  11. Yield/ETc (NP Almonds)

  12. Yield/Applied Water (Citrus)

  13. Yield/ETc (Citrus)

  14. Crop Resilience Strategies • Canopy reduction • Reduce crop water demand • Reduce stress • Partial cover irrigation • Reduce evaporative losses • Some issues with recovery • “Sunscreen” products • Reduce stress • Limited success

  15. Business Resilience Individual businesses

  16. Almonds • High water requirements • Cost of production increasing • Returns high • Cost of replacement water generally justified • Few plantings removed

  17. Citrus • Moderate water requirements • Cost of production increasing • Returns variable (varieties, markets) • Cost of replacement water often justified • Some plantings removed

  18. Wine Grapes • Low water requirements • Cost of production increasing • Returns low (often below cost of production) • Cost of replacement water not justified • Many plantings removed

  19. Business Resilience regional economy

  20. Drought vs. Murray-Darling Basin Plan Drought

  21. Drought vs. Murray-Darling Basin Plan Drought Basin Plan

  22. Conclusions • Resilience measured at different scales • Survival of permanent plantings is paramount • Management techniques are available to maintained production • Business survival is about more than just crop response to water deficit • Regional economies generally coped with short term drought, but.......?
