Avaliação Da Sustentabilidade De Propriedades Rurais Na Região Do Oeste Paulista

Abstract

This work aims to relate the characteristics observed in different agricultural properties with data obtained by satellite images. The data consist of spectral indices and surface temperature. Beside this, a questionnaire was applied with the person in charge of each property. Finally, soil samples were collected at a depth of 0 to 10 cm, and the moisture, dehydrogenase and respiration contents were analyzed. A comparison of the results suggests that the properties do not meet the basic requirements of a sustainable agriculture. This idea is reinforced by the values presented by the indices, which indicate a low coverage of local vegetation, low humidity in leaves and high surface temperatures found for each of the properties studied.
