title: Informal public open space as locus of the opportunity and of social-spatial integration of city: the case of the Beira Molhada slum, in João Pessoa, Paraíba - Brazil

description: Abstract Public open spaces are key to cities, as a place where society can create and recreate public life. Thus, we aim to investigate the production of these areas in slums through concepts such as “right to the city”, “return to the city”, accessibility, mobility, and the implications of fragmentation and segregation, in promoting the socio-integration into the city. The empirical object is the “Beira Molhada” slum in João Pessoa, Paraíba, because of its inclusion in peri-urban area and of environmental preservation, with large public open spaces. The methodology consists of literature and documentary research, mental maps and geo-referenced analyticals. The results indicate an issue poorly related with city and environmental goods under threat. However, there is great potential for socio-spatial integration of the slum with the city, by encouraging social dynamic that provides accessibility and mobility to the environmental heritage and its fruition, contributing to the establishment of an “urban society” as stated by Lefebvre.

title: Reconquista river basin in the metropolitan planning of Buenos Aires (Argentina). Scope, problems and proposals

description: Abstract Reconquista River Basin is one of the three major basins in the metropolitan region of Buenos Aires (Argentina) seriously affected by flooding and pollution. As part of the metropolitan city, the Reconquista river basin was considered in the urban planning documents that were developed for the region during the second half of the Twentieth Century: the Plan Regulador de Buenos Aires, the Esquema Director Año 2000, Estudio del Sistema Metropolitano Bonaerense and Proyecto 90. Regardless of whether or not they were realized, the plans reveal ways of thinking and operating in the river basin as an area within the city, as a problem of metropolitan scope and as a proposal for territorial transformation in three stages: firstly floods and hydraulics, secondly environment and quality of life, and thirdly ecology and landscape, in which the relationships established between urbanization, urbanism and river basins changed.

title: Heritage Railway: in search of their central places

description: Abstract The railway heritage is formed by complex structures and socio-spatial interactions – built as a network - linked to the history of scientific and technological development and to social memory. Thus, these structures carry evaluative attributes, bearers of heritage’s interest. However, it is not possible to preserve everything, it is necessary to make a careful selection guided by relevant arguments. This article proposes a theoretical arrangement - inspired by the systemic approach, associated with concepts of network, nodality and centrality - able to provide analytical foundations essential to identify, in a railway network, the spatial structures and their relations, characterized as central places. Such structures, for being the most important to the functional dynamics of this network, they hold potential to preservation. It is a proposal, instigated by the imminent loss of railway structures, representative symbols of collective identities. The discussion focuses on the primitive railway system deployed in Recife, as part of the Northeast Railway Network in Brazil. This system polarized essential functions, conforming centralities in relation to the remaining network yards, and nodalities, compared to the established interrelationships with other networks that cover the territory. Therefore, they are Central Places.

title: The Right To The City And Production Space Between Discourses: The Fight For Signification Of Recovery Urban Environments

description: Abstract The aim of this study is analyse demands inherent to Pier Mauá’s urban space in Porto Alegre-RS through discursive structures, identifying elements and meanings that are present throughout urban space debates. For this, a research corpus was assembled containing 184 files, including: papers, interviews, images, videos, audios and documents that were analysed in order to better understand discourses from a social antagonism’s point of view. Under a post-structuralist perspective, Laclau and Mouffe’s Discourse Theory (TD) was used as it allows a socio-political analysis of society. Some auxiliary theories regarding the Right to the City from Henri Lefebvre was also considered as well as David Harvey’s Capitalist Production of Space. Following the tradition of TD studies, a retroductive methodology was performed. Our findings revealed a conflict between the hegemonic posture adopted by those who want to reshape Pier Mauá into a commercial and entrepreneurial area and those who, with a counter hegemonic posture, defend the maintenance and requalification of its area contemplating it as a public space ideal for leisure, culture and tourism. It was also possible to identify some equivalences considering Pier Mauá’s disputes around: the concept of City - on the one hand, related to mega structures, large enterprises and economic value towards progress and, on the other hand, participation, transparency, community and preservation through [r]existence strategies and other alternatives regarding the state of urban space being qualified for people and not for businesses.

