Climate change may lead to a quarter reduction in corn yield by 2030

The latest research results recently released by the National Aeronautics and Space Administration (NASA) and the International Institute for Applied Systems Analysis and other institutions show that due to the damage of climate change to traditional weather patterns, the global per unit area yield of corn may be reduced by nearly a quarter by 2030. Compared with previous similar studies, the decline time of corn yield was earlier.

The report said that rising temperatures and changes in rainfall will make it more difficult to grow corn in the Americas, West Africa and China. Corn is the main forage crop in the world.

However, the unit yield of wheat may increase by 7% in the same period, because the temperature rise expands the area suitable for wheat planting. The increase of carbon dioxide content in the atmosphere will also make the unit yield of wheat crops better than that of corn, but this may be at the expense of the nutritional value of wheat.
