Abstract
Population numbers and structures are subject to constant changes and due to this; communities of Alpine regions do face specific challenges. A case study set in South Tyrol and following a transdisciplinary approach show which consequences of demographic change are perceived as most important by alpine municipalities. The paper outlines those strategic spatial planning and regional development approaches which may help to compensate the problem. The research is based on a participatory approach with socio-statistical analysis being used to identify possible areas of action. Areas identified include: (i) the adaptation of touristic infrastructures to demographically determined changes of tourists requirements and needs; (ii) the development of integration measures in order to cope with increasing in-migration; and (iii) the prevention of social isolation of seniors. The research is supported by local decision makers in the regions and scientists as well, and it results in concrete, collaborative and demographically relevant regional development projects.
