Why California Growers Should Start Taking Wildfire Risk More Seriously

California agriculture is no stranger to adversity, but one growing threat has become impossible to ignore: wildfire. With climate change fueling longer fire seasons and drier conditions, California’s farmlands — especially those near wildland areas — are becoming increasingly vulnerable. While nut orchards may not be the primary ignition point, the agricultural industry as a whole cannot afford to ignore the rising risk.

How Wildfires Threaten Agricultural Productivity

Wildfires don't just devastate forests or rural communities — they directly affect California farms. The smoke alone can wreak havoc on crops. Research from the University of California-Davis shows that extended exposure to wildfire smoke can reduce photosynthesis in trees and lead to yield losses of 15% to 50%, depending on the crop and intensity of smoke exposure.

Ash fallout and poor air quality also impact harvesting timelines and worker safety, creating both immediate and long-term disruptions for growers. For grape vineyards and rangeland crops in particular, wildfires have caused major setbacks in both production and marketability in recent years.

Climate Change and Drought: A Dangerous Combo

Ongoing drought conditions and rising temperatures are increasing fuel loads and lowering humidity, creating perfect storm conditions for fire outbreaks. Even areas that historically saw minimal fire activity are now facing new challenges.

Many growers are beginning to realize that proactive fire prevention must become part of the overall operational strategy — not just for environmental compliance, but to safeguard their livelihoods.

Fire-Smart Ag Practices and State Support

Fire breaks, cover cropping, proper vegetation management, and equipment safety checks are just a few measures that can reduce fire risk on ag lands. In some regions, growers are now required to develop fire mitigation plans in accordance with state and local regulations.

The California Department of Food and Agriculture (CDFA) has stepped in with support — offering funding, technical guidance, and even insurance options to help farmers adapt.

Looking Ahead

The question isn’t if California agriculture will be affected by wildfires — it’s how prepared the industry will be when it happens again. From smoke disruption to crop loss and infrastructure damage, the ripple effects are real. For growers across all commodities, integrating fire prevention into day-to-day operations is quickly becoming a best practice — and a necessary one.
