Abstract
ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units considered “homogeneous” to be distinguished, as a result of interaction between physiographic conditions. The aim of this study was to evaluate potential for erosion in Sao Miguel do [...]
Highlights
The Cerrado is Brazil’s second largest biome in area, occupying 2,000,000 km2, or 23 % of the country’s territory (Ribeiro and Walter, 2008)
Based on the assumption that land use and occupation have affected linear erosion in Cerrado Biome, this study aims to use morphopedological compartmentalization to assess the erosion potential in the municipality of São Miguel do Araguaia in northwestern Goiás, Brazil
The study was conducted in the municipality of São Miguel do Araguaia, in northwestern Goiás, Brazil, located in the Araguaia river basin (Figure 1)
Summary
The Cerrado (broadly, Brazilian tropical savanna) is Brazil’s second largest biome in area, occupying 2,000,000 km, or 23 % of the country’s territory (Ribeiro and Walter, 2008). This biome has a vegetation complex with a wide diversity of phytophysiognomies, including forests, bushland, and fields, divided into several subtypes (Ribeiro and Walter, 2008). Encompassing the entire state of Goiás, the Cerrado has been degradated to various degrees, mainly from agricultural expansion, resulting in the loss of native vegetation. In 2007, the municipality of São Miguel do Araguaia had a deforested area of approximately 924 ha, representing 15 % of its territory (Silva and Ferreira Júnior, 2010)
