Groan, I know, but use this one if you are tired of those Florida freeze examples:
A rare collision of ill-timed rain, marauding animals and a growing love affair between the Chinese middle class and the pecan has resulted in the worst pecan supply in recent memory. As a result, grocery store prices are up by about 30 percent ....
In 2012, the nation’s pecan orchards produced about 302 million pounds of pecans. This year, that number could drop by as much as 35 percent, according to industry officials. In Georgia, the nation’s leading pecan-producing state, the crop is expected to be about half of what it was last year. In South Carolina, some orchards succumbed completely.
The problem began with record rainfall last spring and summer. Pollination became difficult, and the moisture encouraged disease. Pecan growers sprayed their fields in record amounts, but it was not enough to fight off a disease called scab.
In Texas and Oklahoma, it was a summer drought that hurt the trees. Then came autumn’s heavy rain, which made the ground too wet to hold the heavy equipment that shakes nuts from trees and sweeps them up.
As a result, harvesting was sporadic, and the pecan supply was left wide open for feral pigs, which have become quite a problem in Texas, and for squirrels, which are always looking for a free nut. ...
The bad nut crop has a few other causes, one of which is the cyclical nature of pecans: Typically, if one year is good, the next year is not.
Last year, for example, Texas produced about 65 million pounds of pecans, said Larry Stein, a professor of horticulture at Texas A&M University. Most estimates indicate that this year will bring no more than 35 million pounds. ...
In the mid-2000s, the market for pecans in China began to grow rapidly. China now consumes more than a third of the American pecan crop, a development that followed the country’s inclusion in the World Trade Organization in 2001.
Scab, feral pigs, squirrels, China, Boo Radley? Could micro principles get any more interesting?
