Global Wheat, Sugarcane, and Maize Yield Grids 2000-2014

Environmental Information Data Centre provides global spatial data on yields of wheat, sugarcane, and maize at 0.25 and 0.5 degrees resolution. Annual yield data from 2000 to 2014 were extracted from agricultural statistics and spatially disaggregated to produce gridded maps per crop type.

Use Cases

• Constraining agro-ecosystem carbon cycling estimates for atmospheric CO2 inversion studies using annual wheat, sugarcane, and maize yield grids.
• Providing yield inputs for agro-ecosystem biogeochemistry models at 0.25 and 0.5 degrees spatial resolution.
• Analyzing spatial and temporal yield trends for wheat, sugarcane, and maize across a 15-year global time series.
• Spatially disaggregating national and regional agricultural statistics to gridded crop yield maps using EarthStat crop distribution data.

Strengths

• Covers a 15-year time series from 2000 to 2014.
• Provides data at two spatial resolutions: 0.25 and 0.5 degrees.
• Includes three major global crops: wheat, sugarcane, and maize.

Limitations

• Data is temporally stale, ending in 2014.
• Relies on statistical disaggregation which may introduce spatial estimation errors.
• Limited to three crop types, excluding other major agricultural commodities.
