		<abstract>Erosion is a major source of danger to soils. It is caused by natural agents, like rain, cause damage to crops, soil exhaustion, siltation and pollution of watersheds. Such processes are intensified, in the metropolitan region of Goiânia, by the removal of native vegetation and establishment of pastures and crops. The Universal Soil Loss Equation (USLE), applied by the use of the Geographic Information Systems (GIS), allows to estimate erosion in varying land use conditions. USLE was selected as a methodology with the objective of evaluating the erosive susceptibility to the current ground use and also for the remaining vegetation scenarios transformed into agriculture and pasture, comparing their values to predict how the conversion of environmental asset can collaborate for the occurrence of erosion. Considering that the whole metropolitan area of Goiânia, these ensuing scenarios were simulated: Current, Pasture and Agriculture. The erosive susceptibility to pasture was increased to almost five times and Agriculture over 130 times compared to the Current Scenario. It was observed that the simulated scenarios resulted in an increase of the average soil loss of 3.33 t.ha-1.year-1 and 14.3 t.ha-1.year-1 for Pasture and Agriculture, respectively. The results indicate that the conversion of environmental liabilities demonstrates a significant increase in erosive susceptibility.</abstract>
