A Cost-Benefits Analysis for Risk Management in a Biological Farm

In order to assess the positive and negative impacts associated with the agricultural products it is inevitably necessary to make use of a large number of variables which characterize completely the changes taken in the production process. So, it is necessary to use an appropriate mathematical instrument, which is able to synthesize, conveniently, the results obtained in a representational space with dimension more limited than those used initially; retaining, however, as far as possible the informations obtained by the data of leaving. In this paper we propose a methodological approach that is able to solve the problem for the risk analysis in agricultural firm.
