Global vulnerability to a wheat crop failure may have (at least) three interesting implications.
Massive famine could induce large population migrations, with the implication of extensive disruption of existing states.
Famine might damage government stability in poorer states, perhaps due to food riots or other disruptions.
From an investment perspective DBA (DB Powershares, agriculture, with 25% each of corn, wheat, soybeans and sugar might start getting interesting. (No established uptrend yet.)
The Ug99 fungus, called stem rust, could wipe out more than 80% of the world's wheat as it spreads from Africa, scientists fear. The race is on to breed resistant plants before it reaches the U.S.
The spores arrived from Kenya on dried, infected leaves ensconced in layers of envelopes.
Working inside a bio-secure greenhouse outfitted with motion detectors and surveillance cameras, government scientists at the Cereal Disease Laboratory in St. Paul, Minn., suspended the fungal spores in a light mineral oil and sprayed them onto thousands of healthy wheat plants. After two weeks, the stalks were covered with deadly reddish blisters characteristic of the scourge known as Ug99.
Crop scientists fear the Ug99 fungus could wipe out more than 80% of worldwide wheat crops as it spreads from eastern Africa. It has already jumped the Red Sea and traveled as far as Iran. Experts say it is poised to enter the breadbasket of northern India and Pakistan, and the wind will inevitably carry it to Russia, China and even North America -- if it doesn't hitch a ride with people first.
"It's a time bomb," said Jim Peterson, a professor of wheat breeding and genetics at Oregon State University in Corvallis. "It moves in the air, it can move in clothing on an airplane. We know it's going to be here. It's a matter of how long it's going to take."
Though most Americans have never heard of it, Ug99 -- a type of fungus called stem rust because it produces reddish-brown flakes on plant stalks -- is the No. 1 threat to the world's most widely grown crop.
The International Maize and Wheat Improvement Center in Mexico estimates that 19% of the world's wheat, which provides food for 1 billion people in Asia and Africa, is in imminent danger. American plant breeders say $10 billion worth of wheat would be destroyed if the fungus suddenly made its way to U.S. fields.
Fear that the fungus will cause widespread damage has caused short-term price spikes on world wheat markets. Famine has been averted thus far, but experts say it's only a matter of time.
"A significant humanitarian crisis is inevitable," said Rick Ward, the coordinator of the Durable Rust Resistance in Wheat project at Cornell University in Ithaca, N.Y.
The solution is to develop new wheat varieties that are immune to Ug99. That's much easier said than done.
