“…Snowmaking, by contrast, is primarily designed to reduce the snow supply risk to ski tourism by decreasing the frequency of snow scarce conditions on ski pistes through the addition of machine-made snow [14,18,19,23]. There are multiple interactions between snowmaking, the local climate (snowmaking can only proceed if the temperature remains sufficiently low), the local environment (water ressources, local ecosystems), the broader socio-economic functioning of ski tourism within mountain areas, and the influence of ski tourism on the climate through greenhouse gas emissions [7,14,18,19,23] (see Figure 1). Europe (see Figure 2 for the included mountain ranges) is the largest global ski tourism market, with about 50% of the world's total ski resorts and over 80% of the world's ski resorts with more than 1 million skier visits (i.e.…”
