## 3 Methods and Data
### The Use of Participatory-Based Methodologies
#### 3.2.2 Delphi's Approach to Addressing Climate Change Challenges
The second questionnaire aimed to identify the predictability and priority of the initial measures and those added by the participants. The time horizon was created based on the United Nations proposal included in the 2030 Agenda--Sustainable Development Goals (SDGs) and the latest report by the European Travel Commission (2018) [67], as a response to the challenges posed by the 2015 Paris Agreement. 2.3 The Workshop as the Final Stage of Research--The Launch of an Intervention Agenda for Urban Tourism  
The latest method of research analysis, a workshop entitled '1 st Workshop on Strategies for adapting urban tourism to climate change', was held in a framework of (post-) pandemic opportunities. This workshop aimed to outline an intervention agenda for PMA and the municipality of Porto and to contribute to the advancement of the scientific subarea of tourism climatology. It sought to integrate other territorial stakeholders, namely, tourism agents (travel agencies, companies in the sector, politicians, and technicians from local and regional institutions) instead of just considering the opinion of academics. Eighty-five participants attended the workshop, synchronously and in-person, on 20 October 2021. The workshop was held in three sessions, of which:  
1. Two were online sessions about the impacts of climate change on urban tourism in the Mediterranean and the need of public policies, as well as a communication agenda to address the problem;
2. One was an in-person session, with all relevant issues being discussed in a 'World Cafe' (Appendix D). Initial activities and presentations have contributed to a greater awareness of climate change at regional and local level. The second moment allowed the participants to identify and consider potential impacts and to reflect on the importance of their role as professionals directly or indirectly related to the area. \begin{table}

Table 3: Sociodemographic profile of expert panel. This workshop was aimed at master's and PhD students in several social and environmental disciplinary areas (e.g., Geography, Tourism, Urban Planning, Architecture and Urbanism, Sciences Communication and Sociology), senior technicians of municipal councils working in the fields of urban planning, environment and public space, and other professionals who exercise functions in thematically related areas of intervention (e.g., regional, and urban development). The following were among the workshop's main objectives:  
1. Identify good practices developed at international level;
2.
