Abordagem sistêmica e potencial em taninos de espécies de ocorrência no Semiárido Brasileiro.

Abstract

The present study sought to adapt the line of systemic thinking to exceed the questioning of the academic area. Therefore, to accomplish this journey, the work here was divided into two approaches, one systemic and one eminently scientific. At first, it was recognized that the processes of exploitation of natural resources are affected by a crisis of perception and it believes in change from thoughts and values through discussion. After, it was prepared an emergency production manual of vegetable tannins present in semi-arid species, prepared since four-year ago study, in order to provide other new potential species to ensure the permanence of this activity and the financial independence of families who survive on the basis of this practice. This work concludes that it’s necessary to reconstruct the man's Northeast identity; it is from there that he will be able to seek the incorporation of new values and principles as a way to adapt them to the reality of the semi-arid region where he lives. Moreover, species of Mimosa tenuiflora (Willd.) Poir., and Anacardium occidentale Linn can be used for the leather activity to reduce the shortage of Anadenanthera colubrina var. cebil species.
