How innovation systems emerge to solve ecological problems: Biofuels in the United States and Brazil

This paper discusses the re-emergence of biofuel innovation systems in the United States and Brazil. We argue that innovation systems emerge and evolve to solve a problem, and that the way the problem is framed and articulated has a significant impact on the direction and momentum of this evolution. Additionally, innovation sequences occur with a recurrent pattern of changing problems and innovative solutions. We consider the role of the State as a core actor in the mobilisation of innovation systems and discuss how specific institutional arrangements, political contexts and technological competencies influence how problems are framed. We find that role of the State varies across time as well as across different geographical regions. Finally, we suggest that as ecological problems intensify we might expect to see an increase in State intervention in innovation systems
