Expansão da cana-de-açúcar na bacia hidrográfica do Rio da Capivara (SP) entre 1977 e 2010

O sensoriamento remoto e o geoprocessamento com aplicação das técnicas de processamento digital de imagens são ferramentas fundamentais para a manutenção dos registros do uso do solo ao longo do tempo. Áreas do Vale do Paranapanema, no Planalto Ocidental Paulista, vêm nos últimos 30 anos aumentando seu polo sucroalcooleiro, por ser considerada uma das últimas grandes regiões do estado de São Paulo com solo, clima e relevo favorável para a expansão desta cultura. Entretanto, ainda não se tem um estudo pormenorizado sobre as mudanças no uso e na ocupação do solo na bacia do Rio da Capivara. Nesse contexto, esse estudo teve por objetivo avaliar, com o uso de sensoriamento remoto, a expansão do uso do solo com a cultura da cana-de-açúcar no curso médio da bacia do Rio da Capivara, sudoeste paulista, entre as décadas de 1970 e 2010. Para tanto, foram organizados mapas temáticos referentes aos tipos de solos e uso da terra da área, tendo sido usadas as ferramentas englobadas pelo SIG, sendo as cartas elaboradas com a utilização do software ArcMap 9.3. Os resultados mostraram que a cultura da cana-de-açúcar teve uma expansão de 31,24% na área da bacia do Rio da Capivara, passando de 4,32% em 1977 para 35,56% em 2010. Essa expansão ocorreu principalmente sobre áreas antes utilizadas com pastagens, mas também pode ter ocorrido sobre áreas de remanescentes florestais

CONSIDERATION ABOUT A CONSERVACIONIST STUDY ABOUT THE MICRO BASINS HYDROGRAPHICS OF THE RIVERS DOS APERTADOS AND TRÊS BOCAS, NORTH OF PARANÁ – BRAZIL

The environmental planning in hydrographic micro basins may minimize the incidence of environmental impacts as consequence of the human indiscriminate action. The hydrographic basin is worldly recognized as the best unit for handling natural resources. Thus, a methodology for diagnosis of the real situation of natural resources, in a basin, turns to be a necessary tool for the preservation and management of these resources. The identification of the different kinds of predominant vegetables informs, chiefly, about the level of soil protection, since the vegetation is responsible for the protection against the impacts of the raindrops (splash), by the reduction of the speed of surface outflow (runoff), through the increasing of the land ruggedness and greater soil structure constitution that may offer greater resistance to the action of the erosive processes. Besides, the collected data about the covering vegetation generally comes along with the information about the current use of the soil, since they both are strictly related. Several authors have pointed out the importance of geo morphological mappings of environmental planning projects. The use of the cartography and geo morphological information aim to represent the physiography of the landscape,considering the elements identification or environment of transport and accumulation, characterization of the morph genetics processes, and the human action implications. From the environmental point of view, the landforms are factors that influence the local hydrological conditions and specific top climatic. In this sense, the micro basins of Ribeirões dos Apertados and Três Bocas located between the municipalities of Londrina and Arapongas, North of Paraná, though constituted by fertile soils, Nitossolos and Argissolos, present a mainframe of environmental degradation common to other micro basins of the region, or, the lack of banks vegetation, the action of erosive processes, blocking the water fountains, and turning unviable the maintenance and increasing of the productivity of these areas. This study aims the composition of an environmental diagnosis of a limited area between two micro basins, as well as to evaluate the system of handling the soil and the effectiveness of conservationists’ practices that have been used in order to present an environmental planning.It can be observed that in some agricultural areas, at least in the beginning, between two micro basins, some conservationists practices were used as handling and use of rural soil, the build of terraces, recovering of dirty roads, and suitable handling of the agricultural defensive packing, among others. But what is really outstanding in the properties, like everything else in Paraná state, is the introduction of The Direct Planting System. The results of these actions mainly when working together with the responsible organs of agricultural management, are effective in the improvement of environmental conditions for the agricultural development activity, rather with the increasing in production and maintenance of the environmental balance in the micro basins. It was noticed also that in many rural properties of the studied area, are beginning to adopt the direct planting system. However, it is necessary to guide the human occupation in order to keep safe the areas intended to be of environmental preservation, aiming the conservation of the natural resources, the strong environmental fragility and high susceptibility to erosion of this area of study

