The definition of agriculture sustainability considers different aspects. Their main values are the productive systems' internal resources, as they are the way to maintain these systems and, consequently, its productivity through time. In this paper we measure rural producers' sustainability with Data Envelopment Analysis models (DEA) with weights restrictions. This approach considers multiple dimensions and is a relative measure of efficiency. We used a model in which we explore the economic-environmental performance (variables: total area, employment, costs, net income, forested area), in two periods of time, the years of 1986 and 2002.
