'Motta’s book offers a comparatively nuanced analysis of the construction of ‘bio-hegemony’ in Argentina and Brazil, as GM crops are instituted. These case studies establish the fundamental importance of countermovement alliances as democratic registers, especially in politicizing hegemonic claims of the superiority of transgenic technology, and they offer a rich primer on the ecology of social and political contention.' Philip McMichael, Cornell University, USA and author of Food Regimes and Agrarian Questions (2013)'Biotechnology does not rule by itself. As this book shows, social and political struggles and confrontations at the local, national, and global level are involved in the introduction and expansion of genetically modified crops in Brazil and Argentina. The dense and rich analysis of social movements and actors presented will become a model for the analysis of movements that challenge global capitalist developments.'Elizabeth Jelin, Senior Researcher CIS CONICET-IDES, Buenos Aires.
