In Brazil and in the world, irrigated agriculture has been a field of activity of vast expansion, producing foods present in the Brazilian table and that are exported outside the country, from that, Rio Paranaíba - MG, occupies the ranking of municipalities with greater advance in irrigated areas in the country, therefore, showing great growth over the years, which shows that it is not compatible with the collective water grants declared and described by the environmental agency. Through the NDVI, resulting from the processing of CBERS4 satellite images, it was possible to evaluate the growing number of pivots in the municipality, and showing that it is not compatible with what is declared in grants, which can be explained is that the grant has a validity of 10 years, so the producer already foresees future steps. With this, what could be better developed would be their annual update, so that there is greater control, and also the information of the other types of declarations is available for consultation.
