The more systematically collected data on the glaciers in Kyrgyzstan is from the 1960s. With preparation of a national climate change adaptation strategy and its adoption by the Government, Kyrgyzstan expects to gradually take related measures in the coming years. For example, future irrigation requirements remain to be assessed. In some countries, efforts have been made to assess the likely impact climate change will have on water resources in the major river basins. However, the limited results show a significant spread in predictions. For example, in 2004 the Islamic Republic of Iran and Turkmenistan completed the construction of the Dosti Dam on the Tejen/Harirud.
