gricultural science policy in the United States has profoundly
affected the growth and development of agriculture worldwide, not
just in the A United States. Over the past 150 years, and
especially over the second th half of the 20 Century, public
investments in agricultural R&D in the United States grew
faster than the value of agricultural production. Public spending
on agricultural science grew similarly in other more-developed
countries, and c- lectively these efforts, along with private
spending, spurred agricultural prod- tivity growth in rich and poor
nations alike. The value of this investment is seldom fully
appreciated. The resulting p- ductivity improvements have released
labor and other resources for alternative uses-in 1900, 29. 2
million Americans (39 percent of the population) were - rectly
engaged in farming compared with just 2. 9 million (1. 1 percent)
today- while making food and fiber more abundant and cheaper. The
benefits are not confined to Americans. U. S. agricultural science
has contributed with others to growth in agricultural productivity
in many other countries as well as the Un- ed States. The world's
population more than doubled from around 3 billion in 1961 to 6. 54
billion in 2006 (U. S. Census Bureau 2009). Over the same period,
production of important grain crops (including maize, wheat and
rice) almost trebled, such that global per capita grain production
was 18 percent higher in 2006.
