Extensive urbanization around the world has resulted in the consumption of massive vegetated areas and natural resources. To this end, one strategy for urban development is to consolidate urban areas. In Balneário Camboriú/SC, Brazil, this trend has transformed the city into a vertical built-up area on its coastal strip, accommodating a large amount of buildings both in terms of quantity and number of floors. This research aims to quantify the thermo-hygrometric fluctuation on the waterfront of Balneário Camboriú, in negative radiation balance. To acquire the data on air temperature (Ta) and relative humidity (RH), two mobile transects and measuring at two fixed points were made in a situation of negative radiation balance on 26 August 2019, in the winter period of the Southern Hemisphere. The collection work began at 06:00:00 a.m. (before sunrise, the peak of the negative radiation balance), on Atlântica Avenue (waterfront) and Brasil Avenue (parallel to the waterfront). It was verified that the Ta varied from 16.0 °C to 19.0 °C, and the RH remained over 80% during the entire route. At the meteorological shelters, the temperature presented a variation from 14.4 °C to 17.7 °C, and the RH ranged from 79.6% to 91.3% between the two points. The spatial variability in the Ta and RH along the paths travelled and at the fixed points is directly related to the land cover, represented especially by the buildings’ verticalization and data collection time.

Over the coming years, developments of large urban areas are expected, many of them on plots where soil conditions may not be the most suitable for building. This is the case of plots that previously have been used for dumping anthropic fill deposits. The term anthropic fill included a large variety of materials, all of them related with human activity; but this paper is mainly focused on natural materials extracted from nearby excavations or construction debris that form non-contaminated lands. In a review of literature related to risks, it is observed that in the last 10 years there have been abundant investigations to determine vulnerability in urban areas. However, the risks derived from the presence of anthropic landfills have generally been overlooked. For this reason, there is a real need to quantify construction vulnerability in areas settled on anthropic landfills. A methodology, up to now unknown, must be created to estimate and extrapolate it to any part of the world. The aim is to avoid the likelihood of pathologies appearing in urban areas. Hence, and to address this lack of knowledge, an Integrated Evaluation Model has been developed. Its purpose is to quantify, simply but effectively, the construction vulnerability index in already consolidated areas of historic landfills. The proposed model has been validated in a very popular district of the city of Madrid. Its surface, the number of buildings affected and population involved make it truly representative.

The Postponement

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.

Public spaces are designed and managed in many different ways. In Hanoi, after the Doi moi policy in 1986, the transfer of the public spaces creation at the neighborhood-level to the private sector has prospered na-ture of public and added a large amount of public space for the city, directly impacting on citizen's daily life, creating a new trend, new concept of public spaces. This article looks forward to understanding the public spaces-making and operating in KDTMs (Khu Do Thi Moi - new urban areas) in Hanoi to answer the question of whether ‘socialization’/privatization of these public spaces will put an end to the urban public or the new means of public-making trend. Based on the comparison and literature review of studies in the world on public spaces privatization with domestic studies to see the differences in the Vietnamese context leading to differences in definitions and roles and the concept of public spaces in KDTMs of Hanoi. Through adducing and analyzing practical cases, the article also mentions the trends, the issues, the ways and the technologies of public-making and public-spaces-making in KDTMs of Hanoi. Win/loss and the relationship of the three most important influential actors in this process (municipality, KDTM owners, inhabitants/citizens) is also considered to reconceptualize the public spaces of KDTMs in Hanoi.

The pandemic of coronavirus disease (COVID-19) led to the need for drastic control measures around the world to reduce the impact on the health of the population. The confinement of people in their homes resulted in a significant reduction in human activity at every level (economic, social, industrial, etc.), which was reflected in a decrease in environmental pollution levels. Studying the evolution of parameters, such as the level of environmental noise caused by vehicle traffic in urban environments, makes it possible to assess the impact of this type of measure. This paper presents a case study of the acoustic situation in Cáceres (Spain) during the restriction period by means of long-term acoustic measurements at various points of the city.

The objective of the present study is to examine the extent to which social ventures are able to increase the “smartness” of cities. To achieve this goal, we adopt a qualitative approach using a case study method to obtain valuable insights about different characteristics and strategies of Cais (a non-profit association dedicated to helping disadvantaged people in urban areas). Through our analysis of Cais's activities, we assess whether its social interventions match the dimensions proposed by Giffinger et al. (2007) to rank smart cities' performance; specifically, it has smart: economy, people, governance, mobility, environment, and living. The research shows that the action pursued comprises elements from all the above-mentioned dimensions. Further, the analysis reveals that Cais reinforces the smartness of the city in which it acts (in terms of attributes such as living, economy, people, and environment).

