O crescimento urbano tem gerado diversos problemas socioambientais, os quais tem origem na atividade humana, que por sua vez, causam danos para o ser humano e para o ambiente. As inundações urbanas são considerados problemas socioambientais urbanos uma vez que as populações são atingidas pelas mesas devido a construção de residências em APP´s. Partindo destes pressupostos, o presente trabalho objetiva realizar a análise espacial da sub-bacia hidrográfica do riacho do Angelim a partir do mapeamento das áreas inundáveis e da espacialização social da renda mensal dos chefes de família na área de estudo. Para isto foram realizados alguns procedimentos metodológicos, tais como: levantamento bibliográfico e cartográfico, organização do ambiente de trabalho, realização de trabalhos de campo, mapeamento das áreas inundáveis, renda e análise espacial das áreas inundáveis. A partir dos dados obtidos foram mapeadas 5 áreas inundáveis na área em estudo as quais são APP’s. As mesmas estão inseridas em compartimentos geomorfológicos mais frágeis e inadequados para a ocupação humana. Concluiu-se que a ineficiência das leis brasileiras associada ao processo de ocupação determinado pelo mercado imobiliário têm contribuído para a segregação espacial dos indivíduos.Palavras-chave: Análise espacial, riacho do Angelim, renda, nascentes e inundações. RESUMENEl crecimiento urbano ha generado varios problemas socioambientales, que se originan en la actividad humana, que a su vez causan daños a los seres humanos y al medio ambiente. Las inundaciones urbanas se consideran problemas socioambientales urbanos ya que las poblaciones se ven afectadas por las tablas debido a la construcción de residencias en APP S. Basado en estos supuestos, el presente trabajo tiene como objetivo realizar el análisis Espacial de la subcuenca hidrográfica del arroyo Angelim a partir del mapeo de las áreas inundadas y la espacialización social de los ingresos mensuales de los jefes de familia en el áreade estudio. Para ello, se llevaron a cabo algunos procedimientos metodológicos, tales como:encuesta bibliográfica y cartográfica, organización del entorno de trabajo, trabajo de campo, mapeo de áreas inundadas, ingresos y análisis espacial De las zonas inundadas. A partir de los datos obtenidos, se mapearon 5 áreas inundadas en el área en estudio, que son APP' Se insertan en compartimentos geomorfológicos más frágiles e inadecuados para la ocupación humana. Se concluyó que la ineficiencia de las leyes brasileñas asociadas con el proceso de ocupación determinado por el mercado inmobiliario han contribuido a la segregación espacial de los individuos.Palabras-clave: Análisis espacial, corriente Angelim, ingresos, manantiales e inundaciones. ABSTRACTUrban growth has generated several socio-environmental problems, which originate in human activity, which in turn cause damage to humans and the environment. Urban floods are considered urban socio-environmental problems since the populations are affected by the tables due to the construction of residences in APP ´ S. Based on these assumptions, the present work aims to perform the analysis Spatial of the hydrographic sub-basin of the Angelim Creek from the mapping of the flooded areas and the social spatialization of the monthly income of the heads of family in the study area. For this, some methodological procedures were carried out, such as: bibliographic and Cartographic survey, organization of the work Environment, fieldwork, mapping of flooded areas, income and spatial analysis Of the flooded areas. From the data obtained, 5 flooded areas were mapped in the area under study, which are APP's. They are inserted in more fragile and inadequate geomorphological compartments for human occupation. It was concluded that the inefficiency of Brazilian laws associated with the occupation process determined by the real estate market have contributed to the spatial segregation of individuals.Keywords: Spatial analysis, Angelim Creek, income, springs and floods.

Urban/social fragility is the main focus of most studies on civil economy involving the commitment of politics in the prospect of integrating and somehow guiding an ordered development of and ordered communities. The contemporary city is strongly influenced by the incommunicability between the social system and environment, the latter more and more, including urban and societal components. This study tries to outline a comparative social-urban profile of Picanello, a popular central neighborhood of Catania, in Sicily, Italy, characterized by the combination of different urban and social life-quality levels, thus expressing a heterogeneous vulnerability/resilience profile. The analysis is placed in the urban planning context and aims to: (1) Denotative a pattern that considers the different fragility/resilience descriptive indices; and (2) connotative a pattern of the human and urban dimensions of the social capital asset. This analysis was performed by implementing a multidimensional pattern allowing us to place the neighborhood in a ranking of the neighborhoods of Catania, thus highlighting strength and weakness under different respects. Furthermore, the monetary measurements of this vulnerability/resilience profile, was carried by means of the structured observation of the real estate market. Fuzzy k-medoids cluster analyses have been comparatively performed—showing and mapping the relationships between urban value density and real estate market prices tensions.

