Introduction: During the COVID-19 lockdown significant improvements in urban air quality were detected due to the absence of motorized vehicles. It is crucial to perpetuate such improvements to maintain and improve public health simultaneously. Therefore, this exploratory study approached bicycle infrastructure in the case of Munich (Germany) to find out which specific bicycle lanes meet the demands of its users, how such infrastructure looks like, and which characteristics are potentially important. Methods: To identify patterns of bicycle infrastructure in Munich exploratory data is collected over the timespan of three consecutive weeks in August by a bicycle rider at different times of the day. We measure position, time, velocity, pulse, level of sound, temperature and humidity. In the next step, we qualitatively identified different segments and applied a cluster analysis to quantitatively describe those segments regarding the measured factors. The data allows us to identify which bicycle lanes have a particular set of measurements, indicating a favorable construction for bike riders. Results: In the exploratory dataset, five relevant segment clusters are identified: viscous, slow, inconsistent, accelerating, and best-performance. The segments that are identified as best-performance enable bicycle riders to travel efficiently and safely at amenable distances in urban areas. They are characterized by their width, little to no interaction with motorized traffic as well as pedestrians, and effective traffic light control. Discussion: We propose two levels of discussion: (1) revolves around what kind of bicycles lanes from the case study can help to increase bicycle usage in urban areas, while simultaneously improving public health and mitigating climate change challenges and (2) discussing the possibilities, limitations and necessary improvements of this kind of exploratory methodology.

The research aims to prioritize the solutions to overcome the challenges of Lean Six Sigma 4.0 (LSS 4.0). It is an integrated approach with lean, six sigma, and Industry 4.0 attributes. This integrated approach helps to achieve organizational excellence and sustainable development goals. Fuzzy stepwise weight assessment ratio analysis (fuzzy-SWARA) was used to estimate the weights of LSS 4.0 challenges. Furthermore, fuzzy-weighted aggregated sum product assessment (fuzzy-WASPAS) was used to prioritize the LSS 4.0 solutions. In this study, 23 challenges and 23 solutions of LSS 4.0 implementation were identified with the help of an extensive literature review and discussion with the area experts having vast experience. Management participation in LSS 4.0 implementation and planning for long-term vision were found to be the topmost solutions to overcome LSS 4.0 challenges. To the best of our knowledge, to date, the prioritization of solutions to overcome the challenges of LSS 4.0 have not yet been investigated in the developing economic context.

Salt mines, a significant category of local, regional, national, and/or European underground heritage, are becoming attractive tourism destinations. This paper examines three cases of salt mining in different European countries, namely Wieliczka in Poland, Campina de Cima in Portugal, and Turda in Romania. They are analyzed in the context of history, typical attributes of their attractiveness, and new uses after the salt extraction was or is going to be stopped, in order to detect their unique values as important assets for both Underground Built Heritage (UBH) and Salt Heritage Tourism (SHT). The results of their comparison show that despite a positive impact related to their protection as cultural and industrial heritage, there are also some negative aspects related to increasing costs of their maintenance and adaptation of salt mines to new functions and to meet the tourism needs. By putting in place measures to enhance the awareness of their values and for activating the local community, the three mines are showcases for the economic outputs for their sites and regions, as well as for increasing knowledge regarding UBH.

Many studies have been carried out to evaluate the sustainability of transportation systems, but little attention has been given for the design of roadway intersections. This study aimed to establish a framework and develop a tool to assess the sustainability of roadway intersections from a road-user perspective. Sustainability indicators at the strategic level were extracted from the literature and were utilized with relative weights to develop economic, environmental, and social indices that would be combined into a composite sustainability index (CSI) tool. The tool was applied to four case studies of intersections in Al Ain, United Arab Emirates. For each case study, the sustainability of fifteen design alternatives was evaluated for different scenarios of traffic volume and operational speed. Dimensional indices and the overall CSI were determined using the Multi-Criteria Decision Making method. Results indicated that traffic volume had a significant impact on intersection sustainability ranking, while the effect of operational speed was insignificant. Moreover, weight assignment had an effect on determining the most sustainable design alternative, where the best alternatives of the dimension with the major weight would most likely be the most sustainable. The developed tool would assist decision-makers in other cities to assess intersection projects that correspond to their regional goals.

