Despite the increasing number and diversity of publications related to soil erosion in Brazil and throughout the world, the central questions of this science remain unanswered. The possible reasons for this imbalance highlight the need to reconsider the role of research on soil erosion. Bibliometric studies can provide ample view of the research field, describing perspectives, but research using this approach is scarce in international as well as in Brazilian literature. The objective of this study was to analyze the […]

Bibliometrics, history and geography of Brazilian research on accelerated soil erosion

Soil science history studies are rare and the Brazilian scientific community has not given substantial attention to this subject yet. The present study focused on the formation of research on accelerated soil erosion in the Brazil from a bibliometric perspective. A comprehensive database of published scientific papers was organized in a relational database and analyzed by SQL queries and GIS tools. These data were used to calculate quantitative indicators and spatial distribution patterns. Results indicate a recent development of research […]

Information Systems store detailed information on land resources, so that these can be accessed, combined, and analyzed for several purposes from different points of view. In Brazil, the information produced in soil surveys has not been efficiently made available, due to the great volume, complexity, and little standardization. Thus, with the objective of enabling the storage, manipulation, and disposal of information on Brazilian soils, the SigSolos System was developed. SigSolos was structured to allow the storage of information originated from […]