Abstract. This paper examines the main features of the social production process of condomínios fechados across the Lisbon Metropolitan Area. This residential form first appeared in Portugal in the 1980's and spread quickly in the 1990's. The article opens with a preliminary analysis of the development of secured residential complexes, aimed at understanding its specificity and pinpointing the main factors involved in its social production. In this analysis, we do not focus on the Lisbon Metropolitan Area (LMA) alone but rather adopt a broader approach. In the second chapter we describe the research methods used, such as a survey of condomínios fechados built in the Lisbon Metropolitan Area between 1985 and 1999, interviews with social actors and content analysis of promotional materials. Finally, we present selected research results and discuss several issues central to understanding the social production of gated housing estates in the LMA, including the importance of foreign modeis, the supply side agency of the real estate market, and the broader social context.

The article deals with the application of spatial analysis methods in assessing the real estate market. Real estate is viewed not only as a type of property but also as a tangible asset. Each participant in the real estate market solves one of two tasks: improving housing conditions or a profitable investment of capital. The selection of the most suitable real estate option that meets the criteria chosen by the purchaser is the most urgent task: theoretical and mathematical, statistical, cluster analysis. The city of Rostov-on-Don was chosen as the main object of the study. This choice was due to the high population density, the presence of a developed infrastructure: socially significant facilities (schools, kindergartens, hospitals, post offices, MFC offices), sports and entertainment centres, as well as a developed transport network. The main criterion for determining the most suitable service for obtaining the initial data for the study was the largest number of ads. The analysis of platforms containing information about real estate allowed us to choose the Avito service, which has the most complete database, as a data source. To collect data, a parser program was used that performs parsing. The information obtained was processed on a computer using spatial analysis software. The cartographic basis of the project is a map of the OpenStreetMap service.

Em meados dos anos 1960, Itinga - em Lauro de Freitas, município da Região Metropolitana de Salvador - era considerada uma área distante, caracterizada pela presença de grandes fazendas abandonadas, sendo, portanto, uma terra que não despertava interesse comercial. Nesta mesma década, dentre as conseqüências da inserção da Bahia no projeto de industrialização nacional, ocorreram alterações na estrutura sócio-espacial de Salvador que expandia sua ocupação e lógica para municípios contíguos, como Lauro de Freitas. Itinga, então, na condição de periferia de Salvador, passou a ser objeto interessante ao mercado imobiliário: no seu território foram implantados, rapidamente, inúmeros loteamentos populares, sem qualquer infra-estrutura, apresentando precárias condições de vida. Em 2005, Itinga, consolidada como bairro popular, contava com inúmeros loteamentos populares, estabelecimentos comerciais e de serviços públicos e privados. As condições de vida mudaram e, como dizem seus moradores, o “progresso” do bairro é visível. Porém, Itinga ainda é periferia, tanto de Salvador, como de Lauro de Freitas. Nesse sentido, este artigo pretende discutir algumas das implicações de morar na periferia, para tanto se analisam as condições de moradia em Itinga, no início de sua “urbanização” e atualmente, comparando-as com as existentes em outros bairros de Lauro de Freitas. Abstract In the middle of the 1960s, Itinga — located in Lauro of Freitas, municipality of the Metropolitan Area of Salvador — was considered a distant area and characterized by the presence of great abandoned farms, therefore, being a land that attract no commercial interests. On that same decade, among the consequences of the insertion of Bahia State in the national project of industrialization, it happened some alterations in the social-spatial structure of Salvador that expanded its kind of logic and spatial occupation to contiguous municipalities, like Lauro de Freitas. So, Itinga, under the condition of peripheral district of Salvador, started to be an interesting object to the real estate market: in its territory it was quickly established countless popular divisions into lots, without any infrastructure and presenting precarious life conditions. In 2005, Itinga, consolidated as popular neighborhood, counted with countless popular divisions into lots, commercial establishments and public and private services. The life conditions changed and, as their residents use to say, the “progress” of the neighborhood is visible. However, Itinga is still periphery of Salvador and, at the same time, periphery of Lauro de Freitas. In that sense, this article intends to discuss some of the consequences of living in the periphery, for so much, it analyzes the living conditions of Itinga at the beginning of its “urbanization” and nowadays, and it compares such conditions with the existent ones, in other neighborhoods of Lauro de Freitas.
