The environmental law has cemented its epistemic bases, on the basis of the struggle for the establishment of environmental sciences in Latin America, which has had to overcome epistemological and disciplinary barriers which have made it possible to clarify its object of study in universities. In the course of the formalization of the environmental sciences, these have defined their disciplinary action toward the solution of environmental problems; while the paradigm of sustainability, through the legal axiology, has revised its character of autonomous subject in front of the regulated: the environment. However, in the Colombian and Chilean university organizations, there is not a conceptual unit of the field of environmental law. Cognitive boundaries between disciplinary and interdisciplinary, and the organization from and for the field of the environmental problem, do not seem to be settled in the region. Despite the struggles for its character of scientificity and of having a constitutional recognition, where environmental rights are conceived as human rights, the universities are not prepared to develop it; therefore, there is a low incorporation of environmental law in the curricula of undergraduate in law schools.
