75 % des variétés de semences ont disparu en un siècle. Or elles sont la base même de la vie. Comment expliquer, alors, que ce sujet crucial ait été si longtemps maintenu hors de portée et de compréhension du grand public ? La réglementation, il est vrai, est particulièrement complexe. Mais surtout, celui qui possède la semence contrôle toute la chaîne alimentaire. Détenir ce marché mondial représente des enjeux financiers colossaux. Cette appropriation du bien commun a commencé à se mettre en place, il y a plus de cinquante ans, avec les semences industrielles. Aujourd'hui, elle s'accentue avec les OGM et les « nouveaux OGM », privant des paysans du monde entier du droit élémentaire de cultiver leurs propres graines. Comment et pourquoi ce bien si précieux, qui devrait appartenir à tous, a-t-il été privatisé ? Quelles sont les conséquences avérées d'une telle logique ? Quels risques fait-elle courir à la nature, dont l'être humain est lui-même une composante ? Telles sont les questions, vitales pour notre avenir, abordées dans ce carnet.

This book is the result of a study on demand-led plant variety design for changing markets in Africa, the purpose of which is to identify and share best practices in demand-led plant breeding from private and public sector breeding programmes worldwide. The intended audiences are professionals in plant breeding and related areas, such as seed production, who have interests in developing and disseminating new plant varieties as a way to increase productivity and profitability in crop agriculture, especially in Africa. The volume is also intended for use as a resource book for the education of postgraduate scholars in plant breeding and genetics, and for the continuing professional development of plant breeders. For this purpose, boxes are included in the main sections of each chapter that summarize its educational objectives and present the key messages and questions that are involved; in addition, there is a final box at the end of each chapter that summarizes its overall learning objectives.
