          Assessment experts harvest third-generation hybrid rice grown in the experimental field in Hunan's Hengnan county on Nov 2, 2020. Hybrid rice was listed among this year's Global Top Ten Engineering Achievements. Heterotic rice hybrids with high yield, disease resistance, and good quality have been developed by using male sterile lines as a genetic tool. In 2020, the third generation of hybrid rice developed by Chinese scientists set a new record with an annual yield of 22.96 metric tons per hectare of double-cropped rice. The successful development and large-scale promotion of hybrid rice is a great breakthrough in crop science and technology and provides an important foundation for global food security. [Photo by Zhou Wei/for chinadaily.com.cn]

          The journal Engineering is a publication of the Chinese Academy of Engineering. The list's creation involved nominations and recommendations by engineers and technicians around the globe, numerous public surveys and final screening by the selection committee.

          On Tuesday, the academy's Center for Strategic Studies and global analytical firm Clarivate published their Engineering Fronts 2021 report. The document, published annually since 2017, selected a total of 186 research and development frontier topics for nine broad engineering categories, ranging from agriculture to engineering management.

          Zhong Zhihua, vice-president of the CAE, said engineering and technology is a major support for socioeconomic growth and mankind's pursuit of sustainable development.

          "As our country enters a new developmental phase, we urgently need to accelerate our pace of innovation in engineering and technology and improve the quality of our innovation," he said, adding this will require scientific insight on new emerging engineering frontiers to guide future development.
