Recently, India raised concerns over China's approval of the world's largest hydroelectric dam on the Brahmaputra, spurring the planning of India's Siang Upper Multipurpose Project. 

• About: 
  • It is located in the Upper Siang District, Arunachal Pradesh, near the Siang River (a major tributary of the Brahmaputra River). 
  • The Siang River, originating near Mount Kailash in Tibet as the Yarlung Tsangpo, flows eastward for over 1,000 km.  
    • It forms a horseshoe bend around Namcha Barwa peak before entering Arunachal Pradesh.  
      • In Assam, it merges with the Dibang and Lohit rivers to become the Brahmaputra. 
• Strategic Importance for India: 
  • Designed to counter the impact of China's hydroelectric projects on the Yarlung Tsangpo (Brahmaputra), which could affect India's water security. 
  • Reduces the risk of downstream flooding, especially due to upstream water releases by China. 
  • The project will have an installed capacity of 11,000 MW, making it a significant source of hydroelectric power. 
  • Ensures year-round river flow, especially during lean seasons, improving water availability and supporting agriculture. 
  • However, many residents of the Adi tribe in Upper Siang and Siang districts fear losing their farmlands and homes due to the proposed project.
