What is it about?
Based on the estimates of soil loss in pasturelands of Goiás State and the Federal District, the effects of land use and management and conservation practices on soil erosion by water were evaluated. Soil loss was estimated with the RUSLE under four scenarios of land use and management of pastures and the implementation of terraces.

Why is it important?
Pasture degradation is one of the major environmental and economic problems of Brazilian livestock production. The environmental consequences of pasture degradation become particularly important when they are associated with land use in the Amazon and Cerrado biomes because farmers in these regions are forced to open new natural areas. Well-managed pastures planted in terraces and highly sloped areas with native vegetation featured a reduction of 709% in the rate of soil erosion by water in comparison with poorly managed pastures without soil conservation practices.
Perspectives
The results of these simulations demonstrate the importance of actions to recover degraded pastures, such as the Federal Government’s program known as ABC (Low Carbon Agriculture).
