A estrutura do comércio bilateral entre o Brasil e a República Popular da China - China alterou-se ao longo das décadas de 1990 e 2000 e dos anos 2010 e 2011, que correspondem ao período de análise. Os indicadores monetários e físicos aqui utilizados sugerem que essa relação bilateral de comércio apresenta impacto negativo sobre o meio ambiente e uma tendência exponencial deste impacto. Os indicadores físicos parecem permitir uma extrapolação maior do que os monetários: apesar da China estar contribuindo com uma parcela maior com as mudanças climáticas - maior valor absoluto de emissão de CO2 das exportações -, o Brasil está contribuindo proporcionalmente mais do que aquele país para a insustentabilidade global. Assim, a dinâmica dessa estrutura aponta para aumento da vulnerabilidade do setor exportador brasileiro, tanto no aspecto ambiental como no tecnológico, fator primordial para minimização do impacto sobre o ecossistema local e global

The present study sought to develop a methodology to analyze the water quality based on concepts and methods of climate and climatology respectively. In this way, it was tried to relate techniques and methodologies hydro and limno-meteorological with a rhythmic analysis technique developed within the Brazilian geographical climatology to assess and analyze the blooms of cyanobacteria, the main index of water quality found in reservoirs of “Alto Tietê” Basin and consequently the Metropolitan Region of São Paulo, an area of high environmental complexity due to its high degree of development and high population density. The meteorological data used to develop the study were collected from the meteorological station of the IAG / USP and the limnological data were collected from the Hydrological Monitoring System implemented by SABESP in Billings and Guarapiranga reservoirs as well as data laboratory of the same entity. The results obtained by the rhythmic and integrated analyze showed that the process of blooms of cyanobacteria is dependent not only on one specific factor, but a combination of meteorological factors that may disrupt the stability of reservoir and which can, during the stabilization process, provides the necessary conditions to the development of cyanobacteria. It was also shown by the results that the pace of Atlantic Polar Front Entrance during the winter in São Paulo, is a limiting factor to the growth of cyanobacteria due to their high frequency, keeping the reservoir balance throughout the period. Furthermore, another importance of this study is the possibility of prevention and forecasting periods which are inappropriate for the use of these reservoirs mainly for recreational activities

A questão agrária é da essência do modo capitalista de produção. A existência ou não do campesinato nesse modo de produção é justamente o cerne da discussão. A questão agrária pode ser interpretada de diferentes formas, por meio de correntes teóricas ou até mesmo paradigmas, como o caso do Paradigma da questão Agrária e o Paradigma do Capitalismo Agrário. Neste trabalho procuro defender a ideia de que a questão agrária é um problema estrutural do capitalismo, atualizada conjunturalmente por diferentes elementos, sejam eles de cunho social, político ou econômico. Um destes elementos, destacado nesta pesquisa, é justamente a luta pela terra em escala nacional e regional. A criação e recriação do campesinato no Brasil tem se dado, principalmente, a partir da luta pela terra, materializada em ocupações, acampamentos e, conseqüente, criação de assentamentos rurais. Em escala nacional, discuto a diminuição das ocupações de terra e de novos acampamentos nos últimos anos, com o intuito de compreender as possíveis causas. Já, em escala regional, no Pontal do Paranapanema-SP, algumas mudanças no que diz respeito à mobilização das famílias semterra e a esporacidade da vida nos acampamentos são apresentadas a fim de colaborar com a discussão sobre a dinâmica, contemporaneidade e perspectiva da luta pela terra

The assessment of land use dynamic can be an instrument for analysis in anthropogeomorphology, which would allow one to verify the human geomorphological actions and its various implications in changing the original morphology for the creation of a human morphology. This study aimed to consider the land use dynamics and its interference in the morphology of Cavalheiro Stream Basin. From this assessment, to understand the implications of land use in the creation of a human morphology, as well as to analyze if the current use is in accordance with the legal restrictions placed by ongoing environmental legislation and with the ability to land use. The chosen of this studied area was due to assumptions raised by Pinton (2007) for changes in the dynamic of rainwater erosion of this area caused by human actions, specially the cultivation of sugar cane in morphologies that are unfit for it. The search took as methodological support the principles that concern the General Systems Theory, trying to see the watershed as an open system. The geomorphological data, of land use and of legal restrictions to the use and occupation of land, were collected from different cartographic techniques. Besides, it was developed a sketch map of land use capacity by adapting the technique proposed by Lepsch (1983). This way, the data obtained in this survey are considered capable to provide subsidies for the identification of changes in original morphology of the Cavalheiro Stream Basin and the genesis of a human morphology, as well as conflicts and adjustments of current land use in environmental system and on the legal restrictions outlined in the ongoing environmental legislation, contributing to a proper environmental planning with the characteristics of the physical environmental system of this basin

