             abstract = "The agriculture is very important for Brazilian economy, and its 
                         growth was very fast during the last decades. However, the fast 
                         growth of the agricultural sector has caused some negative impacts 
                         on the natural vegetation cover. This work aims to discuss the 
                         historical agricultural expansion of Lu{\'{\i}}s Eduardo 
                         Magalh{\~a}es (LEM) municipality located at the west part of 
                         Bahia State, Brazil, over the last 22 years (1984 to 2006). Also, 
                         it is analyzed the possible direct impacts caused by agricultural 
                         expansion over local vegetal coverage: the savanna. The values 
                         obtained for the agricultural area used pointed towards a fast 
                         growth of this sector in the county. The combination of these two 
                         factors (soils and relief) yielded a good environment for the 
                         establishment of agricultural activities in a commercial scale. 
                         The {"}agricultural polygons{"} generated presented different 
                         sizes and forms. Initially, agricultural area was 4.22%, growing 
                         up to the current figures of more than the half of the municipal 
                         area (54.46%). The direct impact caused by the fast agricultural 
                         expansion was the suppression of local vegetation coverage 
                         (Savanna). Such suppression was about 201,702.7ha, including the 
                         Permanent Preservation areas. The only Environmental Conservation 
                         Unit (APA) located in LEM revealed a great efficiency in the 
                         maintenance of the native vegetation. Such fact is noticed by the 
                         presence of the greatest untouched savanna polygon of LEM 
                         (72,724.2ha).",
