Transport is the main enabler of tourism, but also one of its main sources of environmental impact. This paradoxical condition is even more controversial if considering the reluctancy of policymakers to introduce traffic management strategies, as they fear possible drops in tourism demand. This chapter addresses the ‘tourism-traffic paradox’ as a wicked problem and explores adequate and efficient policy interventions to foster sustainable mobility in Alpine destinations, minimising rebound effects in tourism demand. The chapter is focussed on the exemplary case of the Dolomites World Heritage Site (WHS), as this Italian area has experienced a long-lasting process of evidence-informed decision-making in transport, with two pilot actions for traffic calming in 2017 and 2018. The main goal of those actions was to shift the modal choices of tourists, to optimise the traffic network use and to minimise environmental impacts. The policy interventions were rooted in a sustainability governance approach, that is, they were creating a government-led network of stakeholders, including several academic experts, involved in the transport planning and monitoring phase. Advantages and disadvantages of this government-led network to solve the tourism-traffic paradox are discussed in the chapter.

The study aims to critically evaluate the Kochi Water Metro as a model for sustainable urban transportation and extract valuable lessons for policymakers and cities seeking similar initiatives. The study employs a qualitative data-driven approach, utilising a longitudinal case study design, open-ended interview questions, direct observations and qualitative content analysis. The Kochi Water Metro has emerged as a transformative urban mobility initiative, enhancing connectivity while simultaneously reducing congestion on roads. The project's sustainable practices have minimised its carbon footprint, contributing to environmental sustainability. Economic benefits have accrued through increased tourism, employment opportunities and improved local livelihoods. The project's adaptability to local conditions and changing needs further underscores its sustainability. Limited data from the project's early years necessitate further longitudinal analysis. The focus on benefits may overlook potential challenges, warranting broader investigation. Reliance on qualitative data may restrict generalisability. The Kochi Water Metro serves as a beacon for sustainable and equitable transportation solutions. It serves as a blueprint for policymakers, providing practical lessons in project implementation, especially its integration with existing modes enhances overall urban mobility. Policymakers should consider replicating elements such as electric boats and integrated networks, while emphasising environmental sustainability, accessibility and community engagement. The comprehensive evaluation provides valuable insights into the project's tangible impacts and replicable elements. The innovative approach blends sustainable practices, operational resilience and community engagement, serving as a model for cities seeking sustainable, equitable and efficient transportation solutions.

As the tourism industry recovers from the devastating effects of the global pandemic, meeting the targets of the Sustainable Development Goals (SDGs) remains to be a global “deadline” where tourism is seen as a major contributor. While disruptions to business-as-usual practices such as COVID-19 present unprecedented challenges, they can also provide opportunities for strategic innovation to change behavior toward sustainable tourism experiences. Active transport for low-carbon tourism such as walking or cycling tours have risen in popularity in recent years, and especially postpandemic, as they provide opportunities for a more personalized experience while health and safety protocols can still be implemented. They also present health benefits for the individuals while contributing to environmental sustainability and climate mitigation strategies of the tourism industry. This book chapter presents cases of various forms of tourism activities that use active transport, focusing on walking tours and cycling tours. Various companies offering tours under these modes are discussed and presented. These two modes promote authentic cultural and heritage tourism experiences through the local experts that provide the services.

This study extends the current understanding of halal tourism at an island destination. Specifically, this study aims to explore the attributes of halal tourism in the local islands of the Maldives, a fully Muslim country where tourism is the primary source of income for residents. To accomplish this, Muslim travellers’ experiences were examined using the process theory of travel, the halal tourism concept and the service marketing perspective.

The study used a qualitative research methodology and conducted interviews with Muslim travellers visiting the local islands of the Maldives.

The findings affirmed the five established generic attributes of halal tourism and generated another three emergent attributes of halal tourism, specific to an island destination. The study further enhances the existing knowledge of the generic attributes of halal food and beverage, prayers and mutual respect and benefits. It also establishes that the dimensions of safety and privacy, value for money, perishability and heterogeneity characterise all the emerging halal tourism attributes. The study concludes that halal tourism is an experience imbued with values that promotes dignified tourism.

The findings on the specific attributes of halal tourism at an island destination extend overall understanding of the halal tourism concept and process. The fact that the Maldives is entirely Muslim offers a unique opportunity to explore the normative attributes of halal tourism in an island destination. This enhanced understanding contributes to effective managerial practices aimed at developing competitive halal tourism services.

The present study aims to inform the requirements for developing a sustainable rating tool for small-scale infrastructure projects (SSIPs) through research findings.

A review-based comparative study of existing infrastructure sustainability (IS) rating tools for assessment of SSIPs is presented. Key stakeholder participants of the existing IS rating tools, are interviewed to identify existing barriers and requirements for sustainability rating. The study further presents possible rating tool options to optimise the sustainable performance evaluation of SSIPs.

Findings of this study indicated that prevalent IS rating tools are majorly applied to large-scale infrastructure projects and sustainability of SSIPs are seldom assessed. Based on a literature review and series of interviews, it was found that user friendliness, efficient structure, training and technical support, cost effectiveness and stakeholder recognition are the five key requirements of a sustainability rating tool for SSIPs. Additionally, six sustainability assessment options were proposed for SSIPs which range from pathways for existing tools through to new, customisable tools. Upon comparison, a new modified tool with verification process and revised tool with defined grouping of sustainable criteria was more effective for evaluation of SSIPs.

Use of case specific information for validation and framework development may lack generalisation. However, methodology can be used for future decision-making by making necessary adjustments to suit different local regional requirements.

Despite lack of generalisation, the findings can lead to future general studies on sustainability of SSIPs. Findings of the study provide foundation knowledge and awareness for sustainability evaluation of SSIPs.

