Brazilian Production Evolution of Production: sugarcane, sugar and ethanol
4
Learning Curve – Brazilian Ethanol
5
Brazilian Ethanol: reasons for success Brazil established a dynamic relation between Research and Production since the 30’ies Sugarcane, an excellent energy crop Creation of the “Brazilian Model” combining efficient sugar and ethanol production

Questions: What are the limits for traditional sugarcane breeding ? What is sugarcane productivity potential? Is sugarcane productivity close to its potential? Natural selection really optimizes or there is a way to make it better? Is “energy cane” possible? What is the current status of photosynthesis in the world today? What are the most important bottlenecks?
