Development projects in tribal areas must reconcile national interest with community consent. Discuss in the context of recent protests in Arunachal Pradesh.

The Siang Upper Multipurpose Project (SUMP) is an 11,000–11,200 MW dam that NHPC plans to build on the Siang, the name of the Brahmaputra in Arunachal Pradesh. It was declared a national project in 2008, and since October 2026 the Adi community has been protesting against it [1]. The dispute shows that national interest and consent go together, because a project imposed without consent rarely delivers.

National interest behind SUMP

• Strategic hedge: about 9.2 BCM of live storage could absorb sudden releases from China's upstream dam on the Yarlung Tsangpo [1].
• Flood moderation: regulating water flow would lower flood risk downstream in Assam [1].
• Energy and jobs: the dam would add large-scale clean power and promises jobs for local youth [1].

Why community consent is contested

• Displacement: the Adi say 40 villages would be affected and 27 submerged, taking ancestral land, farmland and homes [1].
• Consent seen as a PR problem: the Ministry of Power says it is handling villagers' concerns through "confidence building measures" and outreach [2]. That treats objection as misunderstanding.
• Trust deficit: activists have been arrested, and protesters rejected the State's offer of talks on 5 November 2026 [1].
• Design uncertainty: the project is still at the preliminary investigation stage [2]. Neither the submergence claims nor the flood-control claims can be checked yet.
• Cumulative ecology: the CWC counts 44 hydro projects proposed in the Siang basin, which has 114 fish species [3]. Assam downstream also has a stake.

Reconciling the two

• Gram sabha consent: follow the Forest Rights Act, 2006 [4], with no security pressure and no cash tied to agreeing.
• Disclose first: publish the reservoir level, the area to be flooded, and whether flood control or power comes first, before seeking consent [2].
• Basin-wide appraisal: expert appraisal committees should judge SUMP against the CWC's cumulative study [3]. An independent early review of earthquake design under the Dam Safety Act, 2021 is also needed.
• Alternatives and benefit-sharing: consider a smaller, flood-first reservoir and river-flow data-sharing with China. Pair them with fair resettlement and an equity stake for the community.

National interest and community consent can be reconciled through openness, rights-based consultation and basin-level planning. When villagers become stakeholders rather than obstacles, the project gains both legitimacy and speed. That consent-first model reflects constitutional protections for Scheduled Tribes and the inclusive decision-making of SDG 16, and makes Arunachal's rivers a shared national asset.
