"Future scenarios of the modernized Agriculture: the Relevance fo the Hypothesis of the Return of the traditional Techniques": This paper analyses future scenarios for modernized agriculture, foreseeing also the conversion to sustainability through the return of traditional techniques. The re-switching of techniques has been first introduced by Sraffa and Samuelson, but the parametric values were not realistic. In this paper we show that using a perturbation of binomial rates of return it is possible to get also more realistic examples. From a theoretical point of view we show that also multiple re-switching of techniques could happen.
