Rice fields at risk from extreme rain due to climate change could threaten global food supply
A study led by researchers at Peking University in China suggests that extreme rainfall will significantly threaten global food production due to climate change and the accompanying extreme weather events.

[The study] used long-term weather observations and multi-level rainfall manipulative experiments to explore the magnitude and mechanisms of extreme rainfall impacts on rice yield.

Rainfall simulations across China showed that physical disturbance induced by extreme rainfall was the most critical yield determinant across 47% to 95% of rice sowing areas, accounting for approximately an 8% reduction in yield already, separate from the projected 8.1% reduction by the end of the century.

A substantial percentage of humans live in China, with more than 18% of all humans calling it home. Conditions that affect the food supply of China have wide-ranging impacts on economies, agriculture and water usage around the world.
