yield the trust a border society needs.
