A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista.

Even though tourists increasingly value sustainable practices in tourism businesses and destinations, price is still one of the main determinant factors in their decisions. Therefore, for destination managers it is essential to understand tourists’ willingness to pay an additional price to visit a place where sustainable practices are adopted. In this context, and building on social psychology theories, the present study proposes and tests a causal model encompassing tourists’ Willingness To Pay (WTP) for sustainability in tourist destinations as well as their own sustainability attitudes, namely: Environmental Beliefs, Ecotour Attitudes, and Sustainable Consumption Behaviour. To this end, data were collected through a questionnaire survey of Portuguese tourists (n = 567). The hypothesised relationships between the latent variables were then tested using Structural Equations Modelling (SEM) procedures. The results show that Environmental Beliefs significantly affected both Ecotour Attitudes and Sustainable Consumption Behaviour, and that the latter two significantly affected WTP. However, no significant effect of Environmental Beliefs on WTP was found. These findings provide useful insights for destination managers aiming to more effectively cater to sustainability-oriented tourists. Future research should attempt to assess the role of other determinants of WTP.
