Curbing air pollution could help crops thrive

Controlling air pollution could help curb projected declines in global food supplies, a new study says, suggesting policymakers should consider both climate change and ozone pollution in efforts to ensure the world has enough food.

Scientists have largely neglected the interactions between rising temperatures and ozone pollution, which is known to damage crops. But the complex linkages can be significant, said the study, published in the latest issue of the journal Nature Climate Change.

It explored the global production of four food staples - rice, wheat, corn and soy - finding that effects will vary between regions, and some crops are more strongly affected by one of the two factors.
