In 1992-2020, natural freshwater resources, including natural lakes, decreased by 53 percent.

The 285-kilometer Koshtepa canal, which is being built by the Taliban, receives 4-4.5 cubic kilometers or 12-13 percent of water from the Amudarya every year. This will cause water supply in Uzbekistan and Turkmenistan to drop from 80% to 65%. It was said that the fact that Afghanistan has not signed any international cross-border document complicates the negotiations.

According to the UN, by 2030, more than 3.3 billion people in the world may be deprived of clean water and sanitation. In half of the world's countries, freshwater ecosystems such as rivers, lakes and aquifers are being destroyed, rivers and lakes are drying up, and aquifers are being overexploited. This leads to a sharp decrease in the level of underground water every year.
