- Crop irrigation water demand - grid (Water requirements for crop irrigation, calculated as daily moisture deficit during the growing season., type: model (from/to model))
- Degraded forest area (Permanently deforested areas for reasons other than expansion of agricultural land (calibrated to FAO deforestation statistics)., type: model (from/to model))
