Abstract: in this work, data for criteria and non-criteria pollutants were obtained in a suburban industrial-residential area in rio de janeiro, from april to november 2002. formaldehyde and acetaldehyde concentrations were found in the ranges 25.25-231.73 ppb and 9.48-75.74 ppb, respectively. these high concentrations may be attributed to several sources: vehicular and industrial emissions, the presence of several trash incinerators, effluents and waste rejected in the faria timbó river and emissions from a methanol industry. average btex concentrations were: 1.92, 9.02, 6.37, 21.65 and 5.99 μg m-3 for benzene, toluene, ethylbenzene, m,p-xylene and o-xylene, respectively. pm10 concentrations showed maximum mean values in october, april and june. simulated concentrations were obtained for august 2002 using a trajectory model. the maximum calculated ozone concentration was 39.8 ppb, at 3:00 pm, in good agreement with experimental data (38.5 ppb). the ozone isopleths show that the local is in the high voc/nox region, typical of suburban and downwind areas.

Abstract: It is widely recognized that cities nowadays are confronted with (new) challenges like segregation and suburbanisation. This paper explores the idea that these processes are related with residential choices (or preferences) made by residents with divergent lifestyles and value patterns. The paper focuses on differences between urban and suburban lifestyles and residential preferences. Firstly the concept of lifestyles in general, and urban and suburban lifestyles more specifically, are approached. Secondly the results of a quantitative survey amongst residents within four neighbourhoods in the Ghent Region, a city in Belgium, are presented. This survey confirms that residents of urban and suburban zones have divergent lifestyles, but only for behavioural aspects, such as : private property protection, status behaviour and ecological behaviour. This results however in a social-spatial inequality and polarization between the urban centres and the suburban fringe. The shared aims amongst urban as well as suburban residents for a more secure residential environment and the ideal of the detached single-family house with private garden situated within a purely residential area, were identified as drivers for future suburban migrations. These residential preferences might cause (further) suburbanisation but do not need to lead to segregated social communities, since living with peers does not seem to be a driver for migration in Flanders, Belgium. Heel wat steden worden vandaag de dag geconfronteerd met een toenemende of voortschrijdende segregatie en suburbanisatie. Deze maatschappelijke en ruimtelijke processen worden in deze paper in verband gebracht met concrete woonkeuzes of -voor-keuren van de bewoners en met hun specifieke leefstijlen. In eerste instantie wordt in de paper stilgestaan bij het concept leefstijl, waarbij een onderscheid wordt gemaakt tussen latente leefstijlen, gerelateerd aan normen, waarden en karaktereigenschappen van de respondenten ; en manifeste leefstijlen, gekoppeld aan verschillende gedragspatronen. In concreto worden de resultaten van een kwantitatief leefstijlonderzoek in vier wijken in de Gentse regio gepresenteerd. Dit onderzoek bevestigt dat de inwoners van stedelijke en voorstedelijke gebieden uiteenlopende manifeste leefstijlen hebben. Dit resulteert in een sociaal-ruimtelijke ongelijkheid en polarisatie tussen de stedelijke centra en de suburbane rand. Zowel de stedelijke als de suburbane inwoners opteren in de toekomst voor een (nog) veiliger woonomgeving en voor een vrijstaande eengezinswoning met eigen tuin, gesitueerd

Abstract: Firstly, this paper selects 7 factors such as service facility, natural environment, traffic situation and location condition to evaluate Location Advantage Value of Residential Environment (LAVRE) in the urban and suburban areas of Beijing. Secondly, it constructs a LAVRE model to evaluate LAVRE of different parts of in Beijing and analyze its spatial characteristics. Thirdly, based on data of average prices of lots of commercial housings, this paper sets up GIS-based spatial distribution of prices to analyze spatial relationship between LAVRE and housing prices, and the relationship between LAVRE and residential location selecting behaviors. Lastly, it draws conclusions as follows: (1) Integrated LAVRE has a trend of decreasing from the center of the city to its periphery, and shows the feature of circle configuration. This trend is similar to the spatial change of the commercial housing prices, which shows a fact that the spatial distribution of commercial housing prices is directly influenced by the residential environment. (2) As a whole, the difference of commercial housing prices between northern and southern Beijing is similar to that of LAVRE. (3) Spatial preferences of residential location selecting are affected by the location advantage of residential environment. That is, northern Beijing where LAVRE is relatively high is the concentrated area of residential location selecting, and the rate of residents who choose southern Beijing, where LAVRE is low relatively, is lower than other parts of Beijing.

Abstract: Urban poverty continues to prove itself a concern in cities’ territorial planning as it disrupts the quality of life and the development process in some cities. Homelessness emerges sometimes as extreme urban poverty even in developed European Union countries. The study assesses Bucharest urban space to differentiate characteristics that influence the homeless to locate in certain places. The analysis included a three-level urban space categorization. Functional types of space were correlated to homelessness presence according to three space characteristics: property type, physical structure and state of use. The main findings argue that homeless people localization in Bucharest depends on urban space capacity to meet homelessness housing and living needs. Analysis’ conclusions evidence homeless location patterns to urban planners and authorities that may use the information to improve policies and actions to alleviate extreme poverty in Bucharest.

