USDA Contributes to the Fifth National Climate Assessment, Highlighting Impacts on Agriculture, Forests and Rural Communities and Adaptation Needs

WASHINGTON, Nov. 14, 2023 - The U.S. Department of Agriculture (USDA) announced today its important contributions to the Fifth U.S. National Climate Assessment (NCA5) demonstrating a commitment to understanding and addressing the effects of climate change.

“Our farmers, ranchers, and forest landowners are on the front lines of climate change. USDA’s role in the NCA5 exemplifies our commitment to supporting these individuals and communities, especially those who are disproportionately affected,” said Agriculture Secretary Tom Vilsack.

The NCA5 is a congressionally mandated report that analyzes the effects of climate change on sectors and regions across the U.S. economy. The report, released on November 14, 2023 by the U.S. Global Change Research Program, was developed through a partnership with 14 federal agencies and included 58 USDA scientists. The information and analysis in the report can be used to inform decision-making, but it does not prescribe specific policies or actions.

USDA’s contributions to the NCA5 highlight the effects of climate change on agriculture, forests, food systems, historically underserved communities, and natural resources. The NCA5 emphasizes the increasingly important role of adaptation in building resilience, and the role of the land sector in mitigating greenhouse gases. It demonstrates how climate change affects the livelihoods of USDA’s stakeholders and it provides examples of how land managers are changing their operations and practices in response to changing climate conditions.

The effects of climate change are not confined to specific regions; rather, the entire nation is vulnerable to its consequences. Climate-induced changes in productivity, trade infrastructure, and livelihoods affect everyone – U.S. consumers who depend on globally integrated food and forest-product supply chains, international consumers of U.S. products, and U.S. producers whose livelihoods are connected to global food and forest-product supply chains.

USDA recognizes that agriculture and forests have pivotal roles to play in addressing climate change. The NCA5 is a comprehensive and timely evaluation of climate change’s relationships with the land sector. By understanding climate change and prioritizing innovation, land managers can be more adaptable to changing conditions and working lands can help to lessen the impacts of climate change.
