Urban air quality changes resulting from the lockdown period due to the COVID-19 pandemic.

This work aims to quantify potential pollution level changes in an urban environment (Madrid city, Spain) located in South Europe due to the lockdown measures for preventing the SARS-CoV-2 transmission. Polluting 11 species commonly monitored in urban zones were attended. Except for O3, a prompt target pollutant levels abatement was reached, intensely when implanted stricter measures and moderately along those measures' relaxing period. In the case of TH and CH4, it is evidenced a progressive diminution over the lockdown period. While the highest decreasing average changes relapsed on NOx (NO2: - 40.0% and NO: - 33.3%) and VOCs (C7H8: - 36.3% and C6H6: - 32.8%), followed by SO2 (- 27.0%), PM10 (- 19.7%), CO (- 16.6%), CH4 (- 14.7%), TH (- 11.6%) and PM2.5 (- 10.1%), the O3 level slightly raised 0.4%. These changes were consistently dependent on the measurement station location, emphasizing urban background zones for SO2, CO, C6H6, C7H8, TH and CH4, suburban zones for PM2.5 and O3, urban traffic sites for NO and PM10, and keeping variations reasonably similar at all the stations in the case of NO2. Those pollution changes were not translated in variations on geospatial pattern, except for NO, O3 and SO2. Although the researched urban atmosphere improvement was not attributable to meteorological conditions' variations, it was in line with the decline in traffic intensity. The evidenced outcomes might offer valuable clues to air quality managers in urban environments regarding decision-making in favor of applying punctual severe measures for quickly and considerably relieving polluting high load occurred in urban environments.

Assessing Ecological and Socio-Economic Attributes in Sustainable Management of Solid Medical Waste in Urban Environment

Unreliable system of solid waste management has hindered performance of public health system in developing countries. This condition was exacerbated by the covid-19 pandemic which posed risk to healthcare staff and public that makes the management of medical waste worsening. This study seeks to analyze the existing conditions of community health centre solid medical waste management from ecological, economic and social aspects in Pekanbaru and to design a solid medical waste management model for community health centres in Pekanbaru by identifying and quantifying ecological and socio-economic attributes to help solid medical monitor waste. A mixed method approach is used in this study with inferential analysis. Data analysis was used to analyze the relationship of ecological, economic and social factors to the management of solid medical waste at community health centres in Pekanbaru. The analysis process included univariate and bivariate analysis using a computerized program. The findings show that monitoring through the waste monitoring application can help monitor waste management in community health centres. As an implication, a solid medical waste management model can be used and implemented to support sustainable solid medical waste management. © 2023 WITPress. All rights reserved.

Delineando modos cuidadosos de construir las ciudades post-COVID-19

This work recognizes the interdependence of cities with the natural environment whose effects, after an unbalanced relationship, range from extreme weather events to the spread of the COVID-19 virus. In this context, this research investigates the emergence of changes in urban daily practices that, from the pandemic, could build careful ways for the human and non-human life that form and transform cities. Everyday practices are framed and analyzed based on the ideas of posthumanism scholars;in particular, anti-essentialist eco-politicians such as Bruno Latour, Donna Haraway, Rosi Braidotti, Anna Tsing, Vinciane Despret, among others, who recognize the dialectical relationship between human settlements and nature. Through the application of digital surveys and semi-structured interviews in Mexican cities, seeds of changes in urban daily life are identified in three dimensions: to dilute the separation between nature and culture;to connect with the territories where we live and on which we depend;and to build attentive and careful links. Although the results do not yet enunciate drastic transformations, they do outline deep and significant changes that, if further explored, could contribute to forging the cities to come. © 2022 Universidad Nacional de Colombia.

Use of geospatial tools to predict the risk of contamination by SARS-CoV-2 in urban cemeteries.

Urban cemeteries are increasingly surrounded by areas of high residential density as urbanization continues world-wide. With increasing rates of mortality caused by the novel coronavirus, SARS-CoV-2, urban vertical cemeteries are experiencing interments at an unprecedented rate. Corpses interred in the 3rd to 5th layer of vertical urban cemeteries have the potential to contaminate large adjacent regions. The general objective of this manuscript is to analyze the reflectance of altimetry, normalized difference vegetation index (NDVI) and land surface temperature (LST) in the urban cemeteries and neighbouring areas of the City of Passo Fundo, Rio Grande do Sul, Brazil. It is assumed that the population residing in the vicinity of these cemeteries may be exposed to SARS-CoV-2 contamination through the displacement of microparticles carried by the wind as a corpse is placed in the burial niche or during the first several days of subsequent fluid and gas release through the process of decomposition. The reflectance analyses were performed utilizing Landsat 8 satellite images applied to altimetry, NDVI and LST, for hypothetical examination of possible displacement, transport and subsequent deposition of the SARS-CoV-2 virus. The results showed that two cemeteries within the city, cemeteries A and B could potentially transport SARS-CoV-2 of nanometric structure to neighboring residential areas through wind action. These two cemeteries are located at high relative altitudes in more densely populated regions of the city. The NDVI, which has been shown to control the proliferation of contaminants, proved to be insufficient in these areas, contributing to high LST values. Based on the results of this study, the formation and implementation of public policies that monitor urban cemeteries is suggested in areas that utilize vertical urban cemeteries in order to reduce the further spread of the SARS-CoV-2 virus.

