WAPO story.
The gist:
The Chinese government has begun ramping up research, production and training related to the humble spud, and hopes are high that it could help alleviate poverty and serve as a bulwark against famine.
The challenge of feeding a growing nation on a shrinking supply of arable land while confronting severe water shortages has long been a major concern here. China has to feed one-fifth of the world's population on one-tenth of its arable land, and the nation's expanding cities are consuming farmland at breakneck speed. China estimates that by 2030, when its population is expected to level off at roughly 1.5 billion, it will need to produce an additional 100 million tons of food each year.
That statistical reality could change eating habits here. Potatoes need less water to grow than rice or wheat, and they yield far more calories per acre.
Makes you wonder why the Irish got so heavy into potatoes, because there's no shortage of water there. Must be the tough growing season.
But the pattern is clear enough: cut back on water-intensive crops and move into more hardier fare (rice to potatoes). Obviously, rice isn't going anywhere, but as one Chinese ag expert put it, "Rice, wheat, corn -- we've gone about as far as we can go with them. But not the potato."
Some perspective on this shift: China actually ALREADY produces and consumes more potatoes than any other in the world. But when it comes to consumption, because we're talking such a huge population, the Chinese lag in per capita terms, eating only one-third the amount of potatoes that Russians do and two-thirds the amount Americans eat.
If I could get every Chinese to eat a potato a day . . ..
