Large amounts of the most diverse waste are produced in urban environments, being the landfill one of the most common forms of disposal of these wastes. The need for research on the redevelopment of landfill areas lies in the dynamism and externalities of urban spaces, which generates the need to rebuild degraded areas to promote economic, social, and environmental benefits. In Brazil, there is an expectation that open and controlled dumpsites will be replaced by sanitary landfills. In this sense, the present study seeks to identify alternatives to re-urbanization for areas of deactivated landfills as a way to increase the sustainability of cities, presenting solutions already adopted in Brazil and international trends. To this end, a bibliometric analysis and an extensive bibliographic review were conducted. The main alternatives found were: open spaces (parks, sports and leisure centers), use for agriculture, woods and reforestation areas, intensive use for commercial purposes, housing and energy generation. The main contribution of this article is to open the discussion about what will be the use of these new landfills in the post-closure phase of waste disposal, having in mind an adequate planning of these new landfills, allowing them not to become environmental liabilities when they are deactivated.

In a scenario in which the climate changes subject urban centres and large cities to high levels of environmental vulnerability and criticality underway, it is evident the need to define operational and straightforward decision-making tools capable of prefiguring and verifying the effectiveness of urban transformation climate-adaptive regeneration processes. The Climate Adaptive Design Index for the Built Environment (CADI-BE) tool has been developed to assess the adaptive capacity and level of performance of open urban spaces to the stresses due to the increase in global average temperatures. The repercussions of these phenomena cause the occurrence of heatwaves and the urban heat island effect (UHI), bringing out the inability of cities to cope with changes in the climate, making urban open spaces unlivable and no longer the ideal habitat for everyday life and social interactions.

Street cries, though rarely heard in Northern European cities today, testify to ways in which audible practices shape and structure urban spaces. Paradigmatic for what Gilles Deleuze and Felix Guattari call ‘the refrain’, the ritualised and stylised practice of street cries may point at the dynamics of space-making, through which the social and territorial construction of urban space is performed. The article draws on historical material, documenting and describing street cries, particularly in Copenhagen in the years 1929 to 1935. Most notably, the composer Vang Holmboe and the architect Steen Eiler Rasmussen have investigated Danish street cries as a musical and a spatial phenomenon, respectably. Such studies – from their individual perspectives – can be said to explore the aesthetics of urban environments, since street calls are developed and heard specifically in the context of the city. Investigating the different methods employed in the two studies and presenting Deleuze and Guattari’s theory of the refrain as a framework for further studies in the field, this article seeks to outline a fertile area of study for sound studies: the investigation of everyday refrains and the environmental relations they express and perform. Today changed sensibilities and technologies have rendered street crying obsolete in Northern Europe, but new urban ritornells may have taken their place.

A great deal of researchers elaborated on the importance of the urban spaces and human life. Urban spaces are necessary types of spaces for a city and they have a timeless value. This research is focused on people’s perception about urban spaces in Larisa, Greece, a medium-sized city selected as case study. An electronic questionnaire survey was conducted and conclusions are drawn on how adequate are the urban spaces in Larisa. Moreover, people are asked to propose ideas on how other spaces, function more as urban gaps, can be integrated on the urban grid. In that way, it is easy to study what people believe about the city’s life and how the existing urban spaces function. Some conclusions derived from this research can be also useful in succeeding a combined traffic and urban planning in other Greek, in the context of the implementation of a Sustainable Urban Mobility Plan (SUMP).

PurposeUrbanization is characterized mainly by changes in land use and conversion of natural areas into built environments, as well as by a series of impacts, such as loss of biodiversity, which interfere with the proper functioning of ecological networks.Design/methodology/approachThus, the authors apply a bibliometric analysis using the term “Urban Trees” in the “Web of Science” database, between 2009 and 2019, as a keyword to include all urban green structures and identify the main aspects of urban ecological relationships. They found 8,367 published articles.FindingsThis review identified the main countries and research institutions that operate in urban afforestation. In general, developing countries seek to understand the environmental benefits that urban afforestation can provide, demonstrating the importance of maintaining existing green areas in urban centers to promote the balance of the ecosystem. It depends directly on the flow of ecosystem services provided by green infrastructures in the city, contributing significantly to carbon sequestration, retention of particulate matter, mitigation of heat islands and reduction of surface runoff, directly favoring the health and well-being of the population. The authors conclude that the actions currently implemented in urban afforestation, especially to increase the richness and abundance of species, will be decisive for the future of urban centers and the construction of more sustainable and egalitarian cities.Originality/valueThis work sought to develop a bibliographic research based on information obtained by bibliometric analysis that has the ability to identify trends and volumes of scientific production in a given area of knowledge.

This paper focuses on urban planning strategies to adapt cities to the increasing rising of temperatures during summer heat waves. The main target is to investigate which configuration and distribution pattern of green spaces could effectively improve natural cooling of urban environments. Although the benefit that green areas give to natural cooling is well known, this kind of studies has hardly been carried out, especially at an urban scale where it is crucial to define quantities and density of green areas to address open spaces design. To reach this goal, a methodology based on the interpretation of the statistical correlation among temperature, urban parameters and green areas configurational indicators was implemented and applied to the case study of the Municipality of Naples, performing all the analysis in a GIS. Results provide guidelines to improve natural cooling in urban areas adopting the most effective configuration and distribution of green areas within a densely-built context.

Over the last decade, municipal solid waste generation in Phnom Penh has increased noticeably; however, the waste management system is far from satisfactory. Considerable amount of waste is left uncollected, as well as intentionally disposed of in public open spaces. External and internal factors can trigger these problems. Possible external factors are low collection frequency, low cleaning services, and insufficient facilities such as small dumpsters. Possible internal factors, which also play an important role in this issue, include low awareness, insufficient knowledge, and low responsibility for personal waste. To examine the influences of these internal and external factors on people’s waste disposal behaviors, we selected and conducted a questionnaire survey at four sites in Phnom Penh that differ in waste collection frequency and population density. A total of 413 valid responses were obtained. We developed a structural equation model to explain people’s intentions not to dispose of waste in public open spaces. The results showed that personal and social norms, such as perception of social pressure from friends and family and from the government, had significant influences on intention, whereas the influence of external factors was much smaller.

Flooding is the most common natural hazard in Europe. Cities cannot rely only on underground solutions which are expensive and inflexible. In order to reduce the negative impacts of flood, open and surface solutions play a key role in the efficiency of urban drainage systems. Utilizing the earth's surface as part of sustainable water infrastructure, also as powerful element for creating the space, adds multiple values to our urban environments. This article suggests a framework to increase the likelihood of turning the idea of flood resilient city to a best practice. The paper is clarifying the design principles. The target is turning a space to a functional place by applying drainage techniques in urban design, which requires robust local integration between the urban space and technical solutions. The study of storm water management in the Swedish and Dutch contexts was an important base for this formulation. Considering the important share of urban design in urban transition success, the paper is focusing on categorizing the required steps of flood resilient urban design.
