TAXAS DE DESMATAMENTO E PRODUÇÃO AGROPECUÁRIA EM GOIÁS - 2003 a 2007 (deforestation rates and agricultural production in Goiás - 2003 a 2007)
Abstract
Neste trabalho avalia-se o uso de taxas de desmatamento para uma melhor compreensão do processo de ocupação e uso da terra no bioma Cerrado. Para tal, foram analisadas as taxas de desmatamento para os municípios do estado de Goiás referentes ao período de 2003 a 2007, as quais foram correlacionadas com a distribuição espacial da produção agrícola no estado. Este estudo mostrou que as taxas de desmatamentos mantêm estreita correlação com a distribuição espacial das principais commodities agrícolas. Porém, os resultados também sugerem cautela quanto ao uso de taxas para a previsão de cenários futuros, visto que estes são, geralmente, baseados em taxas estáticas, independentemente das significativas variações temporais e espaciais observadas e da interveniência de fatores políticos e sócio-econômicos.

ABSTRACT
In this work we evaluated the use of deforestation rates for a better assessment and understanding regarding land use and occupation in the Cerrado biome. In particular, we analysed deforestation rates for the state of Goiás, on a municipality basis, for the 2003 – 2007 period, which were correlated to the respective agricultural spatial distribution. This study demonstrated that deforestation rates are closely related to the spatial distribution of major agricultural commodities. Nevertheless, our results also suggest caution regarding the use of these rates for predictive scenarios, which are often based on single figures, in spite the fact that rates are subject to significant spatial and temporal variations, mainly due to the influence of political and socioeconomic factors.
Key words: Keywords: Cerrado. deforestation rate. agricultural frontier.
RÉSUMÉ
Sur cet article, nous évaluons l’utilisation des taux de déforestation pour une meilleure comprehension du procès de ocupation et l’utilisation des terres dans le Cerrado. À cette fin, nous avons analysé si les taux de déforestation pour les municipalités de Goiás dans le période 2003 a 2007, qui ont été corrélées avec la distribution spatiale de la production agricole dans l’État. Cette étude a montré que les taux de déforestation mainteint une corrélation étroite avec la distribution spatiale des principaux produits agricoles. Touefois, les résultats suggèrent prudence quant à l’utilisation de taux pour la prévision des scénarios futurs, puisque elles sont généralement basée en taux statique, indépendamment des significatives variations temporelles et spatiales observée et intervenant de facteurs politiques et socio-économiques.
Mots Clés: Cerrado goiano. taux de déforestation. frontière agricole.
