The GROW-Africa (Groundtruthing Remote-sensing for Optimizing Yield in Africa) database includes observations of crop yields across Africa for the period 1960-2023. The data set, selected from GROW-Africa, includes the point-based yield estimates (based on farmer surveys or crop cuts) from non-LSMS (World Bank Living Standards Measurement Study) sources.
Provider's website
[1] GROW-Africa (Groundtruthing Remote-sensing for Optimizing Yield in Africa) Database, v2.0. The file 'GROW-Africa_Point.xlsx' was selected.
Documentation
[2] Geyman, E.C., Ferris, A., Sahajpal, R., Anderson, W., Lee, D., and Hausmann, N. An Africa-wide agricultural production database to support policy and satellite-based measurement systems. Scientific Data (in review). 2025.
Pre-processing
Original data of file 'GROW-Africa_Point.xlsx' was processed and filtered:
- location (latitude and longitude) must be known
- plant and harvest date must be available
- planting and harvest date must have at least 90 days in between
The unique name is based on attributes site_name, longitude and latitude.
The comment indicates the rowid of the dataset file.
The geometry accuracy is taken from the attribute SPATIALPRECISION_KM.
CROP_CODE
Attribute: Crop
Remark: selected annual arable crops
CROP_DEV_BBCH
Attribute: PlantDate and HarvestDate
Remark: -
SO_FWT_KGHA
Attribute: Yield_ton_ha_
Remark: the fresh weight was converted from ton per ha to kg per ha
Management
There was no further information on the crop management.
