According to Reuters, while wheat and rice prices surge, the potato is being rediscovered as a nutritious crop that could cheaply feed an increasingly hungry world.

Potatoes, which are native to Peru, can be grown at almost any elevation or climate: from the barren, frigid slopes of the Andes Mountains to the tropical flatlands of Asia. They require very little water, mature in as little as 50 days, and can yield between two and four times more food per hectare than wheat or rice.

"The shocks to the food supply are very real and that means we could potentially be moving into a reality where there is not enough food to feed the world," said Pamela Anderson, director of the International Potato Center in Lima (CIP), a nonprofit scientific group researching the potato family to promote food security.
Like others, she says the potato is part of the solution.

The potato has potential as an antidote to hunger caused by higher food prices, a population that is growing by one billion people each decade, climbing costs for fertilizer and diesel, and more cropland being sown for biofuel production.
To focus attention on this, the United Nations named 2008 the International Year of the Potato, calling the vegetable a "hidden treasure."

India has told food experts it wants to double potato production in the next five to 10 years. China, a huge rice consumer that historically has suffered devastating famines, has become the world's top potato grower. In Sub-Saharan Africa, the potato is expanding more than any other crop right now.

Some consumers are switching to potatoes. In the Baltic country of Latvia, sharp price rises caused bread sales to drop by 10-15 percent in January and February, as consumers bought 20 percent more potatoes, food producers have said.

The developing world is where most new potato crops are being planted, and as consumption rises, poor farmers have a chance to earn more money. The potato is already the world's third most-important food crop after wheat and rice. Corn, which is widely planted, is mainly used for animal feed.

Though most Americans associate potatoes with the bland Idaho variety, they actually come in some 5,000 types. Peru is sending thousands of seeds this year to the Doomsday Vault near the Arctic Circle, contributing to a gene bank for food crops that was set up in case of a global disaster.

Potatoes are a great source of complex carbohydrates, which release their energy slowly, and -- so long as they are not smothered with butter -- have only 5 percent of the fat content of wheat.

They also have one-fourth of the calories of bread and, when boiled, have more protein than corn and nearly twice the calcium, according to the Potato Center. They contain vitamin C, iron, potassium and zinc.
