O mercado imobiliário e a reinvenção da Ribeira, Natal - RN: verticalizar para renovar?

The real estate dynamic originates new spatial forms, which can determine new uses and new places. We tried to analyze this work, the spatial transformations in the Ribeira district, Natal / RN, due to the advancement of the housing market that is gradually transforming the landscape with the introduction of new types of housing, especially by verticalization. The verticalization of the neighborhood occurs almost at once, changing the local landscape. Notwithstanding this process, given the rapid growth of Natal in the last two decades and the strategic location of the neighborhood, it is pertinent to note that, if not the process of vertical integration, perhaps the neighborhood had been at the mercy of other urban interventions and other approach the real estate market. The research used as instruments interviews with actors who work in the property market in the town and representatives of organizations that have implemented major legislation in the area, the Instituto de Patrimônio Histórico e Artístico Nacional (IPHAN) and the Secretaria de Meio Ambiente e Urbanismo (SEMURB) as well as photographs on the area, in order to verify this new configuration that has been consolidated in the district. To support the theoretical discussion, there was a documentary and bibliographical research. In this way, the object of study of this search sees the uniqueness of urban renewal in the district of Ribeira and its relationship with the historic preservation laws and incentives for residential occupation in the neighborhood, especially regarding the vertical building

(Con)vivendo em fortalezas: o outro lado do morar bem

The intensification of the fear in the city and in the spaces controlled by this feeling has contributed to a growing socio-spatial inequality, and the rapid growth of market protection. The residential condos emerge as a possible solution to the problem. This is a housing typology expanding worldwide which is seen, especially by the urban middle class, as enablers of quality of life and safety. In Brazil, especially in large cities, the quest for quality of life is directly connected with the desire for security translated through space control (use of high walls, gates, entrance hall, security cameras) and people who use it. This thesis aims at investigating how the different categories of inhabitants of an area predominantly occupied by vertical residential condos realize the socio-spatial dimension and the socio-urban space determined by this type of development. It especially takes into consideration the issue of urban insecurity, based on the assumption that, although published and sold by marketing as safe places , synonym of welfare and supporters of community life , the living in these condos, may even inhibits, social relationships, contributing to socio-spatial isolation and consequent social weakness. This is a survey that seeks to meet the assumptions of Environmental Psychology towards the comprehension of person-environment studies, emphasizing the use of different methods (desk research, observations of and group interviews, focus group technique using photographic resources), as well as the focus on current problems of the urban scene and the knowledge gained in Social Psychology

Caracterização sócio-ambiental do bairro de Felipe Camarão- Natal/ RN

The rapid growth of the Brazilian cities in the latest years has brought a series of problems regarding housing policies and, therefore, the provision of dwellings for the low-income class people. Following the pattern of other capital cities, Natal has repeated the pattern of urbanization practiced in the country, which concentrates the low-income class inhabitants in specific zones of the city known as peripheries or even in a dwelling place for less-favored classes such as Felipe Camarão, which is one of ten boroughs belonging to the western administrative zone, a region which has historically received less attention from the public administrators towards infrastructure investments. Based on those aspects, the general objective of this work is to investigate which main social-environmental alterations have resulted from the processes of urbanization and field occupation in that area. The specific objectives are concerned with verifying 1) the process of urbanization and the process of dividing urban soil from the 1960s; 2) the current configuration of the public spaces in the borough; 3) the process of the deprivation of the original landscape characteristics of Environmental Protection Zones; 4) the dynamics of land occupation which are predominant in dune areas; 5) the dynamics of land occupation which are predominant in mangrove areas; 6) and the destruction of green covering on the land with its consequent alteration of the local floristic pattern. The methodology consisted of in-loco visits; the application of questionnaires as community research; a survey of bibliography published by the organisms and institutions in charge of carrying out the city hall s environmental and housing policies; and descriptive statistics of the collected data. Concerning the pattern of occupation which is predominant in the borough, the treatment of space dispensed by the local dwellers has culminated in the emergence and consolidation of environmental alterations which are clearly different from common occurrence in both the building area represented by housing complexes and in the green areas represented by dunes and mangroves. The data show that there was the predominance of the irregular land occupation process over the official housing policy during the population settlement which contributed with a series of frequent and foreseeable problems in the dynamics of urbanization of poverty such as invasions and appropriations of land parcels, the beginning of irregular arrangement of streets, the formation of villages and slums, which are full of self-constructed housing units, and the occupation and degradation of susceptibly fragile environmental areas such as the dune slopes and the mangroves

Avaliação de impacto ambiental e gestão dos recursos natuarias no estuário Apodi Mossoró, nordeste do Brasil

