“Although farming productivity has increased, nowadays farmers are being asked to do more than produce more food for a growing world population," said Julia Kornegay, chair of the committee that wrote the report.
“If farmers are going to meet future demands, the U.S. agriculture system has to evolve to become sustainable and think broadly -- past the bottom line of producing the most possible."
Although farmers were said to be producing more food with less energy than 50 years earlier, external factors such as water tables, nitrogen pollution and oxygen-starved waterways had driven up costs.
The study outlined goals for a more holistic approach to US farming including satisfying human food, fiber, and feed requirements, and recommended enhancing resource bases and environmental qualities, while maintaining the economic viability of agriculture.
