             abstract = "By 2030, center pivots should assume the position of Brazil's main 
                         irrigation system. Along with this growth, there will be an 
                         additional water demand of 30 thousand liters/second each year, 
                         which makes sustainability increasingly important. Therefore, the 
                         objective of this work is to develop a methodology to determine 
                         the idleness and seasonality of pivots' use in the irrigated areas 
                         of Paracatu, Minas Gerais. NDVI time series were composed by the 
                         integration of Landsat -8 and Sentinel -2 images, between 2016 and 
                         2019. Series extraction, processing and analysis were performed 
                         using the Python programming language and vector manipulation 
                         using software QGIS. Less than 2% of the total amount of pivots 
                         presented some inactivity fraction each year and the number of 
                         total pivots increased by 15.3%, evidencing the great use of 
                         irrigated areas in the municipality of Paracatu and the need for 
                         monitoring.",
