     Deputy Agriculture Secretary Kathleen Merrigan sees an epidemic (流行病) sweeping across

     America's farmland. It has little to do with the usual challenges, such as flood, rising fuel prices

and crop-eating insects. The country's farmers are getting older, and there are fewer people standing in

line to take their place. National agricultural census (普查) figures show that the fastest-growing group of

farmers is the part over 65. Merrigan is afraid the average age will be even higher when the 2012 statistics are completed.

     Merrigan, a former college professor, is making stops at universities across the country in hopes of

encouraging more students to think about careers in agriculture. Aside from trying to stop the graying of

America's farmers, her work is made tougher by a recent blog posting that put agriculture at No. 1 on a

list of "useless" college degrees. Top federal agriculture officials are talking about the posting, and it has

the attention of agricultural organizations across the country.

     "There couldn't be anything that's more incorrect," Merrigan said. "We know that there aren't enough

qualified graduates to fill the jobs that are out there in American agriculture."

     In addition, a growing world population that some experts predict will require 70% more food

production by 2050, she said.

     "I truly believe we're at a golden age of agriculture. Global demand is at an all-time record

high, and global supplies are at all-time record lows," said Matt Rush, director of the Texas Farm

     Bureau. "Production costs are going to be valuable enough that younger people are going to have the

opportunity to be involved in agriculture."

     The Department of Agriculture has programs aimed at developing more farmers and at increasing

interest in locally grown food. The National Young Farmers' Coalition has also been pushing for state and

federal policy changes to make it easier for new farmers.

     Ryan Best, president of Future Farmers of America, has been living out of a suitcase, traveling

the country and visiting with high school students about careers in agriculture. The 21-year-old Best

hopes his message-that this is a new time in agriculture-will motivate the next generation to turn

around the statistics. "Never before have we had the innovations (创新) in technology which have

led to agriculture in this country being the most efficient it has ever been," he said. "There's really a place

for everybody to fit in."
