Um estudo sobre aspectos da gestão dos resíduos sólidos no município de Ribeirão Preto (SP)

Since the beginning of it’s existence the humankind coexists with the production of waste, both organics and inorganics. Over the years the world population is raising, and consequently the different kinds of waste, causing significant problems not only for the public authorities, but also for the population, not only those related with its final or temporary destination but also with its crescent production. Considering it, the cities are not able to handle there volumes, and its landfills and dumps are working over their capacities, leading to a serie of environmental problems due to the lost of environmental quality and the natural and social vulnerabilities arising. This paper plans to working over visits, photographic registration and a review on the theme literature, study the perception and valuation of the landscape on the Ribeirão Preto landfill, São Paulo state (SP), that today is disabled but still an area of risk and environmental vulnerability, well as the perception of environmental quality in the surrounding population

Zoneamento acústico urbano e mapeamento de níveis sonoros na zona central de Rio Claro (SP): diretrizes para o gerenciamento do ruído integrado ao planejamento ambiental urbano

Considering the growing degradation of the urban environmental quality resulting from the progressive sound pollution increase, as well as the consequent harmful effects about the human health, the present study had its central objective the argument and management tools implementation of the urban noise that can be integrated to the environmental planning in the city of Rio Claro (SP). Therefore, normative and bibliographical revisions were developed, that made feasible the directives of control argument and prevention of the urban noise, as well as the technical procedures of sound levels and evaluation’s definition and especially about the criteria applicable for the elaboration of an urban acoustic zoning methodology. Among the main results obtained detach: (1) the applicable legislation to the management of urban noise’s synthesis and argument; (2) the methodology of urban acoustic zoning development and (3) its implementation to determined areas of Rio Claro (SP) with the (4) respective cartography representation; (5) the mapping of sound levels in the central zone of Rio Claro (SP), (6) the obtaining and analysis of noise describers (LAeq, Lmáx, L10, L50, L90, Lmin and TNI) and the subsequent (7) acoustic maps elaboration for the main describers.

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.

Proposta de recuperação e manejo de nascente em área rural do município de Álvares Machado – SP

The lack of proper planning in intervention works of runoff water on rural properties and rural public roads leads to economic damage and loss of environmental quality. The impact of the action without technical base is soil erosion, siltation of water sources, loss of the quality and availability of water, invalidating areas for cultivation and livestock. The conservation of headwaters requires beyond regeneration of the environmental characteristics the repair and management of the degraded watercourse in order to control erosion. This graduate work in Environmental Engineering from Universidade Estadual Paulista Julio de Mesquita Filho - UNESP Presidente Prudente proposes a headwater recuperation and management in rural area of Álvares Machado municipality, São Paulo State, through the method of deep drainage applied to the case of a rural road near the outcrop of water. This technique consists in the installation of draining structures in sub-areas of the road surface, or sub-gutter and/or in the platform border in order to conduct the underground flow of water and reduce the loss of sediment in water flow. Therefore, was performed a historic study of use and occupation of land in the municipality of Álvares Machado, portraying transformations of the landscape caused by human action. Geology, geomorphology, pedology and hydrogeology data were collected from the study area in order to establish the conditions that led into the current situation of degradation and formulate an effective intervention strategy for civil works

Avaliação da degradação da mata ciliar no entorno do rio Corumbataí causada pela expansão urbana de Rio Claro/SP

In most brazilian cities, urban growth has occurred without adequate planning. Consequently, portions of the city were being occupied, often areas unfit for use and occupation of land, causing risks to local residents and decline of urban environmental quality. One of the most frequent problems is the riverbank occupation, causing the deforestation of the riparian vegetation. Given the above, this paper aimed to map the urban sprawl of Rio Claro/SP, as well as riparian vegetation in the vicinity of Corumbataí in the area including the urban area. For this purpose, GIS techniques were used in order to prepare the thematic map of urban expansion, as well as a map of the riparian vegetation through interpretation of aerial photographs in the environment of ARCGIS. From the maps, an analysis of “Plano Diretor” was made in order to verify if the current occupation of urban land meets the stipulations of this legal instrument

Análise comparativa de concepções de cartografia geomorfológica aplicada a ambientes litorâneos

