This article aims to present the environmental history of the Cerrado (the Brazilian tropical savannah) as a biogeographic system and the environmental consequences of the agricultural frontier expansion in central Brazil. The research based on a diverse set of documentary and bibliographic sources that highlight the Cerrado landscapes, its biodiversity, with emphasis on the historical processes of agricultural frontier expansion. This is a theoretical-methodological assumption of environmental history study to understand the relationship between society and the Cerrado ecosystem. The results... Mehr ...

This article aims to present the environmental history of the Cerrado (the Brazilian tropical savannah) as a biogeographic system and the environmental consequences of the agricultural frontier expansion in central Brazil. The research based on a diverse set of documentary and bibliographic sources that highlight the Cerrado landscapes, its biodiversity, with emphasis on the historical processes of agricultural frontier expansion. This is a theoretical-methodological assumption of environmental history study to understand the relationship between society and the Cerrado ecosystem. The results show the understanding of the Cerrado as biogeographic system is complex and the different historical processes of perception, description and occupation of this ecosystem happens in a varied way, considering the landscapes diversity and the natural elements that compose it. In addition, the governmental efforts in scientific development to make the Cerrado an agricultural frontier as well as the agricultural expansion of the last 50 years have significantly changed its landscapes, generating impacts and irreversible environmental damage to this unique ecosystem in the central plateaus of South America South. ; Este artículo tiene como objetivo presentar la historia ambiental del Cerrado (la sabana tropical brasileña) como un sistema biogeográfico y las consecuencias ambientales de la expansión de la frontera agrícola en el centro de Brasil. La investigación se basó en un conjunto diverso de fuentes documentales y bibliográficas que destacan los paisajes del Cerrado, su biodiversidad, con énfasis en los procesos históricos de expansión de la frontera agrícola. Est es un estudio teórico-metodológico del historia ambiental para comprender la relación entre la sociedad y el ecosistema del Cerrado. Los resultados muestran que la comprensión del Cerrado como sistema biogeográfico es compleja y los diferentes procesos históricos de percepción, descripción y ocupación de este ecosistema ocurren de manera variada, considerando la ...
