Growing your own wheat really isn't an option. You have to grow A LOT of it. Second, I wouldn't worry too much about the fungus itself. The areas they are affecting are dealing with different wheat than what we use here in America. Most of our crops have been genetically designed to resist many fungi. Not to say it would resist this one, however, the infrastructure is well in place to quickly adapt the plant to fight off the fungus. We have been doing it for years.
With that said, there is a vast amount of land that goes cropless due to subsidizing that can be opened up. There are many farms in recent years that have just gone out of business because they cannot compete with corporate farming. My hometown in upstate New York used to boast about a hundred farms when I was a child; there are four left now. There are many fields that just lay dormant. When corn prices reach a level where it will be lucrative to fire them up again, don't worry, it will happen. The same applies to wheat.
People tend to forget that much of America used to be farming orientated. Heck, a good portion of Manhattan was farmland at one point.
When one takes a plane ride over the country and looks down, your fears of food shortages should gently melt away.
With all that being said, I do agree with Ky on the issues of ethanol and restrictive environmental policies have done a fair share of harm to this country. The pipe dream that we could all be driving corn fed cars one day is ludicrous.
I would be interested to know if this fungus has had any affect on Teff, a common grain used in the part of the world currently suffering from it. I have been very interested to try this, just haven't had much time lately.
