Agriculture both affects and is affected by climate change. The resources below explore implications of climate change on the environment, agricultural productivity, and food security.
Climate Change and Agriculture in the United States: Effects and Adaptation
USDA. ARS. Climate Change Program Office.
This 2013 report finds that "projections for crops and livestock production systems reveal that climate change effects over the next 25 years will be mixed. The continued degree of change in the climate by midcentury and beyond is expected to have overall detrimental effects on most crops and livestock."
Effects of Climatic Variability and Change on Forest Ecosystems: A Comprehensive Science Synthesis for the U.S. Forest Service
USDA. Forest Service.
This 2012 report finds that [climate change] "disturbances are likely to change the structure and function of ecosystems across millions of acres over a short period of time with detrimental effects on forest resources."
USDA. Natural Resources Conservation Service.
Discusses weather, climate, climate variability, climate change, the greenhouse effect, and climate change impacts on agricultural production.
AgEcon: Search for Climate Change or Global Warming
University of Minnesota. Waite Library. Dept. of Applied Economics.
Search a full-text database of agricultural economics working papers, conference papers, and journal articles for items on climate change or global warming, by inputting "climate change" OR "global warming" in the search boxes.
USDA. Economic Research Service.
Presents an overview and background; looks at how agriculture can mitigate climate change; considers how changed yield potentials will alter varietal selection, cropping patterns, grazing locations, and input use.
U.S. Environmental Protection Agency.
Overviews of climate change indicators, greenhouse gas emissions, health and environmental effects, economics, policy issues. See also their page Agriculture and Food Supply.
International Food Policy Research Institute.
Links to IFPRI publications, datasets and knowledge products about climate change and agricultural growth, food security, natural resources and sustainability.
The World Bank.
Presents information on the effect of climate change on developing nations. These countries are expected to be most affected by climate change's impact on agriculture, food and water supply.
Crop Science Society of America.
Points to the Society's presentations and documents, such as the August 2010 report "Agriculture's Role in Greenhouse Gas Emissions & Capture."
Climate Change Program Office
USDA. Office of the Chief Economist.
Office coordinates USDA's agriculture, rural and forestry-related climate change program and policies. Links to key reports and fact sheets.
Environment & Agriculture: Climate: Implications for Agriculture
Johns Hopkins Center for a Livable Future.
Synthesis and Assessment Product 4.3 (SAP 4.3): The Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States
U.S. Climate Change Science Program.
Reviews literature, measurements and data collected by U.S. government agencies. Finds that climate change is already affecting U.S. water resources, agriculture, land resources, and biodiversity, and will continue to do so.
