Diagnóstico ambiental das áreas de expansão urbana do município de Jaguariúna - SP

The spatial chaotic urban growth is an increasing and common problem in Brazilian cities, especially in the State of São Paulo. In order to assist the territorial expansion planning, the present study aimed to conduct the environmental diagnosis of urban expansion areas in the City of Jaguariúna – SP, bounded by the Municipal Plan. From the preparation and analysis of thematic maps, literature review and field analysis, data were collected for use and occupation, geology, geomorphology, pedology, vegetation, water resources and features surrounding the five urban sprawl existing areas. It was noted, in general, that these areas are suitable for urban occupation, since they show flat geomorphology characteristics, with flattened, medium to large hills, slightly undulated, with low slope, and soils that do not present risks to the deployment of buildings, once properly managed. It was also observed a few water bodies crossing these areas and a few areas with native vegetation beyond permanent protection areas along the rivers. By the analysis of these areas and their surroundings, it was possible to determine on which area the urbanization process can occur more quickly. Thus, the study allows the City of Jaguariúna to perform a more effective occupation planning in these areas, always aiming the sustainable development and, consequently, the improvement in population’s quality of life, as well as the maintenance of environmental quality.

Avaliação de língua portuguesa em provas escolares do século XX (1935 e 1963)

The article analyses three school exams of Elementary School, two belonging to a mother and one of her son, which were kept and provided to the researcher by the mother. The first two exams were dated March 30 and November 13, 1935 of the 3rd grade of Grupo Escolar Fernando Lobo in Juiz de Fora, Minas Gerais. The third one was produced at Grupo Escolar Coronel Amâncio Bueno in Jaguariúna, São Paulo in March 28, 1963 in a 4th grade class. The analysed data all together point out school products which are the result of the relationship between teacher, student and school culture. School exams are as important documents as the notebooks in order to understand the school culture, and as this paper tries to indicate, they are the means for the insertion into the world of written culture. The methodology based on the microanalysis of these documents reveals records about the structure of the exams and the Brazilian school curriculum in the teaching of Portuguese as a mother tongue in 1935 e 1963.

Avaliação do desempenho ambiental da produção canavieira com colheita mecanizada: contribuição à implantação de um sistema simplificado de gestão ambiental da propriedade

The consuming of the natural resources in the agricultural sector does not represent only one external factor of the productive process, but also it implies in a bigger cost for the production, justified for this environmental degradation. In view of the necessity of evaluating the sustainment of the agricultural businesses, the use of performance indicators if makes of extreme importance. The measurement of the support through environmentalindicators is one of the most accepted forms of performing the evaluation of one given agricultural activity. In this context, the Base System for Eco-certification of Agricultural Businesses (Eco-cert Rural) developed by the Embrapa Environment at Jaguariúna/SP, has for purpose to present a method of evaluation of the agricultural businesses, not only of the point of view of the ecological performance, as well as considering the social, economic and organizational aspects. Through the analysis of the performance of the activity and the regularization of the disconformities found, it makes possible the eco-certification of the activities in the varied existing protocols, offering technologies designed to the sustainable development of the agricultural businesses. Using Eco-cert.Rural, this work evaluated the contribution of the use of mechanized harvest in sugar cane handling, front to the traditional system of manual harvest, using the fire. In the Sugar Cane Activity General Performance Index, Agrícola Rio Claro scored 2,08 of a maximum of 15. Amongst all the indicators, those wich reached performance worse had been related to the Use of Energy and the Income, by increasing fossil fuel consumptiom, and implying income concentration due to resignations of rural workers. However, the improvements on the environment quality by supressing manual harvest through fire are very significant. Beyond the great reduction in...(Complete abstract click electronic access below)

Monitoramento participativo de sistemas de produção orgânica através de indicadores de sustentabilidade

O século passado foi marcado por grandes avanços tecnológicos na agricultura que culminaram com a chamada “Revolução Verde”, a qual é hoje, comprovadamente, considerada como um modelo insustentável. Tal fato tem motivado instituições científicas e agricultores a buscarem por novos paradigmas para a produção. A agroecologia tem se destacado por abordar o manejo de agroecossistemas dentro de uma visão holística, sistêmica e participativa, subsidiando a recuperação das suas funções e a autonomia durante a transição agroecológica. Nesse contexto, a utilização de ferramentas para avaliação e monitoramento do processo, como a análise de indicadores de sustentabilidade, é fundamental. O presente estudo teve como objetivo monitorar participativamente o grau de sustentabilidade de duas unidades de produção orgânica em Jaguariúna-SP, após cinco anos de uma primeira avaliação. Foram analisados 81 indicadores, abordando quatro dimensões da sustentabilidade: ambiental, social, econômica e política. Os resultados foram obtidos de forma consensual e participativa entre pesquisadores e agricultores, enriquecendo o estudo. Do ponto de vista global, houve um leve avanço no grau de sustentabilidade das duas propriedades. No entanto, ambas continuam no mesmo nível de transição agroecológica apresentado em pesquisa realizada em 2005.
