Meanwhile, the construction and selection of indicators are relatively complicated and usually restricted due to several factors theoretical and methodological. The study aimed to identify and analyze the indicators commonly used in the analysis of the environmental sustainability of agroecosystems, comparing aspects perceived as more relevant. They did a literature review selecting, through analysis of accessibility, studies on environmental indicators, published from 1999 to 2005. The studies were analyzed based on Camino and Muller (1993) and in March for environmental indicators "Pressure-State-Response" PER-OECD. It was a total of 216 indicators in the 11 studies analyzed. Almost 96% of these indicators to tackle internal aspects agroecosystems, with 66% referring to resources endógenos and about 30%, the operations developed internally. Approximately 55% focusing on the conditions of resources, just over 28% and impacting the shares, 17% initiatives for recovery / mitigation of the state of degradation. There is a variety of indicators and methodologies available to assess the environmental sustainability of agroecosystems, which makes the studies in this area very complex and specific and difficult to reapplication in different realities.
