An article in the Amber Waves magazine draws from a recently released report, Agricultural Productivity Growth in the United States: Measurement, Trends, and Drivers. This report examines changes and trends in U.S. agricultural inputs (e.g., land and labor), output (e.g., crops and livestock), and productivity over the last six decades and the drivers behind productivity changes.
The link to the magazine article is here: U.S. Agricultural Productivity Growth: The Past, Challenges, and the Future.
The main findings of the report are that between 1948 and 2011, U.S. agricultural output grew at 1.49 percent per year. With little growth in total input use during that period, the extraordinary performance of the U.S. farm sector was driven mainly by productivity growth, at an annual rate of 1.42 percent.
