An answer to the growing food crisis?
Though the price of grains has receded in recent months from historic highs, grains are still far more expensive than they were just two years ago. The United Nations agency continues to strongly encourage countries to diversify into potato production...Also, did you know the UN has named 2008 the official year of the potato? Me neither.
Potatoes are a good source of protein, starch, vitamins and nutrients like zinc and iron. As a crop, they require less energy and water to grow than wheat, taking just three months from planting to harvest. Since they are heavy and do not transport well, they are not generally traded on world financial markets, making their price less vulnerable to speculation. They are not generally used to produce biofuels, a new use for food crops that has helped drive up grain prices. When grain prices skyrocketed, potato prices remained stable.
Beyond that, potato yields can be easily increased in most of the world, where they are grown inefficiently and in small numbers.
