Is your farm climate ready cfsa 2012 presentation

  1. 1. Is Your Farm Climate Ready? Best Practices for Managing Climate Risk on Your Farm“Although agriculture has a long history of successful adaptation to climate conditions, the current pace of climate change and the intensity of projected climate changes represent a novel andunprecedented challenge to the sustainability of U.S. agriculture.“ Climate Change and Agriculture: Effects and Adaptation. C. Walthall, J. Hatfield, L. Lengnick, E. Marshall and P. Backlund. 2012. USDA Technical Bulletin 1935
  2. 2. Agricultural Risk
  3. 3. Climate Risk Degree to which a Ability of a farm tofarm experiences climate- cope with climate- related events. related events. Exposure Adaptive Capacity Farm Vulnerability
  4. 4. How Vulnerable Is Your Farm? HIGH HIGH MOD High HIGH MOD LOW EXPOSURE MOD LOW LOW Low Low ADAPTIVE CAPACITY High
  5. 5. Assessing Your Vulnerability• What are your key exposures? – Increasing CO2 and average temperatures – Increasing weather variability – More extreme events – Impact synergies• What is your farm’s adaptive capacity? – Production system sensitivity – Resource characteristics – Recovery reserves
  6. 6. Your Farm Exposure?• Key near term impacts in Southeast – More variable temperatures and precipitation – More extreme weather events – Warmer nights – Higher pest pressure and novel pests• Useful regional projections now available• No local projections, but landscape moderates regional effects
  7. 7. Assessing Adaptive Capacity• Soil• Water• Microclimates• Infrastructure• Crops/Livestock• Production system• Extreme events plan• Farm reserves• Community support
  8. 8. Enhancing Adaptive Capacity:Three Management Strategies
  9. 9. Resistance Practices Strategy: Accept increased costs and more risk to maintain existing production system.• Water • Temperature – Select robust types – Select robust types – Equipment needed for – Adjust field operations flexible timing of field – Physical protection and operations space conditioning – Irrigation and drainage• Pests and Disease • Manage Climate Risk – – Increase reserves Select robust types – IPM – Production insurance – Physical protection – Use seasonal – Increased pesticides forecasting in planning
  10. 10. Know Crops and Livestock• Optimum moisture and temp. ranges?• Critical periods and thresholds?• Tolerance for variability and extremes? Vegetable Crop Irrigation NC Coop. Extension
  11. 11. Robust Types? Red Orach (Atriplex hortensis) Sahiwal http://www.thecattlesite.com/breeds/dairy/96/sahiwa l/overview
  12. 12. Micro-irrigation• Low-flow Drip emitters technology• Water delivered directly to plant roots• Delivers just Micro-sprayer enough water for plant use• Prevents leaching Bubbler and runoff losses
  13. 13. Integrated Pest Managementhttp://attra.ncat.org/attra-pub/PDF/ipm.pdf
  14. 14. Resilience PracticesStrategy: Design responsive farm ecosystem to reduce risk.• Build soil health• Manage water cycle• Enhance biodiversity• Integrate robust crops and livestock• Manage “farmscape” – Edges – Topography/microclimates – Restore wetlands – Agroforestry in riparian areas• Use adaptive management• Regularly assess farm vulnerability• Use climate projections in strategic planning
  15. 15. Healthy Soils Capture and Store WaterFrom Sustainable Soil Mgt. ATTRA
  16. 16. Manage Water Cycle• aim: maximize water infiltration and storage in soil• strategy: maintain high soil OM/protect soil surface• practices: crop rotation, cover crops, mulches, contour plowing, terracing, reduced tillage• benefits: reduces need for irrigation, improves water quality leaving farm, increases groundwater recharge http://www.css.cornell.edu/faculty/hmv1/watrshed/ntcover.JPG

  20. 20. Transformation Practices Strategy: Design self-organizing ecosystem capable of sustained food and fiber production using renewable resources in a variable climate.• On farm – Climate-ready crop and livestock species, enterprises, production practices – Regional markets – Focus on renewables and soft adaptations – Convert cropland to pasture and forest• Food system – Supply seasonal diet – Regional production and processing
  21. 21. Key Actions Now• Recognize you are farming on a new planet• Address key farm vulnerabilities• Manage for resilience with “no-regrets” adaptations• Consider climate change in longer-term decisions• Near term challenge is water
