UMA ABORDAGEM SISTÊMICA PARA A AGROPECUÁRIA E A DINÂMICA EVOLUTIVA DOS SISTEMAS DE PRODUÇÃO NO NORDESTE SEMI-ÁRIDO

Abstract

The human specie has always been developing and improving its ways of exploring the natural resources. Among these ways, farming stands out for including various activities which are moving according to the time and space where they are implemented, which makes necessary to consider and study farming as a system. In this work, the concept of farming system was set up, showing that it is formed of several parts that interact with each others and with external components, generating a dynamic. To facilitate the comprehension of the current farming systems in the semi-arid northeast of Brazil, a revision of the evolutionary paths of these systems was done, considering livestock like a subsystem of the sugarmills, and of its importance in the economy and culture of the northeast. Observations about the fragmentation of the land and the appearance of systems of family production were also conducted. This study draws the conclusion that besides the physical characteristics of the area, some socio-political and economical factors have influenced a lot the way in which the farming systems were constituted in the semi-arid northeast.
