As model for long-term water sustainability and benefits, rice growers are looking to test rotational rice fallowing approaches. The opportunity to create water credits is proving to be a key additional driver.
Rotational rice fallowing is an innovative regenerative agriculture practice that involves temporarily resting fields by leaving them uncultivated for specific periods. This strategy not only conserves water but also actively rebuilds soil health, enhances biodiversity, and strengthens ecosystem resilience. It exemplifies key regenerative agriculture principles by working with nature rather than against it, particularly valuable in regions facing water scarcity or where balancing agricultural and ecological water needs is critical. Verified Water provides financial incentives to farmers, promoting rotational fallowing programs that enable a more sustainable and regenerative approach to water use, agricultural productivity, and environmental stewardship.
Rotational rice fallowing plays a critical role in advancing regenerative agriculture practices. By reducing synthetic inputs like fertilizers and pesticides during fallow periods while promoting natural soil building processes, it helps lower production costs, improves ecosystem health, and eases regulatory pressures. This regenerative approach is increasingly vital for the long-term viability of rice farming. Through fallowing, the industry can better protect itself from escalating costs and environmental regulations while building more resilient agricultural systems.
How Regenerative Rotational Rice Fallowing Works
Farmers voluntarily participate in rotational rice fallowing programs, temporarily ceasing cultivation on designated portions of their land while implementing regenerative practices. The Verified Water program offers incentives to offset the transition period, ensuring farmers are financially supported while contributing to water conservation and ecosystem restoration goals. Key elements include:
1. Water Conservation: By not irrigating fallowed fields, large volumes of water are saved, creating water credits under the Verified Water program while supporting natural water cycle restoration.
2. Soil Regeneration: The fallow period allows for natural soil building processes, increased organic matter accumulation, and enhanced soil microbial activity.
3. Ecosystem Enhancement: Cover cropping during fallow periods supports beneficial insects, soil microorganisms, and wildlife, creating a more diverse and resilient agricultural ecosystem.
4. Monitoring and Compliance: Strict oversight ensures that the fallowed land remains managed according to regenerative principles, maximizing both water savings and ecosystem benefits.
A Real-Life Example in Regenerative Agriculture
The Davis Ranches Rotational Rice Project in California's Sacramento River watershed demonstrates how regenerative rice farming practices can enhance both water conservation and agricultural sustainability. The project involves 15 acres of rice fields and 45 acre-feet of water, generating approximately 14,600 Verified Water Credits. Sale of Verified Water Credits helps Davis Ranches transition to regenerative practices while offsetting reduced crop production income.
Regenerative and Environmental Benefits:
• Building Soil Health: The inclusion of vetch as a cover crop demonstrates regenerative principles by naturally enriching soil, improving structure, and enhancing water retention capacity. This reduces the need for artificial inputs while promoting long-term soil vitality.
• Enhancing Biodiversity: Rotational fallowing with cover crops creates diverse habitats supporting beneficial insects, birds, and soil microorganisms, strengthening the entire agricultural ecosystem.
• Water Cycle Restoration: The project dedicates water rights to maintain in-stream flows, supporting natural water cycles and aquatic ecosystems in the Sacramento River.
• Natural Pest Management: By incorporating vetch cover crops, the project reduces reliance on pesticides, supporting beneficial insect populations and natural pest control mechanisms.
• Ecosystem Protection: Unlike conventional fallowing, regenerative rotational fallowing prevents soil erosion and dust generation while creating vital habitat for shorebirds and terrestrial species.
• Climate Resilience: Reduced equipment use lowers carbon emissions, while improved soil health increases carbon sequestration capacity, contributing to climate change mitigation.
The Davis Ranches Rotational Rice Project and Verified Water exemplify how regenerative agriculture can transform conventional farming practices, creating systems that benefit soil health, water resources, biodiversity, and farming communities alike.
