Several resources we need to live come from the soil, which is essential for the existence of the terrestrial environment where we exist. However, with the advancement of anthropic activities, it is currently possible to observe a change in temporal and spatial level. This study aims to analyze the changes in land use and land cover from 2013 to 2018 in the municipality of Castanhal-PA. Remote sensing products, both orbital images and aerial photographs, are of utmost need to analyze the process of planning and restructuring the environment. The study area is located in the municipality of Castanhal. It is estimated that in 2016 the municipality had 192,571 inhabitants, with an area of 1,028,889 km2. LANDSAT 8 / TM orbit-point sensor satellite imagery 223-061 was used. The images were obtained from the United States Geological Survey platform and the images were processed using ArcGIS 10.5 software and land use classes were identified with qualitative analysis, recognizing targets in the images that represented the desired classes. It is noted when comparing the map of the municipality of Castanhal of 2013 with the year 2018 that arable areas and areas of exposed soil increased, consequently causing a decrease in dense and secondary vegetation areas. In 2014, the main exported product was the black pepper, being Castanhal the largest exporter, that is, for the municipality to increase its productivity it is necessary to open new arable areas and exposed soil. Several factors contribute to the increase of areas with exposed soil, such as the opening of roads, livestock, housing, as well as arable areas, thus being approved in 2018 the bill that creates the Castanhal Municipal Natural Park. During the study period the areas of dense vegetation and secondary vegetation were not superior to the anthropized areas. It is noted that over five years (2013-2018) there was an increase in exposed soil areas, caused by the increase in deforestation in the municipality, in addition to the growing increase in arable areas thanks to the growth of agriculture. The growth shows how the disorderly anthropic actions cause impacts on the environment. From the data obtained it can be seen the importance of implementing a sustainable use and occupation management plan in the area and a better management of natural resources.
