The industrialization of the agricultural sector has resolved, at least in Europe and in the United
States, the thousand year-old problem of the lack of food. Unfortunately, during the last years the
limits of such an agriculture clearly exploded. The modernized agriculture, in fact, produces
negative externalities and it does not assure food safety.
Through our contribution we hypothesize three future scenarios for modernized agriculture. We
shall study in particular the one that foresees the conversion to sustainability through the return of
traditional techniques. In order to analyze the problem, we shall introduce the Sraffian framework
of the “re-switching of techniques”. Finally we shall build an original and new model of “reswitching”
for the short period.
The aim of our work is to show that, at least theoretically, it is possible that a traditional agricultural
technique could be convenient in a context of both low and high profit level
