Resumo: | In 2006, more than 34% of Cerrado biome was already converted to pastures, according to different spatial distribution patterns. This study aimed to analyze the expansion of cultivated pastures and cattle ranching in the Cerrado, between 1970 and 2006, based on historical studies, IBGE census data, and satellite imagery. To this end, former municipality boundaries were reconstructed, in relation to which, census data was spatialized. It could be observed that the amount of cultivated pasture increased up to the early 80’s, when agriculture started to take over and pastures to be more intensively utilized. It was also noticed that the pastures expanded in different ways, regarding specific biome locations, soil quality, existent infrastructure, and the proximity to consumption markets. In this paper, we also considered pasture degradation, regarding both their spatial patterns and geographical associations. Amounting at least 7% of the entire cultivated pasturelands, degraded pastures represent a major social, economic and environmental challenge to the biome sustainable development. |

Este artigo busca analisar a expansão das pastagens cultivadas e da pecuária no Cerrado, entre 1970 e 2006, baseando-se em estudos históricos, nos censos agropecuários do IBGE e em dados de sensoriamento remoto. Os antigos limites municipais foram reconstituí- dos e os dados censitários foram mapeados. Verificou-se que a quantidade de pastagem cultivada aumentou até meados da década de 1980, quando começou a competir com a agricultura e a ser usada mais intensivamente. Notou-se ain- da que as pastagens se expandiram de formas diferentes em cada porção do bioma e que a qualidade dos solos, a presença de infraestrutura viária e a proximidade de mercados consumidores influenciaram essa expansão. Apurou-se ainda que as pastagens degradadas hoje representam no mínimo 7% de toda a pastagem, constituindo-se num grande desafio econômico, social e ambiental para o desenvolvimento sustentável do bioma.Universidade Federal Rural do Rio de Janeiro2015-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer reviewedRevisado por paresAvaliado pelos paresapplication/pdfhttps://revistaideas.ufrrj.br/ojs/index.php/ideas/article/view/133Revista IDeAS; Vol. 7 No. 1 (2013): janeiro a junho de 2013; 174-209Revista IDeAS; Vol. 7 Núm. 1 (2013): janeiro a junho de 2013; 174-209Revista IDeAS; v. 7 n. 1 (2013): janeiro a junho de 2013; 174-2091984-98341982-257Xreponame:Revista IDEAS (Online)instname:Universidade Federal Rural do Rio de Janeiro (UFRRJ)instacron:UFRRJporhttps://revistaideas.ufrrj.br/ojs/index.php/ideas/article/view/133/132Copyright (c) 2013 Elaine Barbosa da Silva, Laerte Guimarães Ferreira Júnior, Antonio Fernandes dos Anjos, Fausto Miziarahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessda Silva, Elaine BarbosaJúnior, Laerte Guimarães Ferreirados Anjos, Antonio FernandesMiziara, Fausto2020-06-15T22:18:37Zoai:ojs.revistaideas.ufrrj.br:article/133Revistahttps://revistaideas.ufrrj.br/ojs/index.php/ideasPUBhttps://revistaideas.ufrrj.br/ojs/index.php/ideas/oairevistaideas@gmail.com||1984-98341982-257Xopendoar:2020-06-15T22:18:37Revista IDEAS (Online) - Universidade Federal Rural do Rio de Janeiro (UFRRJ)false |