New determinants of mental health: the role of noise pollution. A narrative review.

Urbanisation processes and anthropogenic actions led to a significant increase in pollution levels, with relevant consequences on global health. In particular, noise pollution demonstrated an association with cardiovascular, metabolic, and respiratory diseases. Furthermore, increasing evidence underlined the possible role of air and noise pollution in the development of psychiatric disorders. In this narrative review, evidence concerning the relationship between noise pollution and the emergence of psychiatric symptoms or psychiatric disorders is summarised. After the literature search process was completed, 40 papers were included in the present review. The exposure to road-, rail-, and air- traffic represented a risk factor for the emergence of affective disorders. This could also be mediated by the occurrence of circadian rhythms disturbances or by noise annoyance and noise sensitivity, both influencing psychological well-being and health-related quality of life. Fewer studies concentrated on special populations, particularly pregnant women and children, for whom noise pollution was confirmed as a risk factor for psychopathology. The better clarification of the complex interaction between noise pollution and mental health may help to identify subjects at risk and targeting specific prevention and intervention strategies in the urban environment.

Modelling Impact of High-Rise, High-Density Built Environment on COVID-19 Risks: Empirical Results from a Case Study of Two Chinese Cities.

Characteristics of the urban environment (e.g., building density and road network) can influence the spread and transmission of coronavirus disease 2019 (COVID-19) within cities, especially in high-density high-rise built environments. Therefore, it is necessary to identify the key attributes of high-density high-rise built environments to enhance modelling of the spread of COVID-19. To this end, case studies for testing attributes for modelling development were performed in two densely populated Chinese cities with high-rise, high-density built environments (Hong Kong and Shanghai).The investigated urban environmental features included 2D and 3D urban morphological indices (e.g., sky view factor, floor area ratio, frontal area density, height to width ratio, and building coverage ratio), socioeconomic and demographic attributes (e.g., population), and public service points-of-interest (e.g., bus stations and clinics). The modelling effects of 3D urban morphological features on the infection rate are notable in urban communities. As the spatial scale becomes larger, the modelling effect of 2D built environment factors (e.g., building coverage ratio) on the infection rate becomes more notable. The influence of several key factors (e.g., the building coverage ratio and population density) at different scales can be considered when modelling the infection risk in urban communities. The findings of this study clarify how attributes of built environments can be applied to predict the spread of infectious diseases. This knowledge can be used to develop effective planning strategies to prevent and control epidemics and ensure healthy cities.

Outlining careful ways to build post-COVID-19 cities

Context Matters-Child Growth within a Constrained Socio-Economic Environment.

Communities in major cities in developing countries may experience economic vulnerability, which has detrimental consequences for maternal and child health. This study investigated individual-, household-, and community-level factors associated with child growth and resilience of early-grade learners aged 6 to 8 years. Demographic characteristics, depression scale, child wellbeing, and anthropometric measurements were collected on a sample of 162 caregiver-child pairs (children 46% female) who receive the child support grant (cash transfer programme) from five low-income urban communities in the City of Johannesburg, South Africa. Height and weight were converted to z-scores using the WHO Anthroplus software. Multiple linear regression was used to assess factors associated with child health outcomes and multi-level regression to account for community-level factors. Higher income vulnerability was associated with lower weight- and height-for-age z-scores (WAZ and HAZ). Not completing secondary schooling and higher household size were associated with lower HAZ but higher BAZ. Child male sex and caregiver with depression were associated with lower child resilience. Caregiver's level of schooling and household size remained independent predictors of child growth, while the caregiver's mental health status independently predicted child resilience. Thus, notwithstanding systemic constraints, there may be modifiable drivers that can help in developing targeted intervention.

