Organic soils, for example, retain water better than those farms that employ conventional methods. "Increasing salt, drought or heat tolerance of our existing crops can move them a little but not a lot," said biologist Nina Fedoroff of Pennsylvania State University at the New America event.
Federal spending on organic agriculture has also grown in recent years.

More recently, Congress passed an $867 billion farm bill that includes funding for organic farming research. "You use a lot more water [in irrigation] because the soil doesn't have the capacity to retrain the water you use," noted farmer Fred Kirschenmann, president of Stone Barns Center for Food and Agriculture at the "Feeding the World While the Earth Cooks" event at the New America Foundation in Washington, D.C., on April 12. Younger Americans and those who report eating at least some organic food are more likely to believe organic produce provides health benefits.