Abstract: This article outlines the perception of the urban image at micro-territorial level based on an analysis of data resulting from a survey conducted in large human habitats in Bucharest. The identification so achieved reflects numerous spatial similarities of the perceptions of the urban image. The landmarks that the residents of Bucharest have in this respect are in line with the built areas as well as those related to the basic destinations of everyday life. This gives rise to quite a big issue: the people of Bucharest living in such large dwelling compounds are restricted to a superficial knowledge of space. They are impacted by a much too quickly changing urban policy and by permissive building investment rules that have lead to a variegated puzzle of post-communist restructurings where essence is attached to just trivial landmarks..

Abstract: The undergoing concerns for local and regional development focus also on the territorial analyses. The local socio-economic analysis is naturally followed by the strategic planning of development during which the local public authorities initiate and organize, locally, the economic development of the respective territorial unit. This article is intended to analyze a concrete case, that of the Capital City of Romania, the Municipality of Bucharest. One of Romania’s objectives is to sensitize and educate the civil society, the private organizations and the public authorities towards understanding and observing the urban landscape. In the spirit of the aspects mentioned above, the authors have presented a case study, at the end of this article, in which the reconsideration of the urban architectural framework matches perfectly with the wish of introducing elements of spatial dynamics and of balance. In this spirit, the over-crowded City of Bucharest, which has a density of 9009 inhabitants/sq.km, will potentially be turned into an oasis of social comfort that will positively influence the urban organism.

Abstract: Background As the population is ageing rapidly in Beijing, the residential care sector is in a fast expansion process with the support of the municipal government. Understanding spatial accessibility to residential care resources by older people supports the need for rational allocation of care resources in future planning. Methods Based on population data and data on residential care resources, this study uses two Geographic Information System (GIS) based methods – shortest path analysis and a two-step floating catchment area (2SFCA) method to analyse spatial accessibility to residential care resources. Results Spatial accessibility varies as the methods and considered factors change. When only time distance is considered, residential care resources are more accessible in the central city than in suburban and exurban areas. If care resources are considered in addition to time distance, spatial accessibility is relatively poor in the central city compared to the northeast to southeast side of the suburban and exurban areas. The resources in the northwest to southwest side of the city are the least accessible, even though several hotspots of residential care resources are located in these areas. Conclusions For policy making, it may require combining various methods for a comprehensive analysis. The methods used in this study provide tools for identifying underserved areas in order to improve equity in access to and efficiency in allocation of residential care resources in future planning.
Territorial Disparities in the Population Dynamics. Comparative Analysis Between Bucharest-Ploie ti Corridor and Bucharest-Pite ti Corridor
Romanian Review of Regional Studies , 2012,
Abstract: The present paper is a comparative analysis of territorial disparities in the population dynamics of the settlements along two corridors of major national importance. The objective is to prove that a key corridor starting in the capital city of a country has both positive and negative effects on the network of settlements it goes through. The capital influence is widely felt in both areas studied, nevertheless there are differences which were analysed starting from the premise that the borders of Bucharest metropolitan area are currently up to 50 km around the capital and that the area of influence is continuously expanding territorially. These differences are generated by the fact that although Bucharest is a major pole of social-economic phenomena, its influence on the settlements in the neighbouring area varies in intensity because urbanisation, development and modernisation are intense, but within a limited area. The existence of the two corridors had an impact upon the configuration of localities causing the extension of the built-up areas in the localities close to the roadway, especially parallel to it. This is particularly related, but it is not limited to the increase in the supply of/demand for land plots earmarked for building dwellings of a higher standard – main or secondary residences. The evolution of the population dynamics of the settlements alongside the two corridors is closely related to the social-economic changes occurred in the area influenced by the three cities (Bucharest, Ploie ti and Pite ti) and to the intensification of urbanisation.
Forecast the Impact of Bucharest – Bra ov Highway on the Economic and Functional Structure of Human Settlements in Ilfov County
Romanian Review of Regional Studies , 2011,
Abstract: One of the most publicized issues concerning the infrastructure of Romania is the Bucharest-Bra ov highway. The long-awaited project aims to streamline the traffic between the Capital and the central part of the country, representing the central area of the Pan - European Road Corridor IV. The length of the highway on the territory of Ilfov County is 31 km, representing 17% of the total length of Bucharest- Bra ov highway. The start of the highway will have strong effects on economic structure and on the way the Bucharest Metropolitan Area will work. We can expect an increase in the disparities between the settlements of Ilfov County. This pattern is also observable on the Bucharest-Ploie ti corridor where, in recent years, much of the Ilfov county's economic activities have migrated to the north, especially along that corridor. Besides economic migration, intense residential migration followed the Bucharest – Ploie ti corridor, residents of the Bucharest itself moving out to the north of Ilfov County. Probably, the future Bucharest – Bra ov highway will lead to an increased suburbanization and periurbanization, this in turn giving way to the crowding of the area by businesses eager to have access to the highway. This project will likely increase the gap between north and south of Ilfov County. In addition to changes that may occur at the county level, changes will also have an impact on the localities themselves since the areas located near the highway will have an economic and demographic growth rate superior to more remote areas. In this sense, we conducted a comparative analysis between eight settlements of Ilfov county crossed by the Bucharest-Bra ov highway in order to assess the impact. This analysis was based on the information obtained from site and statistical indicators that were processed to obtain a clear picture of the situation in the examined territory.
