## 5 Discussion and Conclusions
### Limitations and Future Research Directions  
The present research faced a few limitations, namely, the impossibility of gathering many people in the same space at the same time due to COVID-19, a fact which came to significantly affect these processes of collaboration and citizen science. Another gap is related to the impossibility of hearing all the stakeholders, depending on the type of method to be applied. In another study developed by the team, tourists were asked about their perception of the destination [5, 27]. Nonetheless, we believe that in the medium and long term, it will be necessary to go a step further and include them in this exercise of planning tourism resources in the face of the challenges of climate change. However, the inclusion of stakeholders and experts in planning proposals contributes to an integrated assessment based on general market trends, demographic changes, travel behavior and the relationship with climatic conditions. Several studies have highlighted the need for further research on an international scale and with a more detailed analysis at local level. Therefore, we must emphasize the importance of developing guidelines for a more resilient adaptation to climate change and, in the context of this research, several considerations should be made for future investigations, including the following:  
1. A holistic assessment is essential to address other sectors directly or indirectly related (e.g., transport, agriculture, and energy); in addition, more information on the impacts of climate change on urban tourism is needed during the various seasons;
2. There are still not enough innovative services capable of translating and adapting complex climate information from decision-makers to decision-making related to urban tourism; market and feasibility studies of the measures, with guidance on how to interpret the results and how to prepare and adapt to climate change can benefit the destination;
3. We should work the several data from this research to account for the effects of some of the measures, solutions and resources identified;
4. New workshops should be held, bringing together the academic community, politicians and decision-makers, municipal council technicians, tourism company workers and members of the civil community; previous insights into the review and application of methodologies have already been validated and other requirements and needs of end-users (tourists) have been discussed, but this approach deserves continuous adaptation;
5. Creation of a web platform where the data resulting from this research project is disseminated and fed with other additional initiatives.
