Grazing systems management into 2030 locations
Aims

To report on the combined use of sophisticated biophysical models such as Grass Gro with localised rainfall, temperature and carbon dioxide levels predicted from various climate models out to 2030. 

Key messages

The main impacts of climate change by 2030 on grazing livestock enterprises is likely to be shorter  growing seasons, greater variability in pasture growth, reduced pasture quality, less available pasture, reduced wool quality and increased variability in farm gross margins. Possible adaptations to alleviate
some of these impacts are;

  • Minimising the need for supplementary feed by reviewing lambing and calving times, age at first joining, stocking rates and sale times,
  • Increase flexibility in systems by varying sale times/rules, confinement feeding, movement, more animal trading (core breeding), agistment, matching feed demand to pasture production, and
  • Improved pasture utilisation by grazing management.
