Mapeamento do uso da terra como subsídio a um plano de recuperação das áreas de preservação permanente no entorno da represa de Salto Grande - Americana - SP

Currently, the dam of Salto Grande is very degraded. Water quality is seriously amended, and lack of riparian vegetation, as well as the advance of feed crops and land occupation in areas that should be permanently preserved, only complicate this situation. The permanent preservation area is essential for the water sources protection, soil erosion control and consequent watercourse sedimentation. Through aerial photography, using GIS techniques, it was able to identify the outwards bounds of the dam, to demarcate the permanent preservation areas and generate maps for land use. With this data, in addition to studies and ideas of reforestation in different environments, the development of a plan for restoration of degraded areas surrounding the dam is easier to be done. This study confirmed that about 72% of land use in permanent preservation areas is not in accordance with specific laws, making necessary its recovering.

População e áreas de risco: o caso das inundações na área central de São José do Rio Preto-SP

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

Ocorrência de evento climático extremo na cidade de Rio Claro-SP: episódio 24 e 25 de fevereiro de 2010

This work focuses on the analysis of extreme precipitation episode in the city of Rio Claro, held on 24 and 25 February 2010, which caused severe impacts to society, and a victim of drowning due to flooding due to flood in urban stream. Although the temporal concentration of summer rainfall is characteristic of tropical climatic regimes, each year there are issues of social and environmental impacts deflagrated by precipitation events in the city. These findings reinforce the importance of analyzing atmospheric conditions correlated to change in space usage

Efeitos da ocupação e uso da terra na bacia do córrego da Servidão, no cenário de 1995-2006

Urban sprawl developed without adequate urban planning and lack of knowledge about the physical characteristics of an environmental system, results in soil sealing and consequent change in the dynamics of hydrological watershed. Thus, this study aimed to analyze the behavior of the runoff basin Cóorego DA Servidão located in Rio Claro, referring to the year of 1995 compared to the scenario of 2006, compared the different features of urban use logged area. Therefore understanding the dynamics of the flow was possible through the use of software IPHS 1 that allowed through hydrologic models to evaluate the behavior of the surface area investigated, using Spring 4.3.3 software which enabled the classification of land use and software ArcGis 9.3 which was used for the quantification of stretches of water, separated from those that are channeled and those who did not suffer interference from the pipe

Patrimônio natural e cultural em uma área de expansão urbana: o caso da Granja Carolina - Cotia/Itapevi - SP

El objectivo del trabajo fue analisar los impactos ambientales y sociales de las politicas publicas y de la especulación imobiliária sobre las áreas remanescientes de la vegetación nativa en la Granja Carolina. Con base en la definición del Património Cultural y Património Natural, fue abordado el proceso de formación desa región oeste de la metrópole, especificamente en lo entorno de la Granja Carolina situada entre los municipios de Cotia y Itapevi. La identificación deses problemas y la realización de un estudio sobre el modelo de la ocupación y el uso de lo solo urbano permitiu identificar su grau de vulnerabilidad a los impactos traydos por la expansión urbana. Para lo entendimiento de tais cuestiones analisamos lo proyecto y lo EIA/RIMA de um empreendimiento imobiliario que si pretendia instalar em la área de estúdio. Entendese también que el planejamiento territorial debe conter el debate sobre la protección del Património Cultural y Natural, cuestiones también pertinentes em el campo de la Geografía

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Análise das alterações temporais dos fragmentos de vegetação no centro experimental do Instituto Agronômico, Campinas, utilizando técnicas de sensoriamento remoto e geoprocessamento

