Climate Suitability Maps for Walnut Production Under Future Climate Scenarios

Eight global climate models and historical observations provide climate suitability maps for walnut production. The Department of Primary Industries and Regional Development (DPIRD) produced this assessment using multicriteria analysis models for the Horticulture and Viticulture node. Maps are provided for overall suitability, individual phenophases, and phenophase-climate variable combinations.

Use Cases

• Modeling future crop suitability based on projected climate variables
• Assessing climate risk for specific growth stages (phenophases) of walnut trees
• Comparing climate change impacts across different global climate model (GCM) ensembles
• Informing agricultural adaptation strategies using spatially explicit suitability maps

Strengths

• Uses eight distinct global climate models (GCMs) for ensemble analysis
• Provides maps for individual phenophases and variable combinations, offering detailed breakdowns
• Includes a derived ensemble median map for consolidated analysis
• Based on a published, transparent multicriteria analysis (MCA) framework

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to data_gov_au
