Interactions between climate change and the tourism sector: Multiple-criteria decision analysis to assess mitigation and adaptation options in tourism areas

Tourism is one of the most climate-sensitive economic sectors, but also a contributor to climate change. With the effects of climate change becoming an increasing concern, the tourism sector must urgently and realistically respond by mitigating its emissions and adapting tourism businesses and destinations to the changing climate conditions. This work presents a generic methodological framework to plan, manage and implement climate change mitigation and adaptation measures in the tourism context. The methodological scheme is based on Multi-Criteria Decision Analysis for prioritizing available options applicable to a defined tourism area. The proposed framework is implemented for Greece, one of the world's most popular tourism destinations, and optimally ranks 18 mitigation and 16 adaptation measures under 4 criteria i.e. environmental benefit, applicability, cost and social acceptance. The analysis indicates that rational energy use, improvement of energy efficiency and water management/saving measures should be primarily put forward for the Greek case.
