Iran and Afghanistan have been in conflict concerning the distribution of water from the Helmand River. Recent events, including clashes between Iranian and Taliban troops along the border, have further escalated tensions between the two nations.
The Helmand River is main resource for both Afghanistan and Iran, supporting agriculture, livelihoods, and ecosystems in the region. Originating near Kabul in the Hindu Kush mountain range, the river flows for approximately 1,150 kilometres (715 miles) before emptying into Lake Hamun, which straddles the Afghanistan-Iran border.
Unfortunately, Lake Hamun, once the largest freshwater lake in Iran, has suffered immensely over time. Factors such as drought and the impact of dams and water controls have caused the lake to dry up, resulting in severe environmental and economic consequences for the region.
To regulate the allocation of river water, Iran and Afghanistan signed the Helmand River Treaty in 1973. However, the accord was not fully implemented, leading to ongoing disagreements and tensions. Iran has accused Afghanistan of violating its water rights, claiming that it receives significantly less water than agreed upon in the treaty. Afghanistan, on the other hand, attributes the reduced river water volumes to climatic factors such as decreased rainfall.
Iran and the Taliban have a complex relationship. While Tehran had cultivated good ties with the Taliban before their takeover of Kabul in 2021, incidents at the border have strained their interactions. The Taliban’s unwillingness to honour agreements regarding water rights has added to the tensions. The sustainable resolution of the water dispute requires closer collaboration and information sharing between officials and experts from both countries.
