Avaliação da Suscetibilidade a Movimentos de Massa no Município de Várzea Paulista (SP) Utilizando os Sistemas de Informação Geográfica

O objetivo deste trabalho foi identificar e mapear áreas suscetíveis a movimentos de massa, por meio das geotecnologias, no município de Várzea Paulista (SP). Para o propósito, foram utilizados os mapas de declividade, geológico, geomorfológico e de uso e ocupação da terra, que foram sobrepostos por meio da Análise Multicritério no SIG ArcGIS. Cada tema recebeu seu peso de influência para deflagração de tais processos e como resultado final foi obtido o mapa de suscetibilidade a movimentos de massa do município em questão. Paralelamente foi elaborado o estudo da orientação de vertentes, para determinação daquelas que apresentam maiores riscos em comparação com os dados coletados em campo. Constatou-se que existem muitas áreas ocupadas dentro do município que carecem de monitoramento do Poder Público, principalmente nos meses chuvosos, pois se encontram em locais frágeis do ponto de vista geológico-geomorfológico.

Desempenho agronômico de feijão‑caupi e milho semeados em faixas na safrinha

O objetivo deste trabalho foi avaliar o desempenho agronômico de cultivares de feijão‑caupi e de milho, em monocultivo e em cultivo consorciado em faixas, na safrinha. Foram realizados experimentos, em Dourados, MS (2009 e 2010), e em Botucatu, SP (2010). Utilizou-se o delineamento experimental de blocos ao acaso, com parcelas subdivididas e quatro repetições. As parcelas com feijão‑caupi foram constituídas por três sistemas de cultivo (em faixas com variedade ou híbrido de milho, além do cultivo solteiro) e as subparcelas, por três cultivares de feijão‑caupi (BRS Guariba, BRS Novaera e BRS Xiquexique). As parcelas com milho foram constituídas por duas cultivares de milho (variedade BR 473 e híbrido BRS 1030 ou BRS 1010), e as subparcelas, por quatro sistemas de cultivo (em faixas com as três cultivares de feijão‑caupi e solteiro). O sistema de consórcio em faixas consistiu de quatro fileiras de feijão‑caupi com quatro fileiras de milho. O consórcio proporcionou um uso mais eficiente da terra. As cultivares de feijão‑caupi apresentaram desempenho produtivo semelhante entre si, quando cultivadas em faixas com o milho. O híbrido de milho é mais produtivo que a variedade, tanto no cultivo solteiro quanto no consorciado.

Tipologia climática: subsídios para uma análise teórico-metodológica do clima na região metropolitana de São Paulo

The present study aims to establish the mapping units climate Metropolitan Region of São Paulo, with a more refined analysis in the study of extreme weather events to contribute to the adaptation of populations made vulnerable in the face of extreme weather events, and also as an aid local public policies, from a new perspective climate. As criteria of analysis, temperature, precipitation, altitude and use and occupation of land. For this we use as a work methodology broad literature review, fieldwork and use of geotechnology in the proposed mapping generation

Geotecnologias na avaliação da suscetibilidade a movimentos de massa no município de Várzea Paulista (SP)

The disordered occupation in several cities in Brazil, is very common, especially during the rainy season, there are numerous cases of gravitational mass movements, with deads of human and builds destruction. The main objective of this work was to identify and map areas to mass movements, through the geo, the municipality of Várzea Paulista, the state of Sao Paulo. For the purpose, were prepared thematic maps of slope, geology, pedology, geomorphology and land use and occupation, which were overlaid using ArcGIS GIS Multicriteria Analysis. Each subject received a weight of influence to the outbreak of such processes and the final result was obtained map of susceptibility to mass movements of the city of Várzea Paulista. This survey found that there are many occupied areas within the city that require monitoring of the Government, especially in the rainy months, because they are in very fragile in terms of geological and geomorphological features. Considering that the data on the physical and natural aspects are scarce in the literature for this region, the results obtained in this study as well as the gathering of information of the physical and cartographic products developed, will greatly contribute to the administration of the municipality, subsidies they provide for the proper use planning and land tenure, pointing out the weak areas of the city geotechnical point of view

Mapeamento geológico-geomorfológico na região de Quirinópolis-GO

Geological and geomorphological mapping is an important tool for the characterization of physical environment, thus enabling the planning and use of areas more efficiently. This work represents a geological- geomorphologic mapping on the scale of 1:20.000 in the rural area of Quirinópolis – GO town, where outcrop rocks of Paraná Sedimentary Basin, specifically the Bauru Group. Through the methodology of analysis of integrated elements of the physical environment, it was possible to delineate geological- geomorphological five units, which were characterized as lithology, topography, soil conditions, and operating processes, and the development of weathering profiles bring of great importance for planning of land use as occupation thus avoiding further degradation of the physical environment

Simulação de produção de sedimentos em microbacias em função de cenários de restauração florestal

In São Paulo state, deforestation and agriculture activities are increasing soil losses processes, especially in areas of susceptible soils where properties not adopt soil conservation practices. Environmental adequacy at property level regarding Permanent Protection Areas and Legal Reserves is considered a factor on reducing soil losses and considering that we assessed soil losses of different scenario of environmental adequacy. Simulations of erosive process were carried out in 15 catchments of Corumbataí river basin, according to different forest restoration scenarios, as well as the current situation of land use/land cover. The scenarios include the implementation of Permanent Preservation Areas (PPA), the reforestation of variable source areas, and two scenarios, the Legal Reserve installation in 20% of each catchment, being one of them for most critical areas in terms of erosion and the other at random. It was observed that the establishment of PPA and the reforestation of hydrologically sensitive areas, offered only a small contribution to the control of the erosive process, resulting in a reduction of 10% and 7,8%, respectively, while the legal reserve in critical areas has a significant reduction of 69,8%. The random scenario, in turn, resulted in a reduction of only 21,4%. Results show that reforestation could reduce soil losses, but previous studies of land prioritization and planning could increase significantly its efficiency at this process.

Análise da fragilidade natural do sítio urbano de Piracicaba (SP)

This research aims to analyze the natural fragility of Piracicaba Urban Site, through the analysis of a letter of Fragility Potential obtained through the data crossing the geomorphological cards, Pedologic Slope and use and occupation of the land to be developed during the project. The methodology to be used is that proposed by Ross (1990, 1994) together with the guided ideas Anthropogenic geomorphology, so that the man-made conditions of modification of the relief can be inserted in the final analyzes. The results showed that the Córrego do Enxofre Basin has high fragility of values, it is not a rich area for human occupation

Avaliação da adequação da ocupação do solo em áreas de preservação permanente (APPs)

Evaluation and adequacy of land occupation in Permanent Preservation Areas (PPAs) are important to ensure quantity and quality of water and local biodiversity. The objective of the study was mapping PPAs according to the Brazilian Forest Code and quantifying land cover and use, establishing the conflict of PPAs occupation in the Ribeirão Lavapés sub watershed. The area is 11,154.58 ha, and is located in Botucatu city, Midwestern region of São Paulo state. For this reason, geoprocessing tools, such as Remote Sensing and the Geographic Information System (SIG) were used. The dominant classes of land use and cover were the Urban Zone in Reverse Cuesta, 4,394.27 ha (39.39%) and Annual Crops in the Peripheral Depression, 3,670.89 ha (39.39%). The mapped area of native forest vegetal cover in the sub watershed was of 1,109.70 ha. Regarding the mapping of PPAs, considering the total area of 1,721.80 ha, a total of 532.15 ha (30.91%) are covered by Riparian Forest and 1,189.65 ha (69.09%) had no native riparian vegetation, therefore, requiring its reforestation.
