尽管马铃薯已经是世界几十亿人的重要粮食作物,但是就世界持续增长的粮食需求来说,马铃薯的生产潜力还远远没有开发出来。从产能来说马铃薯是世界第五大作物,但是过去20年来,马铃薯产能的增加仍然没有让其赶上其他作物诸如玉米和水稻。过去20年马铃薯产量的增长主要来自亚洲和非洲,这两个地区的人口也是增长最快的。相对于亚洲与非洲地区马铃薯种植面积的惊人增长,欧洲与北美洲的种植面积却在下降。俄罗斯在世界马铃薯消费层面占有很大比重,但是由于人口在下降,其他食品消费量的增加,马铃薯的产出也在下降。
Although the potato is already an important food crop for billions of people in the world, the potential for potato production is far from being developed for the world’s growing food needs. Potato is the fifth largest crop in the world in terms of capacity, but the increase in potato production over the past two decades has not kept it from catching up with other crops such as corn and rice. The growth of potato production over the past two decades mainly comes from Asia and Africa, where the population is also the fastest growing. Relative to the spectacular growth of potatoes in Asia and Africa, the area planted in Europe and North America is declining. Russia accounts for a large share of world potato consumption, but potato output is also declining due to declining population and rising consumption of other foods.
