The mergers of multinational chemical-pharmaceutical have deeply reshaped the global seed industry, reducing the number of leading firms integrating firms with complementary activities and product offering. The increased role played by multinational has happened along with the rapid increase of the market control determined from the market sales of Genetically Modified Organisms (GMO) seeds. The seed market concentration has raised concerns among public authorities and policymakers, farmers, and the wider public opinion, all alarmed by negative consequences on prices, biodiversity, product choice, and food security. The aim of this paper is to investigate the current wave of concentration identifying the several implications derived and the role that public policies can play. The paper ends up putting evidence of a possible alternative strategy for the improvement of the seed market conditions. The methodology adopted is that of the traditional revision based on specific eligibility criteria identified considering the characteristics of the research aims.
