For high-income countries as a group, public agricultural research expenditures (adjusted for inflation) grew rapidly after 1960. However, growth slowed markedly in recent decades and has now turned negative.
In constant 2011 dollars, public agricultural R&D spending in these countries grew from $3.9 billion in 1960 to a peak of $18.7 billion in 2009, before declining to $17.5 billion by 2013 (the latest year with complete data). This decline in public R&D spending marked the first sustained fall in agricultural R&D investment by these countries in 50 years, and was most pronounced in the United States and Southern Europe. The United States continues to lead among high-income countries in public agricultural R&D spending, but the U.S. share of the total declined from 35 percent in 1960 to less than 25 percent by 2013.
