Composição florística e estrutura fitossociológica em área de regeneração natural de cerrado na Floresta Estadual Edmundo Navarro de Andrade, Rio Claro, SP

O Estado de São Paulo apresenta poucos remanescentes de vegetação nativa, ameaçados pela expansão urbana e agricultura. Com a grande expansão das atividades silviculturais no país, estudos sobre as contribuições e impactos das florestas plantadas são de grande importância na análise da sucessão secundária e conservação de ambientes naturais. O trabalho teve como objetivo a análise da composição florística e estrutura fitossiológica do estrato arbustivoarbóreo de uma comunidade vegetal regenerante na face norte dos talhões 91G, 91H e 91I, na Floresta Estadual “Edmundo Navarro de Andrade” (FEENA), em Rio Claro, SP, em uma área anteriormente ocupada por Eucalyptus sp, sendo as espécies classificadas quanto as classes sucessionais e síndromes de dispersão. A área correspondente aos talhões 91G, 91H e 91I está incluída no Plano de Manejo como Zona de Recuperação, para posterior inclusão no zoneamento como área permanente. Foram alocadas 28 parcelas com dimensões de 20x10 metros cada, totalizando 0,56 ha amostrados. Os resultados indicaram a presença de 79 espécies pertencentes a 34 famílias, sendo as famílias Fabaceae, Asteraceae, Euphorbiaceae e Myrtaceae as mais representativas em número de espécies. Houve grande abundância e dominância de Virola sebifera e Siparuna guianensis, amplamente distribuídas na área. A maior parte das espécies amostradas é pioneira ou secundária inicial, sendo a grande maioria zoocórica, o que sugere presença de fauna. Foram encontradas muitas espécies generalistas, algumas típicas de floresta e cerrado, portanto, a área assemelha-se a um ecótono de cerrado e floresta estacional semidecidual, com maior abundância e biomassa de espécies generalistas e típicas de cerrado. Dessa forma, a riqueza encontrada foi considerada alta em comparação com outros estudos realizados na FEENA, sendo indicada... (Resumo completo, clicar acesso eletrônico abaixo)

Classificação e mapeamento de áreas de risco de enchentes e inundações no bairro Jardim Inocoop - Rio Claro - SP

In the last few decades, Brazil has experienced an accelerated urbanization process in which many cities have grown in a disorderly way occupying environmentally fragile areas unsuitable for habitation. Anthropogenic actions such as high levels of impermeable soil, structural changes in watercourses, lack of riparian vegetation, illegal presence of trash and rubbish along the river banks added to irregular settlements in floodplains result in the rise of high risk areas. When accompanied by intense and prolonged rainfall phenomena, those areas have been the scenery of serious accidents such as floods. This study aims to classify the level of the risk of floods in the neighborhood of Jardim Inocoop, in the town of Rio Claro, São Paulo countryside, Brazil. One of the main technical support to tackle this issue is the identification and classification of the risks. In order to classify the risk level of flood in this case study, the methodology adopted was developed by the Ministry of Cities and Technology Research Institute, and take into account the arrangement of the hydrological scenario, vulnerability of households and dangerous process according to the distance of the houses from the axis of drainage. Therefore, the risk levels adopted to classify are listed below: very high (MA), high risk (A), moderate (M) and low risk (B). In conclusion, it is imperative to develop prevention plans in order to avoid or to minimize the damages caused by natural disasters. Therefore, the zoning of the risk sceneries remains as an important issue once it helps to identify the areas with high level risk of flood. Consequently, the occupation must be regulated where there is low or absent risk and it must be often forbidden where the high risk of flood is detected. Thus, the present study remains as an attempt to notify the risk of floods through its spatialization on a map, remainig...(Complete abstract click electronic access below)

Com base nos princípios da Permacultura foi analisado o contexto da área por meio de um estudo do ecossistema e da história da família e da cidade; os fluxos energéticos que influenciam no ecossistema; os elementos que fazem parte do sistema para que através de um zoneamento, criar novas relações entre os sistemas de produção com o objetivo de apresentar a viabilidade comercial de um sistema de produção sustentável em pequena escala

Bioma cerrado: um estudo de valoração e conservação da biodiversidade e dos recursos naturais

The region of the biome Cerrado is under threat due to the replacement of their native areas for expansion of agriculture and livestock. This occupation is responsible for the loss of about 50% of two million square kilometers of original native savannah. The land use, without control or zoning, has caused serious damage to natural resources of this biome, considered as an international hotspot area. As a result, some problems caused by ecological imbalances already topping the urban and rural environments, such as species extinction, water scarcity and desertification. Any occupation in this biome should be evaluated with caution, because this region, besides being considered one of the most productive of Brazil, is also rich in biodiversity and water resources. The understanding of the importance of the Cerrado biome and its remaining areas, allows the preparation of detailed studies of environmental valuation, which is essential for the development of conservation policies, avoiding even greater environmental impacts. To meet the growing demand for food, you can increase productivity through agroforestry, for example, and to preserve the remaining areas, you can create new protected areas and tailor existing units

Ecologia de cultivos: caracterização dos aspectos ecológicos dos diferentes cultivos no município de Cristais Paulistas-SP

Planning is an essential instrument for the agricultural occupation of the lands, because it supports the activities of food production and raw materials. It must be driven by techniques that provide the sustainability of these activities, so that also ensures the environmental balance of agroecosystems. Lands misuse can be considered as one of the causes of frustration of agricultural activities. Thus, the occurrence of discrepancies between the effective use (real use) of the land and its agricultural aptitude can compete, in many cases, to the decrease of productivity, as well as for soil degradation. In this way, this research intends to study the relationship between the temporary cultivations, halfperennial cultures, perennial and its developmental environment, determining the edaphoclimatic characteristics of landscapes. From then on, a letter shall be subject to the use and occupation of the soil for agriculture in the municipality of Cristais Paulista-SP, aiming to describe the spatial organization of land use and vegetation cover, and emphasizing management and conservative practices. For that, climatic factors were characterized, fundamentally humidity, temperature and luminosity; edaphics, including parental material, chemical and physical properties, fertility, soil temperature and climatic zoning; biotic, referring to the suitability of different cultures or to be implanted; physical, such as geomorphology, slope, geology, hypsometry and hydrology; socioeconomic, in particular production and marketing seasons; and the way they all, together, affect the adaptation, distribution and production of crops. Using this information, the zoning of the area of study was done based on the 21 nominated groups obtained, in addition to recommendations and suggestions for handling each type of cultivation...

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.

Análise geoambietal para o planejamento de obras civis lineares: uma abordagem por sensoriamento remoto orbital

Construction of linear engineering as, roads, ducts and multiducts as roads, has a strong feature of the diversity of land on which they are deployed. This diversity involves properties geological, geomorphological and structural variety. The purpose of this work is to characterize the physical environment in relation to their ability to support the implementation of civil works linear. To achieve this, the use of orbital remote sensing, in this case, Landsat - TM. Interpretative techniques are applied to images in order to assess the forms of relief and drainage found that they can set properties and have built a favorable meaning or not to implement these works. The results and thematic maps presented in this study allow us to promote the geoenvironmental analysis for the planning phase sustainable linear civil constructions (roads and multiducts)
