In the Sahara Desert of Harsh, fresh green fresh animal feed mats are unlikely to be seen, but a project of the United Nations World Food Program (WFP) is helping crops thrive in unexpected places. Use specially constructed hydroponic systems.
The project is part of the H2Grow program, which addresses hunger in arid regions and helps disadvantaged communities become more self-sufficient by ensuring food resources. With the help of agricultural technology systems, it is hoped that communities living in the desert can overcome short food.
Nina Schroeder, head of the WFP's scale-up promotion for innovation accelerators, said H2Grow's secret lies in hydroponics, a technique that uses up to 90% less water than traditional agriculture. Even better, hydroponic agriculture does not require large amounts of land or depends on the season. As long as you have the right basic ingredients (seeds, water, light and nutrients, photoelectric level sensors), crops can grow throughout the year. The application of photoelectric level sensor in hydroponic system not only saves water in the desert, but also keeps the plant in a state of water, avoiding water shortage in plants.
