The advent of modernity and its conception of knowledge demanded a strong specialization, an intention of universalization and the neutrality of subject and object in a self-centered process of methodological constructions. This process was on the base of the modern sciences since its emergence during the seventeen century until the nineteen century. This model of science has received critical positions since the second middle of nineteen century but it was questioned as a paradigm in crisis at the second middle of twentieth century when the debate about the crisis of the modernity has opened theory conditions to talk about the emergence of interdisciplinary subjects and other paradigms to understand it. One example of it was the emergence of environmental phenomena. After the impact of the Second World War, the environmental sciences as an interdisciplinary approach arise and will propose an effective communication among knowledge in order to offer a more complex perspective since its emergence in the global context. Nevertheless, the legitimization of the new perspective has not become effective because the power relations and the scientific actions on institutions - mainly in universities - have received interference of their disciplinary powers in which is predominant a modern scientifically perspective. This paper aims at discuss the emergence of environmental phenomena and its institutionalization process at the State University of Southwestern Bahia, understanding the scientific actions of researchers and professors as discursive practices in accord with Michel Foucault theory framework.
