Fresh water makes up 2.5% of the total amount of water in the world. 2/3 of it consists of ice and glaciers. “The volume of used water resources is 40,700 cubic meters. km3, and 20% of them are located in hard-to-reach areas, 32900 km3 or ¾ falls on flood waters, and ¼ part or 12500 km3 of water can be used for sustainable water supply to the population. In the world for the year use 2.8 thousand. km3 of fresh water for agricultural needs. This is 70% of the world's fresh water consumption, or 7 times more than the water used in the world's industry.