title: Classification and grouping of Brazilian cities in heating and cooling degrees-day: 1960 to 2013

description: Abstract Degree-days is commonly used worldwide to estimate buildings energy consumption due to heating and / or cooling. However, in Brazil, there is no a technical standard calculation method and / or a degree-days zoning. The database is composed by the Climatological Norms and monthly averages of the Meteorological Database for Teaching and Research of INMET. These data allow to evaluate the evolution of the climatic condition of the cities. This paper presents a proposal for calculating degree-days applicable throughout the country, and a national zoning resulting from this classification. The heating (GDA) and cooling degree-days (GDR) were calculated based on the methodology described by Day (2006) and the temperatures were defined based on the adaptive model proposed by De Dear and Brager (2002). The grouping of cities by GDA and GDR was carried out by the cluster statistical procedure named K-means (Bussab et al., 1990) and then the statistical significance of the clusters generated was verified by the Test F. As a result, was obtained a ranking of 291 cities by number of GDA and GDR and the grouping of these seven clusters. The F test performed was significant for the proposed zoning. Finally, the zoning maps were produced in Brazilian cities by demand for heating or cooling.

title: Building an urban climatic analysis map for Belo Horizonte city, Brazil

description: Abstract The article proposes the adaptation and application of the German methodology for the construction of climatic maps for the city of Belo Horizonte. Land use data, geographic aspects and wind information were analyzed, producing different layers of thematic maps. Their combination allowed a definition of eight classes of climatopes, making an analytical urban climatic map. It was verified that the edges of the city at south, southeast and northeast, which the green areas are concentrated, have greater dynamic potential and lower thermal load, considered an advantage for nocturnal cooling. However, the densely built-up areas located in the city center have low nocturnal cooling capacity, due to thermal load storage and the lowest dynamic potential that favor the heating of the surfaces. Concerning to the distribution of climatope classes, it was observed that about half of the city area presents a negative thermal load and a good dynamic potential as an atmospheric response. This result indicates that the negative impact of the urban elements on the surface thermal load can be considered still low. The results are also the basis for urban planning recommendations in order to preserve and expand urban areas that can contribute to the improvement of the local climate of Belo Horizonte.

title: Evaluation of Road Signs conformity for improving road safety in urban Areas: a Case Study in Guimarães, Portugal

description: Abstract Road safety depends on the existence of an adequate network of signs and an effective management for proper conservation. Vertical traffic signs will only be effectively functional if they still provide adequate visibility and legibility. This paper presents a methodology to evaluate the level of conformity of traffic signs, in order to identify where to improve their functionality. The methodology is based on a multicriteria analysis, using two criteria and eight subcriteria that are related with signs physical and operational attributes. Their visibility was evaluated through a spatial analysis in a geographical information system, taking into account the braking and stopping distances. The intervention level is defined by four levels related with the necessity and urgency in restoring signs functionality. This methodology was applied in the city of Guimarães, Portugal. The results showed the usefulness of the methodology and revealed that more than half of the analyzed signs not fully complied with the norms, mainly due to the compactness of the urban structure e the presence of vegetation in streets. Since the braking and stopping distances of many signs are not adequate, it can be concluded that road users are exposed to risks and their safety can be threated.

title: Modeling Urban Sprawl Patterns of the Metropolitan Region of São Paulo based on Cellular Automata

description: Abstract The aim of this study was to model the urban sprawl patterns of the Metropolitan Region of São Paulo (MRSP) using a spatial modeling technique based on cellular automata (CA). Therefore, we used urban perimeter data related to the periods of 1881, 1905, 1929, 1949, 1974 and 2005 for the construction of four models. These models consider the combination of variables representing the initial state of the cell (urban or non-urban), the number of neighboring cells classified as urban and the number of neighboring cells classified as non-urban. A particular model, whose configuration considers the combination of the initial state of the cell with the number of neighboring cells classified as urban, had the best performance (i.e., 94% of correct predictions). Next, a land use forecast for 2030 was evaluated by this model, highlighting both infrastructure-oriented patterns of urban expansion and urban occupation processes in inappropriate areas. In summary, this study demonstrated that the method can serve as a tool in urban planning processes.

title: Planning and implementation of a selective waste collection program: using a geographical information system to calculate the routes

description: Abstract With the National Policy on Solid Waste it has become mandatory to implement selective waste collection programs and that such programs should be efficient. In both implementation and improvement of the selective waste collection programs that already exist, we must consider mainly three questions: who will act as the collection agent; which selective waste collection model will be used and how to effectively plan the collection routes. One way to optimize the collection routes is using a Geographic Information System (GIS). Therefore, in this paper it has been planned and implemented a selective waste collection in São Lourenço, Minas Gerais, using a GIS to calculate the routes. Today, there are two collection routes working, allowing the whole population of the city to be served by the selective waste collection program. Furthermore, it has been noticed that the door-to-door collection mode is not the optimal in the beginning of the implementation, and the awareness from the population was the main barrier in the implementation.
