Extreme climatic events  are projected to adversely impact productivity for livestock systems . This includes reduced pasture growth rates between 3-23% by 2070 from late spring to autumn and elevated growth in winter and early spring . Heavy rainfall and storms are projected to lead to increased erosion, particularly in extensively grazed systems on steeper land, reducing productivity for decades, reducing soil carbon  and increasing sedimentation. Increased heat stress in livestock is projected to decrease milk production and livestock reproduction rates  . In Australia, the average number of moderate to severe heat stress days for livestock is projected to increase 12-15 d by 2025 and 31-42 d by 2050 compared to 1970- 2000 . In New Zealand, an extra 5  to 7  moderate heat stress days per year are projected for 2046- 2060  , which would especially affect animals transported long distances  and strain the cold chains needed to deliver meat and dairy products safely. The distribution of existing and new pests and diseases are projected to
