The global population is forecast to reach nine billion by 2050 and a new United Nations report says climate change is threatening the world's three main crops.

Researchers are warning that rising global temperatures could see a shift in the world's traditional staples and who grows them. They predict that maize, wheat and rice will decrease in many developing countries - forcing farmers to replace them with crops more resistant to heat, drought and flooding.

The prediction, if true, would put more pressure on a world already facing a potential crisis over global food security.
