Global crop yields are stagnating


Source
"A University of Minnesota study recently published in the journal Nature found that a significant share of the world’s crop-growing regions are seeing growth stagnate, slow or even collapse. They published three other maps; see the others and why they think it’s so important to 'sound the alert; here."

There are nearly a billion people in the world today who go to bed hungry, our of a total world population of 7.1 billion. It is estimated that the world population will grow to about 10 billion by the end of the century. We are also stressing agricultural production through environmental degradation and climate change. People are also demanding more protein in their diets and especially more meat and more beef, which require lots of grazing land and feed production.

Those who oppose the application of biotechnology in agricultural research and crop improvement may be asked to explain where they think the new varieties needed to increase yields are going to come from. Sure there are risks from introducing new varieties, but the risks of not restoring worldwide yield improvement are very great and very real.