The intense urbanization in coastal environments can cause environmental changes due to the susceptibility of these areas. It is therefore of utmost importance to understand the environmental quality of coastal area and the geomorphological features are essential to make it possible, as well as the geomorphological maps that are used as an instrument to analyze the relief. However, there is no standardization among the geomorphological mapping techniques, since the proposals vary according to the taxonomy of the relief, the adopted scale and the objective of the researcher. This paper aims to carry out geomorphological mappings of sectors of the city of Mongaguá, in São Paulo state, according to the conceptions of Verstappen and Zuidam (1975) and Gustavsson, Kolstrup and Seijmonsbergen (2006), seeking to verify the possibilities and constraints that each one can provide for environmental management. Verstappen and Zuidam’s design (1975) is a classical international bibliography proposal indicating the symbols and colors that will be used to represent the relief according to the origin shape of the geomorphological features; Gustavsson, Kolstrup and Seijmonsbergen's conception (2006) is a latest international proposal which also uses symbols and colors that can be combined to represent various forms of relief, coming from different origins. The mappings in this research are although not presented as a mainstream map, but as a cartographic representation in which the symbols are superimposed on the digital ortophoto map to provide the reader an association between symbolism and the relief represented. The result is a comparative analysis among the symbols that were used in each mapping, in which is discussed what design is the most appropriate, considering the adopted scale and the geomorphological features of the mapped area

Chuva, vulnerabilidade social e percepção do risco na cidade de São Paulo: impactos de eventos extremos nos bairros da Freguesia do Ó e do M’Boi Mirim

The city of São Paulo has, since the beginning of the expansion of its urban sprawl, represented relations of conflicts and contradictions between society and nature. Once the way society relates to nature is defined by how the social agents themselves correlate in certain social and historical contexts, the ways of interaction between the social and natural elements will be different according to the forms of production and appropriation of the urban space. Even more evident is the case of the great national metropolis, given its demographic dimensions and historical conditions, the process of urban expansion follows a logic where spaces of better quality for housing are occupied by those of better financial conditions. Thus, although there are exceptions, the poorest people live in places less desirable, in less resilient environments of lower environmental quality, relating to nature and its phenomena with greater risks. These risks are reflected here as recurring flooding, mudslides and landslides for which the rain is constantly blamed. So we have a situation where it is clear that a weather phenomenon differently interacts with different social groups. In this context, the study was conducted to compare extreme events occurred in two regions of São Paulo: the Freguesia do O, in the north side, and M'Boi Mirim, in the south side. Both are regions with large number of risk areas and are in the same urban climate unit. However, they present different conditions of social vulnerability. With the investigation of each extreme rain event occurred in the two regions, in the period of 2000-2010, supplemented by field research, we tried to observe how far the rain, with his intensity and volume, can, in fact, be related to the accidents.

Valoração do tratamento de efluentes de um curtume

During the production process of leather a lot of water is used. In addition, companies such as tanneries have high pollution potential. The effluent that is not properly treated , and it is irregularly released in water bodies can cause negative impacts to the environment and generate fines. The aim of this paper is to present the importance of environmental valuation in the effluent treatment system of a tannery, in order to add social and economic development with preservation of environmental quality. A valuation of inputs and outputs of the effluent treatment process from Tannery Bull in Presidente Prudente was made, as well as a proposal to improve the treatment and its valuation. Many of these industries do not account the costs from the effluent treatment and end up spending what could have been avoided. The management of environmental costs promotes sustainable development. Thus, we can conclude that, if there were better control and also an improved management of the tannery, the proposed treatment would bring economic improvement to the company and specially it would not cause much impact on the environment, including improving the quality of life in the region

Qualidade ambiental dos fragmentos florestais na Bacia Hidrográfica do Rio Jundiaí-Mirim entre 1972 e 2013

The location of Jundiai-Mirim river basin, close to large urban centers and industrial parks, has contributed to the appreciation of their lands. Consequently, the region has an intense process of urbanization that resulted in an increasing environmental disturbance in the forest areas. Given the need to preserve existing natural vegetation, because the watershed is the source of water used to supply Jundiai, SP, this study evaluated changes in the environmental quality of the watershed forest fragments between 1972 and 2013. The environment quality was determined by evaluating nine indicators of environmental disturbance, obtained by techniques of Geoprocessing and integrated by Multicriteria Analysis. The results showed a constant tendency of deteriorating the environmental quality of natural vegetation between 1972 and 2013, attributed to the intense process of occupation of the watershed. It is concluded that: (a) urbanization and deforestation of natural vegetation were primarily responsible for changes in environmental quality; (b) there is a need to create public policies to preserve the natural vegetation in the watershed.
