Resumo
Nowadays sustainability has become one of the major topics of interest in farming systems research. Farming systems
sustainability is analyzed in this work by introducing the concept of technical sustainability, defined here as the ability
of a biological production system to make an efficient use of the available resources on field level with the main goal to
maximize its economic output given a set of uncontrolled biophysical constraints. This concept is developed and applied to
the agricultural production area of the Mantaro Valley (Peru). Through fortnightly visits, data on biophysical characteristics
of the crops on selected production fields were collected without taking part in the decision process of the growers to manage
their crops. Afterward, by applying a multivariate exploratory data method, principal component analysis, it was possible to
establish technical efficiency gradients for the tested data. The capabilities of such type of analysis are explored by studying
two types of standardization of the collected data. The biplot graphical output that can be built upon the results of the analysis
represents an extra powerful feature to interpret the outcome of the analysis.
