The urban sprawl of the big brazilian cities of accelerated and disordered way sets up one of the main problems of sociable environmental character and which contribute to the distortion of natural landscapes. In this context, the water bodies, depending on your climate and landscape importance, were also influenced by this process. Thus, this research aims to analyze the changes in the surroundings of Jacarey Lake, from a time space evaluation and of the main vectors of expansion, contributing to a discussion on the environmental problems arising from the urban occupation. To do this, we conducted a survey, cartographic, bibliographic and documentary in order to analyze the urban density in the vicinity of the water body, in addition to characterize the main environmental impacts in the area. The results indicate that the water body had your occupation process accelerated mode elapsed, depending on the growth of the city of Fortaleza to your East side, which contributed to a higher valuation of urban land, however, bringing with it a host of environmental problems.

This paper aims to analyze the current territorial characteristics of the Brazilian Center- North-Amazon region, based on the Cerrado and the Amazon Forest, identifying the elements that outline the capitalist frontier in this early 21st century. It highlights the way that medium-sized cities have served the capitalist precepts in the recent process of urbanization of the region and seeks to relate the transformations that occurred in the Cerrado territory from the modernization imposed by capitalism, through an urban restructuring through which the Midwest region. It has been going through the process of expanding the economic frontier over the Amazon since the mid-twentieth century, also highlighting the urban restructuring of the eastern Amazon. It starts from the understanding that the Brazilian State fits the demands of the world capitalism through the implantation of the urban-industrial model. The urbanization of this region, the result of regional development policies implemented mainly after the 1940s, became a viable action of this condition and the state arrangements allow investing in infrastructure, creating planning agencies and providing population migratory flows towards the cities that polarize in the territory, concentrating surplus of cheap labor and boosting urbanization in the Amazon. The approach method is the Historical and the detached analysis is the Dialectic, and this work is the partial result of a research component of the projects "PGPSE/CAPES Territorial Development and Sociobiodiversity: perspectives for the Cerrado world" and "PROCAD/CAPES Territory, Environment and Rural-Urban- Regional Dynamics in the Brazilian Amazon".

The Brazilian Amazon is a fertile space for the re (production) of urbanization in an expanded and fragmented way. The study aims to discuss the emergence of the urban on the Amazon frontier, taking as a case study the urban centers of the municipality of Rorainópolis-RR. It is a space significantly affected by the policies of colonization and Agrarian Reform, introduced by the Federal Government since the 1970s. In this space, small nuclei emerge, with an incipient urban infrastructure that tend to evolve and become municipal headquarters. The study included data collection in the field, cluster analysis and analysis of variance. The results showed the existence of six population centers in the municipality of Rorainópolis, namely: the municipality's headquarters, and the protourban centers of Nova Colina, Ecuador, Jundiá, Martins Pereira and Boa Esperança. It was observed the existence of a hierarchy between the nuclei. This is manifested from the differentiated offer of goods and services, verified by the presence of certain equipment considered urban. The study brings relevant contributions to understand the dynamics of genesis and evolution of the urban on the Amazon frontier. [ABSTRACT FROM AUTHOR]

The city of Boa Vista, capital of the State of Roraima, passed by changes in its physical and social structure intensified in the late twentieth century and early twenty-first largely brought by the government. In the West Zone irregular occupations have been multiplying in the 1980s and 1990s, contrasting with the East Zone well organized. In this sense the present work deals with the planning and management actions for the city in an attempt to (re) organize the urban space through the Director Plan for Urban Development 1991 and the Strategic and Participative Director Plan 2006 focusing on an area of strategic leisure, the Municipal Park Germano Augusto Sampaio located in the West Zone. Physical and social aspects of the site were considered in a temporal analysis based on satellite images and data collected through field research, which established that the urban public policies in the city, despite the importance social, do not comply with Brazilian environmental laws which results in the degradation of natural resources.

