It is expected that 60% more rice should be produced in 2030 than that in 1995. Currently, 1 ha. for rice production provides food for 27 people. By 2050, 1 ha. will have to support 43 people.

据估计，2030年全球水稻产量应比1995年增加60%以上才能基本满足人类需求。目前每公顷所产稻谷能养活27人，但到2050年，每公顷所产稻谷必须要养活43人才行。

If 50% of the conventional rice is replaced by hybrid rice, and estimating on a 2 t/ha yield advantage of hybrid rice, it is estimated that the total rice production in the world will be increased by another 150 million tons, which can feed 400 million more people each year.

如果全球有一半的常规水稻面积改种杂交水稻，按每公顷增产2吨稻谷估算，则全球可增产1.5亿吨粮食，这相当于每年可多养活4亿人。
