The knowledge deficit model with regard to the public has been severely criticized in the sociology of the public perception of science. However, when dealing with public decisions regarding scientific matters, political and scientific institutions insist on defending the deficit model. The idea that only certified experts, or those with vast experience, should have the right to participate in decisions can bring about problems for the future of democracies. Through a type of "topography of ideas", in which some concepts from the social studies of science are used in order to think about these problems, and through the case study of public participation in the elaboration of the proposal of discounts in the fees charged for rural water use in Brazil, we will try to point out an alternative to the deficit model. This alternative includes a "minimum comprehension" of the scientific matters involved in the decision on the part of the participants, using criteria judged by the public itself.

The discussion on the state of the art of scientific publications in Latin American countries generally restricts itself to its supposedly low visibility. This affirmation is generally conditioned to the exclusive use of large international databases, mainly of the USA and Europe, which include thousands of scientific publications that have marginalized a large part of the scientific literature produced in peripheral countries. Given this fact of low visibility, it became imperative for some Latin American countries, beginning in the 90s (20th Century), to develop their own mechanisms of projection of the results of their own scientific production. The experiences constitute an example for countries that, having significant scientific production, still do not have the means to facilitate access to local scientific publications. Although Bolivia still remains distant from these initiatives, a series of studies were identified that show the existence of a tradition of publication in scientific magazines and interest in their visibility, on a local and international level, which demands attention to the most adequate mechanisms in order to carry this out.