This article addresses the question countryside-city under various methodological perspectives, making a rescue of conceptual discussion and especially the analysis of the geographical point of view, in other words, the relation countryside-city from the spatial dynamics. Approach will bring the countryside to the cities from three points of view: the spaces periruban, the New Rural and Hybridity Space. [ABSTRACT FROM AUTHOR]

The economic restructuring that characterizes the current historical period also affects the agricultural sector and results in diffusion of globalized agribusiness in Brazil. Such processes are at the heart of the explanation of many new Socio-spatial dynamics and are responsible for restructuring the agricultural area, urban and regional in various parts of the country. As a result, we could highlight: the increase of the density-technical-scientific informational in agriculture space; new distribution of productive functions by territory; diffusion of productive specializations; intensification of social and territorial division relations work; new relations field-city; intensification of urbanization of society and of the territory; urban and city redevelopment etc. The main objective of this text is to put for debate some of the main themes and processes that are at the basis of the analysis of new forms of use and occupation of the Brazilian territory from the globalized diffusion of agribusiness, considering that this is one of the main vectors of (re)production of space in the country.

This paper aims to analyze the production of gated communities in the city of Macapá - capital of Amapá State - as part of urban restructuring that has been reaching medium cities of Amazon in the beginning of the nineteenth century. It understands that gated communities, with a set of modernizing source objects, such as shopping center, luxury hotels, new cinema halls, vertical buildings, playhouse auditoriums, represent the new content of the region medium cities urbanization. Even if the construction of gated communities in Macapá has been, on the beginning, the only choice that middle class - above all the one associated to public sector - found for access to housing, nowadays these communities assume a new socio-spatial content and are presented as part of the urban restructuring that has been reaching brazilian medium cities.

This work aims to evaluate the effects of urbanization on the drainage network of the Caranã stream in the Boa Vista city in Roraima state. The study included the basins of the Caranã stream, which drains the urban area, and Carrapato stream, located adjacent to this city and has geomorphological characteristics similar to the first stream. The work was supported by the interpretation of satellite images, the identification and mapping of drainage networks before and after urbanization, supported by field visits, as well as the basic survey of the discharge of the two basins. The results showed that urbanization was derived from Boa Vista in a slight increase in the extent of drainage area (2.7km) and a significant reduction of the lake basin Caranã stream, represented by the drainage of lakes, with the reduction of these areas 6.77to 3.03km2. It was found that the low gradient portions of the lake drained and the high volume of precipitated during the high season (May-July), determine a low efficiency in the drainage of these environments. It was verified that urbanization and drainage lacustrines environments resulted in altering the hydrology of the Caranã stream, which increased the amplitude of annual discharge, with higher flow rates during the wet season and smaller discharges at the top of the dry season.

In the last decades, landslides along hillsides have increased considerably, especially in under-developed countries. The gravitational movements of land masses are worsened due to the constructions of habitations on steep hillsides, and so altering the urban scenery. The general objective of this research is to carry through a study on the landslides of hillsides in the slum quarters Brtitador and Vila Santo Antonio located in Campos do Jordão-SP. Besides these two slums, Campos do Jordão has three other slums witch are believed to be in high risk areas: Vila Albertina, Monte Carlo and Cachoeirinha, around 1200 people reside in this five slums. Its understood that these slums are of Brazilian urbanization are areas of social space segregation, and representations of the outskirts of Brazilian cities.The Geographic awareness of the landslides along the hillsides in the city of Campos do Jordão was founded due to the search of human answers to the problem. The perceptive approach given in this research will not only contribute to the adoption of strategies which could be made by the city's public council, but also to the acknowledgement by the individuals who dwell in this slums in relation to the landslides which take place along these hillsides.This study get started due to the presupposition that the people living in these areas of risk , are vulnerable to landslides and put themselves to the mercy of luck, and not even the experience acquired in past landslides will free them from the exposition to tragedy that a new landslides can brig about.
