Summary
Protests against NHPC's proposed 11,200 MW Siang Upper Multipurpose Project turned violent in Pasighat on the night of 23-24 October 2026, after a 12-hour bandh. Arson reportedly hit an NHPC office and a police station, more than 40 police personnel were injured and the homes of local politicians were vandalised.
The district imposed Section 163 BNSS restrictions and the MHA sent about 250 CRPF Rapid Action Force personnel. The Indian Express revealed that NHPC had hired Concept Public Relations on a contract now worth about ₹10.91 crore to recast the dam as a development opportunity.
The government frames SUMP as a strategic buffer against China's upstream dam, while sections of the Adi community fear the loss of ancestral land and livelihoods.
WHY IT MATTERS FOR UPSC & STATE PCS
Violent protests broke out in Pasighat, East Siang, against the proposed Siang Upper Multipurpose Project on 23-24 October 2026. Two CRPF RAF companies were deployed and an Indian Express investigation exposed NHPC's ₹10.91 crore public-relations contract aimed at building local support.
Standard News
The Missing Link Was Consent, Not Communication
The commitment. The government's stated course for the Siang Upper Multipurpose Project is to complete a pre-feasibility report, explain the project's value and carry the affected Adi communities with it through dialogue.
On Sunday, Chief Minister Pema Khandu said misinformation was causing anxiety and called for facts, transparency and dialogue. The data. By October 2026, NHPC had spent about ₹10.91 crore on an outside PR agency. The Indian Express reports that the tender laid down monthly targets, including:
- 40 project staff - 10 local social-media influencers - four community events - two NGO tie-ups - 10 media-management engagements - two national-media engagements It also set out sentiment tracking and a database of opinion leaders. More than 30 executives were reportedly stationed in Itanagar. The result was a 12-hour bandh, tear gas at Geku and a night of arson in Pasighat that left more than 40 police personnel injured.
Where the
chain broke The usual weak links in environmental implementation are funding, monitoring and enforcement. None of those failed here. The link that broke came earlier: the sequence of consent. A pre-feasibility study is meant to establish whether a project is viable.
It is the stage at which a community's informed agreement should be sought and recorded, not manufactured. Instead, the approach unfolded in an order that inverted that logic:
- CSR money arrived first. In March 2024, the Siang Indigenous Farmers' Forum objected to allocations of ₹16.61 crore and ₹94.29 crore routed to district administrations.
- A persuasion machine followed. The PR tender itself acknowledged negative discourse over submergence, displacement and land loss and aimed to recast the dam as a development opportunity.
- Security came last. When the PR campaign failed to persuade, the State responded with Section 163 orders and an airlift of Rapid Action Force companies.
The strategic case is real None of this makes the strategic argument false.
China's roughly 60,000 MW Medog project upstream, under construction since July 2025, operates with no water-sharing treaty, only hydrological data arrangements. A 9.2 BCM reservoir could serve as a buffer against sudden flow changes.
Cabinet Minister Ojing Tasing claims 85% of residents accept the project. Siang Indigenous Farmers' Forum member Tajom Ejing says the affected villages reject it. That contradiction is precisely why measured, documented consent matters.
Neither claim can be tested by influencer metrics.
What is working: the project remains at the pre-feasibility stage, the Chief Minister is meeting community bodies such as the Arunachal Indigenous Tribes Forum and the State has publicly committed to dialogue. For the exam, the insight is that the Siang conflict is not a failure of communication.
It is a failure to treat informed consent as a precondition rather than a public-relations outcome and that failure is what turns a strategic asset into a security problem.
