Hydroponics Boost Food Production In Indonesia

SURABAYA, INDONESIA - JUNE 18: Indonesians check the sprouted plants in a hydroponics system on June 18, 2021 in Surabaya, Indonesia. Hydroponics enable people to grow food without soil and natural light, using blocks of porous material where the plants' roots grow, and artificial lighting such as low-energy LED. They can save water and produce safe food, either indoors or outdoors, in a world with increasingly scarce resources. The method also eliminates the need for fertilizers and can be used inside climate-controlled greenhouses which can reduce water usage by up to 90 percent. Hydroponic greenhouses can be used efficiently in arid climates and have a lower environmental impact. (Footage by Robertus Pudyanto/Getty Images)
