Sources of Growth in Agricultural Output: High-Income Countries, 1961-2016
In the U.S., agricultural output has increased by 36 percent since 1982. 2 At the same time, the total amount of annual soil erosion has decreased by 44 percent, due to wide-spread adoption of advanced seed technologies, precision agriculture, and water management practices. As a result, the amount of soil erosion per unit of agricultural output has decreased by 60 percent.
Improvements in animal breeding, feed efficiency, manure management, and animal care make it possible for U.S. livestock producers to provide the world with nutritious meat, milk, and eggs with significantly fewer GHG emissions per unit of output. In Latin America, India, and China, GHG emissions per unit of livestock production are two to 10 times higher than in the U.S.
