The coverage classification parameters set out in the Corine Land Cover methodology adapted for Colombia were followed, within the established period (2005-2020), and the legend of agricultural land uses of the Rural Agricultural Planning Unit (UPRA). In the results, a total of 16 coverages were obtained for the year 2020 and 13 units for the year 2005. Regarding land use for this period, there were a total of six uses (residential-commercial, livestock, agricultural, agricultural, forestry and agroforestry). Based on the above, 15 types of change were identified, both for coverage and land use, which allowed establishing nine causes with the factors that caused these changes.
