Wheat Stem Rust Climate Suitability Maps for Australia

Maps of modelled climate suitability for wheat stem rust, a biosecurity risk, are provided in GeoTIFF format. The data includes outputs from eight global climate models, historical observations, and ensemble medians for monthly, phenophase, and variable-specific suitability. The Department of Primary Industries and Regional Development produced this assessment using a multicriteria analysis framework.

Use Cases

• Train a geospatial model to predict wheat stem rust suitability using monthly climate suitability GeoTIFFs from eight GCMs.
• Compare ensemble median climate suitability maps against historical observation maps to assess climate change impact.
• Analyze phenophase-specific climate suitability maps to identify critical growth stages vulnerable to wheat stem rust.
• Integrate phenophase/climate variable combination maps into agricultural risk models for targeted biosecurity planning.

Strengths

• Data includes outputs from eight distinct global climate models, providing a range of projections.
• Maps are provided for multiple analytical layers: monthly, phenophase, and variable-specific climate suitability.
• The assessment is based on a documented multicriteria analysis framework developed for consistent vulnerability assessment.

Limitations

• The dataset lacks explicit row or column counts, making its tabular structure and volume unclear.
• Data is specific to wheat stem rust and Australia, limiting direct applicability to other pests or geographies.
• Reliance on model outputs introduces uncertainties inherent to the chosen GCMs and the multicriteria analysis assumptions.