Preliminary Results of COVID-19 Restriction Measures on the Air Pollution Levels in the City Center of Athens, Greece

COVID-19 is evolving into one of the worst pandemics in recent history. The lockdown measures implemented worldwide to slow the spread of the COVID-19 pandemic have caused an unprecedented reduction in global economic activity. Strict lockdown measures came into force in Greece from March 23th 2020. This study aims to assess the changes in air pollution levels during the restriction measures in Athens, the city with the most COVID-19 cases in the whole country. Measurements in a central location during the lockdown (24/03/2020 -07/04/2020) were compared with levels during the pre-lockdown (19/02/2020 -11/03/2020) period. Urban air pollution markedly decreased but with substantial differences among pollutants. The most significant impact during the lockdown period was observed for the concentrations of carbon monoxide (CO) and nitrogen oxides (NOx) with reduction percentages of -47% and - 35%, respectively, compared to the pre-lockdown period. These air pollutants are mainly related to traffic emissions. A lower reduction was recorded for coarse particulate matters (PMio) (-24%), probably due to the existence of other local sources of emission along with secondary formation. Nevertheless, this result must be further examined in order to be interpreted. Additionally, meteorological parameters such as wind speed found to play a key role on the results as most air pollutants were negatively correlated with higher air velocities. The scope of this study is to provide short term air quality results to the existing literature, in order to enhance decision making on life quality improvement in respect to the urban environment. © 2022 American Institute of Physics Inc..

Creative Clusters as Transformational Ways of the Urban Environment and a Tool for Enhancing the City’s Tourist Attractiveness (On the Example of St. Petersburg).

The article examines the specifics of formation and functioning of creative clusters as a creative economy pillar. The interpretation of the creative cluster as “third place” in the concept of the American sociologist R. Oldenburg is presented. The Creative Cluster is seen as the hub of the city's business and cultural life. The most successful and actively developing clusters in St Petersburg include “Novaya Gollandiya”, “Sevkabel Port”, “Bertgold Centre” and “Nikolskie Ryady”. The role of these locations in preserving historical and cultural heritage, enhancing the urban environment and developing the tourist potential of the city is presented. The characteristics of cluster activities under the constraints imposed by the coronavirus pandemic are examined. The directions of state support and prospects for the development of creative clusters in the Russian Federation are outlined.

Urban Aerobiome and Effects on Human Health: A Systematic Review and Missing Evidence

Urban air pollutants are a major public health concern and include biological matters which composes about 25% of the atmospheric aerosol particles. Airborne microorganisms were traditionally characterized by culture-based methods recognizing just 1.5–15.3% of the total bacterial diversity that was evaluable by genome signature in the air environment (aerobiome). Despite the large number of exposed people, urban aerobiomes are still weakly described even if recently advanced literature has been published. This paper aims to systematically review the state of knowledge on the urban aerobiome and human health effects. A total of 24 papers that used next generation sequencing (NGS) techniques for characterization and comprised a seasonal analysis have been included. A core of Proteobacteria, Actinobacteria, Firmicutes, and Bacteroides and various factors that influenced the community structure were detected. Heterogenic methods and results were reported, for both sampling and aerobiome diversity analysis, highlighting the necessity of in-depth and homogenized assessment thus reducing the risk of bias. The aerobiome can include threats for human health, such as pathogens and resistome spreading;however, its diversity seems to be protective for human health and reduced by high levels of air pollution. Evidence of the urban aerobiome effects on human health need to be filled up quickly for urban public health purposes.

A spatial model for assessment of urban vulnerability in the light of the UN New Urban Agenda guidelines: case study of Assiut City, Egypt.

Most cities in developing countries suffer environmental degradation caused by the growth of unplanned areas that sprawl in the cities. In the current paper, we attempted to integrate a set of selected UN-based urban indicators based on the New Urban Agenda (NUA) within a GIS framework to observe and assess some aspects of urban vulnerability among city districts based on deprivation. The vulnerability map for the districts in Assiut City was created through a spatial multicriteria evaluation model. Thirteen sub-indicators related to shelter, social environmental and economic situations have been assessed in the model using standardization, weighting and aggregation methods. Results revealed that: districts, namely, El Thaltha, El Owla, El Thania, and El Rabaa are most vulnerable in most scenarios, while districts, namely, El Sheyakha El Sabaa, and El Sadsa, El-Walidya El Qiblia and El-Hamra El Thania are among the least vulnerable zones. Results also revealed that vulnerable districts encompass the highest percentage of slums, highest density of population, highest rates for urban growth and poor connection to services. Eventually, we assume that the most vulnerable zones in the city are under the highest risk of airborne diseases including COVID-19 epidemic. Eventually, a subset of selected urban vulnerability indicators that could be triggering the spread of the pandemic was chosen for another spatial multcriteria model to delineate city zones under risk. The result revealed that expected high-risk areas exist in the south-west of the city and include El Thaltha, El Owla, El Thania and El Rabaa districts, while the least risk district is El-Walydia El-Qeblia. The applied methodology and its outputs could support decision makers in reviewing priorities, setting contingency plans, allocation of funds and raising resilience among the city districts.

