Diagnóstico antropogeomorfológico em bacia hidrográfica urbana: o caso do Córrego do Jardim São João, Araras (SP)

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

A importância da reserva legal para a preservação da fauna e flora existentes nas propriedades rurais de Botucatu

The main objective of this study was elaborating a diagnosis of technical conditions of Legal Reserves situation on the rural properties in Botucatu. In addition, considering the characteristics of fauna and flora and the economic aspects of these areas, it was presented alternatives to encourage the correct implantation and the effective preservation of the Legal Reserves. Because these areas contribute to the maintenance of local biodiversity and to availability of environmental services essential for all living creatures. In this study it was observed the presence of native vegetation in 13% of the rural properties’ areas in Botucatu, it is therefore necessary the recovery (reforestation) of 7% of all the rural properties’ areas, to be achieved the 20% of native vegetation (minimum area to be preserved as Legal Reserve, as disposed in Federal Law nº 12.651/12) on rural properties. A viable and significant alternative for recovery these areas, reinforced by the new forestry law, is the practice of sustainable management, that must be carried in harmony with conventional farming practices existing in the remaining areas of rural properties

Topobatimetria e geração de modelo digital de terreno no monitoramento da dinâmica fluvial do ribeirão Guaratinguetá

This research was developed with the goal of creating a Digital Terrain Model(DTM),through a topo-bathymetric data gathering that allows the monitoring of the fluvial dynamics of part of Guaratinguetá’s creek, where preliminary evaluations identified, in a short period of time, intense changes on its riverbed. Modern topography technics and tools were used for the data gathering, such as the use of geodesic GPS and Total Station. The DTM was primal for the project e execution of the desilting works of the researched part of the creek, being used to estimate the amount of soil to be moved. The comparison between the digital terrain models generated before and after the desilting has showed the efficiency and aplicability of this technique in the monitoring of the fluvial dynamics changes of Guaratinguetá’s creek

Energias alternativas: potencialidades para as regiões de maior demanda energética no Brasil

Since the beginning of life in society, the human being has sought sources of energy that can be used continuously, or stored to be consumed in times of need. The various energy generation processes has enabled the human race for the implementation of many activities ranging from food preparation, handling of large industries and even the possibility of total annihilation by the availability of powerful nuclear weapons. In Brazil, whereupon the various deleterious aspects and especially the finite resources used on a large scale for the energy conservation, there is a huge devotion of society referred to the prospects for alternatives to the use of energy in local, regional and global, but overall, as it wouldn’t be different, the main factors in this scenario are economic. The fact that the unused potential of a region in the use of alternative sources of energy leads to a larger socio-environmental prejudice generalized to all. The purpose of this project is targeted for a comprehensive, systemic and integrated discussion about some of the main alternative energy sources, associated with technical procedures related to them, to contribute to a better and effective use of natural resources available in each region of the country, in order to minimize the impacts on the environment in which they are inserted.

Diagnóstico dos riscos e impactos ambientais da suinocultura no Ribeirão dos Pinheirinhos, município de Torrinha, (SP)

The porcine activity is characterized by its great pollution capacity, generally produce loads of waste that usually are released in superficial water or soil without concern for the consequences to the environment. With this in mind, this study aimed to adjust the porcine production to the protection of water resources, in particular, Ribeirão dos Pinheirinhos in the town of Torrinha (SP), through inventory and diagnosis of the environmental impacts already present and environmental hazards linked to the activity in question. To achieve the proposed objectives, the productions of porcine on the studied area were raised and georeferenced, viewed and analyzed according to the technical and scientific literature. The production visited showed to be at odds with the protection of water resources due to lack of technical criteria in the development of treatment systems and waste handling, indiscriminate use of effluent and waste in the fertilization of crops and the lack of knowledge of producers on the influence of porcine waste into the environment. Based on these results, were set guidelines for action in the environmental awareness of farmers, to stimulate voluntary and conscious initiatives of environmental conservation in the direction of settlement of the activity.

Distribuição e abundância de Limnobium laevigatum na bacia hidrográfica do rio Itanhaém, São Paulo

A distribuição e a abundância das macrófitas aquáticas são determinadas por diversos fatores que limitam a ocorrência e o crescimento destes vegetais. Vários estudos sobre ecologia de macrófitas aquáticas têm sido realizados na bacia hidrográfica do Rio Itanhaém devido à grande abundância e riqueza de espécies de macrófitas aquáticas de água doce e salobra com diferentes formas de vida nos trechos de rios localizados na planície costeira, A macrófita aquática alvo deste estudo é a Limnobium laevigatum (Humb. & Bonpl. Ex Willd.) Heine que pode crescer enraizada nas margens dos rios ou flutuantes livres em locais com maior profundidade.Os objetivos deste trabalho são: (a) gerar um mapa de distribuição de L. laevigatum na planície costeira da bacia do rio Itanhaém; (b) verificar a existência de diferenças na abundância de L. laevigatum nos diferentes bancos desta espécie; (c) identificar quais são as variáveis abióticas responsáveis pela distribuição e a abundância de L. laevigatum na planície costeira. Para gerar o mapa de distribuição os principais rios da planície costeira foram percorridos em fevereiro de 2013 e em abril de 2015 e os locais de ocorrência foram georreferenciados. Nos locais de ocorrência foram coletadas amostras do vegetal para determinação da biomassa e teores de nitrogênio e fósforo na biomassa. Além disso foram feitas medidas de temperatura, pH, condutividade elétrica, oxigênio dissolvido e turbidez e coletas de água e sedimento para a determinação de nitrogênio e fósforo totais. Aos valores de biomassa foi aplicada uma Análise de Variância para verificar a existência de diferenças significativas entre os locais de ocorrência. Aos valores das variáveis abióticas foi aplicada uma Análise de Componentes Principais e aos dados bióticos uma Análise de Componentes Principais.
