Contested places in the age of overtourism – the case of the „Andräviertel" in Salzburg
1University of Duisburg-Essen, Germany; 2University of Salzburg, Austria
Sped up by ubiquitous computing, cloud technology, extended network paradigms, algorithmic processing and sorting, datafication and artificial intelligence, place becomes a “hybrid”, multi-layered construct that consists of technology, (social-) (inter-)action, post-human (Rose, 2017) decisions/agency, spatio-material determination (for example infrastructure), and digital extensibility (Adams, 1995, 2017). With a backdrop on social constructivist and SCOT perspectives, digital placemaking then becomes a process of the mutual or “the reciprocal shaping of technology, the social, and space/place” (Fast, Ljungberg, & Braunerhielm, 2019, p. 90). We assume that the notions of identity, community and memory become extendable across time and locality by means of digital placemaking.
Against this background, this paper seeks to examine how place is re- and co-constructed in the case of the “Andräviertel” in Salzburg, Austria which is on the threshold of becoming the new "trendy" area. Salzburg is known for overtourism and its strong tourist industry lobby which is in a state of permanent tension with needs and interests of the local community. Employing an online ethnographic approach, our first aim is to map how digital placemaking takes form for the Andräviertel. In a second step, we will analyse how dimensions of power, privilege and precariousness intersect with digital placemaking and the claiming of material places.
Measuring Ultrafine Particle Concentrations at Salzburg Airport: Using the Airport Closure due to Runway Reconstruction as a Natural Experiment

During April and May 2019 Salzburg Airport was closed for five weeks for runway renovation. As a result, landings and take-offs (LTOs) were impossible during this period. This offered a rare opportunity to carry out a field study to investigate the concentration of ultrafine particles prior to, during and after completion of the renovation work. As expected, the sharp particle concentration peaks resulting from LTOs during normal operation were no longer encountered at the measurement site, 140 m from the runway, during the construction phase. Towards the end of the airport closure, construction activity was all but completed and LTO activity was strictly limited to test purposes, which resulted in average ultrafine-particle concentrations between approximately 3,000 to 4,000 cm-3 (06-23 h average value). The reconstruction work itself and the high numbers of construction vehicles caused an increase in ultrafine-particle concentrations of an additional 1,000 to 2,000 cm-3 (06-23 h average value). In comparison, in the three weeks before and the three weeks after the closure, when airport operations were running as normal, concentrations were increased by 3,000 to 4,000 cm-3 (06-23 h average value).
