Zangmu Dam – The Zangmu Dam, built by China on the Yarlung Tsangpo (Brahmaputra in Tibet), has raised concerns over water flow into Arunachal Pradesh. Ecological Significance – The river supports rich biodiversity, including rare species like the Gangetic dolphin, and is vital for wetlands and forests in Arunachal Pradesh. Flooding & Erosion – During monsoons, the river swells rapidly, causing floods and soil erosion in Arunachal Pradesh, affecting settlements and agriculture. Cultural & Religious Importance – The Brahmaputra is considered sacred by local tribes and plays a key role in their religious and cultural traditions. Strategic Importance – The river’s proximity to the India-China border makes it crucial for security, and India closely monitors water-related activities in Tibet.
