Climate change poses environmental, social, and agricultural challenges that require adaptation measures or means to help human and natural systems to adjust to new or changing climatic patterns.
Changing precipitation, changing temperature patterns and increasing atmospheric greenhouse gases can significantly impact forest and agro-ecosystems at national, regional, and local scales-- changes in precipitation patterns relative to historic trends across the US will result in greater climate variability and more intense fluctuations in extreme climate events.
Impacts of climate change are expected to vary geographically and temporally. For example, in the western U.S., the form, amount and timing of precipitation is changing. All these factors point to a changing climate which can present threats to agricultural production systems as well as opportunities to improve and expand production. Adjustments to production system inputs, tillage, crop species, crop rotations, and harvest strategies, as well as altered use and assessment of natural resources are anticipated adaptations to climate change in agricultural production. New research to increase the resilience of agronomic systems to climate change and to enable exploitation of opportunities that may arise is anticipated.
USDA Climate Change Adaptation Plan
"Climate change has the potential to disrupt USDA’s efforts to meet the core obligations and responsibilities articulated by its mission, and goals. The vulnerability of USDA operations and programs to climate change will be highly dependent on the magnitude and pattern of climate changes, as well as on changes in climate extremes.
Changing precipitation and temperature patterns as well as increasing atmospheric greenhouse gas concentrations affects forest and agro-ecosystems at national, regional, and local scales. These changes may have significant implications for USDA program participation and costs" (USDA CCPO, 2012).
To address the future challenges of the changing climate, USDA released a draft of its climate change adaptation plan.
