How could upstream control of Himalayan rivers affect Uttar Pradesh's water resources?
Upstream control of Himalayan rivers may disrupt agricultural supply in Uttar Pradesh The control exercised by upper riparian states over the Himalayan source region is being used as strategic leverage, potentially leading to altered water flows in major transboundary river systems like the Ganges-Brahmaputra-Meghna (GBM) basin. Since the GBM basin supports over a billion people and contributes over 40% of India’s GDP, changes in flow or data withholding could impact the agricultural operations and water availability in states like Uttar Pradesh. This risk is compounded by climate change, which is already causing prolonged droughts and erratic water cycles across the region.

How it reaches Uttar Pradesh
-
India suspended the 1960 Indus Waters Treaty following the 2025 Pahalgam attack, a move that the Court of Arbitration ruled impermissible. Meanwhile, Afghanistan's Kabul-Kunar basin remains contested with Pakistan, leaving downstream communities exposed without broad water-sharing agreements. The 1996 Ganges treaty is set to expire in December 2026.

China controls a large part of the Tibetan plateau, which is the origin of major rivers in South Asia. China is increasingly transforming this control into strategic leverage by building dams and withholding hydrological data during periods of tension.

The construction of large dams, such as China’s 60-gigawatt Medog Hydropower Station on the Yarlung Tsangpo, and the withholding of hydrological data by China, directly interfere with the flow of shared rivers that feed into the Ganges-Brahmaputra-Meghna basin. This basin is critical for over a billion people in South Asia.

The Ganges-Brahmaputra-Meghna basin is a densely populated region, and over 40% of India’s GDP is generated by this basin. As a major state within this basin, Uttar Pradesh is dependent on these river systems, making it vulnerable to changes in water availability or flow caused by upstream interventions.

The facts so far
As reported. Each one links to where it comes from.
- Over a billion people rely on the Ganges-Brahmaputra-Meghna and Indus basins in South Asia.eurasiareview.com
- Over 40% of India’s GDP is generated by the Ganges-Brahmaputra-Meghna basin.eurasiareview.com
- China began building the 60-gigawatt ‘Medog Hydropower Station’ on the Yarlung Tsangpo in July 2025.eurasiareview.com
- The Indian Ministry of Water Resources revealed that no information on hydrological data or hydrological structures has been shared by China with India since 2022.eurasiareview.com
Why it matters
The stakes for Uttar Pradesh and the wider region are tied to the fundamental resource of agriculture and water security. Since the GBM basin is responsible for a significant portion of India's economic output, any disruption to the water supply or flow patterns could directly threaten agricultural productivity and the livelihoods of the densely populated states within the basin.
This situation reflects a broader geopolitical trend where upper riparian states, particularly China, are using their geographic advantage over the Himalayan source region as an instrument of coercive statecraft. This tension is exacerbated by climate change, which is already making transboundary water management more difficult due to prolonged droughts and erratic monsoon patterns.
