Due to the COVID-19 pandemic, there are series of negative economic consequences, however, in limiting mobility and reducing the number of vehicles, positive effects can also be observed, i.e., improvement of air quality. The paper presents an analysis of air quality measured by concentrations of NO2, NOx and PM2.5 during the most restrictive lockdown from 10 March to 31 May 2020 on the case of Wrocław. The results were compared with the reference period—2016–2019. A significant reduction in traffic volume was identified, on average by 26.3%. The greatest reduction in the concentration of NO2 and NOx was recorded at the station farthest from the city center, characterized by the lowest concentrations: 20.1% and 22.4%. Lower reduction in the average concentrations of NO2 and NOx was recorded at the municipal station (7.9% and 7.7%) and the communication station (6.7% and 10.2%). Concentrations of PMs in 2020 were on average 15% and 13.4% lower than in the reference period for the traffic station and the background station. The long-term impact of the lockdown on air quality was also examined. The analysis of the concentrations of the pollutants throughout 2020, and in the analyzed period of 2021, indicated that the reduction of concentrations and the improvement in air quality caused by the restrictions should be considered as a temporary anomaly, without affecting long-term changes and trends.

Due to irregular and uncontrolled expansion of cities in developing countries, currently operational landfill sites cannot be used in the long-term, as people will be living in proximity to these sites and be exposed to unhygienic circumstances. Hence, this study aims at proposing an integrated approach for determining suitable locations for landfills while considering their physical expansion. The proposed approach utilizes the fuzzy analytical hierarchy process (FAHP) to weigh the sets of identified landfill location criteria. Furthermore, the weighted linear combination (WLC) approach was applied for the elicitation of the proper primary locations. Finally, the support vector machine (SVM) and cellular automation-based Markov chain method were used to predict urban growth. To demonstrate the applicability of the developed approach, it was applied to a case study, namely the city of Mashhad in Iran, where suitable sites for landfills were identified considering the urban growth in different geographical directions for this city by 2048. The proposed approach could be of use for policymakers, urban planners, and other decision-makers to minimize uncertainty arising from long-term resource allocation.

Purpose The purpose of this paper is to explore how culture, including traditions and social structures, can influence resilience and how culturally sensitive relief operations can put affected people and their context at the core of any interventions. Design/methodology/approach A case study of the Mt Sinabung volcano area in Indonesia was undertaken. As part of the case study, an analysis of interventions was conducted, which was complemented by semi-structured interviews with Karo cultural experts and humanitarian organisations. Findings Culture influences the manner in which the Karo people react to volcano eruptions with varying implications for recovery. In addition, relief organisations which understand people’s actions through a cultural lens have better managed to tailor programs with long-term impact, thereby avoiding aid dependency. Practical implications Practical examples of disaster management activities that adequately account for the beneficiaries’ way of living prior to the eruptions are provided. Aid actors are provided with guidance concerning how to better tailor their activities in line with a cultural lens. Originality/value The study provides empirical grounding for claims concerning the role of culture in planning interventions in Indonesia and other similar contexts.

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.

This article is part of the special cluster titled Bukovina and Bukovinians after the Second World War: (Re)shaping and (re)thinking a region after genocide and ‘ethnic unmixing’, guest edited by Gaëlle Fisher and Maren Röger. This article explores ways in which Habsburg nostalgia has become an important factor in contemporary place-making strategies in the city of Chernivtsi, Western Ukraine. Through the analysis of diasporic homecomings, city center revitalization, and nationalist rhetoric surrounding the politics of monuments, I explore hybrid and diverse ways in which Habsburg nostalgia operates in a given setting. Rather than a static and homogenous form of place attachment, in Chernivtsi different cultural practices associated with Habsburg nostalgia coexist with each other and depending on the political context as well as the social position of the “nostalgic agents” manifest themselves differently. Drawing from my long-term ethnographic fieldwork, I argue that in order to fully understand individuals’ attachment to space, it is necessary to grasp both the subtle emotional ways in which the city is experienced by individuals as well as problematize the role of the built environment in the visualization of collective memory and emotions of particular groups. The focus on changing manifestations of the Habsburg nostalgia can bring then a better understanding of the range and scope of the city’s symbolic resources that might be mobilized for various purposes.

This article expands on current conceptualizations and applications of precarity by exploring the everyday socio-spatial complexities of migrant squatters living in informal hotels in the center of Buenos Aires, Argentina. Through ethnographic methods, this research investigates squatters’ practices of negotiating access to shared domestic spaces and resources, while experiencing long-term waiting for eviction from their home and potentially from the city center. Employing a cultural geographies approach, this work is concerned with understanding the ways in which precarity is routinely experienced in the micro-spaces of everyday life. Precarity is examined in its temporal and spatial manifestations, with particular emphasis on gendered experiences and home-making practices. Moving through daily spaces and routine situations, I document how precarity is embedded in the mundane tasks of the domestic, and as a result, unevenly impacts women whose traditional roles as mothers and caretakers mean that they are often at the fore of place-making practices and responsibilities.

The phenomenological case study covers the limited research on Chinese students‟ experiences of nature in a tropical rainforest in Thailand. Macau is a very small place with only 20 % of natural resources remaining but Chinese students are born to be detached from these natural environments. Their comfortable lifestyle leads to a rise of unsustainable behavior such as an increased in consumption and household waste. With numerous researches that review the benefits of nature including an enhancement in environmental friendly behavior, a 7 d self-funded experiential learning program in a tropical rainforest in Thailand in 2015 was initiated in fostering 12 Chinese students‟ pro-environmental identity and behavior. Findings show the majority of students‟ pro-environmental identity and behavior is enhanced and they are trying to reconnect with the natural environment more often than before.

AbstractThis chapter shows how carnival has been used to counter the impact of Brazil’s colonial history on its asylums and perceptions of madness. Colonisation of Brazil by Portugal in the nineteenth century led to a process of Europeanisation that was associated with dismissal of non-European customs and values as “mad” and sequestration of the poor from the streets into asylums. Bringing together the work of the two authors, the chapter describes through a case study how a carnival project, Loucura Suburbana (Suburban Madness), in which patients in both long- and short-term asylum care play leading roles, has enabled them to “reclaim the streets,” and re-establish their right to the city as valid producers of culture on their own terms. In the process, entrenched stigmas associated with having a history of mental illness in a local community are challenged, and sense of identity and self-confidence can be rebuilt, thus contributing to long-term improvements in mental well-being. Further illustrative materials are available including photographs and video clips.

When a child has been abused by his or her father or father-figure and makes the statement ‘I want Dad to come home’, whose voice are we hearing in treatment, how do we interpret and respond to what the child is saying? Understanding and responding to the voices of victims of abuse is a complex issue. This paper explores the issues of listening to and responding to a young vicitm of abuse in the context of the impact of the abuse on this young person, and how these issues emerged and were addressed in the therapeutic process. Amanda, a 13-year-old girl, disclosed sexual abuse by her stepfather. In the initial months of counselling she repeatedly expressed her wish for her stepfather to return home. Amanda’s response to therapy, the short-term and long-term impact issues that were addressed, and the various therapeutic techniques that were used to assist in her recovery, are traced in the context of theoretical considerations.
