Analysing, assessing and safeguarding Alpine open spaces through spatial planning.

Alpine open spaces are becoming noticeably scarcer. In the Alps, this applies to the inherently limited area of permanent settlement, which in the case of Tyrol covers only 11.8 percent. The population is growing in many of the valleys and with it the infrastructure it requires. However, the open spaces at higher altitudes are also being successively fragmented and equipped with infrastructure (e.g. cable cars, hydro-electric plants) or subjected to increasingly intensive use (e.g. with electric mountain bikes). The preservation of open spaces in the Alps began in Bavaria as early as 1972 with the implementation of the Alpine Plan, which established spatial planning objec-tives. The Alpine Plan divided Bavarias Alpine region into three zones of varying traffic intensity, a true legislative innovation. Zone C was intended for nature conservation, which was still in its infancy at that time, and also aimed to reduce natural Alpine hazards. Primarily, however, this planning initiative was related to the role of the landscape as a setting for recreation in open spaces, i.e. leisure and tourism activities in natural surroundings. Today, there are similar, more or less successful initiatives in all of the German-speaking Alpine states and Switzerland. This publication aims to analyse, compare and describe these initiatives and to critically assess how they are formulated, how they work, and how they are implemented by planners.
