Siang Dam: Development, Security & Indigenous Rights

SIANG DAM: DEVELOPMENT, SECURITY AND INDIGENOUS RIGHTS

WHY IN THE NEWS ?

• Rising Opposition: The proposed 11,200-MW Siang Upper Multipurpose Project (SUMP) in Arunachal Pradesh is facing protests from indigenous Adi communities concerned about displacement, livelihood losses and cultural heritage.
• Strategic Context: The Centre considers the project important to counter China’s proposed 60,000-MW hydropower project on the Yarlung Tsangpo River in Tibet.

SIANG UPPER MULTIPURPOSE PROJECT: FEATURES AND SIGNIFICANCE:

• Project Overview: The SUMP is a proposed 11,200-MW hydropower project on the Siang River in Arunachal Pradesh and is expected to become India’s largest hydropower project.
• Historical Background: The proposal dates back to 1982, when the Brahmaputra Board explored hydropower development on the Siang and Subansiri rivers.
• Strategic Importance: India’s interest increased after China began advancing its upstream hydropower plans on the Yarlung Tsangpo, which flows into India as the Siang.
• Water Security: The project is considered important for monitoring upstream water flows and developing safeguards against potential unilateral water releases by China.
• Project Evolution: In 2017, the proposed Siang Upper Stage-I and Stage-II projects were merged into the larger SUMP proposal.
• Current Status: The project is currently at the Pre-Feasibility Report (PFR) survey stage and has not yet entered the construction phase.

LOCAL OPPOSITION AND KEY CHALLENGES

• Community Resistance: Members of the indigenous Adi community, farmers and local residents are opposing the project through protests and shutdowns.
• Displacement Concerns: Residents fear losing ancestral land, homes and traditional livelihoods, potentially becoming refugees within their own region.
• Cultural Heritage: The Siang River holds deep religious, social and cultural significance for indigenous communities, who regard it as a mother.
• Environmental Concerns: Large-scale dam construction may affect river ecosystems, biodiversity, forests and the region’s fragile Himalayan environment.
• Trust Deficit: Residents fear that completing the feasibility survey could create pressure for construction, despite government assurances that the project will not proceed without considering local consent.
• Expert Concerns: Experts argue that India must obtain detailed information about China’s upstream project rather than assuming that SUMP alone can counter its potential impacts.
• Government Assurance: The Arunachal Pradesh government has promised consultations, environmental and social impact assessments, compensation and rehabilitation if the project advances.
