A fierce controversy over genetically modified (GM) crops has been raging in India for over two decades. Analyzing India’s regulatory regime for GM crops, this article focuses on the modes through which state bureaucracies know the environment. It argues that two epistemologies - scientific and legal-administrative – underpin environment protection. By unraveling the course of regulatory disputes, I demonstrate that bureaucracies are not just hierarchically divided but are also segmented by horizontal, functional specializations. There is thus an inherent ambiguity lodged between environment as a technical discourse and as statecraft. This ambiguity both fosters and constrains democratic participation in policy decisions and can even partially disrupt power relations in unanticipated ways. © 2021 SAGE Publications.
