Research investments help many countries sustain growth in agricultural productivity

Raising the productivity of existing agricultural resources—rather than bringing new resources into production—has become the major source of growth in world agriculture. Farm productivity is measured by total factor productivity (TFP), an index that takes into account the land, labor, capital, and material resources employed in farm production and compares them with the total amount of crop and livestock output. If total output is growing faster than total inputs, then the total productivity of the factors of production (i.e., total factor productivity) is increasing. Using the latest available data through 2016, agricultural productivity has risen steadily in most industrialized countries at between 1 and 2 percent a year since at least the 1970s. Since the 1990s, many developing countries as well as transition economies that belonged to the former Soviet bloc also have increased their agricultural productivity. Long-term research investments to develop new technologies have been especially important to sustaining higher agricultural TFP growth rates in large, rapidly developing countries such as Brazil and India. Institutional and economic reforms, combined with technological changes, have led to significant benefits for Chinese agriculture. Additionally, Russian agriculture rebounded after the early 1990s economic transition from a planned to a market-based economy, and the southern region of the country achieved notable productivity improvement. In contrast, under-investment in agricultural research remains an important barrier to stimulating agricultural productivity growth in Sub-Saharan Africa.
