Bibliometria da pesquisa brasileira em erosão acelerada do solo: instituições, temas, espaço e cronologia

Abstract: RESUMOApesar do constante aumento na quantidade e diversidade de publicações acerca da erosão do solo no Brasil e no mundo, as grandes questões dessa ciência ainda não foram respondidas. Os possíveis motivos desse descompasso trazem à tona a necessidade de discutir o papel da pesquisa em erosão. A bibliometria permite uma visão abrangente da ciência, fornecendo perspectivas, contudo estudos que fazem uso dessas técnicas são escassos no mundo, bem como no Brasil. Os objetivos deste trabalho foram analisar as di… Show more

“…This algorithm has been used in numerous studies worldwide (e.g. Martín-Fernández and Martínez-Núñez, 2011;Valle Junior et al, 2010a), representing about one third of soil erosion assessments in Brazil (Barretto et al, 2009). Apart from conventional estimations of soil losses, the USLE has recently been used to investigate potential amplification of these losses resulting from the so-called environmental land use conflicts (Pacheco et al, 2014;Valle Junior et al, 2014a), which mean uses not conforming to land capability (the soil's natural use).…”

“…A Equação Universal de Perda de Solo (USLE) (Wischmeier & Smith, 1978) é um modelo empírico de estimativa da perda de solo, amplamente estudada, conhecida e utilizada no mundo para predizer as perdas de solo por erosão (Hudson, 1995;Silva, 2004;Cassol et al, 2008;Barretto et al, 2009;Mazurana et al, 2009;Oliveira et al, 2012). A USLE estima a perda de solo anual (A) por meio da combinação dos seguintes fatores: erosividade da chuva e enxurrada associada à chuva (fator R); erodibilidade do solo (fator K); comprimento de rampa (fator L); declividade do terreno (fator S); cobertura e manejo do solo (fator C); e práticas conservacionistas de suporte (fator P), resultando na equação:…”

“…However, few studies have tried to give a historical perspective on this important phenomenon (Barretto et al, 2008(Barretto et al, , 2009Farias, 2010;Camargo et al, 2010). Basic questions, such as when and why research on soil erosion in Brazil began, are not satisfactorily answered in the literature.…”