Soil aggregation and carbon stabilization in burn and no-burn sugarcane management systems

ABSTRACT Retaining sugarcane straw over the soil after harvesting can improve soil structure and increase soil carbon stabilization, mainly in macroaggregates. We evaluated the carbon content in the aggregate classes in areas under burn and no-burn (adopted for five years) sugarcane management systems, focusing on the superficial layer (0.00-0.20 m). The experiment was carried in an Oxisol and the treatments consisted in burnt sugarcane, manual harvest; burnt sugarcane, mechanized harvest; and no-burn, mechanized harvest. The retention of sugarcane straw on the soil surface is justified by the increase in carbon content and carbon stock in the surface layer (0.00-0.20 m) by restructuring of the soil, even though it cannot match the structure of the soil under native forest. Our results suggest that in no-burn management the carbon not occluded inside aggregates was important to increase carbon stabilization in soil and that more attention should be given to macroaggregates 2.00-8.00 mm present in this management system, that showed higher carbon content and was responsible for increase of the geometric and weight diameter, increasing the erosion resistance in the long term in relation to burn systems

Neoplasia intra-epitelial grau III da vulva e da região perianal tratada com vulvectomia superficial: relato de caso High-grade vulvar and perianal intraepithelial neoplasia treated with skinning vulvectomy: a case report

A neoplasia intra-epitelial vulvar grau III (NIV III) se manifesta de modo visível, portanto, acessível à biópsia e, por conseguinte, ao diagnóstico histológico. Há duas formas precursoras do câncer vulvar: a NIV associada ao papiloma vírus humano (HPV) e a NIV associada ao líquen simples crônico, hiperplasia de células escamosas e líquen escleroso, não tratados. Porém, pode existir sobreposição das duas formas. O termo papulose bowenóide, apesar de ser desencorajado, define uma das formas clínicas da NIV, que se apresenta como lesões pigmentadas, verruciformes, papulares e múltiplas. A NIV III está associada com HPV em mais de 80% dos casos e em 40% das vezes, nota-se envolvimento perianal. O seu tratamento é muito difícil e pode ocorrer recorrência em qualquer tempo e por muitos anos. Embora não exista tratamento padrão definido, os trabalhos apontam para a cirurgia, respeitando margem de segurança, como o mais adequado.<br>High-grade vulvar intraepithelial neoplasia (VIN III) is a visible lesion; therefore, it is accessible to biopsy and thus, to a histological diagnosis. There are two forms of vulvar cancer precursors: VIN caused by human papillomavirus (HPV) and VIN associated with untreated lichen simplex chronicus, squamous cell hyperplasia, and lichen sclerosus. There may be overlap of the two forms. The term bowenoid papulosis, although discouraged, identifics a clinical form of VIN III. Such lesion appears as pigmented, wart-like growths or papules. VIN III is associated with HPV in more than 80% of the cases, and there is perianal involvement in 40% of the times. Vulvar intraepithelial neoplasia is difficult to cure and relapses can occur at any time for many years. Although there is no defined standard treatment, studies point to surgery, respecting a free margin, as the most adequate one

Physical properties of a rhodic haplustox under two sugarcane harvesting systems

This study had the purpose of evaluating the effects of two management types of sugarcane: harvesting of burnt cane (BCH) and mechanized harvesting of unburnt green cane (MCH), on some soil physical properties of a dystrophic Rhodic Haplustox. The data were then compared with results for the same soil type under native forest. A completely randomized design was used, with three treatments and 20 replications. The following characteristics were determined: organic matter, aggregate stability, soil bulk density, and porosity at depths of 0-0.20 m and soil penetration resistance. After 15 years of cultivation, there were some alterations in the soil under cane burnt before harvesting, evidenced by a drop in the weighted average diameter of stable aggregates in water and increased soil bulk density. Significant changes were also detected in total porosity and pore distribution under both harvesting systems. Critical values for penetration resistance were observed in the area under mechanized sugar cane harvesting, with a value of 4.5 MPa in the 40-55 cm layer. This value is considered high and could indicate compaction and restriction of root growth. Soil properties under the green cane (unburned) management system were closest to those of the soil under native forest
