ABSTRACT
From an economic point of view, the tourism sector is one of the most important in the world with religious tourism, such as pilgrimages, being a growth area. Tourism activities also make a significant contribution to CO2 emissions (roughly 8% of the world's carbon emissions). In this framework, the main objective of this research is to develop an integrated sustainable model by assessing the impact of pilgrimages to the Camino Lebaniego (Lebaniego Way) in the Cantabrian region, which is one of the most popular routes in northern Spain. To do this, it is necessary to quantify the environmental impacts of this activity since this is a key element in establishing appropriate and effective environmental management programmes. This study uses the Life Cycle Assessment (LCA) method, focused on the Carbon Footprint (CF) impact category, to assess the greenhouse gas (GHG) emissions of this activity considering 'a pilgrim who completes the route in three days' as the selected functional unit (FU). In addition, the sub-sectors of accommodation, food and beverages, and waste management are taken into account. Following this route generated a total of 13.69 kg CO2 eq./FU, of which accommodation and the services offered there contributed almost 71.47%, food was 17.08%, and waste management 11.45%. The evening meal and propane consumption were the hotspots in the hostel, accounting for almost 74% of the total impact, so alternatives were proposed to reduce the impacts associated with these. In terms of transport, it was found that for the same destination, it was better to use a car rather than a plane, because the associated CO2 emissions were lower. Finally, these aspects are discussed and improvement measures for reducing GHG emissions are proposed, involving the introduction of good practices and environmental commitments from the pilgrims themselves, as well as enterprises and local communities. Ecolabels and environmental certifications should become a key tool for sending this signal to the market as should the use of public transport to the destination, among other actions. Ultimately, religious and nature tourism seems to be on the upturn, and it is likely that pilgrimage routes could be the next post-COVID travel trend.
ABSTRACT
Department of Business and Administration, University of Cantabria, Spain Sustainable tourism should be promoted as a new system for the sustainable management of resources from a socioeconomic and environmental point of view. For this purpose, it is necessary to develop a tool capable of assessing the impacts associated with each of the stages of the sector and to identify which actions are currently being addressed in the tourism sector in order to achieve the desired sustainability in the sector. This timely study aims to describe the current framework of life cycle assessment (LCA) and its application to the tourism sector. To address these questions, the geographical distribution, the temporal evolution of the publications, as well as the most relevant characteristics of the tourism industry articles were evaluated such as the functional unit and system boundaries considered. The study identifies key recommendations on the progression of LCA for this increasingly important sustaining tourism sector. As important results, it stands out that 94% of articles focused on LCA methodology were from the last decade and almost 26% of the articles reviewed cover sustainable tourism term, considering environmental, social and economic aspects. Specifically, LCA is a highly effective tool capable of assessing direct and indirect carbon emissions at all stages of the activity as well as the socioeconomic and environmental impacts generated in the tourism sector. This review showed that the most common environmental indicator in the LCA methodology is the carbon footprint. COVID-19 pandemic is also an object of discussion in the framework of the sustainable tourism together with advocating support for the eco-labelling and digitalisation of the tourism experiences as valuable tools to minimize environmental negativities, to promote mechanisms to access green markets and to frame successful synergies. © 2022 WIT Press.
ABSTRACT
Improving the food supply chain efficiency has been identified as an essential means to enhance food security, while reducing pressure on natural resources. Adequate food loss and waste (FLW) management has been proposed as an approach to meet these objectives. The main hypothesis of this study is to consider that the "strong fluctuations and short-term changes" on eating habits may have major consequences on potential FLW generation and management, as well as on GHG emissions, all taking into account the nutritional and the economic cost. Due to the exceptional lockdown measures imposed by the Spanish government, as a consequence of the emerging coronavirus disease, COVID-19, food production and consumption systems have undergone significant changes, which must be properly studied in order to propose strategies from the lessons learned. Taking Spain as a case study, the methodological approach included a deep analysis of the inputs and outputs of the Spanish food basket, the supply chain by means of a Material Flow Analysis, as well as an economic and comprehensive nutritional assessment, all under a life cycle thinking approach. The results reveal that during the first weeks of the COVID-19 lockdown, there was no significant adjustment in overall FLW generation, but a partial reallocation from extra-domestic consumption to households occurred (12% increase in household FLW). Moreover, the economic impact (+11%), GHG emissions (+10%), and the nutritional content (-8%) complete the multivariable impact profile that the COVID-19 outbreak had on FLW generation and management. Accordingly, this study once again highlights that measures aimed at reducing FLW, particularly in the household sector, are critical to make better use of food surpluses and FLW prevention and control, allowing us to confront future unforeseen scenarios.
