Conclusions
• Mapped agriculture areas for Asia and Africa
• Conducted intensive ground data for priority
countries
• Tested methods at country level
• Support to multidisciplinary teams
Next steps
1. Map cropland areas for Africa
2. Develop automated techniques using open
source software
3. Dissemination of geospatial outputs across
institute
4. Conducting capacity building courses at institute
wide
5. Collaborations with other CG centres and other
research organizations