Impacts of COVID-19 on bike-sharing usages in Seoul, South Korea.

The COVID-19 pandemic and social distancing restrictions have had a significant impact on urban mobility. As micro mobility offers less contact with other people, docked or dockless e-scooters and bike-sharing have emerged as alternative urban mobility solutions. However, little empirical research has been conducted to investigate how COVID-19 might affect micro mobility usage, especially in a major Asian city. This research aims to study how COVID-19 and other related factors have affected bike-sharing ridership in Seoul, South Korea. Using detailed urban telecommunication data, this study explored the spatial-temporal patterns of a docked bike-sharing system in Seoul. Stepwise negative binomial panel regressions were conducted to find out how COVID-19 and various built environments might affect bike-sharing ridership in the city. Our results showed that open space areas and green infrastructure had statistically significant positive impacts on bike-sharing usage. Compared to registered population factors, real-time telecommunication floating population had a significant positive relationship with both bike trip count and trip duration. The model showed that telecommunication floating population has a significant positive impact on bike-sharing trip counts and trip duration. These findings could offer useful guidelines for emerging shared mobility planning during and after the COVID-19 pandemic.

Social Vulnerability: understanding the territory to confront COVID-19

This work aimed to evaluate social vulnerability based on popu-lation characteristics as a means to indicate the possible intra-ur-ban spaces with greater chances of dispersion and contagion by COVID-19. Based on variables that explain social characteristics and increase the vulnerability of individuals, information from IBGE was selected, treated by factor analysis and mapped, accord-ing to the adaptation of the methodology developed by the Centre for Social Studies in Coimbra. The scale of coverage chosen was that of census sectors, from three municipalities in the state of Rio Grande do Sul/Brazil. The analysis resulted in 21 variables that make it possible to classify five dimensions of the vulnerability of the populations, indicating the places where actions to prevent contagion should be more incisive, given the population character-istics, and the vulnerability of urban peripheries was evidenced. The grouping of information expressed social dimensions that de-note aspects auxiliary to understanding the territory and social vul-nerability on a local scale. The methodology demonstrated can be easily adopted in different scales and regions of Brazil, and also in other countries. This study will make it possible to make decisions aimed at avoiding contagion, and to subsidize with information the elaboration of plans for the gradual resumption of economic and social activities.

The Role of Urban Environment Design on Health During the COVID-19 Pandemic: A Scoping Review.

The COVID-19 pandemic has had a significant impact on the ways and times of living and using urban spaces, specifically referring to the dimension of daily life. The restrictive measures introduced during the lockdown periods have necessarily led to a re-evaluation of proximity scale bringing particularly attention to issues relating to public transport and mobility and to the quality and distribution of open public spaces. This scoping review explores the relationship between the urban environment design and health referring to the constraints imposed by the COVID-19 pandemic in the period from 2020 to 2021, with two main objectives: (i) to investigate the recurring urban design topics and issues related to the spatial and social needs stressed by the emergency; (ii) to identify the urban design measures both experienced during the health emergency and proposed in view of a post-COVID urban and territorial planning as they are considered impactful on health promotion. The search strategy was based on a set of keywords searched in two electronic databases which allowed the identification of a total of 1,135 contributions. After defining the eligibility criteria, we proceeded to the screening process concluded with the inclusion of 19 studies. The analysis of the contributions led to the systematization of six main urban topics-and to the corresponding spatial requirements and project proposals-highlighted as relevant and supportive in terms of the promotion of inhabitant's public health: (i) transport, mobility and accessibility; (ii) green and outdoor spaces; (iii) public and pedestrians' spaces; (iv) care services and health network; (v) communications; (vi) public and business services. The resulting framework is useful for guiding healthy city planning toward public policies, tools, regulations, urban measures, and emergency contrast provisions, that contribute to increasing the effectiveness in terms of safety and well-being.

Investigating the role of the urban environment in controlling pandemics transmission: Lessons from history

It is known throughout history that vaccines are the best solutions to mitigate the effects of pandemics and control their transmission. However, before vaccines were developed, this process was being accomplished using a range of measures and solutions, some of which were related to the urban environment. In this regard, this study investigates the role of the urban environment in controlling pandemics transmission. The study finds that the urban environment can control pandemics transmission through its morphology, urban infrastructure, and buildings, in addition to the expansion outside the existing urban agglomerations. Moreover, it can help the individuals to fight the infection off in case of being infected by giving them the potentials to strengthen their immune system. The findings of this study can direct the viewpoint of urban planners and designers towards the role of the urban environment in maintaining public health. It can also highlight controlling current and future pandemics through the planning and design processes.

