Climate change and human health in Alpine environments: an interdisciplinary impact chain approach understanding today's risks to address tomorrow's challenges.

The European Alps, home to a blend of permanent residents and millions of annual tourists, are found to be particularly sensitive to climate change. This article employs the impact chain concept to explore the interplay between climate change and health in Alpine areas, offering an interdisciplinary assessment of current and future health consequences and potential adaptation strategies.Rising temperatures, shifting precipitation patterns and increasing extreme weather events have profound implications for the Alpine regions. Temperatures have risen significantly over the past century, with projections indicating further increases and more frequent heatwaves. These trends increase the risk of heat-related health issues especially for vulnerable groups, including the elderly, frail individuals, children and recreationists. Furthermore, changing precipitation patterns, glacier retreat and permafrost melting adversely impact slope stability increasing the risk of gravity-driven natural hazards like landslides, avalanches and rockfalls. This poses direct threats, elevates the risk of multi-casualty incidents and strains search and rescue teams.The environmental changes also impact Alpine flora and fauna, altering the distribution and transmission of vector-borne diseases. Such events directly impact healthcare administration and management programmes, which are already challenged by surges in tourism and ensuring access to care.In conclusion, Alpine regions must proactively address these climate change-related health risks through an interdisciplinary approach, considering both preventive and responsive adaptation strategies, which we describe in this article.
