Distribution of grain cropping in Australia
7
S C I E N C E F O R D E C I S I O N M A K E R S Outline Operational uses Rainfall reliability wizard: grain adaptation Integrated toolset: productivity Growest: pasture forecasts National Monitoring system: drought policy Conclusions/Future extensions
8
S C I E N C E F O R D E C I S I O N M A K E R S Operational Uses Agricultural adaptation –Crop, livestock decisions Climate risks –Fire risk, storm warning, frost warning Agricultural risks –Pest & disease outbreaks, weed incursions, plague locust Policy delivery –Natural resource management, conservation, rural policy, drought relief, quarantine

S C I E N C E F O R D E C I S I O N M A K E R S Conclusions Also consider flexible, pragmatic systems that: Analyse data rapidly Provide simple outputs Respond to wide range of requests Use our skills to provide advice on output Future Weather Wizard (frost, growing degree days, vernalisation) Climate change/adaptation
