The alcohol sector has shown a remarkable process of expansion since 2000, towards the central Cerrado, admittedly favored by situation anchored in renewable energy and defense of national sovereignty. The state of Goias is one of the prime targets of this expansion, since 2004, primarily from 2006 to 2007, and has been concentrating a strong sugar industry in southern Goiás / Southwest Microregion of Quirinópolis (MRQ), where he spent about 4 000 ha more than 150 000 ha planted in the period, with great impact on the local socio-economy, according to previous studies, and subsidiaries of this thesis. This micro-region has favorable soil and climatic characteristics and economic importance of high logistics intra-and inter-regional exports, but the changes in land use and environmental impacts related to this process are still poorly studied. This thesis aims to understand the spatial pattern of expansion of sugarcane and the MRQ, with emphasis on soil and its use changes, considered by many authors as the agricultural frontier expansion of the 1970s, but more organized and capitalized technified, aiming prove the hypothesis that there has been setting a new centrality of the sugarcane industry in the Cerrado, focusing on production of ethanol and bio-energy, multi-scale consequences of which affect, among other things, the other pre-existing supply chains, especially food production. We analyzed in more detail the succession of land uses in the period since 2004, before the arrival of the cane in order to identify the substitution patterns of crops and pastures by the new culture and the potential for direct environmental impacts of sugarcane due observation of pressure on water resources for irrigation purposes and on soils associated with the management system of high technological standards, involving inputs and pesticides, and heavy machinery, among others. The research was based mainly on compiling data and maps, and thematic development of multi-scale cartographic documents, including use of satellite imagery and GIS analysis of census data and detailed study of various impacts on soil and water resources, with sampling Field and laboratory analysis. It is concluded that sugarcane has focused initially on the best land of the MRQ, where it has the best infrastructure in regional / state, where it stood, triumphant, with other uses, in particular, grains (soybeans), and secondarily pastures, in which continues with the current expansion. The process as in the past is supported by federal policy, now the PNE - 2030, and receives federal and state subsidies. It's still fast and plays the same model of previous agricultural expansion, occupation of Savannah in the 1970s, differing, however the fastest and well-planned action of large financial groups and the rapid formation of joint ventures and sugar and alcohol agribusiness complexes horizontal extension of those South-East and even multinationals. These groups previously selected areas where expansion triggered the installation of plants inducing a re-zoning, but retained the strategy of producing agricultural commodities. Finally, it was found that the main direct environmental impacts cultivated areas are the loss of soil biodiversity and water resources soil compaction and increase their resistance to penetration, indicating compression, and it is assumed that there is potential for erosion and also the subsequent contamination of their time, because crop management. It was concluded that MRQ experience, paradoxically, both positive and negative social and environmental impacts arising from a rapidly expanding sugarcane which materialized a new centrality of the space sector in the Central Cerrado, similar to that which occurred in the past the state of São Paulo, but this time relying on an industry already established in the south-southeast and which together make up what is called the polygon of the cane and a new center, as part of this arc expansion of sugar cane, as undeniable and great expression of state and national levels, and gradually reference also becoming international.
