Tourism Planning: Policies, Processes and Relationships

There is weak conceptualization of the differentiation between migration and tourism, which has contributed to relative neglect of the relationships between these. This paper examines some of the major influences on these relationships, dividing them into two general but inter-linked categories: broad economic and social trajectories, and tourism factors. A number of specific forms of tourism-related migration are then examined in the context of these social and economic trajectories. The paper explores labour migration, return migration, entrepreneurial migration, retirement migration, and the special feature of second homes. It concludes by emphasizing the need to place studies of the links between tourism and migration more firmly into wider social science debates, and by setting out some fruitful lines of future research.

Tourism and migration : new relationships between production and consumption

Disease outbreaks and pandemics have long played a role in societal and economic change. However, the nature of such change is selective, meaning that it is sometimes minimal and, at other times, and change or transformation may be unexpected, potentially even reinforcing contemporary paradigms. A comprehensive overview of pandemics and their effects is provided. This is used to help contextualise the COVID-19 pandemic, its impact on tourism and government, industry and consumer response. Drawing on the available literature, factors that will affect tourism and destination recovery are then identified. Some measures will continue or even expand present growth orientations in tourism while others may contribute to sustainability. It is concluded that that the selective nature of the effects of COVID-19 and the measures to contain it may lead to reorientation of tourism in some cases, but in others will contribute to policies reflecting the selfish nationalism of some countries. However, the response to planetary limits and sustainable tourism requires a global approach. Despite clear evidence of this necessity, the possibility for a comprehensive transformation of the tourism system remains extremely limited without a fundamental transformation of the entire planet.
