The cave environment has very peculiar atmospheric conditions that directly influence the existence and maintenance of biotic and abiotic, socioeconomic, and historical-cultural elements represented by or associated with caves. In caves where tourist activities occur, the human presence may affect the delicate balance of these conditions. This study was developed to characterize the cave microclimates of seven caves that are part of the tourist itinerary in the Parque Nacional Cavernas do Peruacu, located in the north of the state of Minas Gerais, Southeast Brazil. Temperature and relative humidity data were collected through 41 automated meters that each accumulated more than 110,300 readings. This research stands out for being one of the only long-term studies (2017 to 2019) developed in the country. The information analysis enabled not only characterization of the cave microclimate, but also observation of the relationship of these attributes with the internal morphology and the position of the caves in relation to the karstic relief of the region. The methodology developed in this study could support the Programa de Monitoramento das Condicoes Ambientais das Cavernas (Cave Environmental Conditions Surveillance Programme) to be implemented by the administration of the National Park, and identification of more sensitive environments in the interior of the caves will enable reordering of the visitation of these attractions.
Abstract: The discussion presented here is related to the territory and the economic activities. In this context, globalization has produced a new economy in which competitiveness needs information, knowledge, technologies, and the territory needs content that provides these elements. Study has focus on the Information Technologies (IT), which are important technologies for the formation of global world and for the changes in all areas of society. There is an effort to better define this activity, which is already born digital and makes time and space more flexible, building its geography. Thus, it seeks to locate IT activities and unveil the characteristics of this territory in which it is located. The analysis part is Rio Grande do Sul, and IT classification is based on the National Classification of Economic Activities-CNAE, and uses data from the Annual List of Social Information-RAIS and, with this, absolute data are obtained from companies and employees in the state. This study is based on quantitative data, in which information from national databases is used to structure conclusions, statistical softwares help the analyzes and the study is supported by cartographies, graphs and boards, elaborated by the study itself. As a result, we have geographical concentration of these activities, and the territories in which they are installed are loaded with science and technology, infrastructure and capital, that announces territorial inequalities and a hegemonization of processes in the world, in which the metropolises seem to be the winners.
Este artigo tem como objetivo geral compreender o processo de ocupação produtiva nas áreas de Cerrado pós 1960 e os impactos socioambientais imprimidos, a partir deste modelo de desenvolvimento, ao Estado de Goiás. Para isto, fazemos inicialmente uma caracterização geral do Bioma Cerrado, considerando sua diversidade biológica e o processo degradação sofridos historicamente. Em seguida analisamos o processo de modernização da agricultura e sua relação com o processo de degradação social e ambiental do Cerrado goiano e, por fim, buscamos compreender as características do movimento recente de fortalecimento do Agronegócio nas áreas de Cerrado, destacando o crescimento no uso de agrotóxicos, uma das bases deste processo. Metodologicamente, a construção do texto tem como base um levantamento referencial detalhado, a partir do qual, selecionamos alguns autores que entendemos ser essenciais para apoiar a compreensão e análise da ocupação histórica do Bioma Cerrado pela agricultura moderna. Os resultados demonstram, de forma geral, a nocividade do modelo baseado nos parâmetros no Agronegócio ao meio ambiente e para a sociedade de forma geral. O aumento no uso de agrotóxicos, especificamente, tem ocasionado impactos socioambientais irreversíveis ao Cerrado e à sua população.
