Although he started a few years ago, your profile (payment for environmental services) and its territorial approach seem to give him a character in the novel that deals with environmental policy in the region. Even very foolishly, he has been successful in solving problems as the service traditional populations, resolution of territorial conflicts and income generation. Regarding the second article deals with the same controversies existing between economic growth, sustainable development and environmental protection, raised from work as Grossman and Krueger (1995) that describe a relationship between GDP per capita and environmental degradation. Thus this paper aims to investigate this relationship through the identification of spatial patterns of variable deforestation in Amazonas and thus more specifically investigate the influence of income on deforestation, from two main interests (1) test the existence of the Environmental Kuznets curve, (2) measure the importance of the Bolsa Floresta program. For this, an econometric model was constructed with data Cross section for the year 2009, an estimation of Environmental Kuznets Curve for 62 municipalities in the state of Amazonas. The results point to the existence of an environmental CKA at Amazon with the presence of two spatial clusters. / O primeiro artigo desta Disserta??o procura sua inser??o nos debates e discuss?es que tratam de temas como pol?tica ambiental, desenvolvimento sustent?vel, desenvolvimento territorial e legisla??o florestal, dentro do contexto do desenvolvimento do Estado do Amazonas e, em especial, de um programa de desenvolvimento sustent?vel em execu??o no Estado, denominado Programa Bolsa Floresta (PBF). Embora tenha se iniciado h? poucos anos, seu perfil (remunera??o por servi?os ambientais) e sua abordagem territorial parecem dar-lhe um car?ter de inovador no que trata da pol?tica ambiental na regi?o. Mesmo muito insipiente, ele tem obtido bons resultados na resolu??o de problemas como o atendimento as popula??es tradicionais, resolu??o de conflitos territoriais e na gera??o de renda. No que tange o segundo artigo o mesmo trata das controv?rsias existentes entre o crescimento econ?mico, desenvolvimento sustent?vel e prote??o ambiental, levantadas a partir de trabalhos como de Grossman e Krueger (1995) que descrevem uma rela??o existente entre o PIB per capita e a degrada??o ambiental. Desta forma o presente artigo se prop?e a investigar esta rela??o a partir da identifica??o de padr?es espaciais da vari?vel desmatamento no Estado do Amazonas e assim de forma mais espec?fica investigar a influ?ncia da renda sobre o desmatamento, a partir de dois interesses principais (1) testar a exist?ncia da curva de Kuznets Ambiental, (2) mensurar a import?ncia do programa Bolsa Floresta. Para tanto, foi constru?do um modelo econom?trico com dados em Cross section para o ano de 2009, numa estima??o da Curva de Kuznets Ambiental para 62 munic?pios do Estado do Amazonas. Os resultados obtidos apontam para exist?ncia de uma CKA ambiental no Amazonas com presen?a de dois clusters espaciais.

The conflict between the pressing agricultural front, mainly represented by cattle and soya productions, and the preservation of such forest and cerrado areas, presents itself as a central theme in the debate over the sustainable development involving the studied area. This work presents an integrated analyses of the current land use and land cover dedicated to agriculture in one of the Amazonian micro-regions locally known as Microrregi?o Norte Araguaia, in the Midwestern Brazilian state of Mato Grosso. This study also includes other cartographic data sets that characterize such aspects as the related Legally Protected Areas and Priority Conservation Areas. The integrated analyses was done by way of geoprocessing techniques, with which the cartographic information data sets were crossed referenced in a georeferenced environment, i.e. spatially set and adjusted with a known coordinate system. The land use and land cover maps permit us to see changes related to the advancement of the agricultural frontier as well as to identify stands of the original vegetation. Thus, through an integrated analysis, this work offers a set of decisive factors to restrict the advance of the agricultural frontier and preserve the remaining tracts of original forest, within the Microrregi?o do Norte Araguaia. The main results identify potential areas of still standing patches of the original Amazon forest and cerrado vegetations to be conserved and that they make up a total of 4.1 million hectares of forests and cerrado land, within the agricultural expansion zone. Coincidently, more than half of these areas present poor or non-existing agriculturally apt soils. These cartographic products seek to spatially identify potential areas and establish the criteria for its occupation and use. / O avan?o da fronteira agr?cola sobre ?reas de floresta e cerrado na Amaz?nia Legal gera uma s?rie de impactos negativos ao meio ambiente tais como desmatamento e queimadas. O conflito entre o avan?o da fronteira agr?cola, traduzido pelo bin?mio gado-soja, e a preserva??o de ?reas de floresta e cerrado se estabelece como tema central no debate sobre desenvolvimento sustent?vel para a ?rea de estudo. Este trabalho apresenta uma an?lise integrada do uso e cobertura atual da terra com a aptid?o agr?cola dos solos na Microrregi?o do Norte Araguaia no Estado do Mato Grosso. Al?m dos planos de informa??es supracitados, foram inclu?dos nesta an?lise outros planos cartogr?ficos como ?reas Legalmente Protegidas e ?reas Priorit?rias para Conserva??o. A an?lise integrada ? realizada atrav?s de t?cnicas de geoprocessamento onde os planos de informa??es cartogr?ficas s?o cruzados em um ambiente georreferenciado, ou seja, localizados no espa?o atrav?s de um sistema de coordenadas conhecido. O mapa de uso de cobertura da terra permite verificar as ?reas alteradas pelo avan?o da fronteira agr?cola e identificar ?reas remanescentes de vegeta??o original. Assim, atrav?s da an?lise integrada se prop?em crit?rios para restringir o avan?o da fronteira agr?cola e preservar as ?reas remanescentes de vegeta??o na ?rea de estudo, a Microrregi?o do Norte Araguaia. Os resultados identificam ?reas que poderiam ser destinadas ? conserva??o da cobertura vegetal remanescente, que totalizam mais de 4,1 milh?es de hectares de florestas e cerrados em ?reas de expans?o da fronteira agr?cola. Coincidentemente, mais da metade destas ?reas apresentam solos com pouca ou nenhuma aptid?o agr?cola. O mapa final apresentado trata de identificar essas ?reas espacialmente e estabelecer crit?rios para sua ocupa??o.
