The Partnerships for Agricultural Climate Action Act establishes a new grant program within the Department of Agriculture, administered by the Secretary. This program is designed to provide financial assistance to various covered entities , including state departments of agriculture, Tribal Governments, producer associations, and institutions of higher education. The grants will fund efforts to develop, modify, or implement eligible proposals focused on climate adaptation and climate mitigation within agricultural management systems. Eligible proposals must align with USDA climate action plans, Natural Resources Conservation Service practices, and current scientific research, including traditional ecological knowledge. These proposals must aim to achieve at least two outcomes: increased carbon sequestration, reduced greenhouse gas emissions, or enhanced resilience against extreme weather. Priority is given to proposals benefiting historically underserved producers , those transitioning whole farm systems to ecologically sound practices, and those incorporating additional conservation goals like soil health and water quality. The bill allocates $150 million annually from fiscal years 2026 through 2034, with specific percentages reserved for development, implementation, and grants to Tribal Governments, which also receive a higher federal cost-share.
