In this book, the core problem concerns the interactions between changes in innovation models, the institutional condition of production system greening and the social consequences. Six innovation processes are, analyzed in the agricultures of Burkina Faso, Cameroon, Haiti, Madagascar and Senegal, respectively. Chapter 7 analyzes the extent to which the lack of full agricultural policy explains the failure of technology transfer based on capital intensification. These situations converge to demonstrate that collaborative innovation models are particularly useful for development, as they adapt the studied processes to local needs. These models imply more commitment from public policy innovation in the agricultural sector, mainly food, in order to regulate the market and encourage funding of infrastructure and investment in production.
