Abstract
Climate change is an evolving business reality influencing the sustainability of ski tourism worldwide. A new integrated model of the co-evolution of supply (27 ski areas) and demand-side (skier behaviour) climate change adaptation in the ski tourism market of Ontario, Canada is presented. Ski area operations are modeled under a high-emission 2050s scenario, with skier responses to altered operations informed by a survey of 2429 skiers. These market adaptive dynamics reveal new insights into differential climate risk, capturing patterns not apparent when considering only operational conditions of ski resorts. A decoupling of ski season length and skier visitation was found at four ski areas, where, despite average season length losses, visitation increased as a result of reduced competition. Simulated skier visit losses were smaller than reductions in season length, contributing to an increase in crowding. Growing the market of skiers was also identified as a critical adaptation strategy that could offset skier visit losses from shortened seasons. Climate change challenges the future sustainability of ski areas in this market in several ways: profitability of ski areas with substantially shorter seasons, increased snowmaking costs, crowding impacts on visitor experience, and potential overtourism at the few most climate resilient destinations.
