# Quantifying Drought Sensitivity Changes in U.S. Maize Yields</a> — NASA Harvest

> A study published this month in Nature Food by Stanford researchers including David Lobell examines how U.S. maize yields respond to drought. It finds that current yield-gain strategies work best in ideal weather and are increasingly sensitive to worsening drought. Yield sensitivity to water storage in the Corn Belt has risen 55% since 1999.

## Why it matters

Rising drought sensitivity raises the cost of maintaining yields under climate stress, a long-run supply risk for corn and the feed grains built on it. It is a research finding rather than a near-term supply shock, so the direct price effect is limited.
