Strategic and Environmental Concerns Over Siang Upper Multipurpose Project in Arunachal Pradesh

Key Highlights & Summary 

• Fresh protests erupted in Arunachal Pradesh Siang valley against pre-feasibility surveys for the proposed 11,200 MW Siang Upper Multipurpose Project, leading to detentions under state prevention laws. 

• The indigenous Adi community expresses severe concerns regarding displacement, submergence of ancestral lands, loss of agricultural livelihoods, and cultural disruption. 

• Proposed with a dam height of 280-300 metres and live storage of 9.2 billion cubic metres, the mega project aims to generate power, regulate downstream flows, and mitigate flood risks.  

• The strategic imperative stems from countering China\'s upstream mega-hydropower developments, including its planned 60,000 MW dam on the Yarlung Tsangpo (Siang) in Tibet near the Indian border.  

• Security deployment and preventive detentions under the Arunachal Pradesh Unlawful Activities (Prevention) Act, 2014, have intensified public discontent and calls for transparent stakeholder dialogue.  

• Experts and civil society stress balancing national strategic water rights against local free, prior, and informed consent, while addressing hydrological safety risks.  

Essential Definitions 

• Siang Upper Multipurpose Project: A planned 11,200 MW mega-hydropower and water storage project on the Siang River in Arunachal Pradesh designed for power generation, flood control, and strategic water management.  

• Downstream Riparian Rights: The legal and operational rights of nations or regions situated downstream along a shared river system to receive natural water flows without harmful upstream alterations. 

• Transboundary River Hydrology: The study and management of water systems that cross international political boundaries, involving shared data, flood forecasting, and strategic water security. 

• Free, Prior, and Informed Consent (FPIC): A legal principle recognizing indigenous communities right to give or withhold consent for projects affecting their lands, livelihoods, and custom resources. 

Legal and Constitutional Framework

 • Article 246 (Seventh Schedule - List I, Entry 56): Authorizes Parliament to regulate and develop inter-State rivers and river valleys in the public interest. 

• Arunachal Pradesh Unlawful Activities (Prevention) Act, 2014: State preventive detention statute invoked by local authorities to maintain public order during local infrastructure demonstrations.  

• Fifth Schedule of the Constitution: Provides special constitutional protections and administrative frameworks for tribal areas to safeguard indigenous culture, land rights, and autonomy. 

• Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013: Mandates social impact assessments and fair rehabilitation for communities displaced by public infrastructure projects. 

Conclusion The Siang Upper Multipurpose Project underscores the complex intersection between regional strategic security and local tribal rights in India\'s borderlands. Ensuring sustainable border security and downstream water rights necessitates building transparent consensus with local indigenous communities alongside rigorous environmental impact assessments.
