Title: Technology for Subterranean Irrigation Ensures Drinking Water Supply

Forty per cent of the earth consist of arid climate zones. That is where water is always in short supply. Inefficient water use causes desertification, which is often a question of survival for the population of those countries. According to experts, by 2025 water will be a scarce commodity for one third of our planet. Eighty per cent of global water resources are needed for agricultural irrigation. By 2030, experts say, 20 per cent more regions will be in need of irrigation, and water consumption will go up by 14 per cent. Industrial output will increase threefold by then, water consumption will double. This trend calls for more innovative technologies for stabilizing water consumption, especially in arid zones.
 
The Karshi Engineering-Economic Institute is willing to look at these issues. Dr. Shuhrat Muradov is in charge of the Institute’s department of Environmental Protection and Ecology. He is a renowned expert in his field and has made a name for himself by publishing 320 scientific reports, two books on ecology, and ten patents. He is also the author of a special technology for integrated water management, which keeps drinking water safe while stabilizing water consumption in agricultural and industrial zones especially in arid regions. Under his leadership this technology was successfully applied in southern Uzbekistan– a region that drains vast quantities of water from the Amu Dary Basin. The process is simple yet effective: A special gas-hydrate technology using CO2 is used for desalination and demineralization. The soil is watered subterraneously through a drainage system from the ground water. By using naturally processed minerals such as Vermiculite, Perlite, etc. the soil is improved. Water can evaporate more efficiently. It condenses and forms very small pools of moisture that are gradually absorbed by the plants. The soil is aerated and solidified, which again offers protection from water and wind erosion. At the same time, water consumption is measured.
 
This technology has been successfully applied in Uzbekistan. It is efficient and affordable. One unit costs 50 euros and lowers irrigation demands in agriculture substantially. The minerals used for soil enrichment are purchased locally. This technology can be used in any arid zone anywhere in the world. By 2015, Uzbekistan will be using it nationwide. It lowers water consumption especially in industrial and agricultural regions. People in arid climate zones are guaranteed access to drinking water.





“This technology safeguards water supply for people in arid zones.“
