Rice yields plummet and arsenic rises in future climate-soil scenarios

Rice is the largest global staple crop, consumed by more than half the world's population—but new experiments from Stanford University suggest that with climate change, production in major rice-growing regions with endemic soil arsenic will undergo a dramatic decline and jeopardize critical food supplies.  These experiments exploring rice production in future climate conditions show rice yields could drop about 40 percent by 2100—with potentially devastating consequences in parts of the world that rely on the crop as a basic food source. What's more, changes to soil processes due to increased temperatures will cause rice to contain twice as much toxic arsenic than the rice consumed today. The research was published Nov. 1 in Nature Communications.  Read more....
