Famous scientist as he is, Yuan Longping considers himself a farmer. He grows what is called super hybrid rice. As a young man , Yuan Longping saw the great need for increasing the rice output. At that time, hunger was a disturbing problem in China. He wanted to increase rice harvests without expanding the area of the fields. In 1973, a special strain of rice made it possible to produce 20%more of the crop in the same fields. Thanks to his research , the UN has more tools in the battle to rid the world of hunger. Using his hybrid rice , farmers are producing harvests twice as large as before. He is now circulating his rice knowledge in less developed countries to increase their rice harvests and he wants to export his rice so that it can be grown around the globe. Though he has struggled for the past five decades, Yuan Longping is quite satisfied with his life. In his spare time, he enjoys listening to violin music , playing mah-jong , swimming and reading.
