Climate Bond Funding for Climate Smart Agriculture
Office of Agricultural Resilience and Sustainability
Background on Proposition 4 Funding
In November 2024, California voters approved Proposition 4, a $10 billion Climate Bond designed to safeguard communities and natural resources from climate change.
- $40 million for State Water Efficiency and Enhancement Program (SWEEP)
- $65 million for practices that improve soil health or accelerate carbon removal or sequestration
- $15 million for a new equipment sharing program.
The Office of Agricultural Resilience and Sustainability (OARS) will implement these programs. In early 2026, OARS plans to release a solicitation for the Healthy Soils Program (HSP) and SWEEP Block Grants, as well as begin outreach for the Equipment Sharing Program.
The Bond requires CDFA to solicit public feedback on each program’s solicitation guidelines. This webpage is the hub for CDFA’s Climate Bond resources and outreach. We also recommend that you sign up for our mailing list to receive the latest updates. We look forward to your partnership in shaping these programs.
Public Comment Period
The public comment period for the HSP and SWEEP Block Grant Draft Application Guidelines is open from DATE to DATE, 2025.
Additionally, OARS will present the draft guidelines to the Environmental Farming Act Science Advisory Panel (EFASAP) on February 12th.
The public will have an opportunity to provide oral public comment during the meeting.
State Water Efficiency and Enhancement Program (SWEEP)
The State Water Efficiency and Enhancement Program (SWEEP) helps California farmers conserve water and reduce greenhouse gas emissions through climate-smart irrigation upgrades. By funding technologies like efficient irrigation systems, pump improvements, and soil moisture monitoring, SWEEP supports growers in becoming more resilient to drought while lowering energy use and operational costs. The program also works through regional Block Grant Recipients who provide hands-on technical assistance and bring resources directly to local communities.

Healthy Soils Program (HSP)
Since 2018, the Healthy Soils Program has helped farmers and ranchers adopt sustainable practices that build soil organic carbon and reduce land-based greenhouse gas emissions. By improving soil structure, water retention, biodiversity, and habitat, these projects strengthen the resilience of California’s farms and ecosystems. The program also invests in research and local outreach to expand the impact of soil-health practices across the state.

Equipment Sharing Program
Prop 4 includes $15 million for the establishment of the Regional Farm Equipment Sharing Program, designed to facilitate equipment sharing among small farmers and ranchers.
