A Lifelong Devotion to Keeping People Fed

Yuan Longping is a Chinese agricultural scientist and educator, known for developing the hybrid rice varieties.

Yuan graduated from the Southwest Agriculture Institute in 1953 andbegan his teaching career at an agriculture school.

In the 1960s, when a serious food shortage sweptChina, Yuan decided to devote himself to studying how to increase the yields of rice. He then began a lifelong connection with rice.

Yuan succeeded in growing the world’s first high-yielding hybrid rice varieties in 1973, which could reach a yield of over 500 kg per mu (about 0.067 hectares), rising from the previous yield of only 300 kg per mu. For the next four decades, he continued to work on research and development of hybrid rice, achieving increasingly higher outputs. In 2020, hybrid rice developed by Yuan’s team achieved 1,500 kilograms per mu in two growing seasons, a new world record.

InChina, where rice is the main food for the majority of the 1.4 billion people, the planting area of hybrid rice has reached 16 million hectares, or 57 % of the total planting area of rice, helping feed an extra 80 million people a year.

Hybrid rice has also been grown in over 40 countries, including theU.S.,Brazil,India,Vietnam, thePhilippinesandMadagascar. The total planting area of the hybrid rice has reached 8 million hectares overseas.

Even after a great success, Yuan never held himself back from making new breakthroughs. In 2017, his team started to grow seawater rice inQingdao. The rice was designed to grow in saline-alkaline land and survive even after being completely in seawater. His team planned to develop a type of seawater rice that could be planted in 6.67 million hectares of saline-alkaline land acrossChinato boost the country’s rice harvest by about 20 %. In 2018, Yuan’s team was invited to plant the saline-alkaline tolerant rice in experimental fields inDubai, which achieved huge success. In June 2020, his team started to grow seawater rice on a farm at an altitude of 2,800 meters in northwestChina’sQinghaiProvince. The experiment succeeded.

Yuan had two dreams — to “enjoy the cool under the rice crops taller than men” and that hybrid rice could be grown all over the world to help solve the global food shortage.

Bill Gates on how to fight future pandemics

WHEN HISTORIANS write the book on the covid-19 pandemic, what we've lived through so far will probably take up only the first third or so.The bulk of the story will be what happens next.

I believe that humanity will beat this pandemic, but only when most of the population is vaccinated(接种疫苗）.Until then, life will not return to normal.

As the pandemic slows in developed nations,itwill accelerate in developing ones.Their experience,however,will be worse.In poorer countries,where fewer jobs can be done remotely,distancing measures won't work as well.The virus will spread quickly,and health systems won't be able to care for the infected.

Wealthy nations can help.But people in rich and poor places alike will be safe only once we have an effective medical solution for this virus,which means a vaccine.

My hope is that,by the second half of 2021,facilities around the world will be manufacturing a vaccine.If that's the case,it will be a history-making achievement: the fastest humankind has ever gone from recognizing a new disease to immunizing（免疫）against it.

Apart from this progress in vaccines,two other big medical breakthroughs will emerge from the pandemic.One will be in the field of diagnostics.The next time a novel virus crops up,people will probably be able to test for it at home.Researchers could have such a test ready within a few months of identifying a new disease.

The third breakthrough will be in antiviral drugs.We haven't been as effective at developing drugs to fight
