Um ciclo comum na evolução dos sistemas agrícolas contemporâneos

Resumo

The purpose of this article is to show that, as part of a unique system, the
agricultural policies of all developed countries went through a "cycle" which
initiated in the twenties and extended to the present decade, but that several facts
seem to indicate that this cycle is coining to an end. Four phases can be distinguished
within the cycle. During the first phase there occured a wide reorganization of the
primary sector of the industrialized countries by means of a strong State intervention.
During the second phase, and under the leadership of the United States, the
primary sector went through a wide process of modernization. Then carne a phase
of disruption of the hegemonic model, with the gradual loss of the unipolar
character of the world's agricultural alimentary system. The last phase, not yet
entirely over, shows a tendency to a multipolar configuration of the world's
agricultural alimentary system.
