Assessment of impacts of climate change on US agriculture accessible to students, researchers, and policymakers.

This volume reports the results of a rigorous and quantitative assessment of the impacts of climate change on US agriculture. It advances work on climate impacts by using scenarios from state-of-the-art climate models. It describes the forces likely to shape US agriculture over the next century, including policy and economic issues, and their interaction with climate change. It offers directions for future research and implications of climate change for agricultural policy. The basic findings are that climate change is positive for agriculture production although southern parts of the US could be harmed. Negative consequences of climate change include effects on pesticide use, run-off of nutrients into coastal areas, and potential regional conflicts for some groundwater sources. This authoritative assessment will be accessible to a broad readership of students, researchers, and policymakers.
