Transport Transition

Heavy-duty trucks (HDTs) in road freight are a primary contributor of PM2.5 and NOX emissions in many cities. Shenzhen, a megacity of China, has already made great efforts to promote the green transport transition, including via the Liquefied Natural Gas (LNG) HDTs program, which may be the largest alternative fuel vehicle promotion program in the world. In order to fully understand the actual efficiency of such program, the economic and environmental impacts of LNG HDTs were analyzed in this study. The results revealed that, while the capital cost of LNG HDTs is higher than that of diesel HDTs, the aggregated cost during the entire operation period of LNG HDTs is 10% to 17% lower than that of diesel HDTs. By replacing existing diesel HDTs mode (including China-I to China-V) with LNG HDTs (100%), environmental impact analysis showed that PM2.5 and NOX emissions could be reduced by 96.7% and 73.2% in the city level, respectively. Moreover, the environmental benefits of using purely LNG HDTs versus just China-V diesel HDTs were also compared, which indicated that LNG substitution is superior to China-V, with a reduction of 20.9% for PM2.5 and 35.4% for NOX, respectively. Overall, the effectiveness of the promotion of LNG HDTs is notable in Shenzhen, and these findings could provide references for other cities to promote LNG HDTs and beyond.

Municipal waste management is an important component of ecosystem and one of the essential part in sustainable development. This paper analyzes Tripoli landfill’s situation. According to Municipality of Tripoli, the average production of waste reached 148.5 million in 2015 where all of these waste was dumped in north of the city which leads to many environmental and health crises. The maximum height point in the landfill reached 30 m in 2013 which is more than acceptable engineered height. The paper took Tripoli landfill as case study to account for the amount of economic and environmental benefits if it is subjected to around zero waste management. The study takes into account the waste generated in 2015 till 2065 by assuming 1.5 % growth in population. As a result lots of economical, healthful and environmental benefits can be extracted if the generated waste is subjected to composting, recycling, reuse and incineration instead of throwing them.

Biophilic design stems from the term biophilia; a concept that describes humans’ innate connection and love for nature. It is an innovative way to bring nature into cities, reconnecting urban residents to the natural world through the built environment, while simultaneously contributing many mental, physical and environmental benefits. Despite extensive research on the significance of biophilic design, application in many urban environments, including Toronto, is minimal. This paper investigates what, if any, obstacles may be preventing Toronto from integrating biophilic design. Research was conducted through a literature review, case study analysis and four key informant surveys. It finds that there are obstacles to local implementation including a lack of supportive planning framework, a lack of economic support and incentives, lacking professional expertise and absent demand. The paper acknowledges the literature, case studies and informant responses through the provision of recommendations that are designed to help the city overcome these obstacles.

Shed Light

Urban densification has become a desirable development strategy in several cities. In addition to its environmental benefits, densification is also advocated as able to promote conditions for better coexistence and social mix. Studies have shed light on the likelihood of densification affecting residential patterns, but no attention has been paid so far to understanding the possible consequences on school segregation dynamics. As residential and school population composition are strongly intertwined, we argue that densification patterns may be associated with specific dynamics in school segregation. This study may thus pave the way to a better understanding of an understudied relationship. Using Oslo as a case study, we investigate how urban densification, here implemented through a neoliberal planning approach, can be associated with different forms of gentrification and new social divisions that are somewhat mirrored in the school segregation patterns of the city.

Air transport plays a key role especially in countries where tourism has a great impact on the economy. In Spain, the contribution made by this industry to GPD stands at EUR 119 billion, representing 11% of GDP. This case study focuses on the Málaga-Costa del Sol Airport due to the growth the city has experienced in recent years. The research examines the impacts of this infrastructure from the perceptions of residents and tourists. We conducted 638 questionnaires and 50 interviews with residents, and 165 questionnaires and 106 interviews with international tourists from August 2019 to January 2020. A qualitative thematic analysis was carried out using the NVivo Pro software. The findings indicate that residents value the ease of travel and employment generated by the airport. However, they are concerned about the environment impacts and mass tourism. For tourists, almost no negative impacts are recorded. Residents and tourists consider the existence of positive effects on other nearby cities of Andalusia. Conclusions have practical and theoretical implications for impact researches.

For development strategic planning in urban areas, it is important to take into account, that the area is not homogenous in terms of economic, social or environmental. Ensuring fair authority’s approach is crucial for sustainable development of the area. An environmental quality index for city districts of Brno is proposed in this study. The aim of this study is to create an index, which uses public data and enables identification of city districts, which show higher vulnerability to environmental injustice. Employing GIS, data, which represent both environmental benefits, such as green and blue infrastructure, as well as environmental burden, e. g. air pollutants and noise level, was processed. Then the composite indicator was constructed. The case study showed that two basic areas can be distinguished within the city of Brno. In the northern part, urban areas with higher index values are clustered, which shows that the environmental benefits outweigh the burden. On the other hand, in the south there are city districts with a lower index value. This means that the environmental burden here is high and is not balanced by environmental benefits, which is a cause of an overall deterioration of amenities of the local population. Thus, a higher risk of environmental injustice can be identified here.

Mobility is one of the most important and challenging aspects that influence climate change, air quality, and especially the quality of citizens’ lives. Therefore, creating sustainable transport solutions makes way for different modes of transport such as the bicycle, which is continuously gaining more supporters, due to the health, economic, and environmental benefits that it provides. However, cyclists are facing several barriers (e.g., lack of infrastructure), a fact that keeps away commuters from using a bicycle for their daily trips. Investigating the factors that reflect on the commuters’ intention to use a bicycle is a sine qua non for the promotion of sustainable mobility. Therefore, the objective of this paper is the investigation of the factors that prevent residents with low experience or with no cultural/lifestyle background in regards to cycling from cycling. The case study of the city of Larnaca (Cyprus) is deployed by exploring the socio-demographic and trip characteristics of the city’s residents and their relation with the intention to cycle. A two-step approach is developed, namely Explanatory Factor Analysis (EFA) and Structural Equation Modeling (SEM). Despite the promotion of cycling that education is attempting to do (successfully), other factors (such as age, distance, and time) appear to prevent Larnaca’s residents from cycling. Among the actions that local authorities should undertake is that of safety prevention of the vulnerable users of the road network. This group includes elderly people, who need major encouraging interventions by local policymakers and stakeholders.
