Based on the methodology of potential soil fragility, described by Alarcón and Gayoso (1999), the evaluation and spatial distribution of the potential fragility for erosion and  landslides, was carried out in the soils of the municipality of Ibagué. Edaphic variables were taken from units of soils according to two systems of classification: Comité de Cafeteros de Colombia (1973) and IGAC (2004). Environmental variables of precipitation and altimetry were obtained from the hydrographic basin ordination and management plan of the Coello and Torare rivers (CORTOLIMA, 2006) and the forestry planning project for the Department of Tolima (Universidad del Tolima and CORTOLIMA, 2007). According to the numerical information organized in maps and the mathematical models established for the nomograms of the base methodology, the rates of potential fragility of the two phenomena of soil degradation were determined. The results show that with the soil classification system IGAC, the municipality of Ibagué is more sensitive to phenomena of landslides rather than to erosion, opposed to what is shown in the system of the Comité de Cafeteros de Colombia. Both systems coincide in stating that the zones with higher propensity to these phenomena are located mainly near the Combeima Canyon, in the mountainous area near the municipality of Cajamarca, as well as the hills and mountains that surround the urban area
