Presentation Transcript

  1. Adapting to Increasing Variability Climate Change and Agriculture

  2. Longer season cultivars Supply irrigation water Drain soil to reduce water logging Larger planting equipment Modify housing for animals Provide alternative water sources for animals Perennial crops-modify pruning, fruit load Specialty crops- modify environment to protect against extremes (temperature, wind) Agricultural Adaptation

  3. US Corn Production

  4. South Dakota Crop Distribution

  5. Improved Agronomic Systems

  6. Soil Erosion

  7. Spring Precipitation (Ames)

  8. Increased Subsurface Drainage

  9. 2010 through Sept 27 Years having more than 8 days 7 350% Increase 2 3.7 5.2 41% Increase

  10. Conservation Tillage

  11. Iowa County Yields

  12. Soybean Yield Deviations

  13. Variation in Yields The majority of the yield losses due to the weather are short-term stresses

  14. Irrigation

  15. Water Requirements Water Deficit need 120 mm more water to grow 300 bu corn

  16. Role of proper soil management has been overlooked as a reservoir of water to meet plant needs Adaptive strategies will have to ensure that soil is a foundational piece of the process Adaptation Strategies

  17. Temperature Response in Animals

  18. Changes in crop rotations Changes in water management (irrigation and drainage) Changes in fertilizer management Changes in crop management Changes in animal management Ultimately we are going to have to quantify G x E x M interactions to develop effective adaptive strategies Practices

  19. Agriculture has adapted to climate change and will continue to adapt Practices will have to cope with larger extremes in temperature and precipitation Agricultural Adaptation
