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.

Análise do apoio dos sistemas de informação para as práticas de gestão ambiental em empresas com ISO 14001 - estudo de múltiplos casos

The purpose of this article is to identify the contributions of Information Systems (IS) for environmental management practices, as well as the opportunities and challenges in this relation. Thus, we performed two case studies with Brazilian enterprises certified ISO 14001, by conducting interviews, document analysis and direct observation. As results, we present the identification of the main contributions of information systems for environmental management practices in the studied cases, the verification that a more advanced stage regarding IS is a factor that implies a more effective contribution, besides finding challenges and opportunities in this relation. The main contribution of this research consists of the presentation of a framework that identifies the support of information systems for environmental practices.

Plano de recuperação de desastres: uma pesquisa-ação em empresa do setor energetico

This work has the purpose of demonstrating how to build a Disaster Recovery Plan. In order to achieve such objective, an adaptation of the PDCA method was applied. This plan aims resuming the IT operations as fast as possible after some kind of incident which result the stop of the services or activities. Besides serving as insurance for the continued functioning of the company’s activities, indeed your non-existence brings up risks of financial loss and threatens the company’s image. As to illustrate the functionality and validity, the method was applied in an IT department of an energy company. It was concluded that the plan was well elaborated living up to the purposes described in the objective section of this work and validating the project developed so far, having a percentage of 85% of the overall success of the systems tested

Recuperação de áreas degradadas através de sistemas agroflorestais: a experiência do Projeto Agrofloresta, sustento da vida

PETROBRAS started in 2003 the implantation of agroforestry systems as an alternative to recuperate degraded areas at Oiteirinhos Farm, of its property, located in the biggest terrestrial field of oil of Brazil, between the cities of Carmópolis and Japaratuba, at Sergipe. The project, idealized by the geologist Ismael Quirino Trindade Neto and called Agrofloresta, sustento da vida, has the model of agroforestry systems developed by Ernst Götsch as technical and theoretical references, which joins agricultural cultures with forest species. In this direction, it was evidenced that the practices adopted in the SAFs allow to join recovery, conservation and production, as it follows the biodiversity and the dynamics of the natural processes as basic principles of the practices adopted. Including social inclusion and economic return, the project expands the environmental aspect, turning into an action focused in sustainable development.

Sistemas de informação governamental para monitoramento e avaliação das políticas públicas: quadro de desafios e perspectivas de avanços

Governament organizations has as challenge for their governance the requirement ro improve evaluation system that measure the acting of their mediations and profefer for society informations about achievements. The text analyze the challenges and advances of evaluation tools for produce guidelines that could be inserted at context of decision-making from public agents. Thereunto informations must be reliable and real-time, creating vectors of haste for modernization of informational capacity of State as a whole.

Combinando sistemas de informação geográfica e redes neurais GMDH para prever densidades demográficas

The aim of this work is to advance a new approach for estimating demographic density, through combining a Geographic Information System with GMDH Neural Networks. The model that is suggested parts the analyzed space into a rectangular grid formed by multiple cells measuring 0.01 km2 each. The forecasts are elaborated based on the demographic density in each cell and in its neighboring cells at a given time. Despite the limited availability of data during the modeling phase, the utilization of this method for studying a Brazilian medium-sized city presented promising results.

Geotecnologia aplicada no estudo e planejamento de ocupação e uso do solo em uma bacia hidrográfica para fins agrícolas e conservacionistas

The study aimed to obtain the land use of the watershed Ribeirão Santo Antonio - São Manuel (SP), through the thematic map of the satellite image. The cartographic databases were planialtimetric letter in digital format used in georeferencing and the satellite image. Geographic Information Systems (GIS) -IDRISI Andes 15.0 was use to perform the image georeferencing and to do the thematic map obtained from the visual interpretation the satellite image. The map of land use showed that the culture of sugar cane occupies most of the area (81.00%), when analyzing the satellite image. This result show us the predominance of agricultural occupation in the region. The thematic map obtained by the classification screen, using GIS, allowed the mapping of land use, generating data that will assist in future planning area recovery. The results of the study showed the efficiency, speed and reliability of the tools used, these being very useful for future projects.
