Afghanistan’s Qosh-Tepa Canal Could Impact Kazakhstan’s Water Security
The construction of the Qosh-Tepa Canal in Afghanistan and its potential implications for Central Asia’s water security were central topics at the recent international conference, Water Security and Transboundary Water Use: Challenges and Solutions, held in Astana. Delegates from Turkey, Israel, Tajikistan, Kyrgyzstan, Afghanistan, and Turkmenistan convened to address the canal’s possible repercussions and broader issues of regional water distribution. Potential Threats to the Syr Darya Kazakhstan’s Deputy Minister of Water Resources and Irrigation, Aslan Abdraimov, warned that the Qosh-Tepa Canal could significantly reduce the flow of the Syr Darya River, with direct consequences for the already depleted Aral Sea. While Kazakhstan does not share a border with Afghanistan, the canal's impact is expected to ripple across the region. “No sharp fluctuations in water resources are expected in the near term, but in the long term, a reduction in the Syr Darya’s flow is inevitable,” Abdraimov stated. He emphasized that this would further strain the fragile water balance in the Aral Sea basin. The Aral Sea’s degradation has been ongoing for decades, largely due to the diversion of the Amu Darya and Syr Darya rivers for agricultural use, primarily for irrigating cotton and wheat fields. These diversions have contributed heavily to the sea’s dramatic shrinkage. Azamatkhan Amirtayev, chairman of Kazakhstan’s Baytak Party, expressed concern that the Qosh-Tepa Canal could divert 25-30% of the Amu Darya’s flow. “This means that Uzbekistan and Turkmenistan will receive less water. Consequently, Uzbekistan may draw more from the Syr Darya, leading to reduced water availability for Kazakhstan, potentially by 30-40%,” Amirtayev said. He urged for regional cooperation and scientifically informed policymaking to mitigate water losses. The Qosh-Tepa Canal and Its Regional Consequences The Qosh-Tepa Canal, under construction in northern Afghanistan, is designed to stretch 285 kilometers and span approximately 100 meters in width. Once operational, it is expected to irrigate over 500,000 hectares of farmland by diverting up to 10 cubic kilometers of water annually from the Amu Darya, roughly a quarter of the river’s average flow. Such a significant withdrawal could disrupt the hydrological balance across Central Asia. Reduced flows in the Syr Darya may accelerate the desiccation of the Aral Sea and exacerbate ecological degradation in Kazakhstan’s downstream regions. Experts at the conference underscored the urgency of strengthening regional water diplomacy and establishing new cooperative frameworks to ensure sustainable water usage and prevent environmental disasters. Hope for Dialogue Afghan representatives have previously signaled a willingness to engage in dialogue on water resource management. Observers suggest that joint initiatives in water management could play a key role in easing regional tensions and improving environmental outcomes. As the region faces mounting water stress due to climate change, population growth, and infrastructure development, coordinated action among Central Asian states and Afghanistan is increasingly seen as essential for long-term water security.