O presente estudo tem como objetivo principal realizar um levantamento temporal das áreas de vegetação no Centro Experimental de Campinas (CEC), uma fazenda de propriedade do Instituto Agronômico (IAC), a partir de técnicas de geoprocessamento e fotointerpretação. O local de estudo situa-se no município de Campinas - SP, e a área em questão foi escolhida por estar situada dentro de uma propriedade do estado e por apresentar uma grande mudança histórica no que diz respeito à vegetação. Também por que, apesar de ser um centro de experimentação agrícola, esse estudo demonstrara como num intervalo de quarenta anos a consciência ecológica muda radicalmente dentro do Centro. Para a realização deste trabalho, foram utilizadas fotografias aéreas digitais da fazenda dos vôos referentes aos anos de 1964, 1972 e 2002, todas de propriedade do acervo do Laboratório de Geoprocessamento do Centro de Conservação dos Solos do IAC. Alem da foto de satélite da fazenda obtida no software Google Earth, com data de 2006. Analisando imagens e mapas, observou-se como a área vegetada aumentou no Centro Experimental de Campinas nesse intervalo de quarenta e dois anos, passando de 7,55% (52.383 ha) em 1964 para 34,13% (236,497 ha) da área total do centro em 2006. Também pode-se ver que hoje há uma preocupação muito grande com a manutenção e conservação dessas matas.

Caracterização de impactos socioambientais no setor sucroalcooleiro: o caso da fuligem em Piracicaba - SP

A busca por novas fontes de energia é consequência do aumento da demanda de energia consumida no mundo. Com a instabilidade política dos países detentores das maiores reservas de combustíveis fósseis e a eminência do esgotamento dos recursos naturais surge a preocupação de produzir uma energia mais limpa, desta forma, surgem os estudos com a biomassa, no caso, a cana de açúcar. Esta pesquisa tem como objetivo entender as relações do cultivo cana e da produção de etanol, caracterizando seus impactos socioambientais. Além disso, procura demonstrar a manifestação de um dos efeitos negativos gerados na fase agrícola. A prática da queima da cana é muito antiga, porém ainda muito utilizada. Esta gera efeitos diretos na saúde do trabalhador e da população, neste sentido, procuramos saber se a população está ciente desta prática e das suas implicações. Portanto, esta pesquisa justifica-se para colaborar com os estudos ligados a produção de energias mais limpas, para alcançar o desenvolvimento sustentável

Análise de uso da terra e sua interferência em enchentes na região do Córrego Lavapés, Rio Claro (SP)

The development of cities is initially nearby rivers and with the intensification of the urbanization process occurs the soil sealing, leading to an increased level of water runoff, and, consequently, in a greater number of floods. The main goal of this study is to verify the interference of land occupation in the floods of the Lavapés Stream basin, Rio Claro (SP), in five temporal series, 1962, 1972, 1988, 1995 and 2014. The characterizations of land use were made from photo-interpretation and, thus, were produced thematic maps on scale 1: 20.000. The description of the Soil Conservation Service, 2007 was the basis for the classification of land use, thus achieving the CN parameter (Curve Number) used in hydrologic modeling done in IPHS1 program. The results indicate that soil sealing associated with the growth of the city of Rio Claro are responsible for increasing of the discharge in the Lavapés Stream basin and floods in this watershed

As políticas públicas ambientais e a dinâmica do espaço rural no município de Araras (SP)

Historically the evolution of the occupation of ararense territory was due to the expansion of agricultural activities. Such activities were intensified with the transformations engendered by the Green Revolution, increasing the exploitation, the area occupied by agriculture and the deforestation and consequent environmental degradation. Therefore the current reality of rural areas in Araras/SP has shown that part of agricultural practices made it does not guarantee the effectiveness of environmental legislation and the sustainability of farms. Considering the recently implemented environmental policies, such as Law nº 12.651 / 2012, better known as New Forest Code and Decree nº 8.235 / 2014 establishing a period of one year to rural property registered with the Rural Environmental Registry (CAR), as tools targeting to reduce environmental degradation and contribute to building a sustainable rural development. This work aims to analyze the dynamics of the rural municipality of Araras on the environmental situation in some rural properties and actions to be taken by the owners to the full compliance of its properties before the environmental public policy