The global food industry has a critical role to play in achieving multiple Sustainable Development Goals (SDGs). Accordingly, global firms in this industry pursue a wide array of sustainability issues. However, it remains unclear as to how leading firms differ from laggard firms in the industry in terms of their overall approach to sustainability and SDGs. To bridge this gap, we conducted in-depth interviews with sixteen experts comprising representatives of global firms, non-government organizations (NGOs), and researchers and academics. First, we identified five sustainability performance criteria—engagement with multi-stakeholder groups (MSGs), measurement of sustainability outcomes, resource commitment by top management, integration of sustainability programs with traditional management systems, and a robust process for the identification of specific sustainability issues or SDGs. Then, we found that leaders and laggards are markedly different in their approaches to pursue these performance criteria.

Purpose The purpose of this paper is to investigate the impact of information and communication technology (ICT) development and terrestrial and marine protection on the economic and environmental sustainability of small-island tourism countries. The current study expands the smart specialisation literature in the context of small-island tourism nations. It also proposes sustainable future growth strategies for these countries. Design/methodology/approach This paper adopted structural equation modelling using the data of 14 island nations between 1995 and 2014. The selection of countries was based on a set of criteria borrowed from literature. Findings The results indicate that the development of ICT infrastructure was not only associated with a higher inflow of tourists and a higher GDP per capita but also with a higher carbon dioxide (CO2) emission. Results also suggest that higher protection of terrestrial and marine areas has no impact on tourist inflows in tourism countries. Also, higher protection decreases the dependence of the total output on the tourism sector. Research limitations/implications A limitation of this study is the lack of available macro data on some other relevant variables for the countries studied. Social implications Following the findings of this study, the governments of these countries should make stringent environmental regulations and relax the telecom regulations for sustainable smart specialisation. Originality/value This study presents a novel insight into the sustainability challenge of island nations through the lens of smart specialisation. It also contributes to the literature on ICT and development.

PurposeThe pressure of globalization has raised social concerns related to the protection of the environment, forced companies to use sustainability as a strategic weapon to fulfill the legal obligations and achieve overall competitiveness. It is reported that small- and medium-sized enterprises (SMEs) are globally responsible for approximately 70 percent of the industrial pollution, justifying urgent attention to the operations of these businesses. The purpose of this paper is to analyze the impact of sustainability orientation (SO) and supply chain (SC) integration implemented by SMEs on their sustainable procurement (SP) and design. Moreover, this study examines how SMEs’ SP and design affect their environmental and cost performance (CP).Design/methodology/approachThe authors develop a comprehensive model to test the relationships among SC, SC integration, SP, sustainable design (SD), environmental performance (EP) and CP at the SMEs level. The authors investigate the relationships of the mentoned factors by a data set that is collected from 358 Indian manufacturing SMEs.FindingsThe results indicate that in the SMEs’ context: SO positively influences both SP and SD; external integration positively affects SP; internal integration positively affects SD; SP positively influences EP and has not impact on CP; and SD positively influences both EP and CP.Originality/valueThis study provides a broad view of the relation between driving factors that may direct SMEs toward a better sustainability performance and offers practical managerial insights into these important business entities.

The objective of this paper is to present alternative land development scenarios for the sustainability impact assessment of transport-land-use relationship in the Leipzig-Halle Region. Using the MOLAND Model that was applied to a declining urban region for the first time, two different land-use scenarios were developed representing a baseline <em>dispersed</em> development and an alternative <em>compact</em> development case. The assessment of land-use-transport relationships is carried out incorporating the use of social, economic and environmental indicators. The impacts and indicators were specified and evaluated subject to a quantitative and qualitative assessment. The findings imply that a compact development scenario is preferable over dispersed development scenario in terms of potential quantitative data on the benefits to the environment and society. In contrast, dispersed development in the baseline case indicates the costs of such development exceed the benefits. The results of this type of scenario analysis provide an objective evidence basis in policy evaluation and decisions regarding future urban developments. This research was developed from several scenarios created with the key stakeholders of the Leipzig-Halle Region from research originally conducted as part of the PLUREL Project in 2012 and updated in 2016. It aims at contributing to literature by providing a sustainability assessment framework for rapid rail infrastructure provision that incorporates socio-economic and environmental impact assessment of alternative future urban form scenarios into the analysis. In addition, due to MOLAND features, it provides the opportunity for the sustainability impact assessment of different forms of urban development linked with transport infrastructure provision in the Region and compare the findings with other case study areas in Europe and internationally.
