3. About the study 142 countries 35 crops Interdisciplinary No scenario-study (only base-line scenario) The study presents FAO’s estimates of what will happen in the future. They are not the result of a particular scenario nor do they represent a particularly ‘desirable’ future

4. Driving forces

5. Sources of growth in developing countries (2005/07 – 2050)

6. Sources of growth in production

7. Yield gaps (wheat)

8. Harvested area increases 2005/07 – 2050

12. Changes in irrigated land and accompanying water withdrawals
