Building Sustainable Food System is a Necessary Step

Global food production may need to double over the next century to feed a growing world population, writes Tim Radford - just as yields crops in major crop-growing areas fall due to higher temperatures. But there is another way: to build sustainability into our food production and consumption.

More than half of all the world's maize crops and around a third of all wheat and rice will be grown in regions vulnerable to climate change in the next 50 to 100 years, according to new research.

At the same time, the world's population will grow to 9 billion, and global food production will need to rise by from 60% to 110% by 2050 to keep up with demand.
