Social Versus Private Efficiency: A Comparison of Conventional and Organic Farming Systems in Vineyard Production

Organic farming may be seen as an alternative approach to agriculture that tries to integrate environmental concerns in management practices. By means of DEA, in this work we calculate and compare the efficiency of two samples of conventional and organic vineyards, from two different perspectives: in the first instance, the relationship between inputs and outputs is considered, exclusively, that is, the private efficiency; in the second instance, social efficiency is calculated, and the environmental impacts arising from the activity are also included. The comparison of the results obtained in these two scenarios allows us to draw some conclusions on the efficiency of organic farming in dry-farming conditions.
