Do you want to download the data from GYGA? Please read the license information here.

Are you working in a private company and you want to use the data from GYGA? Please read the Licensing and sponsorship page.


The GYGA platform contains the following data:
  1. Actual and potential yield and yield gap
  2. Actual and potential water productivity
  3. Actual and minimum nutrient requirement
  4. Underlying data on weather, soil and cropping systems
  5. Climate zonation and Technology Extrapolation Domains (TEDs).
The data are available at three different geographical levels:
  1. National level
  2. Climate zone level
  3. Reference weather station level (location).
Can I get a sample of the data? Sample datasets can be downloaded in Excel format. For example:
  1. Country-level data (all crops grown in one country), e.g. for the Netherlands download the file here with country results and another file here with country model run results
  2. Country-level data organised by region (one crop grown on one region), e.g. for Europe download a file here.
Where can I download the GYGA data?
  1. From continent pages. Find a table with the regions below
  2. From the country pages. Find a table with the various countries further below
  3. From the Atlas viewer.


The tables below give an overview of the current coverage of GYGA. Do you have a specific request, e.g. to have a particular crop or country added or updated? Please contact us!
