gaia 2.0.1

gaia is a powerful and user-friendly tool designed to estimate crop yield responses to climate impacts, enabling robust projections and streamlined workflows. Explore its full capabilities in the User Guide.

Key Features of gaia:

General Features:

  • Empirical Econometric Modeling: Estimate annual crop yield responses to climate impacts using an empirically grounded approach.
  • Streamlined Workflow: Simplify your analysis with a single wrapper function, yield_impact, for running models efficiently.
  • Integrated Climate Data Processing: Process widely-used ISIMIP-style climate NetCDF files without the need for external tools.
  • Data-Driven Insights: Leverage historical weather, CO2, and crop yield data for robust model fitting.
  • Future Projections: Project annual yield shocks for 17 crops using CMIP/ISIMIP bias-adjusted precipitation and temperature datasets. gaia supports both daily and monthly climate data formats.
  • Flexible Crop Coverage: Estimate yield shocks for 17 major crops, with the option to add more crops by providing appropriate input data.
  • Model Supports: Designed to support Global Change Analysis Model (GCAM) as well as other non-GCAM modeling frameworks.

GCAM-Specific Features:

  • Ready-to-Use Outputs: Generate XML files for agricultural productivity changes at region-basin intersections, compatible with GCAM.
  • Version Compatibility: Supports GCAM v6.x and v7.x.
  • Flexible Time Steps: Offer options for both 5-year and annual time steps for GCAM.
  • Scenario Flexibility: Choose from various Shared Socioeconomic Pathways (SSPs) in combination with climate scenarios (e.g., RCPs).
