‘Borrowed time’: crop pests and food losses supercharged by climate crisis

Heating means pests breeding and spreading faster, warn scientists, with simplified current food system already vulnerable

How climate breakdown is putting the world’s food in peril – in maps and charts

The destruction of food supplies by crop pests is being supercharged by the climate crisis, with losses expected to surge, an analysis has concluded.

Researchers said the world was lucky to have so far avoided a major shock and was living on borrowed time, with action needed to diversify crops and boost natural predators of pests.

The key global crops, wheat, rice and maize, are expected to see the losses to pests increase by about 46%, 19% and 31% respectively when global heating reaches 2C, the scientists said.
