Genetically Modified Seed Use is Up in the U.S.

The United States Department of Agriculture has released a new report on the adoption of herbicide tolerant and insect resistant crops since their introduction in 1996.

According to the report, the percentage of genetically modified (GM) seed within the U.S. corn crop nearly doubled over the past 10 years, from less than half of the total planted corn acres in 2004 to 93 percent this year, up from 90 percent last year.

The report includes these three stats:

· GE soybean is 94 percent of soybean hectarage in the US in 2014 from 93 percent in 2013.
· GE corn is 93 percent of all corn planted in the US, up from 90 percent in 2013.
· GE cotton is 96 percent of all cotton grown in the US, up from 90 percent in 2013.

Global Productivity Growth of Agriculture Developing vs. Developed

Productivity growth in agriculture enables farmers to produce a greater abundance of food at lower prices, using fewer resources. A broad measure of agricultural productivity performance is total factor productivity (TFP). Unlike other commonly used productivity indicators like yield per acre, TFP takes into account a much broader set of inputs—including land, labor, capital, and materials—used in agricultural production. ERS analysis finds that globally, agricultural TFP growth accelerated in recent decades, largely because of improving productivity in developing countries and the transition economies of the former Soviet Union and Eastern Europe.

During 2001-2010, agricultural TFP growth in North America and the transition economies offset declining input use to keep agricultural output growing. By contrast, declining input use in Europe offset growing TFP, resulting in a slight decline in agricultural output over the decade. In most regions of the developing world, improvements in TFP are now more important than expansion of inputs as a source of growth in agricultural production. Sub-Saharan Africa is the only major region of the world where growth in agricultural inputs accounts for a higher share of output growth than growth in TFP.
