Chinese green tech finds favor in water deficient areas

After being effectively implemented during construction of the main stadium for the FIFA World Cup Qatar 2022, China's cutting-edge water-saving technology is expected to witness wider applications in Qatar and related Central Asian countries.

As a crucial advancement in Ningxia Hui autonomous region's efforts to enhance irrigation efficiency, the smart wind-solar complementary water-saving irrigation technology is fully self-developed by Ningxia University. Central to the technology is the use of wind and solar energy to pump water, coupled with comprehensive smart control through the internet of things, said Sun Zhaojun, a professor responsible for the project at the university, during the 11th China-Central Asia Cooperation Forum in Yinchuan, Ningxia, last month.

The system utilizes underground infiltration irrigation, delivering water and nutrients directly to the roots of crops, thereby significantly reducing evaporation losses. In this regard, it boasts a water-saving efficiency exceeding 30 percent compared to existing international methods.
