The USDA has published a new comprehensive resource book on practices that agricultural producers can use to adapt to variability and trends in climate. While the material is aimed at the Midwest and Northeast, there is a lot of information here that would also be useful to Southeastern farmers and extension agents.
I especially like the Adaptation Workshop and the four examples they use to explain how to use it. Take a look and see what is useful for you. You can get the complete 72-page document in PDF at http://www.climatehubs.oce.usda.gov/sites/default/files/adaptation_resources_workbook_ne_mw.pdf.
