The world must diversify its food production and consumption, or face damaging supply disruptions that could lead to suffering and social unrest, scientists warned Monday.

A new global study found the health and environmental benefits of transforming the way we farm would outweigh heavily the cost of doing so, with the authors urging governments to do more to support sustainable agriculture.

"A small disruption in supply really can do a lot of damage and leads to huge price increases," said Per Pharo of the Food and Land Use Coalition, the global alliance of economists and scientists behind the study.
