Origin, Course &amp; Tributaries<\/strong><\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Could Chinese Dams Affect the Brahmaputra in India?<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Hydrological Impact:<\/strong> The Chinese dams may alter natural water flow patterns, affecting seasonal water availability.\n<ul class=\"wp-block-list\">\n<li><strong>Example: <\/strong>Medog Hydropower Project (proposed 60,000 MW) near the \u2018Great Bend\u2019 of the Yarlung Tsangpo in Tibet.<\/li>\n\n\n\n<li>A sudden release of water or temporary water retention can exacerbate floods or worsen dry spells in Arunachal Pradesh and Assam, especially during the lean season.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Ecological Disruptions:<\/strong> Reduced sediment flow, altered flood regimes, and biodiversity loss.\n<ul class=\"wp-block-list\">\n<li><strong>Example:<\/strong> The Kaziranga National Park, home to the one-horned rhinoceros, depends on regular flooding of the Brahmaputra for ecological regeneration.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Strategic &amp; Geopolitical Risk:<\/strong> Gives China a perceived upper hand in water diplomacy; potential tool for coercion.&nbsp; Like during the<strong> 2017 Doklam standoff<\/strong>, China withheld hydrological data on the Brahmaputra, which it is obligated to share under a bilateral agreement.<\/li>\n\n\n\n<li><strong>Economic Consequences:<\/strong> Uncertainty in water flow can affect irrigation, agriculture, and hydropower generation downstream.\n<ul class=\"wp-block-list\">\n<li><strong>Example:<\/strong> Any disruption in Subansiri and Siang tributaries, where India has planned large hydropower projects (e.g., Lower Subansiri Hydro Project), can delay infrastructure timelines or reduce output.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Inter-State Tensions in India: <\/strong>Unpredictable flow from upstream may aggravate water-sharing conflicts between Indian states.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>China\u2019s Contribution Vs India\u2019s Share<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Multiple expert studies (e.g., by PK Saxena and Teerath Mehra) indicate that China contributes only 22\u201330% of Brahmaputra\u2019s annual discharge.<\/li>\n\n\n\n<li>70\u201378% of the river\u2019s flow is generated within India, primarily due to monsoonal rainfall and tributary inflows in Arunachal Pradesh and Assam.<\/li>\n\n\n\n<li>Hydrologically, China\u2019s control over the river\u2019s headwaters has limited influence on its overall flow in India.<\/li>\n\n\n\n<li>Even to address water scarcity, two river-linking projects have been proposed: the <strong>Manas-Sankosh-Teesta-Ganga Link<\/strong> and the <strong>Jogighopa-Teesta-Farakka Link<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Way Forward&nbsp;<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>India should conduct <strong>detailed scientific studies<\/strong> and develop an <strong>adaptive strategy<\/strong> to assess the impact of Chinese projects on the Brahmaputra.<\/li>\n\n\n\n<li>It must <strong>strengthen diplomatic efforts<\/strong> to access hydrological data and establish data-sharing protocols with China for early warnings and disaster preparedness.<\/li>\n\n\n\n<li>India can use forums like BIMSTEC, SCO, and Quad to internationalize the issue and press for sustainable and equitable transboundary river management.<\/li>\n<\/ul>\n\n\n\n<p><strong>Source
