Global Futures & Strategic Foresight
1. Improved tools
2. Stronger community of practice
3. Exploring alternative futures
4. Informing decisions
1. Improved modeling tools
• Climate models
• Water models
• Crop models
• IMPACT economic model
2. Stronger community of practice
• All 15 CGIAR centers now participate in GFSF– AfricaRice, Bioversity, CIAT, CIFOR,
CIMMYT, CIP, ICARDA, ICRAF, ICRISAT, IFPRI, IITA, ILRI, IRRI, IWMI, WorldFish
• Collaboration with other global economic modeling groups through AgMIP– PIK, GTAP, Wageningen, IIASA, UFL,
FAO, OECD, EC/JRC, USDA/ERS, …
• Role of agricultural technologies
• Regional studies
• Analyses by CGIAR centers
• AgMIP global economic assessments
• Private sector

Irrigated Wheat (S. Asia)
Rainfed Rice (S. + SE. Asia)
Rainfed Potato (Asia)
Rainfed Sorghum (Africa + India)
Rainfed Groundnut (Africa + SE Asia)
Rainfed Cassava (E. + S. + SE. Asia)

4. Informing decisions
• CGIAR
• National partners
• Regional organizations
• International organizations and donors
Concluding thoughts
• Not one future but many possible futures
• Which of the many is realized depends on our choices
• Understanding those choices requires many tools and approaches
• We look forward to engaging with other GCARD partners
