                         resultado, observou-seum ganho de {\'a}rea da LSA no

                         per{\'{\i}}odo de 2000-2010 foi o que apresentou maior ganho 
                         (25%). A expans{\~a}o da LSA se deu primordialmente sobre 
                         {\'a}reas de Pastagens (38%), Vegeta{\c{c}}{\~a}o 
                         Secund{\'a}ria (31%), Floresta (27%) e SSA (2%). Cerca de 25% da 
                         {\'a}rea de SSA de 2000 foi convertida para LSA em 2019. Essa

                         important changes in the Brazilian Amazon due to land 
                         concentration processes, landscape homogenization and expansion 
                         over other forms of production. In Par{\'a}, this process has 
                         occurredmore intensely in the municipalities ofSantar{\'e}m, 
                         Belterra and Moju{\'{\i}} dos Campos, which are part of the 
                         Curu{\'a}-Una river basin. This study aims to analyze the 
                         dynamics of land use and land cover for the period 2000 to 2019, 
                         in the Curu{\'a}-Una River basin, observing which classes 
                         Large-Scale Agriculture (AGLE) has expanded. The current land use 
                         and land cover databases in the Amazon do not include Small-Scale 
                         Agriculture (AGPE)class. To include this class in the mapping we 
                         used TM/OLI/Landsat images with multi-resolution segmentation 
                         techniques and object-oriented classification. For the analysis of 
                         the AGLEdynamics, transition matrices for the periodsof2000-2010, 
                         2010-2019 and 2000-2019 were built. As a result, we observedan 
                         area gain for AGLE in the period 2000-2019, from 23 kmē to 1,093 
                         kmē. The period of 2000-2010 was the one with the greatest gain 
                         (25%). AGLE's expansion took place primarily over pasture (38%), 
                         secondary vegetation (31%), forest (27%) and AGPE (2%). About 25% 
                         of the AGPE area in 2000 wereconverted to AGPE in 2019. 
                         Thatproportion may be even higher, as part of the secondary 
                         vegetation converted to AGLE, is part ofthe AGPE fallow system. 
                         The results reinforce the importance of establishing public 
                         policies valuingand strengtheningthe local economy.",