The aim of this study is to investigate the eco-environmental vulnerability, its changes, and its causes to develop a management system for application of eco-environmental vulnerability and risk assessment in the Apodi-Mossory estuary, Northeast Brazil. This analysis is focused on the interference of the landscape conditions, and its changes, due to the following factors: the oil and natural gas industry, tropical fruits industry, shrimp farms, marine salt industry, occupation of the sensitive areas; demand for land, vegetation degradation, siltation in rivers, severe flooding, sea level rise (SLR), coastal dynamics, low and flat topography, high ecological value and tourism in the region and the rapid growth of urbanization. Conventional and remote sensing data were analyzed using modeling techniques based on ArcGIS, ER-Mapper, ERDAS Imagine and ENVI software. Digital images were initially processed by Principal Component Analysis and transformation of the maximum fraction of noise, and then all bands were normalized to reduce errors caused by bands of different sizes. They were integrated in a Geographic Information System analysis to detect changes, to generate digital elevation models, geomorphic indices and other variables of the study area. A three band color combination of multispectral bands was used to monitor changes of land and vegetation cover from 1986 to 2009. This task also included the analysis of various secondary data, such as field data, socioeconomic data, environmental data and prospects growth. The main objective of this study was to improve our understanding of eco-environmental vulnerability and risk assessment; it´s causes basically show the intensity, its distribution and human-environment effect on the ecosystem, and identify the high and low sensitive areas and area of inundation due to future SLR, and the loss of land due to coastal erosion in the Apodi-Mossoró estuary in order to establish a strategy for sustainable land use. The developed model includes some basic factors such as geology, geomorphology, soils, land use / land cover, vegetation cover, slope, topography and hydrology. The numerical results indicate that 9.86% of total study area was under very high vulnerability, 29.12% high vulnerability, 52.90% moderate vulnerability and 2.23% were in the category of very low vulnerability. The analysis indicates that 216.1 km² and 362.8 km² area flooded on 1m and 10m in sea levels respectively. The sectors most affected were residential, industrial and recreational areas, agricultural land, and ecosystems of high environmental sensitivity. The results showed that changes in eco-environmental vulnerability have a significant impact on the sustainable development of the RN state, since the indicator is a function of sensitivity, exposure and status in relation to a level of damage. The model were presented as a tool to assist in indexing vulnerability in order to optimize actions and assess the implications of decisions makers and policies regarding the management of coastal and estuarine areas. In this context aspects such as population growth, degradation of vegetation, land use / land cover, amount and type of industrialization, SLR and government policies for environmental protection were considered the main factors that affect the eco-environmental changes over the last three decades in the Apodi-Mossoró estuary.

Aclimatização de mudas de bananeira em substratos contendo resíduo de mineração de areia

Para o rápido crescimento de mudas de bananeiras produzidas por micropropagação é necessário a utilização de substratos com adequadas características físicas, químicas e biológicas. Objetivou-se avaliar os atributos químicos e físicos de diferentes substratos contendo resíduo de mineração de areia e seu efeito sobre o desenvolvimento de mudas micropropagadas de bananeira 'Grande Naine', dispostos em delineamento em blocos ao acaso, com sete substratos e quatro repetições. Os materiais utilizados foram: resíduo de mineração de areia (RMA), Rendimax Floreira® (RF®) e casca de arroz carbonizada (CAC), com os quais se formulou os substratos: S1-100%RMA; S2-50% RMA:50% RF®; S3-50% RMA:50% CAC; S4-50% CAC:50% RF®; S5-25% RMA:37,5% CAC:37,5% RF®; S6-50% RMA:25% CAC:25% RF®; S7-75% RMA:12,5% CAC:12,5% RF®. Amostras dos materiais e dos substratos foram separadas para análises químicas e físicas. Noventa e oito dias após o transplante avaliou-se a altura, o diâmetro do colo, o número de folhas e a massa da matéria seca da parte área e das raízes das plantas. Os pHs dos substratos se encontraram na faixa adequada para o cultivo de plantas em recipientes. A CE diminuiu à medida que se aumentou a dose de RMA nos substratos. Os substratos S2, S6 e o RF® apresentaram resultados superiores para a densidade seca. Os substratos S2, S4, S5, S6 e S7 forneceram plantas superiores em altura e diâmetro do colo e, acrescidos do substrato S1, forneceram plantas superiores também no número de folhas e massa de matéria seca da parte aérea. Conclui-se que o RMA pode ser recomendado para a aclimatização de mudas micropropagadas de bananeira 'Grande Naine', desde que usado em mistura com outros materiais ou substratos, com limite máximo de 75% de inclusão.
