Abstract

In the Northern Cerrado, increasing pressure from Society on Nature has intensified existing problems, such as the loss of soil in productive areas. This article evaluates the spatial and temporal variability of soil loss in the periurban area of São Desidério (BA), one of the largest grain producers in the country, and its relationship with the land tenure structure and the consolidation of agribusiness in the region. For this purpose, the Revised Universal Land Loss Equation – RUSLE – was calculated for the years 1990, 2000, 2010 and 2020, for each rural property, classified by rural module size. Small properties have higher soil loss rates, followed by micro, medium and large properties. During the period, there was a general trend towards an increase in soil loss around 50%. The micro and small properties had average rates twice as high compared to the medium and large ones, showing the need to improve soil management practices.
