“…Indeed, this is due to several reasons such as conventional plowing, removal of the original vegetation, use of pesticides and herbicides that damage biological activity in soils (Freemark and Boutin, 1995;Johnsen et al, 2001;Pelosi et al, 2013), low overall vegetation cover, soil compaction and sealing due to machinery traffic, depletion of organic matter and absence of soil erosion control measures (Arnáez et al, 2015;Bakker et al, 2005;Carr et al, 2015;Cerdà et al, 2009;Ciampalini et al, 2012;Cots-Folc et al, 2009;Laudicina et al, 2015;Raclot et al, 2009;Tarolli et al, 2014Tarolli et al, , 2015. The effect of intensive agricultural practices on soil erosion is now well known and is concerning given evidence that civilizations have collapsed throughout human history due to erosion (Brevik and Hartemink, 2010) and that erosion continues to negatively affect civilizations in all regions of the world (Brevik, 2009a;Brevik et al, 2015;Cerdà and Doerr, 2007;O'hara et al, 1993;Pimentel et al, 1987;Shi and Shao, 2000;Smith et al, 2015). Therefore, there is a need to find best management practices that will make agriculture sustainable.…”

“…Soil erosion is a serious environmental problem that has adversely affected the world food production through the reduction of land productivity and water availability [1]. Erosion is a natural geomorphic process resulting from removal topsoil by wind and water [2], and it can be influenced by several factors such as climate variables, slope steepness, soil physical parameters, vegetation and land use patterns [3].…”

“…Moreover, erosion process can be intensified by human intervention through inappropriate land use and land cover changes. In this context, severe soil erosion has occurred in the world's major agricultural regions and the problem has increased as agricultural activities intensified grown in the forest fringe areas [1].…”

Soil erosion is a serious environmental problem that has adversely affected the world's food production through the reduction of land productivity and water availability. The present study estimated annual soil loss rate and its spatial distribution in the most important Brazil's agricultural region, the Brazilian Cerrado, using Revised Soil Loss Equation (RUSLE) model into Geographic Information System (GIS) framework. For this purpose, the soil erosion annual rate was determined in function of RUSLE model factors: rainfall erosivity (R), soil erodibility (K), topography (LS), crop management (C) and supporting conservation practice (P). All factors were obtained from literature. They were processed and integrated into a GIS, resulting in a map of annual soil loss rate. The methodology applied showed acceptable precision and it was possible to identify the most susceptible areas to water erosion. The average estimated rate of soil loss for the entire Cerrado was 12.8 t•ha . Except for annual crops, all farm and silviculture areas showed average soil loss ranging from moderate to high rate. These results suggest that the implementation of more effective management techniques and conservation practices are necessary for the Cerrado to maintain and to improve land productivity by ensuring national and international food demands.

“…Changes in land use are widely recognized as capable of greatly accelerating soil erosion (14)(15)(16), and it has long been recognized that erosion in excess of soil production would eventually result in decreased agricultural potential (2,3,(17)(18)(19). Although soil fertility generally declines with accelerated erosion, soil fertility is itself a function of agricultural methods and site conditions such as soil type, nutrient, and organic matter content.…”

Data drawn from a global compilation of studies quantitatively confirm the long-articulated contention that erosion rates from conventionally plowed agricultural fields average 1-2 orders of magnitude greater than rates of soil production, erosion under native vegetation, and long-term geological erosion. The general equivalence of the latter indicates that, considered globally, hillslope soil production and erosion evolve to balance geologic and climate forcing, whereas conventional plow-based agriculture increases erosion rates enough to prove unsustainable. In contrast to how net soil erosion rates in conventionally plowed fields (Ϸ1 mm/yr) can erode through a typical hillslope soil profile over time scales comparable to the longevity of major civilizations, no-till agriculture produces erosion rates much closer to soil production rates and therefore could provide a foundation for sustainable agriculture.agriculture ͉ civilization
