84 percent of Iran's total area is either dry or semi-dry, while only only 16 percent of the country is humid and semi-humid, Deputy Energy minister of Iran, Sattar Mahmoudi said, Mehr news agency reported.
Speaking about the renewable water resources in Iran, he named the number of 130 billion cm, 92 billion cm of which are underground water resources.
Mahmoudi added that there are about 609 plains in Iran, and 253 of those are in such condition that it is impossible to get water off of them.
Iran continues to have struggles with droughts and dry climate. In the recent years, the country has experienced several droughts in recent years, especially in the south where it gets hit by violent sand storms that engulfed several cities.
Sand storms particularly enter Iran from neighboring Iraq where desertification has increased over the last two decades due to wars.