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

This monograph object of analysis is the agriculture modernization in Brazil between 1960 and 1980, highlighting the discussion of the economic and politic ideas around the Brazilian agrarian question. The first parte presents an introduction about this issue and the theoretical positions, as well as social and economic implications for the development of the productive forces on rural areas. Nevertheless, reflections of its development to the economy as a whole, highlighting the way the income distribution and concentration was realized. On the second part its presented the agriculture modernization Project on the centralized militar government point of view, by the propositions of that time Agriculture Minister, Antônio Delfim Netto. The approach is made through the proposals precreeded by the Rural Worker Statute and the Land Statute, before the Military Coup, with its news counterpoints settled in law by the Agriculture Modernization Project installed in 1964; the concessions of funding grants and subsidized credits; the relationship between the authoritarian State and the militarization of the land conflicts. The third part deals with the salary dinamics, income and profit on the modernized rural economy created by the agroindustrial productions system. Lastly the conclusion cross the economic and social results of the agrarian question evolution, to the Brazilian agriculture modernization on income distribution

Este trabalho teve como objetivo principal analisar a dinâmica geomorfológica, bem como a apropriação humana do relevo, mediante a interpretação de forma integrada dos documentos cartográficos elaborados a partir de técnicas da cartografia morfométrica, geomorfológica e de uso da terra, de forma a subsidiar ações vinculadas ao planejamento ambiental da Bacia do Ribeirão Tijuco Preto (SP). Sob os auspícios da abordagem sistêmica, a partir de uma visão integrada e complexa dos sistemas geomorfológicos, propôs-se a quantificar os atributos das formas de relevo, representando-os cartográficamente com a elaboração das Cartas Morfométricas de Declividade ou Clinográfica (De Biase, 1970 e 1992), de Dissecação Horizontal (Spiridonov, 1981 e adaptações de Mauro et. al.,1991), de Dissecação Vertical (Spiridonov, 1981) e de Energia do Relevo (Mendes, 1993). Também, contemplou-se a cartografia geomorfológica de detalhe, com a elaboração da Carta Geomorfológica (Tricart, 1965), bem como o mapeamento do uso da terra, expresso na Carta de Uso da Terra (Ceron e Diniz, 1966). De forma geral, a análise dos Produtos Cartográficos elaborados, permitiu constatar que a Bacia do Ribeirão Tijuco Preto vem sofrendo o desencadeamento de processos erosivos variados. Tais processos estão associados a uma conjunção de condicionantes, que podem ser apontados pelas variadas condições morfométricas do terreno, o clima quente e úmido reinante, as diferentes litologias aflorantes, a tipologia dos solos, bem como, e, de maneira veemente, a intervenção humana. O condicionante antrópico está majoritariamente representado pela monocultura canavieira e pela urbanização, sendo agentes cruciais no desencadeamento dos processos erosivos existentes e na interferência direta na dinâmica do escoamento fluvial da Bacia do Ribeirão Tijuco Preto.

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost

Currently the forests around the world face different aspects of weather. Global climate change and its adversities alter significantly the dynamics of the forest, directly influencing the operation. Human activities interfere in the functions of forests, either by removal of vegetation, either by reforesting deforested areas. Given the influence of human activity and climate change on forests, this project presents a comparative and analytical situation, the microclimatic level, the State Forest Edmundo Navarro de Andrade (FEENA), in Rio Claro. We measured the temperature maximum, minimum and average in different periods surrounding the FEENA, from 1889 to 1917, 1971 to 1999 and from 1999 to 2011. What allowed to suggest changes in the microclimate of your surroundings and probably in forest dynamics

A coruja-buraqueira (Athene cunicularia) nidififica no chão e, com frequência, ocorre em ambientes bastante urbanizados como no campus universitário da UNESP em Botucatu, SP região centro-oeste paulista. Os objetivos do estudo foram descrever as características físicas das escavações, distribuição espacial, formas de utilização e avaliar que elementos presentes nas áreas urbanas são importantes para a seleção dos sítios de nidificação. Foram monitorados 6 grupos familiares desde 2011, cuja população e o número de ninhos foram contabilizados e a localização, georeferenciados. Os dados comportamentais foram registrados em caderno de campo, fotografados e filmados. A densidade populacional no câmpus foi de 0,03 indivíduos por Km² com os sítios de nidificação vizinhos tendo a distância mínima de 140,0 metros e máxima de 378 metros. As tocas apresentaram 50,6± 5,6cm de diâmetro, a maioria construída em terreno com declive. As corujas selecionaram sítios de nidificação em áreas abertas e gramadas contendo no entorno poleiros naturais (árvores, arvoretas, arbustos) e artificiais (placas, postes, peitoral de janelas, etc) e próximos a bueiros e postes com iluminação artificial. Estes dois últimos constituíram atrativos paras as suas presas (artrópodes e roedores) e a análise de ergagrópilas revelou a ocorrência de 5 grupos taxonômicos de artrópodes: 65,4% de Coleóptera, 27,2% de Orthoptera, 4,6% de Blatodea, 1,4% de Aranae, 0,9% de Hymenoptra e 0,4% de Mantodea. Os resultados obtidos mostraram que as corujas-buraqueiras levaram em consideração características como oferta abundante de alimento, principalmente, de artrópodes que se concentravam nas área iluminadas e nos bueiros. A estabilidade temporal dos sítios de nidificação nestes três anos de monitoramento acompanhada de sucesso reprodutivo de 50% revela que a despeito do intenso tráfego de veículos e transeuntes no campus, o ambiente ...
