Study Warns Newly Developed Crop Varieties Can't Keep Up With Climate Change
Crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties.
A study says temperatures are rising faster than the development of crop varieties that can cope with a warmer world.
In Africa, researchers found that it can take 10-30 years before farmers can grow a new breed of maize.
By the time these new crops are planted, they face a warmer environment than they were developed in.
