Raising productivity, rather than expanding resources, has become the major source of growth in global agriculture. Higher productivity has helped make food cheaper and more abundant, and saved resources such as forests from being converted to cropland. However, large differences remain in productivity performance between countries. For example, between 1971 and 2013, U.S. agricultural productivity growth averaged about 1.5 percent a year.
Over the past few decades, China and Brazil have emerged among the world leaders in agricultural productivity growth. In Sub-Saharan Africa, on the other hand, agricultural productivity has been relatively stagnant. According to ERS research, strengthening the capacity of national agricultural research and extension systems has been a key factor in improving productivity growth.
Long-term investments in agricultural research were especially important to sustaining higher growth rates in large, rapidly developing countries like Brazil and India. Under-investment in agricultural research remains an important barrier to stimulating productivity. The broader environment—such as institutions, infrastructure, and economic and trade policies—has also played an important role in raising agricultural productivity in many parts of the world.
