Abstract:
This article proposes to analyze the urban phenomena resulting from the implementation of horizontal gated communities, located in the municipality of Rondonópolis-MT. Its high commercial value, characterized as speculative, demonstrates the sale of the city as a commodity in the consolidated soil of the municipality. The socioeconomic development of/in cities occurs unevenly through urban interventions, resulting in socio-spatial and socio-economic inequalities produced and reproduced spatially. Thus, understanding the urban structure resulting from real estate speculation as appropriation of public space, segregation, gentrification, spreading and the fortified enclosure existing in the city's gated communitiess, which makes evident the socio-spatial and socio-economic contradictions and disparities in a medium-sized city with strong support from agribusiness in the region.

Abstract:
This article approaches pandemic’ influence in architecture and urbanism and tries to answer the question: what are the main subjects that have been discussed by architects and urbanists in the news when they try to understand the relationship between habitation and pandemic? The article’s purpose is to reveal an overview of the main reflexions running on specialized websites, such as searches at ArchDaily Brazil, about how Covid-19 affects architecture and urbanism. It’s a qualitative research with an exploratory character and a sistematic literature review with an extensive content analysis. In the end, some topics try to bring possible answers for the distancing and social isolation repercussions in residential architecture and cities.

Abstract:
Sustainability in large-scale food production is one of humanity's greatest contemporary challenges. Today’s society is totally dependent on agricultural fields. In face of the increasing environmental and food crisis in the world, it is necessary to improve ways of promote sustainable agriculture. Conventional agriculture has proved to be predatory to the environment and maleficent to human health due to the intensive use of agrochemicals, and also inefficient to supply with quality and safety the whole urban population. Therefore, urban agroecology has become a tendency. The study presented here investigated a community garden of the West Zone of São Paulo City, organically grown in the Previdência Municipal Park, which is an intensely urbanized area. Observations were carried out in loco, plus interviews with the responsible for the community garden, and compilation of relevant literature, focusing on the importance of horticulture, practical difficulties in the community involved in the project, benefits to society, and the role in urban sustainability. Horticulturists’ social aspects, involvement of the regulars, and adopted cultivation techniques were also investigated. The challenges of urban agriculture projects reported in the literature were identified, so as to define the best cultivation strategies to be adopted in the community garden. The main results pointed to benefits to food and nutrition safety, interpersonal involvement, and environmental education; the main challenges consist of social leaderships, technical-scientific knowledge regarding productivity of organic cultivars, and planning aiming the continuity of the projects. Relevant benefits can be obtained from the implementation of urban garden projects, contemplating some of the Objectives of Sustainable Development that are related not only to sustainable agriculture, but also to the sustainability of cities and communities. KEYWORDS: Urban Agriculture. Food Safety. Urban Parks. Sustainability.

Abstract:
Urban development is marked by challenges associated with energy demands at a variety of levels, as well as the need of an efficient solid waste management. In the next 30 years an increase of the world’s population and of this population in urban areas is predicted, turning such dilemma a reality. In this context, organic waste can be recycled as a clean, renewable energy resource by means of biogas, which is a sub-product of anaerobic digestion and which can be converted into electric and thermal energy by burning, and therefore be used in heating and as fuel. Biogas is produced in biodigesters, which consist of an airtight chamber with compartments for the substrate inlet and the final product outlet. From a bibliographic research, the present study investigates the main models of biodigesters used in Europe, Asia, Africa and South America, in order to present an up-to-date scenario of the application of such equipment in the context of intelligent cities. The results indicate contrasting biodigester installations among the continents. Whereas Europe relies on high-technology models, in Africa, for example, biodigesters are usually built with basic materials, which make biogas production inefficient. Similarly to other energy sources and waste management models, the countries with better infrastructure and resources can better benefit from the use of biodigesters, thus improving the quality of life, whereas poorer countries cannot totally exploit the same productivity potential.

Abstract:
The theme of this article is immobility, in essence. When substantially all of humanity is forced to either reduce its usual flows or systematize them into "essential" and "non-essential," the Municipality of Juiz de Fora started to observe one of its most traditional public spaces becoming a source of infection and consequently a symbol of necessary containment. Under those circumstances, this study aimed to analyze the mobility restrictions in favor of public health plus the efforts of the local government through a bibliographic review about the specific set of the Halfeld Park (Parque Halfeld). Primary sources highlight the emerging need to guarantee the best conditions for public spaces in the current context (the “new normal”) in any city. In effect, this work contributes to the discussion about rethinking cities, as well as providing data that prove faulty urban planning and management when dealing with this crisis: palliative actions are not enough.