The cities are expanding rapidly all over the world. India has also experienced this phenomenon and has continued the pace of growth. The recent trends in spatial growth of the cities are a new phenomenon in Indian urban landscape. The cities in India are witnessing development with the help of private developers for the last couple of decades. Being private properties these are by nature of exercising control have gates and boundaries. In scholarly literature these are called as Gated Community/Gated Development. Authors have argued them from various perspectives of anthropology, law, management and sociology etc. but very little has been discussed about their planning and morphology. Although, the rise of Gated Development is majorly attributed to the sense of fear and need for security, yet architects and urban designers, and even sociologist stress upon other methods to make the neighbourhoods secured. Hence the security aspects are not made part of the research here. The aspects of how these gated development impacts the perception of neighbourhood by residents is not touched upon. The paper discusses the distinction between the gated and non-gated neighbourhoods and also how residents perceive their neighbourhoods at large. For explaining this phenomenon, three neighbourhoods in the city of Gurugram in Haryana state in India have been identified as case study. These are identified on the basis of different morphological images that are identified. Space syntax and space cognition through sketch mapping is used for the analysis of the three neighbourhoods. The paper suggest that the continuity and connectivity of any spatial configuration is of utmost importance to make neighbourhood environment worthy of living life more socially connected.

Thomas Friedman (2005) argumenta que a expansão do comércio, a internacionalização das firmas, o crescimento acelerado do processo de outsourcing e a possibilidade de conexão em redes a custos cada vez mais baixos estão criando um “mundo plano”: um campo competitivo de condições homogêneas de concorrência no qual os indivíduos têm maior poder e melhores condições de vida. Este artigo desafia essa visão do mundo, argumentando que embora a globalização traga mudanças, oportunidades e desafios, nem todos os territórios têm a mesma capacidade de maximizar os benefícios e as oportunidades e de minimizaras ameaças circundantes. Numerosas forças estão se fundindo no sentido de provocar a emergência de “montanhas” urbanas, onde a riqueza, a atividade econômica e a capacidade de inovação se aglomeram. Estas forças “tectônicas” incluem fatores como a inovação, os transbordamentos, os encadeamentos para trás e para frente nas cadeias produtivas, a dinâmica de especialização versus diversificação, o capital social e comunitário e, por último, mas não menos importante, o “buzz” da cidade. As interações destas forças na proximidade geográfica das grandes áreas urbanas dão forma a uma geografia muito mais complexa da economia mundial e permitem a ascensão de novos players econômicos. Mas esta geografia, ao contrário de ser plana, é repleta de montanhas, em que as grandes aglomerações urbanas representam os picos mais altos. A maioria da população mundial, ao contrário de ter maior poder, permanece mal preparada para encarar estes desafios. Palavras-chave: progresso tecnológico; nova geografia econômica; vantagem competitiva. Abstract: Thomas Friedman (2005) argues that the expansion of trade, the internationalization of firms, the galloping process of outsourcing, and the possibility of networking at increasingly low prices is creating a ‘flat world’: a level playing field where individuals are empowered and better off. This paper challenges this view of the world by arguing that although globalization implies changes, opportunities, and threats, not all territories have the same capacity to maximize the benefits and opportunities and minimize the threats at hand. Numerous forces are coalescing in order to provoke the emergence of urban “mountains” where wealth, economic activity, and innovative capacity agglomerate. These “tectonic” forces include factors such as innovation, spill overs, backward and forward linkages, specialisation vs. diversification dynamics, community and social capital, and, last but not least, the buzz of the city. The interactions of these forces in the close geographical proximity of large urban areas give shape to a much more complex geography of the world economy and allows for new economic players to emerge. But this geography, rather than flat, is full of mountains, with large urban agglomerations representing the highest peaks. The majority of the world population, far from being empowered, remains ill-prepared to face these challenges. Keywords: technological progress; new economic geography; competitive advantage.

From the urban territorial expansion, the natural environment wastransformed resulting in changes in the elements of the climate, such as the temperature and relative humidity of the air. Thus, the present study aimedto analyze the thermal and hygrometric field in the Santa Helena neighborhood in comparison to the nearby rural environment in the city of Osvaldo Cruz/SP. For this, fixed points of data collection of these two elements of the climate were used, relating them with the different use and occupation of the landand the characteristics of therelief. The results showed changes in the local atmosphere of Santa Helena, with heat islands and dry islands recorded at 15h, with intensities of up to +4,2ºC and -3,8% respectively. However, at 0h, fresh islandsand wetisland were diagnosed,with maximum values of -4,4ºC and +21,9%respectively.
