TEHRAN, Iran, Nov. 20
Tehran and Kabul have agreed upon a plan to measure the use of water at the joint border, said Ghasem Taghizadeh Khamesi, an official with Iran's Ministry of Energy.
"Afghanistan has agreed with the general plan that Iran has provided, which has to do with the measuring system for fair water use," he said.
Water from the Helmand River is in principle shared under a 1973 treaty, which assigned Iran 820 million cubic meters of water a year. But with Afghanistan at war for the past 40 years the supply has been erratic.
Helmand river runs through much of Afghanistan from its source in the mountains north of Kabul, feeding the Sistan wetlands in the border regions of the two countries. The issue has been an important part of bilateral negotiations between Iran and Afghanistan.
Khamesi said that it has been agreed that at the 21st joint meeting of the Helmand water commission, both Iran and Afghanistan will continue to review the issue.
