On Septenber 29,2019, two days before the 70th anniversary of the founding of the People's Republic of China, 89一year一old Yuan Longping was awarded the Medal of the Republic, the country's highest honor for his extraordinary contribution to the nation's food security, the development of agricultural science, and global food supply. ^t4A tiny grain could either save a country or bring it down. The importance of fcx)d security should never be underestimated,'' said Yuan, academician of Chinese Academy of Engineering.

The 2019 State of Food Security and Nuiridon in the World report shows that over 820 m山ion people are suffering from hunger and the world is facing huge challenges in achieving the sustainable development goal of zero hunger by 2030. According to the UN's Food and Agriculture Organization, there are four factors in food security: physical availability of food, economic and physical access to food, food use, and stability of the other three factors over time. Between 1979 and 2005, China received fcx)d aid from the UN World Food Program(WFP) which benefited over 30 million people nationwide. Starting from 2016, however, the partnership between China and the WFP witnessed a total transformation: China turned from a major aid recipient to a leading aid donor, supporting millions of malnourished(营养不良的)people beyond its borders.

Innovation(仓4新)in science and technology is one of the driving forces behind this change. Yuan is considered a pioneer in the field of food science and technology. He has dedicated himself to the research, application and promotion of hybrid rice for decades. The super hybrid rice that his team cultivated can yield nearly 18.1 ton per hectare, setting a new world record. Hence, Yuan is regarded as the ^father of hybrid rice."

"Food safety is of very importance to the national economy and people's livelihood. As an agronomist, I felt that I should focus on this area,'' Yuan told CGTN. "My biggest hope is to make sure that the 'rice bowl' is firmly held in our own hands so that we, as a country, can feed ourselves.
