RESUMO

This study presents the methodology of construction of the Agricultural Environmental Sustainability Index (ISAGRI). This Index was evaluated in the watersheds of the rivers Oriçanga and Araras, both belonging to the Mogi Guaçu river basin. This is a representative area of different situations found in the State of São Paulo. The region presents practically all the great geomorphic provinces of the State, with great variation of ground, topography and vegetation. It also presents a diversity of agricultural systems, with the most varied uses of the ground and different types of agriculturists. The methodology of the ISAGRI was constructed using the theoretical target of indicators of state, pressure and response (PER) considered by the OCDE. The ISAGRI is synthetic index composed of 8 indicators divided in 3 dimensions: state, pressure and response. These indicators have been transformed into indices, and then, added to the dimensions to which they belong, thus generating three new indices - IEA (Index of state of the agricultural ecosystem; IDEG (Index of degradation vectors) and ICOR (Index of measures of prevention and correction). The ISAGRI is thus, the result of the simple average of the indices of these dimensions. The test allowed the comparison of the levels of agricultural environmental sustainability between the two watersheds, being that the Araras?s watershed presented the best results and, therefore, better environmental sustainability. At the end, the different levels of sustainability were categorized in criteria of sustainability
