California SB 72: A guide for organic growers

California organic growers face growing challenges from drought, climate change, and water scarcity. Senate Bill 72 (SB 72), signed into law on Oct. 1, 2025, sets a new course for long-term water planning in the state.

SB 72 directs the California Department of Water Resources (DWR) to update the California Water Plan and establish statewide water-supply targets through 2050. Key measures include:

• Expanding recycled water, desalination and stormwater capture.
• Adding roughly 4 million acre-feet of new storage and 500,000 acre-feet of conservation capacity.
• Planning for a 10% reduction in water supply by 2040 due to climate change.

These initiatives aim to improve water reliability for farms and support sustainable agricultural systems.

Implications for organic growers

Enhanced water security: More reliable water resources benefit both annual and perennial crops.

Focus on efficiency: SB 72 encourages efficient irrigation systems, monitoring and conservation practices, which align with organic farming principles.

Supports sustainability goals: Proactive water management reinforces the organic ethos of resource stewardship and can enhance farm sustainability messaging.

Considerations

Long-term outlook: Many targets are planned for 2050, with interim updates by 2033. Immediate regulatory changes are limited.

Potential regulatory pressures: Future rules may affect groundwater use or water diversion, particularly in stressed regions.

Collaboration required: Success depends on coordination between growers, water districts, and state agencies. Organic growers are encouraged to engage early.

Steps for organic growers

• Connect with local water agencies to understand regional plans under SB 72.
• Review irrigation systems and practices to improve efficiency and resilience.
• Incorporate water stewardship into annual planning and organic system management.
• Participate in stakeholder processes, including public comment periods.
• Highlight water stewardship in marketing and certification narratives as a sustainability strength.

SB 72 highlights the importance of proactive water management. By planning ahead and adopting efficient practices, organic growers can strengthen resilience and align with California’s long-term sustainability goals.