Impact of the Pandemic on the Sustainable Development of Metropolitan Residential Complexes

The article reviews sustainable architecture formation principles of the residential complex in Russia in the post-covid period. The situation has changed in three sociological coordinates: the usual way of life has been destroyed, the quality of life has been reduced with the threat of its radical fall, goals have changed and the possibility of long-term planning is lost. The authors conduct an analysis of the post-covid situation and derive new demands of citizens. It's about the cult of productivity has been replaced by a cult of health care, both physical and mental. Consequently, all vital structures should be within walking distance: centers for first aid and diagnostics, pharmacies, sports grounds and fitness centers. When designing residential complexes, emphasis should be placed on landscaping and improvement. New is the organization of spaces for urban agriculture. There is a return not to the pre-covid reality from which the population was expelled by the virus, but to a new state called the “new normal”—a life different from the previous one. The article reveals the concept and formulates the basic principles of the architectural design of quarter residential buildings, typical for large cities in different countries in modern conditions. The authors of this article confirm the need to unite the infrastructure in the space of the residential complex, which will ensure the satisfaction of the needs of all residents living in the residential unit. The new practice of urban planning implies the ability to live, work and spend leisure time within the same accessible territory. Architecture contributes to both the physical and emotional recovery of a person. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Spatiotemporal representativeness of air pollution monitoring in Dublin, Ireland.

The importance of selecting appropriate air pollution monitoring sites in a city is vital for accurately reporting air quality, enhancing the quality of high-resolution modelling and informing policy to implement measures to deliver cleaner air in the urban environment. COVID-19 restrictions impacted air quality in urban centres worldwide as reduced mobility led to changes in traffic-related air pollution (TRAP). As such, it offered a unique dataset to examine the spatial and temporal variations in air quality between monitoring stations in Dublin, Ireland. Firstly, an analysis of mobility data showed reductions across almost all sectors after COVID-19 restrictions came into place, which was expected to lower TRAP. In addition, similar changes in air quality were evident to other cities around the world: reductions in fine particulate matter (PM2.5) and nitrogen dioxide (NO2) concentrations and an increase in ozone (O3) concentrations. Average daily and diurnal concentrations for these three pollutants presented more statistically significant spatial and temporal changes during COVID-19 restrictions at monitoring sites with urban or traffic classifications than suburban background sites. Furthermore, substantial reductions in the range of average hourly pollutant concentrations were observed, 79% for PM2.5 and 75% for NO2, with a modest 24% reduction for O3. Correlation analysis of air pollution between monitoring sites and years demonstrated an improvement in the R2 for NO2 concentrations only, suggesting that spatiotemporal homogeneity was most notable for this TRAP due to mobility restrictions during COVID-19. The spatiotemporal representativeness of monitoring stations across the city will change with greener transport, and air quality during COVID-19 can provide a benchmark to support the introduction of new policies for cleaner air.

Air quality fluctuation monitoring and statistical data analysis during COVID-19 pandemic in Siliguri city, India

Introduction: Worldwide coronavirus created is a major problem for human health, food security, economy and many more. World Health Organisation (WHO) named this virus COVID-19. This virus is first detected in Wuhan, China in December 2019 and after that, it’s spreading over the world. Lockdown is healing the environmental condition because major Indian metropolitan cities are recovered from different pollutants. This study is to identify the air quality trend before, during and after the lockdown in Siliguri city, the third-largest city of West Bengal and this city is also a commercial and transportation hub.Materials and methods: The air quality data have been derived from West Bengal Pollution Control Board (WBPCB) and proceed in MS-Office and ArcGIS 10.4. The air pollutant and week air quality data have been used for monitoring the environmental situation. Results: In this study, results show that around 70%-90% of air quality is increased during strict lockdown but again air quality is decreased after lockdown gradually. The weekly air quality graph significantly changes during lockdown but after lockdown, the graph was increased. The highest air quality shows 347 before lockdown but during lockdown it’s decreased 25 on 23-24 May 2020. After lockdown public transport, industrial area and small scale industries are reopened and again the air quality increased. The highest air quality shows 353 on 14 January 2021 during unlock 8.0. Conclusion: This pandemic taught how anthropogenic activates, like urbanization, population pressure and industrial works were endangering the environment and some caution is essential for future livelihood. © 2021 Tehran University of Medical Sciences.
