LEE COUNTY, Fla.- ECHO, a local agricultural research organization, is hosting about 300 people from 30 countries in the effort to fight global hunger. The people are learning ways to get more food out of the ground in their home countries.

ECHO is stressing ways to better use resources for better crop yields. The people are meeting this week at a local hotel, and at ECHO"s farm in North Fort Myers. The group has 55 acres where it experiments with more than 350 varieties of fruits and vegetables.

"We emphasize low-cost, efficient ways to move water better to crops, things like that," says David Erickson, of ECHO.

He says this year's conference is attracting a lot more young people, and he likes that trend. He says the average age of a farmer in the U.S. is 58 years.   He says it's vital to bring in more young people, who can farm and also help people with community gardens and urban farming.
