On today’s episode of the AgNet News Hour, Rachel Nettleton, Executive Director of the Kern County Farm Bureau, joined Nick Papagni to discuss a growing threat to California’s agricultural water infrastructure, mounting production costs and the challenges facing one of the nation’s most productive farming regions. The conversation also explored crop losses, farmland development, agricultural technology and efforts to encourage the next generation of farmers.
One of the most urgent concerns facing Kern County is the spread of invasive golden mussels, which are threatening irrigation systems and other water infrastructure throughout California.
Nettleton explained that the small freshwater shellfish attach themselves to pipes, pumps and screens, forming dense clusters that can restrict water movement and create costly maintenance problems.
According to Nettleton, approximately $6 million had already been spent addressing the problem in local water districts earlier this year. Additional estimates projected $24 million in near-term control expenses and another $36 million in ongoing remediation.
Kern County requested a statewide emergency declaration to help secure funding and streamline permitting, but Nettleton said the request was denied in late October.
Beyond the invasive species threat, Nettleton discussed the financial pressures facing growers despite Kern County’s impressive agricultural production.
The county’s recently released 2025 crop report valued agricultural production at approximately $8.9 billion, an increase of roughly 12% from the previous year. However, that production value does not necessarily translate into profitability for individual farmers.
Nettleton pointed to rising regulatory compliance costs, expensive fuel and labor, and the difficulty of keeping multigenerational farming operations financially sustainable.
Weather-related losses have created additional challenges. Nettleton said Kern County cherry growers experienced crop losses exceeding 40% following unusually warm March temperatures, while pistachio producers also suffered significant damage during bloom and pollination.
The conversation also examined the continuing conversion of agricultural land into residential development around Bakersfield.
Nettleton acknowledged the economic benefits of growth but expressed concern about losing productive farmland and the family histories associated with those properties.
Despite the challenges, she remains optimistic about the industry’s future.
Through the Farm Bureau’s Young Farmers and Ranchers program and its annual Farm Day in the City, the organization is working to introduce younger generations to agricultural careers and the importance of food production.
Nettleton said the educational event typically reaches more than 5,000 students over two days.
As California growers prepare for 2027, Nettleton encouraged agricultural producers to become more involved in sharing their experiences with consumers and policymakers.
“We have to share our story,” Nettleton said. “We can’t let other people share it for us.”
