                         avaliar as taxas de perda de solo na Bacia do Rio Curu{\'a}-Una, 
                         sudoeste do Par{\'a}, de 1984 a 2014. Essa regi{\~a}o tem 
                         sofrido grandes altera{\c{c}}{\~o}es na cobertura florestal 
                         desde a d{\'e}cada de 70 e, mais recentemente, sofreu o impacto 
                         da expans{\~a}o do agroneg{\'o}cio, que ocorreu 
                         preferencialmente nas {\'a}reas de planalto. Diferentes tipos de 
                         modelo t{\^e}m sido utilizados para estimar perda de solos. Nesse 
                         estudo, utilizamos o modelo USLE e diferentes tabelas de 
                         refer{\^e}ncia para estimar fatores associados {\`a}

                         mudan{\c{c}}as de UCT foram identificadas, e uma an{\'a}lise 
                         combinada das mesmas foi realizada. Os resultados mostraram que as 
                         taxas de perda de solo na Bacia de Curu{\'a}-Una aumentaram 243% 
                         de 1984 a 2014, com as maiores incertezas associadas {\`a}s 
                         mudan{\c{c}}as de UCT e os fatores de erodibilidade. As 
                         trajet{\'o}rias da UCT mostraram uma maior remo{\c{c}}{\~a}o da 
                         cobertura vegetal no munic{\'{\i}}pio de Uruar{\'a}, que possui 
                         relevo acidentado e cobertura de pastagens dominantes, e nos 
                         munic{\'{\i}}pios de Belterra, Moju{\'{\i}} dos Campos e 
                         Santar{\'e}m, em uma {\'a}rea de cultivo anual plana. Nestas 
                         {\'a}reas, ocorreram maiores taxas de perda de solo pr{\'o}ximo 
                         {\`a} barragem de Curu{\'a}-Una, indicando poss{\'{\i}}veis 
                         impactos nos corpos d'{\'a}gua. A an{\'a}lise revelou 
                         padr{\~o}es importantes de perda de solo e vegeta{\c{c}}{\~a}o 
                         que devem ser considerados no planejamento ambiental territorial e 
                         poderiam ser usados como um guia para a defini{\c{c}}{\~a}o

                         carried out in the 1960s and 1970s aiming to integrate the Amazon 
                         region into south-eastern Brazil resulted in an intensive 
                         migration and the development of huge projects, which trigged the 
                         conversion of vast areas of forest cover into different types of 
                         land cover and land use (LCLU). Changes in LCLU can affect 
                         biodiversity, increase greenhouse gas emissions, and impact water 
                         quality through erosion, sedimentation and eutrophication. The 
                         identification and monitoring of the most susceptible areas to 
                         changes in LCLU could support public policies and territorial 
                         planning. Following this approach, the objective of this study was 
                         to evaluate the soil loss rates at Curu{\'a}-Una River Basin, 
                         southwest of Par{\'a} state, from 1984 to 2014. Since 1970s, the 
                         forest in this area has been impacted by human activity, and 
                         recently, also by agribusiness expansion, which occurred 
                         preferentially in plateau areas. Different models have been used 
                         to estimate soil loss rates. In this study, the Universal Soil 
                         Loss Equation (USLE) was used with different data sources of 
                         erodibility and LCLU values. LCLU and soil loss rates trajectories 
                         were identified, and a combined analysis of them was carried out. 
                         Results showed that soil loss rates in the Curu{\'a}-Una Basin 
                         have increased by 243% from 1984 to 2014, with the highest 
                         uncertainties associated with the LCLU and the erodibility 
                         factors. The LCLU trajectories showed a greater removal of 
                         vegetation cover in Uruar{\'a} municipality, which has a rugged 
                         relief and pastureland cover dominant, and in Belterra, 
                         Moju{\'{\i}} dos Campos and Santar{\'e}m municipalities, on a 
                         flatted annual crop area. In these areas, occurred increased soil 
                         loss rates near Curu{\'a}-Una dam indicating potential impacts in 
                         the water bodies. The analysis revealed important patterns of soil 
                         and vegetation loss that should be considered in territorial 
                         environmental planning and could be used as a guide for adequated 
                         land use definition that seeks soil, water, forest conservation.",
