Traditional agriculture uses about 70 percent of the water on our planet. That’s alarmingly high number, especially when one considers how irreplaceably important the water is to all life surrounding us.
Fortunately, we have two significantly more water-efficient alternatives at our disposal. Hydroponics and aeroponics. The hydroponics is roughly 70 percent more efficient than old-fashioned water hogging while aeroponics is another 70 percent more efficient than hydroponics.
Thus, if we use aeroponics for agriculture, we can drop water usage (wastage) from 70 % to 6 % which would be quite a saving.
With the threat of water scarcity getting more serious every day, it’s hard to believe these technologies haven’t been widely adopted yet.
Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil. (The idea of growing food in water dates back, at least, to the Hanging Gardens of Babylon.)
Aeroponics is the process of growing plants by suspending them in mid-air, delivering food through a nutrient-rich mist.
