This book deals with different experiences launched in many developing countries in these sectors and shows how local initiatives can provide answers to the pessimism of experts and the media. Multidisciplinary analysis and practices explain how collective work creates value chains that can foster local and national economic development. The authors revisit the innovation agri-food models that contribute to economic development.
Agri-Innovations and Development Challenges is composed of general presentations of innovations applied in developing countries, as well as specific studies on the joint valorization of knowledge and experience in agri-food engineering
