Artificial snow? But why?• Artificial snow is small particles of ice• It is produced by a machine • The first commercially successful machines

were developed in the 1950s.

• The water is mixed with compressed air and pumped through a high powered fan.

• The fan can spray the mixture into the air. • At this point the snow may be analyzed.

How many people are there in the Alps?

Too much water and energy is needed.

Consequences

If you go on ski slopes in summer time, you can see how much

damage is caused by skiing.

Resource conflicts in mountains

Natural resources are always limited

Conflicts occur between traditional primary activities such as farming and developing economic activities that have a less environmentallysustainable approach towards natural resources.

The demands of the tourism industry for water and snow are increasing

Simultaneously the climate change leads to less available water and natural snow

The most water is needed in times of minimal discharge

Rivers dry out Consequences for the wildlife habitat
