             abstract = "Agriculture and pastures are an important sector of the Brazilian 
                         economy, especially in relation to the production of commodities 
                         that aims to serve the world market. Livestock production in 
                         Brazil is characterized by extensive management, at the landscape 
                         level, which confers low animal production per unit area. Due to 
                         the diversity of genera of grasses (Andropogon, Brachiaria, and 
                         others), different management, spatial location, relief, soil and 
                         climate, produce a mapping of pasture areas in Brazil through 
                         satellite images is a complex process. Thus, this analysis aims to 
                         present the synthesis and evolution of the pasture area in Brazil 
                         based on the different mapping initiatives, as well as to evaluate 
                         the spatial accuracy of these current mappings. The increase of 
                         pasture area in Brazil between 2002 and 2014, according to the 
                         most recent mappings, was 14,542,120 ha, evolving from 151,519,048 
                         ha (PROBIO) to 166,061,167 ha. The Brazilian states that presented 
                         the greatest expansion of the pasture area were Mato Grosso (11 
                         Mha), Maranh{\~a}o (5,2 Mha), Par{\'a} (3,3 Mha), Tocantins (2,8 
                         Mha) and Rond{\^o}nia (2,7 Mha). The states of Goi{\'a}s, Minas 
                         Gerais and Mato Grosso do Sul, important producers of livestock in 
                         Brazil, there was a considerable retraction of the pasture area, 
                         on average of 2 Mha. The average accuracy of the mappings that 
                         compose the mapping of the pasture area to the Brazilian territory 
                         is medium-high, approximately 73%.",
