Pasture areas grown on Quartzipsamments (RQ) at the Alto  Taquari watershed (BAT) are important sources of sediments which intensify the Taquari river´s siltation in Pantanal. The objective of this work was to assess the use of the Linear Spectral Mixture Model (LSMM) in the mapping and characterization of the current degradation level of pastures planted on RQ at BATin terms of erosion risk. Using Landsat 5 satellite images of 2010 and employing the LSMM, we generated an image for exposed soil (ES), which was used along with field work to define three pasture degradation  aAlto Paraguai watershed  aBacia hidrográfica do alto Paraguai  aBioma Cerrado  aCerrado Biome  aGeotechnology  aGeotecnologia  aLinear Spectral Mixture Model  aModelo Linear de Mistura Espectral  aRecuperação de pastagens degradadas1 aMARINHO, M. de A.1 aSILVA, J. dos S.