Abstract:
This work aims to use the Normalized Difference Built-up Land Index and Built-up Index to evaluate the urban perimeters of Maringá and Sarandi, Paraná. In order to identify if there was a spatial difference in the built areas. The methodological procedures were based on the spatial analysis of urban perimeters, generation of each index, interaction between index and environment. In the results and discussions, the values obtained by the indexes are approached and the localities with higher and lower values are scored, with possible causes denoted, as well as the relationship with the literature. It was concluded that Maringá and Sarandi, Paraná, have urban density in an advanced stage of urban consolidation, in the perspective of soil waterproofing, since the indexes worked do not measure vertical densities, but horizontal ones.

Abstract:
The growing world’s population demands large electric energy production for the functioning and development of the modern society. With the increase of energy consumption and environmental changes caused by these processes, it is fundamental that public and private sectors search for alternative energy sources, which must be not only sustainable but also efficient for the development of their activities. In this context, renewable energy causes less impact to the environment, mitigating the emission of gases that contribute to the greenhouse effect. Among the main renewable energy sources, the photovoltaic solar energy stands out, with the advantage of being installed in small spaces and requiring minimum changes in such spaces. The photovoltaic solar system is one of the alternative energy options that have received considerable investments worldwide, because solar radiation is an abundant and inexhaustible energy source incident on the Earth’s surface. Large buildings, such as hospitals, despite being essential to well-being and health care, present a great polluting potential, in the sense that they may cause indirect hazards to the environment, due to the amount of energy that they need to perform a series of procedures. The present study aims to present the main projects of photovoltaic solar energy implementation that aimed at energy efficiency in hospitals. The study is based on bibliographic research and adopted a qualitative approach to assess study cases in Brazil and in some other countries. Among the main results, the projects implemented in hospitals in Europe, Africa and Brazil are highlighted, because of the attested efficiency reached after the implementation of photovoltaic solar panels, minimizing the amount of CO2 launched in the atmosphere and achieving energy and financial savings.

Abstract:
Horizontal gated communities (HCGs) affect the dynamics of cities, as they are obstacles to mobility, integration and democratic use of public space. In this work, we investigate the negative impacts caused by these ventures and propose mitigation measures from the perspective of urban planning. This was based on bibliographic materials and a collection of interventions found in the literature, which led to a proposal of intervention on the walls of an HCG located in the Brazilian city of Engenheiro Coelho/SP. The focus of the proposed intervention was the outsourcing of part of the public green areas, visual permeability and improvement of access. The intervention proposals aimed at urban democratization and the resilience of communities impacted by this type of real estate development, in addition to restoring the right to enjoy the city and minimizing socio-spatial segregation, ensuring access to public areas and greater compliance with urban mobility policies.

Abstract:
This study aimed to evaluate environmental noise around a public hospital in the city of Sorocaba, Brazil, before and during the COVID-19 pandemic. The measurements were performed in triplicate, on weekdays, at three points around the hospital during the night, and followed the guidelines of the NBR 10151/2019 standard. At the same measurement points, the manual counting of light vehicles, heavy goods, and motorcycles was performed. The equipment used was the BK 2260 analyzer and the BK 4231 calibrator. For statistical analysis, data normality was verified through the Shapiro-Wilk test and, later, the differences in sound levels before and during the pandemic through the paired t-test. The correlation between sound levels and the number of vehicles was verified by Spearman's correlation. The level of significance adopted was α=0.05. There was a significant reduction in the movement of light and heavy vehicles during the pandemic and less reduction for motorcycles. It was found that P1 was the noisiest point and the one with the lowest variation in dB(A) during the pandemic, associated with higher speed and greater circulation of vehicles. Although there is a strong correlation between the number of vehicles and sound levels, statistically there was no significant difference. It is concluded with this work that there was a reduction in environmental noise around the hospital during the pandemic and that other factors should be taken into account, such as the speed of vehicles.

Abstract:
The COVID - 19 virus emerged in China and has spread to all areas in Brazil, including the Amazon River Delta, where the population lacks essential services. Thus, this article aims to characterize the dispersion of COVID-19 in the small municipalities of the Amazon River Delta, which have fewer than 50,000 inhabitants, detailing the towns' situation. Covid-19 data provided by the health departments of the states of Amapá and Pará, and census data from the IBGE, were used to create maps of the disease for the Delta's municipalities. The virus circulated rapidly to the smallest localities, where the health service and sanitary conditions are precarious, leading to a severe contamination rate. Together with other known aspects, this is yet another opportunity to show the regional needs and the importance of public policies for this population.