This paper reviews and analyses renewable energy options, namely underground thermal, solar, wind and marine wave energy, in seaport cargo terminal operations.

Four renewable energy options that are deployed or tested in different ports around the world are qualitatively examined for their overall implementation potential and characteristics, and their cost and benefits. An application to the port of Singapore is discussed.

Geophysical conditions are key criteria in assessing renewable energy options. In the case of Singapore, solar power is the only suitable renewable energy option.

Being a capital-intensive establishment with high intensities of cargo operations, seaports usually involve a high level of energy consumption. The study of renewable energy options contributes to seaport sustainability.

A key recommendation is to implement a smart energy management system that enables the mixed use of renewable energy to match energy demand and supply optimally and achieve higher energy efficiency.

The use of renewable energy as an eco-friendlier energy source is underway in various ports. However, there is almost no literature that analyses and compares various renewable energy options potentially suitable for cargo terminal operations in ports. This paper narrows the knowledge gaps.

This chapter focuses on cycle tourism using Bambike (Bamboo Bike) as sustainable transportation in the heritage site of Intramuros to promote cultural awareness and environmental preservation. Bambike is a bicycle where parts are made from natural bamboo and abaca with aircraft grade alloys tested for durability that passed the standards in the industry. The purpose of this chapter is to determine the value of cycle tourism using Bambike to promote green tourism in Intramuros and preserve its attractions. Its significance and benefits as to economic, environmental, and sociocultural impacts have been analyzed. The information source and data collection for this research was from the selected local and international tourists in Intramuros who have experienced and booked a trip with Bambike. An interview with structure questionnaire was done for the tourists and Bambike staff. It was concluded that Bambike can contribute to create site awareness leading to desire to preserve the heritage sites of Intramuros.

The nexus of transport and tourism is critical to the 2021 Glasgow Declaration which sets out the net zero by 2050 goal for global tourism in the context of the Paris Agreement. Numerous small and medium-sized urban destinations (SMUDs) populated under one million are constrained by a limited capacity to manage visitor flows and increasing greenhouse gas (GHG) emissions. This paper aims to develop an analytical approach for urban practitioners, based on a case study in Taiwan, to identify the low-emission pathway and strategies for tourism passenger transport.

A GHG emissions assessment and scenario analysis were enabled by historical activity data from official sources and projected scenario data from the International Energy Agency. The scenarios were established based on the avoid-shift-improve framework for low-carbon transport.

To drive tourism passenger transport to a low-emission pathway compatible with the Paris Agreement goal, three low-carbon transport strategies, i.e. “Avoid,” “Shift” and “Improve,” shall be applied all together, with a focus on “improving” the efficiency of heavy-duty vehicles and rail transport. Meanwhile, alternative tourism and integrated transport policy packages could enhance demand-side management of visitors’ mobility, enabling the “avoid” and “shift” strategies.

Unlike most studies that have focused on large cities or small tourist areas, this paper addressed our knowledge gap regarding the low-emission pathway for tourism transport in numerous SMUDs compatible with a 1.5°C world. The proposed analytical approach can help policymakers assess effective strategies toward the targeted pathway.

In this chapter, we propose a strategic framework for capacity-building in cross-border transport megaprojects. First, we make the case for infrastructure megaprojects as wicked policy fields marked by a complex web of stakeholders' interests and characterized by uncertainty and entrenched value divergence and conflict. Second, inspired by Pettigrew's contextualism and by drawing evidence from the case of the Lyon-Turin high-speed railway megaproject, we suggest that strategic management involves the analysis of three different albeit interconnected dimensions: the content of change, the process of change, and the context of change. Our study shows that variations in performance (content) are determined by and determine variations in (1) the openness or closure of national institutional contexts to civil society stakeholders (inner context), (2) the intensity of supervision and control functions realized by actor seating in the supranational institutional context (outer context), and (3) national and supranational actors' capability of making agreements over contested megaprojects aspects (process). We suggest that, from a strategic point of view, there is not a linear relationship between the content, context, and process of change in megaproject development. This is rather a complex nonlinear relationship that varies over time with little predictability. Time is a key factor in understanding these interactions between the content, context, and process. We claim that the capacity for organizing wickedness in megaprojects should rest on a socioeconomic logic and, in particular, on three core governance features: (1) open decision-making systems, (2) bottom-up performance management, and (3) active dialogue between proponents and opponents.

This paper aims to investigate the influence of air and rail transportation on pollution in Turkey from 1970 to 2020.

Fourier Autoregressive Distributive Lags (ADL) and Fourier Fractional ADL cointegration tests (Banerjee et al., 2017; Ilkay et al., 2021) are employed to analyze the relationship be-tween the variables. Cointegration tests that take into account soft transitions under structural changes are implemented. Structural change issues are crucial for this topic since the changes in countries’ environmental policies and transportation habits are shaped by the decisions taken in relation to environmental regulations. Finally, for robustness purposes, we tested the estimated equation with a completely different methodology. Thus, a Machine Learning (ML) analysis is conducted, through a Ridge Regression (RR).

The findings obtained by applying Fourier Autoregressive Distributive Lags (FADL) and Fourier Fractional ADL cointegration tests, which can control for structural changes, reveal the existence of a long-term relationship between the variables. In addition, FMOLS estimates emphasize that economic growth and air transport can lead to increased pollution in the long run, while rail transport reduces it. Moreover, the statistically significant trigonometric terms indicate the existence of a smooth structural change among the variables. Robustness checks are performed through a Machine Learning (ML) analysis, which roughly confirms the previous results.

To our knowledge, existing research in Turkey focuses mainly on road transport, while the impact of rail and air transport on pollution has not yet been investigated. As such, this study will be a significant addition to the academic literature.
