The agro-food chain is subjected, in its whole route, to a high business concentration. Starting with the first stretch, seeds, we can observe that ten of the biggest companies (such as Monsanto, Dupont, Syngenta, Bayer…), according to data from the ETC Group, control one half of sales. Copyright laws, which give exclusive rights on seeds to these companies, have further stimulated the business concentration of the sector and have eroded the peasant right to the maintenance of indigenous seeds and biodiversity.
