Dust on the Rise: A Growing Threat to California Agriculture

A new study out of California is drawing attention to a growing challenge in agriculture: dust storms. Researchers from several University of California campuses collaborated on the report “Beyond the Haze: A UC Dust Report on the Causes, Impacts, and Future of Dust Storms in California.” It’s designed to help policymakers understand and address the risks dust poses to health, infrastructure—and farming.

As California’s climate shifts, experts expect changes in rainfall, soil moisture, and winds—all factors that can increase dust. While some ag practices may contribute to dust emissions, the report emphasizes that producers are also among the most affected.

Dust storms can damage plants, reduce crop yields by interfering with photosynthesis, and even pose risks to livestock. Fine dust particles can harm the health of the outdoor workforce, and studies link even low levels of dust to decreased labor productivity.

With California serving as the nation’s top ag producer, the stakes are high. The report offers strategies to reduce dust impacts—aiming to protect both the agricultural economy and the people behind it.
