Tourism and Air Quality during COVID-19 Pandemic: Lessons for the Future

The pandemic caused by coronavirus SARS-CoV-2 (associated to the disease named COVID-19) is having a global impact that affects health, the economy and the environment. These impacts are negative in most of the sectors but benefits also occurred in specific fields. Tourism was one of the most negatively affected economic sectors, and in terms of benefits, the improvement of air quality can be highlighted, with positive health implications. This paper aims to evaluate the impacts on these two particular fields-tourism and air quality-focusing on Portugal due to the relevance of tourism in the country. The research carried out in this paper enables us to find the most critical areas and identifies lessons learnt and recommendations for the post-COVID period. Tourism and air quality data were collected for both 2019 and 2020 and compared in terms of quantitative and spatial analysis. The Lisbon metropolitan area-the geographical area where the capital of the country is located-was the area that suffered the most negative impacts in terms of tourism activity but was also the one where highest benefits in terms of air pollution reduction and human exposure were felt. Recommendations for future strategies are suggested, including new concepts of tourism connected to the environment; the investment in online/virtual tourism activities; promotion of the domestic market; mitigation of the over-tourism problem and using environmental issues, such as air quality, as new attractiveness criteria for tourism destinations.
