Emprego de imageamento passivo na análise da variabilidade espacial da turbidez no espelho d'água do Lago Paranoá, Distrito Federal

The water has an important role in human society, especially in Brazil. Its uses are multiple, including supply, energy production, recreation and others. The National Policy for Water Resources (Law No 9.433/97) states in its articles the importance of water use in accordance to their multiple uses, prioritizing the supply for humans and animals. In this approach, it is important to consider the physical and chemical quality of water to meet these demands, scope of the legal framework applied to the Brazilian water bodies according to their main uses, in order to guarantee the water quality compatible with the most demanding uses and to reduce the costs of pollution control through ongoing preventive actions. Among the various parameters that seek to analyze the physical and chemical quality of water it is intended to understand the spatial distribution of turbidity in the lake's surface, since the variation of the components that alter this parameter can be detected by means of passive remote sensing. The application of the Linear spectral mixture model allowed, satisfactorily, the identification of turbidity spatial distribution patterns in the lake.

Variabilidade espacial de atributos físicos de solos antropogênico e não antropogênico na região de Manicoré, AM

Better knowledge of the anthropogenic soils can help create future scenarios for the Amazon region through information that supports the sustainable planning. The aim of this study was to evaluate the spatial variability of soil physical anthropogenic and not anthropogenic in the region of Manipur, AM. In the study area we selected two, one with no anthropogenic soils (native forest) and another with anthropogenic soils (black earth archaeological). In each area, we established a grid measuring 70 x 70 m and the soils were sampled at the points of intersection of the grid with regular spacing of 10 by 10 feet, making a total of 64 sampling points in each landscape. Soil samples were collected at a depth from 0.0 to 0.10 I did the analyzes physical (texture, bulk density, macroporosity, microporososidade, porosity and aggregate stability). Then, the data were subjected to descriptive statistics and geostatistics. It was found that the anthropogenic and non-anthropogenic soils showed different behaviors in relation ace their spatial structures. The spatial variability that prevailed in anthropogenic and non-anthropogenic soil was moderate and weak indicating that these soils are strongly linked to changes in the soil by extrinsic factors. The soil was observed anthropogenic best results for total porosity, microporosity and bulk density, showing superior characteristics compared for agronomic soil not anthropogenic. And the range of values found in the above two areas were used in the mesh, showing greater spatial continuity in these environments.

Dependência espacial da estabilidade de agregados e matéria orgânica do solo em cambissolo sob cultivo de cana de açucar

The soil management system can modify the natural distribution of the soil attributes and, consequently, the variability of the soil aggregation and organic matter content. Thus, the aim of this work was to evaluate the aggregate stability and organic matter content spatial distribution on a Haplic Cambisol under sugar cane cultivation in the Southern Amazonas State, Brazil. A 70 x 70 m square mesh, with regular 10 meters intervals, was designed over the cultivation area, resulting in 64 sample points. Soil blocks with preserved structure were collected at 0.0-0.2 m depth in order to analyze the aggregate stability and organic matter content. The data were submitted to the descriptive and geostatistical analysis. The soil attributes presented a spatial dependence structure and the greater range was observed for the mean weighted diameter and aggregate class <1.00 mm. Also, there is a spatial relation among the mean geometric diameter, mean weighted diameter and aggregate classes (>2.00 and 2.00-1.00 mm).

Estudo da distribuição espacial dos condomínios horizontais fechados e loteamentos fechados na cidade de Rio Claro-SP

In Brazil, the proliferation phenomenon of gated communities and land lots had its origins in big cities, such as Rio de Janeiro and Sao Paulo, since 1970. The implementation of these types of intramural housing are done in expanding are as of the city, based on the availability of bigger lots, lower land prices, and the search for are as closer to nature. The gated communities and land lots that, initially, had their architecture only accessible to the higher social classes, as a second home alternative away from urban problems, nowadays they can be reached by other social classes as well. Gated communities and land lots find their way to the center of larger cities, sustained mostly by the speech of real state entrepreneurs, and by its social “status”, a new emerging characteristic of this time period. The expansion of gated communities and land lots also change the cities lands cape and social spatial configuration. This work, therefore, attends the localization of gated communities and land lots spread out in the city of Rio Claro. It analyzes the scale in which the dynamics of the city’s urban expansion influenced the current distribution of these types of housing

Circuito espacial produtivo e círculos de cooperação dos café Fairtrade: análise da Associação dos Agricultores familiares do Córrego D'Antas (ASSODANTAS), Poços de Caldas/MG

The aim of this research project is to analyze the spatial productive circuit and circles of cooperation of Fairtrade coffee, taking as a case of study the Associação dos Agricultores Familiares do Córrego D'antas (ASSODANTAS), Poços de Caldas - MG. The main purpose is to analyze material flows (grains, supplies, etc.) established between geographically separated stages of production (production, exchange, distribution and consumption) and the relationships between the agents in order to analyze the organization and regulation of production of Fairtrade coffee. It is understood as the insertion of the Fairtrade ASSODANTAS to permit the creation of new production lines, adding value and providing greater identity and autonomy to their small farms, when compared with traditional coffee trade commodity
