NASA predicts major changes in crop production Today’s Video of the Day from NASA Goddard reveals how climate change is impacting crops on a global scale. The researchers expect that significant changes will take place in crop production within the next ten years.
The scientists used climate models to predict changes in twelve major crops worldwide. The results suggest that corn crops will decline by 24 percent. On the other hand, what production is expected to increase by 17 percent.
“What we’re doing is driving crop simulations that are effectively growing virtual crops day-by-day, powered by a supercomputer, and then looking at the year-by-year and decade-by-decade change in each location of the world,” explained study co-author Alex Ruane.
Study lead author Jonas Jägermeyr is climate change scientist and crop modeler at NASA’s Goddard Institute for Space Studies (GISS) and The Earth Institute at Columbia University in New York City.
“We did not expect to see such a fundamental shift, as compared to crop yield projections from the previous generation of climate and crop models conducted in 2014. A 20% decrease from current production levels could have severe implications worldwide,” said Jägermeyr.
